We look at the division of 839569 by 63 
The aim is to understand the frequency of 63 in 839569.

Let's proceed to step 1:
63 can be fit into 8 0 times, resulting in a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Take the next digit (3) from the dividend and append it to 8, then repeat: 83 / 63

Let's proceed to step 2:
83 divided by 63 is 1 with a remainder of 20.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 63 from 83 to get 20.
Take the next digit (9) from the dividend and append it to 20, then repeat: 209 / 63

Step 3:
When dividing 209 by 63, we get 3 with a remainder of 20.
The next digit of our result is 3. 
Result so far: 13.0
Subtract 189 from 209 to get 20.
Append the next digit (5) from the dividend to 20 and continue with: 205 / 63

Moving on to step 4:
63 goes into 205 3 times with a remainder of 16.
Record the quotient 3 as the next digit in the result. 
Result so far: 133.0
The remainder is 16 after subtracting 189 from 205.
Grab the next digit (6) from the dividend, add it to 16, then carry on: 166 / 63

Let's proceed to step 5:
63 can be fit into 166 2 times, resulting in a remainder of 40.
Write down 2 as next digit of the result. 
Result so far: 1332.0
Subtract 126 from 166 to get 40.
Append the next digit (9) from the dividend to 40 and continue with: 409 / 63

Let's proceed to step 6:
When dividing 409 by 63, we get 6 with a remainder of 31.
Record the quotient 6 as the next digit in the result. 
Result so far: 13326.0
The remainder is 31 after subtracting 378 from 409.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Let's proceed to step 7:
If we divide 310 by 63, we get 4 and a remainder of 58.
Put 4 as the next digit of the answer. 
Result so far: 13326.4
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.

Advancing to step 8:
The number 63 fits into 580 9 times, leaving a remainder of 13.
Use 9 as the next digit of our solution. 
Result so far: 13326.49
Subtract 567 from 580 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Step 9:
63 can be fit into 130 2 times, resulting in a remainder of 4.
The number 2 becomes the next digit in our result. 
Result so far: 13326.492
Deduct 126 from 130 and we're left 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.

Going ahead to step 10:
63 goes into 40 0 times with a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 13326.492
Deduct 0 from 40 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 11:
63 goes into 400 6 times with a remainder of 22.
Record the quotient 6 as the next digit in the result. 
Result so far: 13326.49206
The remainder is 22 after subtracting 378 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 12:
63 goes into 220 3 times with a remainder of 31.
Put 3 as the next digit of the answer. 
Result so far: 13326.492063
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.

Going ahead to step 13:
When dividing 310 by 63, we get 4 with a remainder of 58.
Record the quotient 4 as the next digit in the result. 
Result so far: 13326.4920634
Subtracting 252 from 310 leaves us 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.

Moving on to step 14:
When dividing 580 by 63, we get 9 with a remainder of 13.
Put 9 as the next digit of the answer. 
Result so far: 13326.49206349
If we subtract 567 from 580, we get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Our division results in 13326.49206349 with a remaining 1.3e-08.
