312137 ÷ 63 
The aim is to understand the frequency of 63 in 312137.

Going ahead to step 1:
63 can be fit into 3 0 times, resulting in a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Bring next digit (1) of the dividend behind the 3 and repeat the process: 31 / 63

Moving on to step 2:
63 can be fit into 31 0 times, resulting in a remainder of 31.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 31 and we're left with 31.
Bring next digit (2) of the dividend behind the 31 and repeat the process: 312 / 63

On to step 3:
63 goes into 312 4 times with a remainder of 60.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
If we subtract 252 from 312, we get 60.
Include the next digit (1) from the dividend after 60, then repeat: 601 / 63

Let's proceed to step 4:
63 can be fit into 601 9 times, resulting in a remainder of 34.
The next digit of our result is 9. 
Result so far: 49.0
If we take 567 away from 601, we end up with 34.
Append the next digit (3) from the dividend to 34 and continue with: 343 / 63

Advancing to step 5:
When dividing 343 by 63, we get 5 with a remainder of 28.
Use 5 as the next digit of our solution. 
Result so far: 495.0
Subtract 315 from 343 to get 28.
Take the next digit (7) from the dividend and append it to 28, then repeat: 287 / 63

Moving on to step 6:
287 divided by 63 is 4 with a remainder of 35.
Use 4 as the next digit of our solution. 
Result so far: 4954.0
If we take 252 away from 287, we end up with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Let's proceed to step 7:
63 can be fit into 350 5 times, resulting in a remainder of 35.
The number 5 becomes the next digit in our result. 
Result so far: 4954.5
Subtracting 315 from 350 leaves us with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Advancing to step 8:
350 divided by 63 is 5 with a remainder of 35.
The next digit of our result is 5. 
Result so far: 4954.55
If we subtract 315 from 350, we get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

The final result is 4954.55 with a remainder of 0.035.
