We're dividing 939381 by 63 
The aim is to understand the frequency of 63 in 939381.

On to step 1:
The number 63 fits into 9 0 times, leaving a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Grab the next digit (3) from the dividend, add it to 9, then carry on: 93 / 63

On to step 2:
The number 63 fits into 93 1 times, leaving a remainder of 30.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 63 from 93, we get 30.
Bring next digit (9) of the dividend behind the 30 and repeat the process: 309 / 63

Moving on to step 3:
63 can be fit into 309 4 times, resulting in a remainder of 57.
Use 4 as the next digit of our solution. 
Result so far: 14.0
The remainder is 57 after subtracting 252 from 309.
Take the next digit (3) from the dividend and append it to 57, then repeat: 573 / 63

Advancing to step 4:
63 goes into 573 9 times with a remainder of 6.
Write down 9 as next digit of the result. 
Result so far: 149.0
Subtract 567 from 573 to get 6.
Append the next digit (8) from the dividend to 6 and continue with: 68 / 63

Advancing to step 5:
68 divided by 63 is 1 with a remainder of 5.
Write down 1 as next digit of the result. 
Result so far: 1491.0
If we take 63 away from 68, we end up with 5.
Bring next digit (1) of the dividend behind the 5 and repeat the process: 51 / 63

Advancing to step 6:
63 goes into 51 0 times with a remainder of 51.
Put 0 as the next digit of the answer. 
Result so far: 14910.0
Deduct 0 from 51 and we're left with 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 7:
63 goes into 510 8 times with a remainder of 6.
Use 8 as the next digit of our solution. 
Result so far: 14910.8
Deduct 504 from 510 and we're left 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 8:
The number 63 fits into 60 0 times, leaving a remainder of 60.
Write down 0 as next digit of the result. 
Result so far: 14910.8
Subtracting 0 from 60 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 9:
63 goes into 600 9 times with a remainder of 33.
The next digit of our result is 9. 
Result so far: 14910.809
If we take 567 away from 600, we end up 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.

Advancing to step 10:
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: 14910.8095
Subtract 315 from 330 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 11:
When dividing 150 by 63, we get 2 with a remainder of 24.
Record the quotient 2 as the next digit in the result. 
Result so far: 14910.80952
Deduct 126 from 150 and we're left 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 12:
The number 63 fits into 240 3 times, leaving a remainder of 51.
Record the quotient 3 as the next digit in the result. 
Result so far: 14910.809523
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.

On to step 13:
63 can be fit into 510 8 times, resulting in a remainder of 6.
Record the quotient 8 as the next digit in the result. 
Result so far: 14910.8095238
Deduct 504 from 510 and we're left 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.

Step 14:
60 divided by 63 is 0 with a remainder of 60.
Record the quotient 0 as the next digit in the result. 
Result so far: 14910.8095238
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.

The final result is 14910.8095238 with a remainder of 6e-08.
