31615095 divided by 312 
We want to figure out the number of times 31615095 can be divided by 312.

On to step 1:
If we divide 3 by 312, we get 0 and a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Append the next digit (1) from the dividend to 3 and continue with: 31 / 312

Moving on to step 2:
When dividing 31 by 312, we get 0 with a remainder of 31.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 31 and we're left with 31.
Bring next digit (6) of the dividend behind the 31 and repeat the process: 316 / 312

On to step 3:
316 divided by 312 is 1 with a remainder of 4.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 312 from 316 leaves us with 4.
Include the next digit (1) from the dividend after 4, then repeat: 41 / 312

On to step 4:
41 divided by 312 is 0 with a remainder of 41.
The next digit of our result is 0. 
Result so far: 10.0
Subtract 0 from 41 to get 41.
Append the next digit (5) from the dividend to 41 and continue with: 415 / 312

On to step 5:
415 divided by 312 is 1 with a remainder of 103.
The number 1 becomes the next digit in our result. 
Result so far: 101.0
Deduct 312 from 415 and we're left with 103.
Fetch the next digit (0) from the dividend, attach it to 103 and continue: 1030 / 312

Step 6:
312 can be fit into 1030 3 times, resulting in a remainder of 94.
The next digit of our result is 3. 
Result so far: 1013.0
If we subtract 936 from 1030, we get 94.
Grab the next digit (9) from the dividend, add it to 94, then carry on: 949 / 312

Going ahead to step 7:
312 can be fit into 949 3 times, resulting in a remainder of 13.
The number 3 becomes the next digit in our result. 
Result so far: 10133.0
Subtract 936 from 949 to get 13.
Grab the next digit (5) from the dividend, add it to 13, then carry on: 135 / 312

Let's proceed to step 8:
135 divided by 312 is 0 with a remainder of 135.
Use 0 as the next digit of our solution. 
Result so far: 101330.0
The remainder is 135 after subtracting 0 from 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

Let's proceed to step 9:
The number 312 fits into 1350 4 times, leaving a remainder of 102.
Write down 4 as next digit of the result. 
Result so far: 101330.4
The remainder is 102 after subtracting 1248 from 1350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

Advancing to step 10:
When dividing 1020 by 312, we get 3 with a remainder of 84.
Put 3 as the next digit of the answer. 
Result so far: 101330.43
If we subtract 936 from 1020, we get 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Step 11:
312 can be fit into 840 2 times, resulting in a remainder of 216.
Record the quotient 2 as the next digit in the result. 
Result so far: 101330.432
If we subtract 624 from 840, we get 216.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

Step 12:
312 can be fit into 2160 6 times, resulting in a remainder of 288.
Record the quotient 6 as the next digit in the result. 
Result so far: 101330.4326
If we subtract 1872 from 2160, we get 288.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

Advancing to step 13:
When dividing 2880 by 312, we get 9 with a remainder of 72.
Record the quotient 9 as the next digit in the result. 
Result so far: 101330.43269
If we subtract 2808 from 2880, we get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Advancing to step 14:
312 can be fit into 720 2 times, resulting in a remainder of 96.
Use 2 as the next digit of our solution. 
Result so far: 101330.432692
Subtracting 624 from 720 leaves us with 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Step 15:
When dividing 960 by 312, we get 3 with a remainder of 24.
Write down 3 as next digit of the result. 
Result so far: 101330.4326923
Subtract 936 from 960 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 16:
The number 312 fits into 240 0 times, leaving a remainder of 240.
Record the quotient 0 as the next digit in the result. 
Result so far: 101330.4326923
If we subtract 0 from 240, we get 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

After the division, we end up with 101330.4326923 and a remainder of 2.4e-07.
