Let's divide 790356 by 81
We want to figure out the number of times 790356 can be divided by 81.

Going ahead to step 1:
If we divide 7 by 81, we get 0 and a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Take the next digit (9) from the dividend and append it to 7, then repeat: 79 / 81

Advancing to step 2:
When dividing 79 by 81, we get 0 with a remainder of 79.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 79 to get 79.
Fetch the next digit (0) from the dividend, attach it to 79 and continue: 790 / 81

On to step 3:
81 can be fit into 790 9 times, resulting in a remainder of 61.
Write down 9 as next digit of the result. 
Result so far: 9.0
Subtract 729 from 790 to get 61.
Take the next digit (3) from the dividend and append it to 61, then repeat: 613 / 81

Advancing to step 4:
613 divided by 81 is 7 with a remainder of 46.
The next digit of our result is 7. 
Result so far: 97.0
If we subtract 567 from 613, we get 46.
Bring next digit (5) of the dividend behind the 46 and repeat the process: 465 / 81

On to step 5:
465 divided by 81 is 5 with a remainder of 60.
Record the quotient 5 as the next digit in the result. 
Result so far: 975.0
The remainder is 60 after subtracting 405 from 465.
Append the next digit (6) from the dividend to 60 and continue with: 606 / 81

Moving on to step 6:
81 can be fit into 606 7 times, resulting in a remainder of 39.
Write down 7 as next digit of the result. 
Result so far: 9757.0
The remainder is 39 after subtracting 567 from 606.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Step 7:
81 can be fit into 390 4 times, resulting in a remainder of 66.
The next digit of our result is 4. 
Result so far: 9757.4
The remainder is 66 after subtracting 324 from 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Moving on to step 8:
81 can be fit into 660 8 times, resulting in a remainder of 12.
Put 8 as the next digit of the answer. 
Result so far: 9757.48
Deduct 648 from 660 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 9:
81 can be fit into 120 1 times, resulting in a remainder of 39.
The number 1 becomes the next digit in our result. 
Result so far: 9757.481
If we subtract 81 from 120, we get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Going ahead to step 10:
81 can be fit into 390 4 times, resulting in a remainder of 66.
Record the quotient 4 as the next digit in the result. 
Result so far: 9757.4814
If we take 324 away from 390, we end up with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Moving on to step 11:
81 goes into 660 8 times with a remainder of 12.
The number 8 becomes the next digit in our result. 
Result so far: 9757.48148
Deduct 648 from 660 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 12:
81 can be fit into 120 1 times, resulting in a remainder of 39.
Record the quotient 1 as the next digit in the result. 
Result so far: 9757.481481
If we subtract 81 from 120, we get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Going ahead to step 13:
The number 81 fits into 390 4 times, leaving a remainder of 66.
Record the quotient 4 as the next digit in the result. 
Result so far: 9757.4814814
The remainder is 66 after subtracting 324 from 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Step 14:
660 divided by 81 is 8 with a remainder of 12.
Use 8 as the next digit of our solution. 
Result so far: 9757.48148148
Subtract 648 from 660 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

The final result is 9757.48148148 with a remainder of 1.2e-08.
