575604 ÷ 63 
The aim is to understand the frequency of 63 in 575604.

Moving on to step 1:
63 goes into 5 0 times with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Include the next digit (7) from the dividend after 5, then repeat: 57 / 63

Advancing to step 2:
63 can be fit into 57 0 times, resulting in a remainder of 57.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 57 after subtracting 0 from 57.
Fetch the next digit (5) from the dividend, attach it to 57 and continue: 575 / 63

Let's proceed to step 3:
If we divide 575 by 63, we get 9 and a remainder of 8.
Use 9 as the next digit of our solution. 
Result so far: 9.0
Subtract 567 from 575 to get 8.
Take the next digit (6) from the dividend and append it to 8, then repeat: 86 / 63

Advancing to step 4:
63 goes into 86 1 times with a remainder of 23.
Record the quotient 1 as the next digit in the result. 
Result so far: 91.0
Subtracting 63 from 86 leaves us with 23.
Fetch the next digit (0) from the dividend, attach it to 23 and continue: 230 / 63

Advancing to step 5:
If we divide 230 by 63, we get 3 and a remainder of 41.
Use 3 as the next digit of our solution. 
Result so far: 913.0
Deduct 189 from 230 and we're left with 41.
Grab the next digit (4) from the dividend, add it to 41, then carry on: 414 / 63

On to step 6:
When dividing 414 by 63, we get 6 with a remainder of 36.
The next digit of our result is 6. 
Result so far: 9136.0
If we subtract 378 from 414, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 7:
63 can be fit into 360 5 times, resulting in a remainder of 45.
Put 5 as the next digit of the answer. 
Result so far: 9136.5
Subtract 315 from 360 to get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Advancing to step 8:
When dividing 450 by 63, we get 7 with a remainder of 9.
The next digit of our result is 7. 
Result so far: 9136.57
Subtract 441 from 450 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Going ahead to step 9:
63 goes into 90 1 times with a remainder of 27.
Use 1 as the next digit of our solution. 
Result so far: 9136.571
Subtract 63 from 90 to get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Moving on to step 10:
When dividing 270 by 63, we get 4 with a remainder of 18.
The next digit of our result is 4. 
Result so far: 9136.5714
Subtracting 252 from 270 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 11:
63 goes into 180 2 times with a remainder of 54.
The number 2 becomes the next digit in our result. 
Result so far: 9136.57142
Subtract 126 from 180 to get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Let's proceed to step 12:
When dividing 540 by 63, we get 8 with a remainder of 36.
The number 8 becomes the next digit in our result. 
Result so far: 9136.571428
Subtract 504 from 540 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Let's proceed to step 13:
360 divided by 63 is 5 with a remainder of 45.
The next digit of our result is 5. 
Result so far: 9136.5714285
If we subtract 315 from 360, we get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Let's proceed to step 14:
450 divided by 63 is 7 with a remainder of 9.
The next digit of our result is 7. 
Result so far: 9136.57142857
Subtract 441 from 450 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

After the division, we end up with 9136.57142857 and a remainder of 9e-09.
