We're dividing 79937 by 81 
We want to figure out the number of times 79937 can be divided by 81.

Advancing to step 1:
The number 81 fits into 7 0 times, leaving a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Fetch the next digit (9) from the dividend, attach it to 7 and continue: 79 / 81

Going ahead to step 2:
If we divide 79 by 81, we get 0 and a remainder of 79.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 79, we end up with 79.
Append the next digit (9) from the dividend to 79 and continue with: 799 / 81

Moving on to step 3:
81 goes into 799 9 times with a remainder of 70.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
Subtract 729 from 799 to get 70.
Include the next digit (3) from the dividend after 70, then repeat: 703 / 81

On to step 4:
If we divide 703 by 81, we get 8 and a remainder of 55.
Record the quotient 8 as the next digit in the result. 
Result so far: 98.0
The remainder is 55 after subtracting 648 from 703.
Include the next digit (7) from the dividend after 55, then repeat: 557 / 81

Moving on to step 5:
If we divide 557 by 81, we get 6 and a remainder of 71.
Put 6 as the next digit of the answer. 
Result so far: 986.0
Subtract 486 from 557 to get 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Moving on to step 6:
710 divided by 81 is 8 with a remainder of 62.
Write down 8 as next digit of the result. 
Result so far: 986.8
The remainder is 62 after subtracting 648 from 710.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Going ahead to step 7:
When dividing 620 by 81, we get 7 with a remainder of 53.
The next digit of our result is 7. 
Result so far: 986.87
The remainder is 53 after subtracting 567 from 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Moving on to step 8:
When dividing 530 by 81, we get 6 with a remainder of 44.
Write down 6 as next digit of the result. 
Result so far: 986.876
If we take 486 away from 530, we end up with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Advancing to step 9:
81 goes into 440 5 times with a remainder of 35.
Write down 5 as next digit of the result. 
Result so far: 986.8765
If we subtract 405 from 440, we get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Let's proceed to step 10:
81 goes into 350 4 times with a remainder of 26.
The number 4 becomes the next digit in our result. 
Result so far: 986.87654
Deduct 324 from 350 and we're left with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Advancing to step 11:
If we divide 260 by 81, we get 3 and a remainder of 17.
Write down 3 as next digit of the result. 
Result so far: 986.876543
Subtracting 243 from 260 leaves us with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Advancing to step 12:
81 goes into 170 2 times with a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 986.8765432
If we subtract 162 from 170, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 13:
81 goes into 80 0 times with a remainder of 80.
Write down 0 as next digit of the result. 
Result so far: 986.8765432
If we take 0 away from 80, we end up 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.

The final result is 986.8765432 with a remainder of 8e-08.
