12679002 ÷ 312 
We want to figure out the number of times 12679002 can be divided by 312.

On to step 1:
If we divide 1 by 312, we get 0 and a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 312

Going ahead to step 2:
If we divide 12 by 312, we get 0 and a remainder of 12.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 12 and we're left with 12.
Fetch the next digit (6) from the dividend, attach it to 12 and continue: 126 / 312

Moving on to step 3:
126 divided by 312 is 0 with a remainder of 126.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 126 to get 126.
Append the next digit (7) from the dividend to 126 and continue with: 1267 / 312

Let's proceed to step 4:
1267 divided by 312 is 4 with a remainder of 19.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Subtract 1248 from 1267 to get 19.
Grab the next digit (9) from the dividend, add it to 19, then carry on: 199 / 312

Moving on to step 5:
312 can be fit into 199 0 times, resulting in a remainder of 199.
Record the quotient 0 as the next digit in the result. 
Result so far: 40.0
If we take 0 away from 199, we end up with 199.
Fetch the next digit (0) from the dividend, attach it to 199 and continue: 1990 / 312

Step 6:
If we divide 1990 by 312, we get 6 and a remainder of 118.
Use 6 as the next digit of our solution. 
Result so far: 406.0
If we subtract 1872 from 1990, we get 118.
Include the next digit (0) from the dividend after 118, then repeat: 1180 / 312

Moving on to step 7:
312 can be fit into 1180 3 times, resulting in a remainder of 244.
Write down 3 as next digit of the result. 
Result so far: 4063.0
Subtracting 936 from 1180 leaves us with 244.
Bring next digit (2) of the dividend behind the 244 and repeat the process: 2442 / 312

On to step 8:
The number 312 fits into 2442 7 times, leaving a remainder of 258.
Write down 7 as next digit of the result. 
Result so far: 40637.0
Subtracting 2184 from 2442 leaves us with 258.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2580, and continue the process.

Step 9:
The number 312 fits into 2580 8 times, leaving a remainder of 84.
The next digit of our result is 8. 
Result so far: 40637.8
The remainder is 84 after subtracting 2496 from 2580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Moving on to step 10:
The number 312 fits into 840 2 times, leaving a remainder of 216.
The next digit of our result is 2. 
Result so far: 40637.82
Subtract 624 from 840 to 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.

Let's proceed to step 11:
312 can be fit into 2160 6 times, resulting in a remainder of 288.
Use 6 as the next digit of our solution. 
Result so far: 40637.826
Subtracting 1872 from 2160 leaves us with 288.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

Going ahead to step 12:
When dividing 2880 by 312, we get 9 with a remainder of 72.
The number 9 becomes the next digit in our result. 
Result so far: 40637.8269
Subtract 2808 from 2880 to 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.

Let's proceed to step 13:
312 can be fit into 720 2 times, resulting in a remainder of 96.
The next digit of our result is 2. 
Result so far: 40637.82692
If we subtract 624 from 720, we get 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Let's proceed to step 14:
If we divide 960 by 312, we get 3 and a remainder of 24.
The next digit of our result is 3. 
Result so far: 40637.826923
If we subtract 936 from 960, we 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 15:
When dividing 240 by 312, we get 0 with a remainder of 240.
The next digit of our result is 0. 
Result so far: 40637.826923
The remainder is 240 after subtracting 0 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

On to step 16:
312 can be fit into 2400 7 times, resulting in a remainder of 216.
The next digit of our result is 7. 
Result so far: 40637.82692307
The remainder is 216 after subtracting 2184 from 2400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

Our division results in 40637.82692307 with a remaining 2.16e-07.
