We're dividing 607581 by 63 
The aim is to understand the frequency of 63 in 607581.

Advancing to step 1:
When dividing 6 by 63, we get 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Append the next digit (0) from the dividend to 6 and continue with: 60 / 63

On to step 2:
If we divide 60 by 63, we get 0 and a remainder of 60.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 60, we end up with 60.
Grab the next digit (7) from the dividend, add it to 60, then carry on: 607 / 63

On to step 3:
63 can be fit into 607 9 times, resulting in a remainder of 40.
Use 9 as the next digit of our solution. 
Result so far: 9.0
If we subtract 567 from 607, we get 40.
Bring next digit (5) of the dividend behind the 40 and repeat the process: 405 / 63

Advancing to step 4:
63 can be fit into 405 6 times, resulting in a remainder of 27.
Record the quotient 6 as the next digit in the result. 
Result so far: 96.0
The remainder is 27 after subtracting 378 from 405.
Include the next digit (8) from the dividend after 27, then repeat: 278 / 63

Moving on to step 5:
63 goes into 278 4 times with a remainder of 26.
Put 4 as the next digit of the answer. 
Result so far: 964.0
If we take 252 away from 278, we end up with 26.
Include the next digit (1) from the dividend after 26, then repeat: 261 / 63

Let's proceed to step 6:
63 goes into 261 4 times with a remainder of 9.
Use 4 as the next digit of our solution. 
Result so far: 9644.0
Subtracting 252 from 261 leaves us with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Advancing to step 7:
The number 63 fits into 90 1 times, leaving a remainder of 27.
The number 1 becomes the next digit in our result. 
Result so far: 9644.1
If we take 63 away from 90, we end up with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Step 8:
63 can be fit into 270 4 times, resulting in a remainder of 18.
The number 4 becomes the next digit in our result. 
Result so far: 9644.14
If we take 252 away from 270, we end up 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.

Step 9:
When dividing 180 by 63, we get 2 with a remainder of 54.
Use 2 as the next digit of our solution. 
Result so far: 9644.142
The remainder is 54 after subtracting 126 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

On to step 10:
63 can be fit into 540 8 times, resulting in a remainder of 36.
Write down 8 as next digit of the result. 
Result so far: 9644.1428
If we take 504 away from 540, we end up with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 11:
360 divided by 63 is 5 with a remainder of 45.
The next digit of our result is 5. 
Result so far: 9644.14285
Subtracting 315 from 360 leaves us with 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 12:
450 divided by 63 is 7 with a remainder of 9.
The next digit of our result is 7. 
Result so far: 9644.142857
Deduct 441 from 450 and we're left with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 13:
When dividing 90 by 63, we get 1 with a remainder of 27.
The number 1 becomes the next digit in our result. 
Result so far: 9644.1428571
If we subtract 63 from 90, we 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.

Advancing to step 14:
If we divide 270 by 63, we get 4 and a remainder of 18.
The number 4 becomes the next digit in our result. 
Result so far: 9644.14285714
Subtract 252 from 270 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

After the division, we end up with 9644.14285714 and a remainder of 1.8e-08.
