We're dividing 381091 by 99 
Our goal is to divide 381091 by 99.

Moving on to step 1:
If we divide 3 by 99, we get 0 and a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Bring next digit (8) of the dividend behind the 3 and repeat the process: 38 / 99

Going ahead to step 2:
99 can be fit into 38 0 times, resulting in a remainder of 38.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 38 to get 38.
Grab the next digit (1) from the dividend, add it to 38, then carry on: 381 / 99

Going ahead to step 3:
99 can be fit into 381 3 times, resulting in a remainder of 84.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Deduct 297 from 381 and we're left with 84.
Bring next digit (0) of the dividend behind the 84 and repeat the process: 840 / 99

Advancing to step 4:
99 can be fit into 840 8 times, resulting in a remainder of 48.
Record the quotient 8 as the next digit in the result. 
Result so far: 38.0
If we subtract 792 from 840, we get 48.
Take the next digit (9) from the dividend and append it to 48, then repeat: 489 / 99

Advancing to step 5:
When dividing 489 by 99, we get 4 with a remainder of 93.
Record the quotient 4 as the next digit in the result. 
Result so far: 384.0
If we take 396 away from 489, we end up with 93.
Include the next digit (1) from the dividend after 93, then repeat: 931 / 99

Let's proceed to step 6:
99 can be fit into 931 9 times, resulting in a remainder of 40.
Write down 9 as next digit of the result. 
Result so far: 3849.0
Subtract 891 from 931 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 7:
The number 99 fits into 400 4 times, leaving a remainder of 4.
The number 4 becomes the next digit in our result. 
Result so far: 3849.4
If we take 396 away from 400, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 8:
The number 99 fits into 40 0 times, leaving a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 3849.4
Deduct 0 from 40 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 9:
99 can be fit into 400 4 times, resulting in a remainder of 4.
Write down 4 as next digit of the result. 
Result so far: 3849.404
Subtract 396 from 400 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 10:
If we divide 40 by 99, we get 0 and a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 3849.404
Subtract 0 from 40 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 11:
99 goes into 400 4 times with a remainder of 4.
Put 4 as the next digit of the answer. 
Result so far: 3849.40404
If we take 396 away from 400, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 12:
The number 99 fits into 40 0 times, leaving a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 3849.40404
Subtracting 0 from 40 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 13:
99 goes into 400 4 times with a remainder of 4.
The number 4 becomes the next digit in our result. 
Result so far: 3849.4040404
Deduct 396 from 400 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 14:
99 goes into 40 0 times with a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 3849.4040404
Subtract 0 from 40 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

The final outcome is 3849.4040404, with a leftover of 4e-08.
