We look at the division of 284320 by 63 
The aim is to understand the frequency of 63 in 284320.

Advancing to step 1:
2 divided by 63 is 0 with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Bring next digit (8) of the dividend behind the 2 and repeat the process: 28 / 63

Advancing to step 2:
28 divided by 63 is 0 with a remainder of 28.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 28, we end up with 28.
Append the next digit (4) from the dividend to 28 and continue with: 284 / 63

On to step 3:
The number 63 fits into 284 4 times, leaving a remainder of 32.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
If we subtract 252 from 284, we get 32.
Grab the next digit (3) from the dividend, add it to 32, then carry on: 323 / 63

On to step 4:
If we divide 323 by 63, we get 5 and a remainder of 8.
Record the quotient 5 as the next digit in the result. 
Result so far: 45.0
The remainder is 8 after subtracting 315 from 323.
Take the next digit (2) from the dividend and append it to 8, then repeat: 82 / 63

Step 5:
When dividing 82 by 63, we get 1 with a remainder of 19.
Put 1 as the next digit of the answer. 
Result so far: 451.0
Deduct 63 from 82 and we're left with 19.
Append the next digit (0) from the dividend to 19 and continue with: 190 / 63

Moving on to step 6:
63 goes into 190 3 times with a remainder of 1.
The number 3 becomes the next digit in our result. 
Result so far: 4513.0
If we subtract 189 from 190, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 7:
63 can be fit into 10 0 times, resulting in a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 4513.0
If we take 0 away from 10, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 8:
When dividing 100 by 63, we get 1 with a remainder of 37.
Write down 1 as next digit of the result. 
Result so far: 4513.01
If we subtract 63 from 100, we get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Going ahead to step 9:
The number 63 fits into 370 5 times, leaving a remainder of 55.
Write down 5 as next digit of the result. 
Result so far: 4513.015
Subtract 315 from 370 to get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Advancing to step 10:
550 divided by 63 is 8 with a remainder of 46.
Write down 8 as next digit of the result. 
Result so far: 4513.0158
Deduct 504 from 550 and we're left with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

On to step 11:
The number 63 fits into 460 7 times, leaving a remainder of 19.
Write down 7 as next digit of the result. 
Result so far: 4513.01587
If we subtract 441 from 460, we get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Let's proceed to step 12:
If we divide 190 by 63, we get 3 and a remainder of 1.
Record the quotient 3 as the next digit in the result. 
Result so far: 4513.015873
Subtracting 189 from 190 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 13:
63 goes into 10 0 times with a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 4513.015873
If we take 0 away from 10, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 14:
If we divide 100 by 63, we get 1 and a remainder of 37.
Put 1 as the next digit of the answer. 
Result so far: 4513.01587301
If we subtract 63 from 100, we get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

The final outcome is 4513.01587301, with a leftover of 3.7e-08.
