We look at the division of 381031 by 91 
Let's see how many times 91 fits into 381031.

On to step 1:
If we divide 3 by 91, we get 0 and a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Include the next digit (8) from the dividend after 3, then repeat: 38 / 91

Going ahead to step 2:
91 goes into 38 0 times with a remainder of 38.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 38 leaves us with 38.
Include the next digit (1) from the dividend after 38, then repeat: 381 / 91

Going ahead to step 3:
The number 91 fits into 381 4 times, leaving a remainder of 17.
The next digit of our result is 4. 
Result so far: 4.0
Subtract 364 from 381 to get 17.
Grab the next digit (0) from the dividend, add it to 17, then carry on: 170 / 91

Let's proceed to step 4:
170 divided by 91 is 1 with a remainder of 79.
Use 1 as the next digit of our solution. 
Result so far: 41.0
Subtract 91 from 170 to get 79.
Append the next digit (3) from the dividend to 79 and continue with: 793 / 91

Step 5:
If we divide 793 by 91, we get 8 and a remainder of 65.
Write down 8 as next digit of the result. 
Result so far: 418.0
If we subtract 728 from 793, we get 65.
Fetch the next digit (1) from the dividend, attach it to 65 and continue: 651 / 91

On to step 6:
If we divide 651 by 91, we get 7 and a remainder of 14.
Use 7 as the next digit of our solution. 
Result so far: 4187.0
If we subtract 637 from 651, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 7:
91 goes into 140 1 times with a remainder of 49.
The number 1 becomes the next digit in our result. 
Result so far: 4187.1
Subtracting 91 from 140 leaves us with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Moving on to step 8:
91 can be fit into 490 5 times, resulting in a remainder of 35.
The number 5 becomes the next digit in our result. 
Result so far: 4187.15
Subtracting 455 from 490 leaves us 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.

On to step 9:
If we divide 350 by 91, we get 3 and a remainder of 77.
Put 3 as the next digit of the answer. 
Result so far: 4187.153
If we subtract 273 from 350, we get 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

On to step 10:
91 goes into 770 8 times with a remainder of 42.
Write down 8 as next digit of the result. 
Result so far: 4187.1538
Deduct 728 from 770 and we're left with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Advancing to step 11:
91 can be fit into 420 4 times, resulting in a remainder of 56.
The number 4 becomes the next digit in our result. 
Result so far: 4187.15384
Subtract 364 from 420 to get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Going ahead to step 12:
560 divided by 91 is 6 with a remainder of 14.
The next digit of our result is 6. 
Result so far: 4187.153846
Deduct 546 from 560 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 13:
140 divided by 91 is 1 with a remainder of 49.
Use 1 as the next digit of our solution. 
Result so far: 4187.1538461
Deduct 91 from 140 and we're left with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Step 14:
91 goes into 490 5 times with a remainder of 35.
The next digit of our result is 5. 
Result so far: 4187.15384615
Subtract 455 from 490 to get 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 4187.15384615 with a remainder of 3.5e-08.
