We look at the division of 38183912 by 81 
We want to divide 38183912 by 81.

On to step 1:
81 can be fit into 3 0 times, resulting in a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Grab the next digit (8) from the dividend, add it to 3, then carry on: 38 / 81

Moving on to step 2:
The number 81 fits into 38 0 times, leaving a remainder of 38.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 38 to get 38.
Fetch the next digit (1) from the dividend, attach it to 38 and continue: 381 / 81

Going ahead to step 3:
If we divide 381 by 81, we get 4 and a remainder of 57.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
If we subtract 324 from 381, we get 57.
Include the next digit (8) from the dividend after 57, then repeat: 578 / 81

Step 4:
81 can be fit into 578 7 times, resulting in a remainder of 11.
The number 7 becomes the next digit in our result. 
Result so far: 47.0
Subtracting 567 from 578 leaves us with 11.
Fetch the next digit (3) from the dividend, attach it to 11 and continue: 113 / 81

Going ahead to step 5:
If we divide 113 by 81, we get 1 and a remainder of 32.
Put 1 as the next digit of the answer. 
Result so far: 471.0
If we take 81 away from 113, we end up with 32.
Grab the next digit (9) from the dividend, add it to 32, then carry on: 329 / 81

Going ahead to step 6:
81 goes into 329 4 times with a remainder of 5.
Use 4 as the next digit of our solution. 
Result so far: 4714.0
Subtracting 324 from 329 leaves us with 5.
Include the next digit (1) from the dividend after 5, then repeat: 51 / 81

Advancing to step 7:
When dividing 51 by 81, we get 0 with a remainder of 51.
The next digit of our result is 0. 
Result so far: 47140.0
Deduct 0 from 51 and we're left with 51.
Grab the next digit (2) from the dividend, add it to 51, then carry on: 512 / 81

On to step 8:
The number 81 fits into 512 6 times, leaving a remainder of 26.
The number 6 becomes the next digit in our result. 
Result so far: 471406.0
The remainder is 26 after subtracting 486 from 512.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

On to step 9:
When dividing 260 by 81, we get 3 with a remainder of 17.
Put 3 as the next digit of the answer. 
Result so far: 471406.3
If we take 243 away from 260, we end up with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Moving on to step 10:
81 can be fit into 170 2 times, resulting in a remainder of 8.
Record the quotient 2 as the next digit in the result. 
Result so far: 471406.32
Subtract 162 from 170 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 11:
The number 81 fits into 80 0 times, leaving a remainder of 80.
Put 0 as the next digit of the answer. 
Result so far: 471406.32
Subtract 0 from 80 to get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Step 12:
81 can be fit into 800 9 times, resulting in a remainder of 71.
Write down 9 as next digit of the result. 
Result so far: 471406.3209
The remainder is 71 after subtracting 729 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Moving on to step 13:
If we divide 710 by 81, we get 8 and a remainder of 62.
The next digit of our result is 8. 
Result so far: 471406.32098
Subtracting 648 from 710 leaves us with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Advancing to step 14:
The number 81 fits into 620 7 times, leaving a remainder of 53.
The number 7 becomes the next digit in our result. 
Result so far: 471406.320987
The remainder is 53 after subtracting 567 from 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Going ahead to step 15:
The number 81 fits into 530 6 times, leaving a remainder of 44.
Use 6 as the next digit of our solution. 
Result so far: 471406.3209876
If we subtract 486 from 530, we get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Going ahead to step 16:
If we divide 440 by 81, we get 5 and a remainder of 35.
The next digit of our result is 5. 
Result so far: 471406.32098765
If we take 405 away from 440, we end up with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

The final result is 471406.32098765 with a remainder of 3.5e-08.
