We're dividing 125889 by 63 
The aim is to understand the frequency of 63 in 125889.

Going ahead to step 1:
63 goes into 1 0 times with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 63

On to step 2:
When dividing 12 by 63, we get 0 with a remainder of 12.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 12, we end up with 12.
Append the next digit (5) from the dividend to 12 and continue with: 125 / 63

Step 3:
The number 63 fits into 125 1 times, leaving a remainder of 62.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 63 from 125 and we're left with 62.
Take the next digit (8) from the dividend and append it to 62, then repeat: 628 / 63

Let's proceed to step 4:
The number 63 fits into 628 9 times, leaving a remainder of 61.
The number 9 becomes the next digit in our result. 
Result so far: 19.0
Deduct 567 from 628 and we're left with 61.
Fetch the next digit (8) from the dividend, attach it to 61 and continue: 618 / 63

Moving on to step 5:
When dividing 618 by 63, we get 9 with a remainder of 51.
The next digit of our result is 9. 
Result so far: 199.0
Subtracting 567 from 618 leaves us with 51.
Fetch the next digit (9) from the dividend, attach it to 51 and continue: 519 / 63

Moving on to step 6:
The number 63 fits into 519 8 times, leaving a remainder of 15.
Use 8 as the next digit of our solution. 
Result so far: 1998.0
If we take 504 away from 519, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 7:
The number 63 fits into 150 2 times, leaving a remainder of 24.
Record the quotient 2 as the next digit in the result. 
Result so far: 1998.2
If we take 126 away from 150, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 8:
If we divide 240 by 63, we get 3 and a remainder of 51.
Put 3 as the next digit of the answer. 
Result so far: 1998.23
If we subtract 189 from 240, we get 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Going ahead to step 9:
When dividing 510 by 63, we get 8 with a remainder of 6.
The number 8 becomes the next digit in our result. 
Result so far: 1998.238
Subtracting 504 from 510 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 10:
The number 63 fits into 60 0 times, leaving a remainder of 60.
Put 0 as the next digit of the answer. 
Result so far: 1998.238
The remainder is 60 after subtracting 0 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 11:
When dividing 600 by 63, we get 9 with a remainder of 33.
Write down 9 as next digit of the result. 
Result so far: 1998.23809
Subtracting 567 from 600 leaves us with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Step 12:
330 divided by 63 is 5 with a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 1998.238095
Deduct 315 from 330 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 13:
63 goes into 150 2 times with a remainder of 24.
The number 2 becomes the next digit in our result. 
Result so far: 1998.2380952
The remainder is 24 after subtracting 126 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 14:
When dividing 240 by 63, we get 3 with a remainder of 51.
The number 3 becomes the next digit in our result. 
Result so far: 1998.23809523
Subtract 189 from 240 to get 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

The final result is 1998.23809523 with a remainder of 5.1e-08.
