Let's divide 912643 by 81
We want to divide 912643 by 81.

Step 1:
81 goes into 9 0 times with a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Bring next digit (1) of the dividend behind the 9 and repeat the process: 91 / 81

Let's proceed to step 2:
81 can be fit into 91 1 times, resulting in a remainder of 10.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 10 after subtracting 81 from 91.
Grab the next digit (2) from the dividend, add it to 10, then carry on: 102 / 81

Step 3:
If we divide 102 by 81, we get 1 and a remainder of 21.
The next digit of our result is 1. 
Result so far: 11.0
If we take 81 away from 102, we end up with 21.
Fetch the next digit (6) from the dividend, attach it to 21 and continue: 216 / 81

Let's proceed to step 4:
81 can be fit into 216 2 times, resulting in a remainder of 54.
The number 2 becomes the next digit in our result. 
Result so far: 112.0
If we subtract 162 from 216, we get 54.
Append the next digit (4) from the dividend to 54 and continue with: 544 / 81

Step 5:
When dividing 544 by 81, we get 6 with a remainder of 58.
Record the quotient 6 as the next digit in the result. 
Result so far: 1126.0
Subtract 486 from 544 to get 58.
Grab the next digit (3) from the dividend, add it to 58, then carry on: 583 / 81

Step 6:
When dividing 583 by 81, we get 7 with a remainder of 16.
Write down 7 as next digit of the result. 
Result so far: 11267.0
Deduct 567 from 583 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 7:
When dividing 160 by 81, we get 1 with a remainder of 79.
Record the quotient 1 as the next digit in the result. 
Result so far: 11267.1
Subtracting 81 from 160 leaves us with 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Going ahead to step 8:
790 divided by 81 is 9 with a remainder of 61.
The next digit of our result is 9. 
Result so far: 11267.19
If we take 729 away from 790, we end up with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Let's proceed to step 9:
When dividing 610 by 81, we get 7 with a remainder of 43.
Record the quotient 7 as the next digit in the result. 
Result so far: 11267.197
Subtracting 567 from 610 leaves us with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

On to step 10:
81 goes into 430 5 times with a remainder of 25.
The number 5 becomes the next digit in our result. 
Result so far: 11267.1975
If we subtract 405 from 430, we get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

On to step 11:
If we divide 250 by 81, we get 3 and a remainder of 7.
Record the quotient 3 as the next digit in the result. 
Result so far: 11267.19753
The remainder is 7 after subtracting 243 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 12:
If we divide 70 by 81, we get 0 and a remainder of 70.
The number 0 becomes the next digit in our result. 
Result so far: 11267.19753
Deduct 0 from 70 and we're left with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Going ahead to step 13:
700 divided by 81 is 8 with a remainder of 52.
Record the quotient 8 as the next digit in the result. 
Result so far: 11267.1975308
Subtracting 648 from 700 leaves us with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Let's proceed to step 14:
If we divide 520 by 81, we get 6 and a remainder of 34.
Write down 6 as next digit of the result. 
Result so far: 11267.19753086
Deduct 486 from 520 and we're left with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

After the division, we end up with 11267.19753086 and a remainder of 3.4e-08.
