We're dividing 949858 by 63 
The aim is to understand the frequency of 63 in 949858.

On to step 1:
63 goes into 9 0 times with a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Append the next digit (4) from the dividend to 9 and continue with: 94 / 63

Advancing to step 2:
63 goes into 94 1 times with a remainder of 31.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 31 after subtracting 63 from 94.
Grab the next digit (9) from the dividend, add it to 31, then carry on: 319 / 63

Going ahead to step 3:
The number 63 fits into 319 5 times, leaving a remainder of 4.
The next digit of our result is 5. 
Result so far: 15.0
Subtract 315 from 319 to get 4.
Grab the next digit (8) from the dividend, add it to 4, then carry on: 48 / 63

Step 4:
63 can be fit into 48 0 times, resulting in a remainder of 48.
The number 0 becomes the next digit in our result. 
Result so far: 150.0
If we take 0 away from 48, we end up with 48.
Append the next digit (5) from the dividend to 48 and continue with: 485 / 63

Step 5:
485 divided by 63 is 7 with a remainder of 44.
The number 7 becomes the next digit in our result. 
Result so far: 1507.0
If we subtract 441 from 485, we get 44.
Include the next digit (8) from the dividend after 44, then repeat: 448 / 63

Step 6:
The number 63 fits into 448 7 times, leaving a remainder of 7.
Write down 7 as next digit of the result. 
Result so far: 15077.0
If we subtract 441 from 448, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 7:
63 can be fit into 70 1 times, resulting in a remainder of 7.
The next digit of our result is 1. 
Result so far: 15077.1
Subtracting 63 from 70 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

On to step 8:
If we divide 70 by 63, we get 1 and a remainder of 7.
Put 1 as the next digit of the answer. 
Result so far: 15077.11
Deduct 63 from 70 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

The final outcome is 15077.11, with a leftover of 0.007.
