We look at the division of 316215 by 91 
We want to divide 316215 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
Subtract 0 from 3 to get 3.
Append the next digit (1) from the dividend to 3 and continue with: 31 / 91

Moving on to step 2:
The number 91 fits into 31 0 times, leaving a remainder of 31.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 31 leaves us with 31.
Include the next digit (6) from the dividend after 31, then repeat: 316 / 91

Let's proceed to step 3:
If we divide 316 by 91, we get 3 and a remainder of 43.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtract 273 from 316 to get 43.
Grab the next digit (2) from the dividend, add it to 43, then carry on: 432 / 91

Moving on to step 4:
When dividing 432 by 91, we get 4 with a remainder of 68.
The number 4 becomes the next digit in our result. 
Result so far: 34.0
The remainder is 68 after subtracting 364 from 432.
Include the next digit (1) from the dividend after 68, then repeat: 681 / 91

Moving on to step 5:
When dividing 681 by 91, we get 7 with a remainder of 44.
Write down 7 as next digit of the result. 
Result so far: 347.0
The remainder is 44 after subtracting 637 from 681.
Append the next digit (5) from the dividend to 44 and continue with: 445 / 91

Step 6:
91 goes into 445 4 times with a remainder of 81.
Put 4 as the next digit of the answer. 
Result so far: 3474.0
If we subtract 364 from 445, we get 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Advancing to step 7:
When dividing 810 by 91, we get 8 with a remainder of 82.
Write down 8 as next digit of the result. 
Result so far: 3474.8
If we take 728 away from 810, we end up with 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

On to step 8:
91 goes into 820 9 times with a remainder of 1.
The next digit of our result is 9. 
Result so far: 3474.89
If we take 819 away from 820, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 9:
10 divided by 91 is 0 with a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 3474.89
Subtracting 0 from 10 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 10:
100 divided by 91 is 1 with a remainder of 9.
Use 1 as the next digit of our solution. 
Result so far: 3474.8901
Subtracting 91 from 100 leaves us with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 11:
The number 91 fits into 90 0 times, leaving a remainder of 90.
The next digit of our result is 0. 
Result so far: 3474.8901
The remainder is 90 after subtracting 0 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Step 12:
91 can be fit into 900 9 times, resulting in a remainder of 81.
The number 9 becomes the next digit in our result. 
Result so far: 3474.890109
Subtract 819 from 900 to get 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Advancing to step 13:
If we divide 810 by 91, we get 8 and a remainder of 82.
Put 8 as the next digit of the answer. 
Result so far: 3474.8901098
The remainder is 82 after subtracting 728 from 810.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Advancing to step 14:
91 goes into 820 9 times with a remainder of 1.
Use 9 as the next digit of our solution. 
Result so far: 3474.89010989
The remainder is 1 after subtracting 819 from 820.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

After the division, we end up with 3474.89010989 and a remainder of 1e-09.
