We're dividing 381690 by 91 
We want to divide 381690 by 91.

Going ahead to step 1:
When dividing 3 by 91, we get 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
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

Moving on to step 2:
If we divide 38 by 91, we get 0 and a remainder of 38.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 38, we end up with 38.
Include the next digit (1) from the dividend after 38, then repeat: 381 / 91

Let's proceed to step 3:
91 can be fit into 381 4 times, resulting in a remainder of 17.
Write down 4 as next digit of the result. 
Result so far: 4.0
The remainder is 17 after subtracting 364 from 381.
Include the next digit (6) from the dividend after 17, then repeat: 176 / 91

Step 4:
91 goes into 176 1 times with a remainder of 85.
The number 1 becomes the next digit in our result. 
Result so far: 41.0
Subtracting 91 from 176 leaves us with 85.
Grab the next digit (9) from the dividend, add it to 85, then carry on: 859 / 91

Going ahead to step 5:
91 can be fit into 859 9 times, resulting in a remainder of 40.
The number 9 becomes the next digit in our result. 
Result so far: 419.0
Subtracting 819 from 859 leaves us with 40.
Grab the next digit (0) from the dividend, add it to 40, then carry on: 400 / 91

Step 6:
91 can be fit into 400 4 times, resulting in a remainder of 36.
Put 4 as the next digit of the answer. 
Result so far: 4194.0
Subtracting 364 from 400 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 7:
The number 91 fits into 360 3 times, leaving a remainder of 87.
The number 3 becomes the next digit in our result. 
Result so far: 4194.3
The remainder is 87 after subtracting 273 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

Going ahead to step 8:
If we divide 870 by 91, we get 9 and a remainder of 51.
The next digit of our result is 9. 
Result so far: 4194.39
Subtract 819 from 870 to get 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Let's proceed to step 9:
The number 91 fits into 510 5 times, leaving a remainder of 55.
Record the quotient 5 as the next digit in the result. 
Result so far: 4194.395
If we subtract 455 from 510, we get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Step 10:
When dividing 550 by 91, we get 6 with a remainder of 4.
Record the quotient 6 as the next digit in the result. 
Result so far: 4194.3956
Subtract 546 from 550 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.

Moving on to step 11:
91 can be fit into 40 0 times, resulting in a remainder of 40.
The next digit of our result is 0. 
Result so far: 4194.3956
The remainder is 40 after subtracting 0 from 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 12:
91 can be fit into 400 4 times, resulting in a remainder of 36.
The next digit of our result is 4. 
Result so far: 4194.395604
Subtracting 364 from 400 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 13:
When dividing 360 by 91, we get 3 with a remainder of 87.
Put 3 as the next digit of the answer. 
Result so far: 4194.3956043
Subtracting 273 from 360 leaves us with 87.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

Moving on to step 14:
When dividing 870 by 91, we get 9 with a remainder of 51.
The next digit of our result is 9. 
Result so far: 4194.39560439
If we take 819 away from 870, we end up with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

After the division, we end up with 4194.39560439 and a remainder of 5.1e-08.
