We look at the division of 625224 by 63 
The aim is to understand the frequency of 63 in 625224.

Going ahead to step 1:
When dividing 6 by 63, we get 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Fetch the next digit (2) from the dividend, attach it to 6 and continue: 62 / 63

Advancing to step 2:
The number 63 fits into 62 0 times, leaving a remainder of 62.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 62 and we're left with 62.
Grab the next digit (5) from the dividend, add it to 62, then carry on: 625 / 63

Step 3:
625 divided by 63 is 9 with a remainder of 58.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
Deduct 567 from 625 and we're left with 58.
Append the next digit (2) from the dividend to 58 and continue with: 582 / 63

Step 4:
582 divided by 63 is 9 with a remainder of 15.
Use 9 as the next digit of our solution. 
Result so far: 99.0
Deduct 567 from 582 and we're left with 15.
Take the next digit (2) from the dividend and append it to 15, then repeat: 152 / 63

Step 5:
152 divided by 63 is 2 with a remainder of 26.
The next digit of our result is 2. 
Result so far: 992.0
Deduct 126 from 152 and we're left with 26.
Bring next digit (4) of the dividend behind the 26 and repeat the process: 264 / 63

Step 6:
If we divide 264 by 63, we get 4 and a remainder of 12.
The next digit of our result is 4. 
Result so far: 9924.0
Deduct 252 from 264 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 7:
If we divide 120 by 63, we get 1 and a remainder of 57.
Record the quotient 1 as the next digit in the result. 
Result so far: 9924.1
Deduct 63 from 120 and we're left with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Let's proceed to step 8:
The number 63 fits into 570 9 times, leaving a remainder of 3.
Write down 9 as next digit of the result. 
Result so far: 9924.19
Subtract 567 from 570 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 9:
30 divided by 63 is 0 with a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 9924.19
Subtract 0 from 30 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 10:
When dividing 300 by 63, we get 4 with a remainder of 48.
Put 4 as the next digit of the answer. 
Result so far: 9924.1904
Deduct 252 from 300 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Step 11:
If we divide 480 by 63, we get 7 and a remainder of 39.
Use 7 as the next digit of our solution. 
Result so far: 9924.19047
The remainder is 39 after subtracting 441 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Let's proceed to step 12:
390 divided by 63 is 6 with a remainder of 12.
The next digit of our result is 6. 
Result so far: 9924.190476
Subtract 378 from 390 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 13:
When dividing 120 by 63, we get 1 with a remainder of 57.
Put 1 as the next digit of the answer. 
Result so far: 9924.1904761
If we subtract 63 from 120, we get 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Going ahead to step 14:
If we divide 570 by 63, we get 9 and a remainder of 3.
Record the quotient 9 as the next digit in the result. 
Result so far: 9924.19047619
If we take 567 away from 570, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

After the division, we end up with 9924.19047619 and a remainder of 3e-09.
