745312 ÷ 63 
The aim is to understand the frequency of 63 in 745312.

Going ahead to step 1:
If we divide 7 by 63, we get 0 and a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Include the next digit (4) from the dividend after 7, then repeat: 74 / 63

Going ahead to step 2:
74 divided by 63 is 1 with a remainder of 11.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 63 away from 74, we end up with 11.
Include the next digit (5) from the dividend after 11, then repeat: 115 / 63

Moving on to step 3:
If we divide 115 by 63, we get 1 and a remainder of 52.
The next digit of our result is 1. 
Result so far: 11.0
If we take 63 away from 115, we end up with 52.
Append the next digit (3) from the dividend to 52 and continue with: 523 / 63

Moving on to step 4:
If we divide 523 by 63, we get 8 and a remainder of 19.
Write down 8 as next digit of the result. 
Result so far: 118.0
The remainder is 19 after subtracting 504 from 523.
Fetch the next digit (1) from the dividend, attach it to 19 and continue: 191 / 63

Moving on to step 5:
63 goes into 191 3 times with a remainder of 2.
The number 3 becomes the next digit in our result. 
Result so far: 1183.0
If we subtract 189 from 191, we get 2.
Fetch the next digit (2) from the dividend, attach it to 2 and continue: 22 / 63

Step 6:
63 goes into 22 0 times with a remainder of 22.
The number 0 becomes the next digit in our result. 
Result so far: 11830.0
Subtracting 0 from 22 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 7:
63 goes into 220 3 times with a remainder of 31.
The number 3 becomes the next digit in our result. 
Result so far: 11830.3
If we take 189 away from 220, we end up with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Moving on to step 8:
63 can be fit into 310 4 times, resulting in a remainder of 58.
Record the quotient 4 as the next digit in the result. 
Result so far: 11830.34
Deduct 252 from 310 and we're left with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Let's proceed to step 9:
580 divided by 63 is 9 with a remainder of 13.
The number 9 becomes the next digit in our result. 
Result so far: 11830.349
The remainder is 13 after subtracting 567 from 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Going ahead to step 10:
The number 63 fits into 130 2 times, leaving a remainder of 4.
Put 2 as the next digit of the answer. 
Result so far: 11830.3492
Subtracting 126 from 130 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 11:
The number 63 fits into 40 0 times, leaving a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 11830.3492
If we subtract 0 from 40, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 12:
63 can be fit into 400 6 times, resulting in a remainder of 22.
Use 6 as the next digit of our solution. 
Result so far: 11830.349206
Deduct 378 from 400 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Going ahead to step 13:
63 can be fit into 220 3 times, resulting in a remainder of 31.
The number 3 becomes the next digit in our result. 
Result so far: 11830.3492063
If we take 189 away from 220, we end up with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Moving on to step 14:
The number 63 fits into 310 4 times, leaving a remainder of 58.
Record the quotient 4 as the next digit in the result. 
Result so far: 11830.34920634
Subtract 252 from 310 to get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

After the division, we end up with 11830.34920634 and a remainder of 5.8e-08.
