Let's divide 315958 by 91
We want to figure out the number of times 315958 can be divided by 91.

Going ahead to step 1:
When dividing 3 by 91, we get 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Bring next digit (1) of the dividend behind the 3 and repeat the process: 31 / 91

Moving on to step 2:
91 can be fit into 31 0 times, resulting in a remainder of 31.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 31 and we're left with 31.
Grab the next digit (5) from the dividend, add it to 31, then carry on: 315 / 91

On to step 3:
If we divide 315 by 91, we get 3 and a remainder of 42.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtracting 273 from 315 leaves us with 42.
Include the next digit (9) from the dividend after 42, then repeat: 429 / 91

Moving on to step 4:
429 divided by 91 is 4 with a remainder of 65.
Write down 4 as next digit of the result. 
Result so far: 34.0
The remainder is 65 after subtracting 364 from 429.
Include the next digit (5) from the dividend after 65, then repeat: 655 / 91

On to step 5:
If we divide 655 by 91, we get 7 and a remainder of 18.
Put 7 as the next digit of the answer. 
Result so far: 347.0
Deduct 637 from 655 and we're left with 18.
Bring next digit (8) of the dividend behind the 18 and repeat the process: 188 / 91

Let's proceed to step 6:
If we divide 188 by 91, we get 2 and a remainder of 6.
The number 2 becomes the next digit in our result. 
Result so far: 3472.0
Subtract 182 from 188 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 7:
60 divided by 91 is 0 with a remainder of 60.
Write down 0 as next digit of the result. 
Result so far: 3472.0
The remainder is 60 after subtracting 0 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 8:
If we divide 600 by 91, we get 6 and a remainder of 54.
Use 6 as the next digit of our solution. 
Result so far: 3472.06
The remainder is 54 after subtracting 546 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Going ahead to step 9:
91 can be fit into 540 5 times, resulting in a remainder of 85.
Write down 5 as next digit of the result. 
Result so far: 3472.065
If we take 455 away from 540, we end up with 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Step 10:
91 can be fit into 850 9 times, resulting in a remainder of 31.
Write down 9 as next digit of the result. 
Result so far: 3472.0659
Subtract 819 from 850 to get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Moving on to step 11:
If we divide 310 by 91, we get 3 and a remainder of 37.
Record the quotient 3 as the next digit in the result. 
Result so far: 3472.06593
If we take 273 away from 310, we end up with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Step 12:
370 divided by 91 is 4 with a remainder of 6.
Record the quotient 4 as the next digit in the result. 
Result so far: 3472.065934
Subtract 364 from 370 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 13:
91 goes into 60 0 times with a remainder of 60.
The number 0 becomes the next digit in our result. 
Result so far: 3472.065934
The remainder is 60 after subtracting 0 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 14:
When dividing 600 by 91, we get 6 with a remainder of 54.
The number 6 becomes the next digit in our result. 
Result so far: 3472.06593406
If we subtract 546 from 600, we get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

After the division, we end up with 3472.06593406 and a remainder of 5.4e-08.
