64787942 divided by 312 
The aim is to understand the frequency of 312 in 64787942.

Advancing to step 1:
When dividing 6 by 312, we get 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Fetch the next digit (4) from the dividend, attach it to 6 and continue: 64 / 312

Advancing to step 2:
When dividing 64 by 312, we get 0 with a remainder of 64.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 64, we end up with 64.
Take the next digit (7) from the dividend and append it to 64, then repeat: 647 / 312

Let's proceed to step 3:
647 divided by 312 is 2 with a remainder of 23.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtracting 624 from 647 leaves us with 23.
Bring next digit (8) of the dividend behind the 23 and repeat the process: 238 / 312

On to step 4:
238 divided by 312 is 0 with a remainder of 238.
The next digit of our result is 0. 
Result so far: 20.0
If we take 0 away from 238, we end up with 238.
Include the next digit (7) from the dividend after 238, then repeat: 2387 / 312

Advancing to step 5:
When dividing 2387 by 312, we get 7 with a remainder of 203.
Put 7 as the next digit of the answer. 
Result so far: 207.0
If we take 2184 away from 2387, we end up with 203.
Append the next digit (9) from the dividend to 203 and continue with: 2039 / 312

Going ahead to step 6:
The number 312 fits into 2039 6 times, leaving a remainder of 167.
The number 6 becomes the next digit in our result. 
Result so far: 2076.0
If we subtract 1872 from 2039, we get 167.
Include the next digit (4) from the dividend after 167, then repeat: 1674 / 312

Step 7:
When dividing 1674 by 312, we get 5 with a remainder of 114.
Use 5 as the next digit of our solution. 
Result so far: 20765.0
Deduct 1560 from 1674 and we're left with 114.
Append the next digit (2) from the dividend to 114 and continue with: 1142 / 312

Step 8:
The number 312 fits into 1142 3 times, leaving a remainder of 206.
Use 3 as the next digit of our solution. 
Result so far: 207653.0
Deduct 936 from 1142 and we're left with 206.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2060, and continue the process.

Step 9:
If we divide 2060 by 312, we get 6 and a remainder of 188.
The next digit of our result is 6. 
Result so far: 207653.6
If we take 1872 away from 2060, we end up with 188.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1880, and continue the process.

Going ahead to step 10:
312 goes into 1880 6 times with a remainder of 8.
Use 6 as the next digit of our solution. 
Result so far: 207653.66
If we take 1872 away from 1880, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

In conclusion, the division gives 207653.66 with a balance of 0.008.
