We look at the division of 81538857 by 381 
We're looking to find how many times 381 goes into 81538857.

Advancing to step 1:
When dividing 8 by 381, we get 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Take the next digit (1) from the dividend and append it to 8, then repeat: 81 / 381

Going ahead to step 2:
The number 381 fits into 81 0 times, leaving a remainder of 81.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 81, we get 81.
Include the next digit (5) from the dividend after 81, then repeat: 815 / 381

Step 3:
381 goes into 815 2 times with a remainder of 53.
Put 2 as the next digit of the answer. 
Result so far: 2.0
The remainder is 53 after subtracting 762 from 815.
Grab the next digit (3) from the dividend, add it to 53, then carry on: 533 / 381

On to step 4:
381 goes into 533 1 times with a remainder of 152.
The number 1 becomes the next digit in our result. 
Result so far: 21.0
Deduct 381 from 533 and we're left with 152.
Take the next digit (8) from the dividend and append it to 152, then repeat: 1528 / 381

Moving on to step 5:
381 goes into 1528 4 times with a remainder of 4.
Write down 4 as next digit of the result. 
Result so far: 214.0
Subtract 1524 from 1528 to get 4.
Take the next digit (8) from the dividend and append it to 4, then repeat: 48 / 381

Step 6:
381 goes into 48 0 times with a remainder of 48.
Use 0 as the next digit of our solution. 
Result so far: 2140.0
Deduct 0 from 48 and we're left with 48.
Include the next digit (5) from the dividend after 48, then repeat: 485 / 381

Step 7:
If we divide 485 by 381, we get 1 and a remainder of 104.
The number 1 becomes the next digit in our result. 
Result so far: 21401.0
Deduct 381 from 485 and we're left with 104.
Include the next digit (7) from the dividend after 104, then repeat: 1047 / 381

Step 8:
When dividing 1047 by 381, we get 2 with a remainder of 285.
Write down 2 as next digit of the result. 
Result so far: 214012.0
The remainder is 285 after subtracting 762 from 1047.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2850, and continue the process.

Moving on to step 9:
When dividing 2850 by 381, we get 7 with a remainder of 183.
Use 7 as the next digit of our solution. 
Result so far: 214012.7
If we take 2667 away from 2850, we end up with 183.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1830, and continue the process.

Advancing to step 10:
If we divide 1830 by 381, we get 4 and a remainder of 306.
Use 4 as the next digit of our solution. 
Result so far: 214012.74
Subtracting 1524 from 1830 leaves us with 306.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3060, and continue the process.

Advancing to step 11:
When dividing 3060 by 381, we get 8 with a remainder of 12.
Record the quotient 8 as the next digit in the result. 
Result so far: 214012.748
Subtracting 3048 from 3060 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 12:
If we divide 120 by 381, we get 0 and a remainder of 120.
The number 0 becomes the next digit in our result. 
Result so far: 214012.748
Subtracting 0 from 120 leaves us with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Going ahead to step 13:
The number 381 fits into 1200 3 times, leaving a remainder of 57.
Put 3 as the next digit of the answer. 
Result so far: 214012.74803
The remainder is 57 after subtracting 1143 from 1200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Going ahead to step 14:
381 goes into 570 1 times with a remainder of 189.
Put 1 as the next digit of the answer. 
Result so far: 214012.748031
Subtracting 381 from 570 leaves us with 189.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1890, and continue the process.

Step 15:
If we divide 1890 by 381, we get 4 and a remainder of 366.
The next digit of our result is 4. 
Result so far: 214012.7480314
The remainder is 366 after subtracting 1524 from 1890.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3660, and continue the process.

Step 16:
The number 381 fits into 3660 9 times, leaving a remainder of 231.
Write down 9 as next digit of the result. 
Result so far: 214012.74803149
If we take 3429 away from 3660, we end up with 231.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2310, and continue the process.

After the division, we end up with 214012.74803149 and a remainder of 2.31e-07.
