Let's divide 620508 by 63
The aim is to understand the frequency of 63 in 620508.

On to step 1:
If we divide 6 by 63, we get 0 and a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Append the next digit (2) from the dividend to 6 and continue with: 62 / 63

Advancing to step 2:
62 divided by 63 is 0 with a remainder of 62.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 62 leaves us with 62.
Take the next digit (0) from the dividend and append it to 62, then repeat: 620 / 63

Let's proceed to step 3:
When dividing 620 by 63, we get 9 with a remainder of 53.
Write down 9 as next digit of the result. 
Result so far: 9.0
Subtract 567 from 620 to get 53.
Append the next digit (5) from the dividend to 53 and continue with: 535 / 63

Advancing to step 4:
If we divide 535 by 63, we get 8 and a remainder of 31.
Write down 8 as next digit of the result. 
Result so far: 98.0
If we subtract 504 from 535, we get 31.
Take the next digit (0) from the dividend and append it to 31, then repeat: 310 / 63

Moving on to step 5:
310 divided by 63 is 4 with a remainder of 58.
Record the quotient 4 as the next digit in the result. 
Result so far: 984.0
If we take 252 away from 310, we end up with 58.
Take the next digit (8) from the dividend and append it to 58, then repeat: 588 / 63

On to step 6:
63 goes into 588 9 times with a remainder of 21.
Record the quotient 9 as the next digit in the result. 
Result so far: 9849.0
Deduct 567 from 588 and we're left with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Advancing to step 7:
63 goes into 210 3 times with a remainder of 21.
Use 3 as the next digit of our solution. 
Result so far: 9849.3
Subtracting 189 from 210 leaves us with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Advancing to step 8:
The number 63 fits into 210 3 times, leaving a remainder of 21.
Put 3 as the next digit of the answer. 
Result so far: 9849.33
If we subtract 189 from 210, we get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Our division results in 9849.33 with a remaining 0.021.
