We're dividing 331396 by 91 
We want to divide 331396 by 91.

Going ahead to step 1:
91 can be fit into 3 0 times, resulting in a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Take the next digit (3) from the dividend and append it to 3, then repeat: 33 / 91

Moving on to step 2:
91 goes into 33 0 times with a remainder of 33.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 33, we end up with 33.
Bring next digit (1) of the dividend behind the 33 and repeat the process: 331 / 91

Step 3:
If we divide 331 by 91, we get 3 and a remainder of 58.
Write down 3 as next digit of the result. 
Result so far: 3.0
If we take 273 away from 331, we end up with 58.
Bring next digit (3) of the dividend behind the 58 and repeat the process: 583 / 91

Moving on to step 4:
When dividing 583 by 91, we get 6 with a remainder of 37.
The number 6 becomes the next digit in our result. 
Result so far: 36.0
The remainder is 37 after subtracting 546 from 583.
Take the next digit (9) from the dividend and append it to 37, then repeat: 379 / 91

Advancing to step 5:
379 divided by 91 is 4 with a remainder of 15.
Write down 4 as next digit of the result. 
Result so far: 364.0
The remainder is 15 after subtracting 364 from 379.
Bring next digit (6) of the dividend behind the 15 and repeat the process: 156 / 91

On to step 6:
When dividing 156 by 91, we get 1 with a remainder of 65.
Use 1 as the next digit of our solution. 
Result so far: 3641.0
Subtracting 91 from 156 leaves us with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

On to step 7:
91 can be fit into 650 7 times, resulting in a remainder of 13.
Use 7 as the next digit of our solution. 
Result so far: 3641.7
Deduct 637 from 650 and we're left with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Moving on to step 8:
130 divided by 91 is 1 with a remainder of 39.
Use 1 as the next digit of our solution. 
Result so far: 3641.71
If we subtract 91 from 130, we get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Moving on to step 9:
91 goes into 390 4 times with a remainder of 26.
Put 4 as the next digit of the answer. 
Result so far: 3641.714
The remainder is 26 after subtracting 364 from 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

On to step 10:
91 can be fit into 260 2 times, resulting in a remainder of 78.
Use 2 as the next digit of our solution. 
Result so far: 3641.7142
Deduct 182 from 260 and we're left with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Let's proceed to step 11:
The number 91 fits into 780 8 times, leaving a remainder of 52.
Put 8 as the next digit of the answer. 
Result so far: 3641.71428
Subtract 728 from 780 to get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Advancing to step 12:
If we divide 520 by 91, we get 5 and a remainder of 65.
Put 5 as the next digit of the answer. 
Result so far: 3641.714285
Subtracting 455 from 520 leaves us with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Step 13:
650 divided by 91 is 7 with a remainder of 13.
Use 7 as the next digit of our solution. 
Result so far: 3641.7142857
Subtract 637 from 650 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Let's proceed to step 14:
The number 91 fits into 130 1 times, leaving a remainder of 39.
Write down 1 as next digit of the result. 
Result so far: 3641.71428571
Subtracting 91 from 130 leaves us with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

After the division, we end up with 3641.71428571 and a remainder of 3.9e-08.
