We look at the division of 355523 by 91 
Our goal is to divide 355523 by 91.

Going ahead to step 1:
The number 91 fits into 3 0 times, leaving a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Include the next digit (5) from the dividend after 3, then repeat: 35 / 91

Let's proceed to step 2:
91 can be fit into 35 0 times, resulting in a remainder of 35.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 35 leaves us with 35.
Append the next digit (5) from the dividend to 35 and continue with: 355 / 91

Step 3:
When dividing 355 by 91, we get 3 with a remainder of 82.
Use 3 as the next digit of our solution. 
Result so far: 3.0
The remainder is 82 after subtracting 273 from 355.
Fetch the next digit (5) from the dividend, attach it to 82 and continue: 825 / 91

Advancing to step 4:
825 divided by 91 is 9 with a remainder of 6.
The next digit of our result is 9. 
Result so far: 39.0
If we take 819 away from 825, we end up with 6.
Take the next digit (2) from the dividend and append it to 6, then repeat: 62 / 91

Moving on to step 5:
When dividing 62 by 91, we get 0 with a remainder of 62.
The next digit of our result is 0. 
Result so far: 390.0
Subtracting 0 from 62 leaves us with 62.
Bring next digit (3) of the dividend behind the 62 and repeat the process: 623 / 91

On to step 6:
When dividing 623 by 91, we get 6 with a remainder of 77.
The number 6 becomes the next digit in our result. 
Result so far: 3906.0
If we take 546 away from 623, we end up with 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Let's proceed to step 7:
91 can be fit into 770 8 times, resulting in a remainder of 42.
The number 8 becomes the next digit in our result. 
Result so far: 3906.8
The remainder is 42 after subtracting 728 from 770.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

On to step 8:
420 divided by 91 is 4 with a remainder of 56.
The number 4 becomes the next digit in our result. 
Result so far: 3906.84
Deduct 364 from 420 and we're left with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

On to step 9:
91 goes into 560 6 times with a remainder of 14.
Write down 6 as next digit of the result. 
Result so far: 3906.846
The remainder is 14 after subtracting 546 from 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 10:
When dividing 140 by 91, we get 1 with a remainder of 49.
Use 1 as the next digit of our solution. 
Result so far: 3906.8461
Subtract 91 from 140 to get 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 11:
If we divide 490 by 91, we get 5 and a remainder of 35.
Put 5 as the next digit of the answer. 
Result so far: 3906.84615
If we take 455 away from 490, we end up 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.

Advancing to step 12:
The number 91 fits into 350 3 times, leaving a remainder of 77.
Use 3 as the next digit of our solution. 
Result so far: 3906.846153
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.

Step 13:
The number 91 fits into 770 8 times, leaving a remainder of 42.
The number 8 becomes the next digit in our result. 
Result so far: 3906.8461538
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.

Step 14:
91 can be fit into 420 4 times, resulting in a remainder of 56.
Record the quotient 4 as the next digit in the result. 
Result so far: 3906.84615384
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.

After the division, we end up with 3906.84615384 and a remainder of 5.6e-08.
