We divide 635136 by 81
Our goal is to divide 635136 by 81.

Going ahead to step 1:
6 divided by 81 is 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Bring next digit (3) of the dividend behind the 6 and repeat the process: 63 / 81

Moving on to step 2:
If we divide 63 by 81, we get 0 and a remainder of 63.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 63, we get 63.
Grab the next digit (5) from the dividend, add it to 63, then carry on: 635 / 81

Let's proceed to step 3:
The number 81 fits into 635 7 times, leaving a remainder of 68.
Use 7 as the next digit of our solution. 
Result so far: 7.0
Deduct 567 from 635 and we're left with 68.
Fetch the next digit (1) from the dividend, attach it to 68 and continue: 681 / 81

Let's proceed to step 4:
681 divided by 81 is 8 with a remainder of 33.
The number 8 becomes the next digit in our result. 
Result so far: 78.0
Subtracting 648 from 681 leaves us with 33.
Grab the next digit (3) from the dividend, add it to 33, then carry on: 333 / 81

On to step 5:
81 can be fit into 333 4 times, resulting in a remainder of 9.
The number 4 becomes the next digit in our result. 
Result so far: 784.0
Deduct 324 from 333 and we're left with 9.
Grab the next digit (6) from the dividend, add it to 9, then carry on: 96 / 81

On to step 6:
81 goes into 96 1 times with a remainder of 15.
Write down 1 as next digit of the result. 
Result so far: 7841.0
Subtracting 81 from 96 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 7:
If we divide 150 by 81, we get 1 and a remainder of 69.
Record the quotient 1 as the next digit in the result. 
Result so far: 7841.1
If we take 81 away from 150, we end up with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

On to step 8:
81 can be fit into 690 8 times, resulting in a remainder of 42.
Write down 8 as next digit of the result. 
Result so far: 7841.18
Subtracting 648 from 690 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Going ahead to step 9:
The number 81 fits into 420 5 times, leaving a remainder of 15.
The next digit of our result is 5. 
Result so far: 7841.185
Deduct 405 from 420 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 10:
The number 81 fits into 150 1 times, leaving a remainder of 69.
Record the quotient 1 as the next digit in the result. 
Result so far: 7841.1851
Deduct 81 from 150 and we're left with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Going ahead to step 11:
The number 81 fits into 690 8 times, leaving a remainder of 42.
Write down 8 as next digit of the result. 
Result so far: 7841.18518
Subtract 648 from 690 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Advancing to step 12:
If we divide 420 by 81, we get 5 and a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 7841.185185
Subtracting 405 from 420 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 13:
81 can be fit into 150 1 times, resulting in a remainder of 69.
Write down 1 as next digit of the result. 
Result so far: 7841.1851851
Subtract 81 from 150 to get 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Advancing to step 14:
81 can be fit into 690 8 times, resulting in a remainder of 42.
Record the quotient 8 as the next digit in the result. 
Result so far: 7841.18518518
Subtract 648 from 690 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

The final result is 7841.18518518 with a remainder of 4.2e-08.
