13759772 divided by 312 
The aim is to understand the frequency of 312 in 13759772.

On to step 1:
The number 312 fits into 1 0 times, leaving a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Grab the next digit (3) from the dividend, add it to 1, then carry on: 13 / 312

Let's proceed to step 2:
312 can be fit into 13 0 times, resulting in a remainder of 13.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 13 leaves us with 13.
Take the next digit (7) from the dividend and append it to 13, then repeat: 137 / 312

Let's proceed to step 3:
312 goes into 137 0 times with a remainder of 137.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 137 leaves us with 137.
Bring next digit (5) of the dividend behind the 137 and repeat the process: 1375 / 312

Let's proceed to step 4:
If we divide 1375 by 312, we get 4 and a remainder of 127.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Deduct 1248 from 1375 and we're left with 127.
Include the next digit (9) from the dividend after 127, then repeat: 1279 / 312

Step 5:
312 can be fit into 1279 4 times, resulting in a remainder of 31.
The number 4 becomes the next digit in our result. 
Result so far: 44.0
If we subtract 1248 from 1279, we get 31.
Fetch the next digit (7) from the dividend, attach it to 31 and continue: 317 / 312

Going ahead to step 6:
312 can be fit into 317 1 times, resulting in a remainder of 5.
The next digit of our result is 1. 
Result so far: 441.0
The remainder is 5 after subtracting 312 from 317.
Take the next digit (7) from the dividend and append it to 5, then repeat: 57 / 312

Let's proceed to step 7:
If we divide 57 by 312, we get 0 and a remainder of 57.
The next digit of our result is 0. 
Result so far: 4410.0
The remainder is 57 after subtracting 0 from 57.
Take the next digit (2) from the dividend and append it to 57, then repeat: 572 / 312

On to step 8:
The number 312 fits into 572 1 times, leaving a remainder of 260.
The number 1 becomes the next digit in our result. 
Result so far: 44101.0
Subtracting 312 from 572 leaves us with 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Going ahead to step 9:
312 goes into 2600 8 times with a remainder of 104.
Put 8 as the next digit of the answer. 
Result so far: 44101.8
Subtracting 2496 from 2600 leaves us with 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

On to step 10:
When dividing 1040 by 312, we get 3 with a remainder of 104.
Use 3 as the next digit of our solution. 
Result so far: 44101.83
Subtracting 936 from 1040 leaves us with 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Let's proceed to step 11:
When dividing 1040 by 312, we get 3 with a remainder of 104.
The number 3 becomes the next digit in our result. 
Result so far: 44101.833
If we take 936 away from 1040, we end up with 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

After the division, we end up with 44101.833 and a remainder of 0.0104.
