We look at the division of 742502 by 63 
The aim is to understand the frequency of 63 in 742502.

Step 1:
63 goes into 7 0 times with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Grab the next digit (4) from the dividend, add it to 7, then carry on: 74 / 63

Going ahead to step 2:
63 goes into 74 1 times with a remainder of 11.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 63 from 74, we get 11.
Grab the next digit (2) from the dividend, add it to 11, then carry on: 112 / 63

On to step 3:
The number 63 fits into 112 1 times, leaving a remainder of 49.
The next digit of our result is 1. 
Result so far: 11.0
If we subtract 63 from 112, we get 49.
Grab the next digit (5) from the dividend, add it to 49, then carry on: 495 / 63

Going ahead to step 4:
The number 63 fits into 495 7 times, leaving a remainder of 54.
Record the quotient 7 as the next digit in the result. 
Result so far: 117.0
If we take 441 away from 495, we end up with 54.
Bring next digit (0) of the dividend behind the 54 and repeat the process: 540 / 63

Step 5:
63 goes into 540 8 times with a remainder of 36.
The next digit of our result is 8. 
Result so far: 1178.0
Subtracting 504 from 540 leaves us with 36.
Take the next digit (2) from the dividend and append it to 36, then repeat: 362 / 63

Going ahead to step 6:
63 goes into 362 5 times with a remainder of 47.
Use 5 as the next digit of our solution. 
Result so far: 11785.0
Deduct 315 from 362 and we're left with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

On to step 7:
If we divide 470 by 63, we get 7 and a remainder of 29.
Write down 7 as next digit of the result. 
Result so far: 11785.7
Subtracting 441 from 470 leaves us with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Going ahead to step 8:
If we divide 290 by 63, we get 4 and a remainder of 38.
Put 4 as the next digit of the answer. 
Result so far: 11785.74
If we take 252 away from 290, we end up with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Let's proceed to step 9:
63 can be fit into 380 6 times, resulting in a remainder of 2.
Write down 6 as next digit of the result. 
Result so far: 11785.746
If we take 378 away from 380, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 10:
If we divide 20 by 63, we get 0 and a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 11785.746
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 11:
When dividing 200 by 63, we get 3 with a remainder of 11.
Put 3 as the next digit of the answer. 
Result so far: 11785.74603
Subtracting 189 from 200 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

On to step 12:
110 divided by 63 is 1 with a remainder of 47.
Use 1 as the next digit of our solution. 
Result so far: 11785.746031
If we take 63 away from 110, we end up with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Going ahead to step 13:
If we divide 470 by 63, we get 7 and a remainder of 29.
The next digit of our result is 7. 
Result so far: 11785.7460317
The remainder is 29 after subtracting 441 from 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Advancing to step 14:
63 goes into 290 4 times with a remainder of 38.
Put 4 as the next digit of the answer. 
Result so far: 11785.74603174
Subtracting 252 from 290 leaves us with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

The final result is 11785.74603174 with a remainder of 3.8e-08.
