Let's divide 431116 by 81
We want to divide 431116 by 81.

On to step 1:
81 can be fit into 4 0 times, resulting in a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Fetch the next digit (3) from the dividend, attach it to 4 and continue: 43 / 81

Step 2:
When dividing 43 by 81, we get 0 with a remainder of 43.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 43, we get 43.
Append the next digit (1) from the dividend to 43 and continue with: 431 / 81

Moving on to step 3:
If we divide 431 by 81, we get 5 and a remainder of 26.
Put 5 as the next digit of the answer. 
Result so far: 5.0
If we take 405 away from 431, we end up with 26.
Include the next digit (1) from the dividend after 26, then repeat: 261 / 81

Going ahead to step 4:
81 goes into 261 3 times with a remainder of 18.
Record the quotient 3 as the next digit in the result. 
Result so far: 53.0
If we subtract 243 from 261, we get 18.
Include the next digit (1) from the dividend after 18, then repeat: 181 / 81

Advancing to step 5:
When dividing 181 by 81, we get 2 with a remainder of 19.
The number 2 becomes the next digit in our result. 
Result so far: 532.0
The remainder is 19 after subtracting 162 from 181.
Fetch the next digit (6) from the dividend, attach it to 19 and continue: 196 / 81

On to step 6:
The number 81 fits into 196 2 times, leaving a remainder of 34.
Record the quotient 2 as the next digit in the result. 
Result so far: 5322.0
The remainder is 34 after subtracting 162 from 196.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Going ahead to step 7:
340 divided by 81 is 4 with a remainder of 16.
The number 4 becomes the next digit in our result. 
Result so far: 5322.4
Subtracting 324 from 340 leaves us 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.

On to step 8:
If we divide 160 by 81, we get 1 and a remainder of 79.
Use 1 as the next digit of our solution. 
Result so far: 5322.41
Deduct 81 from 160 and we're left 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 9:
81 goes into 790 9 times with a remainder of 61.
Put 9 as the next digit of the answer. 
Result so far: 5322.419
Subtracting 729 from 790 leaves us 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.

Advancing to step 10:
If we divide 610 by 81, we get 7 and a remainder of 43.
The number 7 becomes the next digit in our result. 
Result so far: 5322.4197
The remainder is 43 after subtracting 567 from 610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Let's proceed to step 11:
The number 81 fits into 430 5 times, leaving a remainder of 25.
Write down 5 as next digit of the result. 
Result so far: 5322.41975
Subtract 405 from 430 to 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 12:
81 goes into 250 3 times with a remainder of 7.
Put 3 as the next digit of the answer. 
Result so far: 5322.419753
Subtract 243 from 250 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Moving on to step 13:
81 can be fit into 70 0 times, resulting in a remainder of 70.
Write down 0 as next digit of the result. 
Result so far: 5322.419753
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.

Advancing to step 14:
The number 81 fits into 700 8 times, leaving a remainder of 52.
The next digit of our result is 8. 
Result so far: 5322.41975308
Deduct 648 from 700 and we're left 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.

The final result is 5322.41975308 with a remainder of 5.2e-08.
