We divide 709721 by 90
We're looking to find how many times 90 goes into 709721.

Step 1:
7 divided by 90 is 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Append the next digit (0) from the dividend to 7 and continue with: 70 / 90

Let's proceed to step 2:
If we divide 70 by 90, we get 0 and a remainder of 70.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 70, we end up with 70.
Append the next digit (9) from the dividend to 70 and continue with: 709 / 90

Let's proceed to step 3:
709 divided by 90 is 7 with a remainder of 79.
Put 7 as the next digit of the answer. 
Result so far: 7.0
Subtracting 630 from 709 leaves us with 79.
Include the next digit (7) from the dividend after 79, then repeat: 797 / 90

Advancing to step 4:
When dividing 797 by 90, we get 8 with a remainder of 77.
Write down 8 as next digit of the result. 
Result so far: 78.0
The remainder is 77 after subtracting 720 from 797.
Take the next digit (2) from the dividend and append it to 77, then repeat: 772 / 90

On to step 5:
When dividing 772 by 90, we get 8 with a remainder of 52.
Write down 8 as next digit of the result. 
Result so far: 788.0
If we take 720 away from 772, we end up with 52.
Fetch the next digit (1) from the dividend, attach it to 52 and continue: 521 / 90

Step 6:
When dividing 521 by 90, we get 5 with a remainder of 71.
The number 5 becomes the next digit in our result. 
Result so far: 7885.0
Deduct 450 from 521 and we're left with 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Step 7:
90 goes into 710 7 times with a remainder of 80.
Record the quotient 7 as the next digit in the result. 
Result so far: 7885.7
Subtracting 630 from 710 leaves us with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Advancing to step 8:
When dividing 800 by 90, we get 8 with a remainder of 80.
Record the quotient 8 as the next digit in the result. 
Result so far: 7885.78
Subtracting 720 from 800 leaves us with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Going ahead to step 9:
800 divided by 90 is 8 with a remainder of 80.
Write down 8 as next digit of the result. 
Result so far: 7885.788
Subtract 720 from 800 to get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

The quotient of the division is 7885.788, and the remainder is 0.008.
