We look at the division of 615728 by 81 
Let's see how many times 81 fits into 615728.

Step 1:
6 divided by 81 is 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Grab the next digit (1) from the dividend, add it to 6, then carry on: 61 / 81

On to step 2:
81 can be fit into 61 0 times, resulting in a remainder of 61.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 61, we get 61.
Grab the next digit (5) from the dividend, add it to 61, then carry on: 615 / 81

Let's proceed to step 3:
When dividing 615 by 81, we get 7 with a remainder of 48.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
The remainder is 48 after subtracting 567 from 615.
Append the next digit (7) from the dividend to 48 and continue with: 487 / 81

Going ahead to step 4:
When dividing 487 by 81, we get 6 with a remainder of 1.
Use 6 as the next digit of our solution. 
Result so far: 76.0
Deduct 486 from 487 and we're left with 1.
Take the next digit (2) from the dividend and append it to 1, then repeat: 12 / 81

Going ahead to step 5:
The number 81 fits into 12 0 times, leaving a remainder of 12.
Use 0 as the next digit of our solution. 
Result so far: 760.0
If we take 0 away from 12, we end up with 12.
Append the next digit (8) from the dividend to 12 and continue with: 128 / 81

Going ahead to step 6:
When dividing 128 by 81, we get 1 with a remainder of 47.
Write down 1 as next digit of the result. 
Result so far: 7601.0
Deduct 81 from 128 and we're left with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Advancing to step 7:
81 goes into 470 5 times with a remainder of 65.
Put 5 as the next digit of the answer. 
Result so far: 7601.5
Subtract 405 from 470 to get 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Going ahead to step 8:
The number 81 fits into 650 8 times, leaving a remainder of 2.
Use 8 as the next digit of our solution. 
Result so far: 7601.58
The remainder is 2 after subtracting 648 from 650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 9:
81 can be fit into 20 0 times, resulting in a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 7601.58
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 10:
The number 81 fits into 200 2 times, leaving a remainder of 38.
Use 2 as the next digit of our solution. 
Result so far: 7601.5802
Deduct 162 from 200 and we're left with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Let's proceed to step 11:
If we divide 380 by 81, we get 4 and a remainder of 56.
Use 4 as the next digit of our solution. 
Result so far: 7601.58024
If we subtract 324 from 380, we get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

On to step 12:
When dividing 560 by 81, we get 6 with a remainder of 74.
Record the quotient 6 as the next digit in the result. 
Result so far: 7601.580246
Deduct 486 from 560 and we're left with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Going ahead to step 13:
740 divided by 81 is 9 with a remainder of 11.
The next digit of our result is 9. 
Result so far: 7601.5802469
Subtract 729 from 740 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 14:
81 goes into 110 1 times with a remainder of 29.
The number 1 becomes the next digit in our result. 
Result so far: 7601.58024691
Subtracting 81 from 110 leaves us with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

The final outcome is 7601.58024691, with a leftover of 2.9e-08.
