We look at the division of 39346645 by 312 
The aim is to understand the frequency of 312 in 39346645.

Moving on to step 1:
312 can be fit into 3 0 times, resulting in a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Bring next digit (9) of the dividend behind the 3 and repeat the process: 39 / 312

Moving on to step 2:
39 divided by 312 is 0 with a remainder of 39.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 39 to get 39.
Fetch the next digit (3) from the dividend, attach it to 39 and continue: 393 / 312

On to step 3:
312 goes into 393 1 times with a remainder of 81.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 312 from 393, we get 81.
Grab the next digit (4) from the dividend, add it to 81, then carry on: 814 / 312

Let's proceed to step 4:
If we divide 814 by 312, we get 2 and a remainder of 190.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
Deduct 624 from 814 and we're left with 190.
Append the next digit (6) from the dividend to 190 and continue with: 1906 / 312

Advancing to step 5:
If we divide 1906 by 312, we get 6 and a remainder of 34.
The number 6 becomes the next digit in our result. 
Result so far: 126.0
Subtracting 1872 from 1906 leaves us with 34.
Append the next digit (6) from the dividend to 34 and continue with: 346 / 312

Step 6:
346 divided by 312 is 1 with a remainder of 34.
Put 1 as the next digit of the answer. 
Result so far: 1261.0
If we take 312 away from 346, we end up with 34.
Take the next digit (4) from the dividend and append it to 34, then repeat: 344 / 312

Step 7:
When dividing 344 by 312, we get 1 with a remainder of 32.
Record the quotient 1 as the next digit in the result. 
Result so far: 12611.0
If we take 312 away from 344, we end up with 32.
Bring next digit (5) of the dividend behind the 32 and repeat the process: 325 / 312

Let's proceed to step 8:
312 goes into 325 1 times with a remainder of 13.
Record the quotient 1 as the next digit in the result. 
Result so far: 126111.0
Deduct 312 from 325 and we're left with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Step 9:
When dividing 130 by 312, we get 0 with a remainder of 130.
Put 0 as the next digit of the answer. 
Result so far: 126111.0
Deduct 0 from 130 and we're left with 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Going ahead to step 10:
1300 divided by 312 is 4 with a remainder of 52.
Record the quotient 4 as the next digit in the result. 
Result so far: 126111.04
If we subtract 1248 from 1300, we get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Going ahead to step 11:
If we divide 520 by 312, we get 1 and a remainder of 208.
The number 1 becomes the next digit in our result. 
Result so far: 126111.041
Subtracting 312 from 520 leaves us with 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

Let's proceed to step 12:
The number 312 fits into 2080 6 times, leaving a remainder of 208.
Record the quotient 6 as the next digit in the result. 
Result so far: 126111.0416
Deduct 1872 from 2080 and we're left with 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

Moving on to step 13:
The number 312 fits into 2080 6 times, leaving a remainder of 208.
Put 6 as the next digit of the answer. 
Result so far: 126111.04166
Deduct 1872 from 2080 and we're left with 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

Our division results in 126111.04166 with a remaining 0.000208.
