We're dividing 81384681 by 381 
We want to divide 81384681 by 381.

Step 1:
381 goes into 8 0 times with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Bring next digit (1) of the dividend behind the 8 and repeat the process: 81 / 381

On to step 2:
381 can be fit into 81 0 times, resulting in a remainder of 81.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 81, we end up with 81.
Bring next digit (3) of the dividend behind the 81 and repeat the process: 813 / 381

On to step 3:
If we divide 813 by 381, we get 2 and a remainder of 51.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtracting 762 from 813 leaves us with 51.
Append the next digit (8) from the dividend to 51 and continue with: 518 / 381

Step 4:
If we divide 518 by 381, we get 1 and a remainder of 137.
Use 1 as the next digit of our solution. 
Result so far: 21.0
Subtract 381 from 518 to get 137.
Include the next digit (4) from the dividend after 137, then repeat: 1374 / 381

Moving on to step 5:
381 can be fit into 1374 3 times, resulting in a remainder of 231.
Use 3 as the next digit of our solution. 
Result so far: 213.0
Subtract 1143 from 1374 to get 231.
Include the next digit (6) from the dividend after 231, then repeat: 2316 / 381

Moving on to step 6:
If we divide 2316 by 381, we get 6 and a remainder of 30.
Record the quotient 6 as the next digit in the result. 
Result so far: 2136.0
The remainder is 30 after subtracting 2286 from 2316.
Grab the next digit (8) from the dividend, add it to 30, then carry on: 308 / 381

Moving on to step 7:
If we divide 308 by 381, we get 0 and a remainder of 308.
Write down 0 as next digit of the result. 
Result so far: 21360.0
Deduct 0 from 308 and we're left with 308.
Bring next digit (1) of the dividend behind the 308 and repeat the process: 3081 / 381

Moving on to step 8:
When dividing 3081 by 381, we get 8 with a remainder of 33.
Put 8 as the next digit of the answer. 
Result so far: 213608.0
Deduct 3048 from 3081 and we're left with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Advancing to step 9:
If we divide 330 by 381, we get 0 and a remainder of 330.
Write down 0 as next digit of the result. 
Result so far: 213608.0
If we subtract 0 from 330, we get 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

Going ahead to step 10:
3300 divided by 381 is 8 with a remainder of 252.
The number 8 becomes the next digit in our result. 
Result so far: 213608.08
If we subtract 3048 from 3300, we get 252.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2520, and continue the process.

Advancing to step 11:
When dividing 2520 by 381, we get 6 with a remainder of 234.
Write down 6 as next digit of the result. 
Result so far: 213608.086
Subtracting 2286 from 2520 leaves us with 234.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2340, and continue the process.

Moving on to step 12:
2340 divided by 381 is 6 with a remainder of 54.
Record the quotient 6 as the next digit in the result. 
Result so far: 213608.0866
If we take 2286 away from 2340, we end up with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

After the division, we end up with 213608.0866 and a remainder of 0.00054.
