We divide 642657 by 63
The aim is to understand the frequency of 63 in 642657.

Moving on to step 1:
63 goes into 6 0 times with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Take the next digit (4) from the dividend and append it to 6, then repeat: 64 / 63

On to step 2:
The number 63 fits into 64 1 times, leaving a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 63 from 64, we get 1.
Grab the next digit (2) from the dividend, add it to 1, then carry on: 12 / 63

Moving on to step 3:
63 can be fit into 12 0 times, resulting in a remainder of 12.
The next digit of our result is 0. 
Result so far: 10.0
Deduct 0 from 12 and we're left with 12.
Fetch the next digit (6) from the dividend, attach it to 12 and continue: 126 / 63

On to step 4:
The number 63 fits into 126 2 times, leaving a remainder of 0.
The number 2 becomes the next digit in our result. 
Result so far: 102.0
The remainder is 0 after subtracting 126 from 126.
Bring next digit (5) of the dividend behind the 0 and repeat the process: 5 / 63

Going ahead to step 5:
5 divided by 63 is 0 with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 1020.0
Subtract 0 from 5 to get 5.
Take the next digit (7) from the dividend and append it to 5, then repeat: 57 / 63

Step 6:
If we divide 57 by 63, we get 0 and a remainder of 57.
The next digit of our result is 0. 
Result so far: 10200.0
Deduct 0 from 57 and we're left with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Let's proceed to step 7:
When dividing 570 by 63, we get 9 with a remainder of 3.
The next digit of our result is 9. 
Result so far: 10200.9
Subtract 567 from 570 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 8:
63 goes into 30 0 times with a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 10200.9
If we take 0 away from 30, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 9:
The number 63 fits into 300 4 times, leaving a remainder of 48.
Use 4 as the next digit of our solution. 
Result so far: 10200.904
Subtracting 252 from 300 leaves us with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Going ahead to step 10:
The number 63 fits into 480 7 times, leaving a remainder of 39.
Record the quotient 7 as the next digit in the result. 
Result so far: 10200.9047
The remainder is 39 after subtracting 441 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Going ahead to step 11:
The number 63 fits into 390 6 times, leaving a remainder of 12.
The next digit of our result is 6. 
Result so far: 10200.90476
Subtracting 378 from 390 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 12:
When dividing 120 by 63, we get 1 with a remainder of 57.
Use 1 as the next digit of our solution. 
Result so far: 10200.904761
If we subtract 63 from 120, we get 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

On to step 13:
570 divided by 63 is 9 with a remainder of 3.
Record the quotient 9 as the next digit in the result. 
Result so far: 10200.9047619
Subtract 567 from 570 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 14:
If we divide 30 by 63, we get 0 and a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 10200.9047619
If we subtract 0 from 30, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

The final outcome is 10200.9047619, with a leftover of 3e-08.
