We look at the division of 10105216 by 312 
We're looking to find how many times 312 goes into 10105216.

Step 1:
If we divide 1 by 312, we get 0 and a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Grab the next digit (0) from the dividend, add it to 1, then carry on: 10 / 312

Step 2:
When dividing 10 by 312, we get 0 with a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 10, we get 10.
Append the next digit (1) from the dividend to 10 and continue with: 101 / 312

On to step 3:
The number 312 fits into 101 0 times, leaving a remainder of 101.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 101 after subtracting 0 from 101.
Include the next digit (0) from the dividend after 101, then repeat: 1010 / 312

Going ahead to step 4:
312 can be fit into 1010 3 times, resulting in a remainder of 74.
The next digit of our result is 3. 
Result so far: 3.0
The remainder is 74 after subtracting 936 from 1010.
Take the next digit (5) from the dividend and append it to 74, then repeat: 745 / 312

Let's proceed to step 5:
When dividing 745 by 312, we get 2 with a remainder of 121.
Use 2 as the next digit of our solution. 
Result so far: 32.0
If we take 624 away from 745, we end up with 121.
Include the next digit (2) from the dividend after 121, then repeat: 1212 / 312

Let's proceed to step 6:
The number 312 fits into 1212 3 times, leaving a remainder of 276.
Use 3 as the next digit of our solution. 
Result so far: 323.0
Subtracting 936 from 1212 leaves us with 276.
Append the next digit (1) from the dividend to 276 and continue with: 2761 / 312

Step 7:
312 can be fit into 2761 8 times, resulting in a remainder of 265.
Use 8 as the next digit of our solution. 
Result so far: 3238.0
Subtract 2496 from 2761 to get 265.
Take the next digit (6) from the dividend and append it to 265, then repeat: 2656 / 312

On to step 8:
When dividing 2656 by 312, we get 8 with a remainder of 160.
Write down 8 as next digit of the result. 
Result so far: 32388.0
If we subtract 2496 from 2656, we get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Advancing to step 9:
1600 divided by 312 is 5 with a remainder of 40.
The number 5 becomes the next digit in our result. 
Result so far: 32388.5
Subtracting 1560 from 1600 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 10:
312 goes into 400 1 times with a remainder of 88.
Write down 1 as next digit of the result. 
Result so far: 32388.51
The remainder is 88 after subtracting 312 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Let's proceed to step 11:
When dividing 880 by 312, we get 2 with a remainder of 256.
Write down 2 as next digit of the result. 
Result so far: 32388.512
Subtract 624 from 880 to get 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

Advancing to step 12:
312 can be fit into 2560 8 times, resulting in a remainder of 64.
Use 8 as the next digit of our solution. 
Result so far: 32388.5128
Subtracting 2496 from 2560 leaves us with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

On to step 13:
When dividing 640 by 312, we get 2 with a remainder of 16.
The next digit of our result is 2. 
Result so far: 32388.51282
Subtract 624 from 640 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 14:
If we divide 160 by 312, we get 0 and a remainder of 160.
Use 0 as the next digit of our solution. 
Result so far: 32388.51282
The remainder is 160 after subtracting 0 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Let's proceed to step 15:
When dividing 1600 by 312, we get 5 with a remainder of 40.
Put 5 as the next digit of the answer. 
Result so far: 32388.5128205
Subtract 1560 from 1600 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 16:
When dividing 400 by 312, we get 1 with a remainder of 88.
Record the quotient 1 as the next digit in the result. 
Result so far: 32388.51282051
If we subtract 312 from 400, we get 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

The final outcome is 32388.51282051, with a leftover of 8.8e-08.
