Let's divide 631511 by 63
The aim is to understand the frequency of 63 in 631511.

Going ahead to step 1:
63 can be fit into 6 0 times, resulting in 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.
Bring next digit (3) of the dividend behind the 6 and repeat the process: 63 / 63

Going ahead to step 2:
When dividing 63 by 63, we get 1 with a remainder of 0.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 0 after subtracting 63 from 63.
Bring next digit (1) of the dividend behind the 0 and repeat the process: 1 / 63

Moving on to step 3:
If we divide 1 by 63, we get 0 and a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
If we subtract 0 from 1, we get 1.
Grab the next digit (5) from the dividend, add it to 1, then carry on: 15 / 63

Step 4:
If we divide 15 by 63, we get 0 and a remainder of 15.
The next digit of our result is 0. 
Result so far: 100.0
Deduct 0 from 15 and we're left with 15.
Bring next digit (1) of the dividend behind the 15 and repeat the process: 151 / 63

Step 5:
The number 63 fits into 151 2 times, leaving a remainder of 25.
Use 2 as the next digit of our solution. 
Result so far: 1002.0
If we subtract 126 from 151, we get 25.
Fetch the next digit (1) from the dividend, attach it to 25 and continue: 251 / 63

Moving on to step 6:
If we divide 251 by 63, we get 3 and a remainder of 62.
Write down 3 as next digit of the result. 
Result so far: 10023.0
Subtracting 189 from 251 leaves us with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Going ahead to step 7:
620 divided by 63 is 9 with a remainder of 53.
Write down 9 as next digit of the result. 
Result so far: 10023.9
The remainder is 53 after subtracting 567 from 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Moving on to step 8:
63 can be fit into 530 8 times, resulting in a remainder of 26.
The next digit of our result is 8. 
Result so far: 10023.98
The remainder is 26 after subtracting 504 from 530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Let's proceed to step 9:
The number 63 fits into 260 4 times, leaving a remainder of 8.
The number 4 becomes the next digit in our result. 
Result so far: 10023.984
Deduct 252 from 260 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 10:
When dividing 80 by 63, we get 1 with a remainder of 17.
Use 1 as the next digit of our solution. 
Result so far: 10023.9841
The remainder is 17 after subtracting 63 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Let's proceed to step 11:
The number 63 fits into 170 2 times, leaving a remainder of 44.
Put 2 as the next digit of the answer. 
Result so far: 10023.98412
If we take 126 away from 170, we end up with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Going ahead to step 12:
When dividing 440 by 63, we get 6 with a remainder of 62.
Put 6 as the next digit of the answer. 
Result so far: 10023.984126
If we take 378 away from 440, we end up with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

On to step 13:
63 goes into 620 9 times with a remainder of 53.
The next digit of our result is 9. 
Result so far: 10023.9841269
Deduct 567 from 620 and we're left with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Moving on to step 14:
530 divided by 63 is 8 with a remainder of 26.
Record the quotient 8 as the next digit in the result. 
Result so far: 10023.98412698
Subtract 504 from 530 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

The final result is 10023.98412698 with a remainder of 2.6e-08.
