Step 3.

Subtract the digit 6 from the

digit 7. 7 - 6 = 1. The remainder

is 1. The remainder must be less

than the divisor 3.

Step 4.

Since the remainder is less than

the divisor 3, bring down the next

digit, 5.

Step 5.

Divide the number 15 by 3.

15 ƒ 3 = 5. Write the 5 above

the 5 in ones position.

Step 6.

Multiply the divisor 3 by the

digit 5. 3 x 5 = 15. Write the

number 15.

Step 7.

Subtract the number 15 from 15.

15 - 15 = 0, indicating that the

calculation is complete.

Step 8.

Check by multiplying the quotient

by the divisor. 25 x 3 = 75.
