We're dividing 866953 by 63 
The aim is to understand the frequency of 63 in 866953.

On to step 1:
When dividing 8 by 63, we get 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Fetch the next digit (6) from the dividend, attach it to 8 and continue: 86 / 63

Step 2:
86 divided by 63 is 1 with a remainder of 23.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 23 after subtracting 63 from 86.
Fetch the next digit (6) from the dividend, attach it to 23 and continue: 236 / 63

Advancing to step 3:
63 goes into 236 3 times with a remainder of 47.
Write down 3 as next digit of the result. 
Result so far: 13.0
If we take 189 away from 236, we end up with 47.
Grab the next digit (9) from the dividend, add it to 47, then carry on: 479 / 63

Moving on to step 4:
If we divide 479 by 63, we get 7 and a remainder of 38.
Record the quotient 7 as the next digit in the result. 
Result so far: 137.0
If we subtract 441 from 479, we get 38.
Include the next digit (5) from the dividend after 38, then repeat: 385 / 63

Let's proceed to step 5:
385 divided by 63 is 6 with a remainder of 7.
Write down 6 as next digit of the result. 
Result so far: 1376.0
Subtracting 378 from 385 leaves us with 7.
Fetch the next digit (3) from the dividend, attach it to 7 and continue: 73 / 63

Advancing to step 6:
The number 63 fits into 73 1 times, leaving a remainder of 10.
The next digit of our result is 1. 
Result so far: 13761.0
If we take 63 away from 73, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 7:
The number 63 fits into 100 1 times, leaving a remainder of 37.
The number 1 becomes the next digit in our result. 
Result so far: 13761.1
Subtracting 63 from 100 leaves us with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Let's proceed to step 8:
When dividing 370 by 63, we get 5 with a remainder of 55.
Use 5 as the next digit of our solution. 
Result so far: 13761.15
If we subtract 315 from 370, we get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

On to step 9:
If we divide 550 by 63, we get 8 and a remainder of 46.
Use 8 as the next digit of our solution. 
Result so far: 13761.158
Subtract 504 from 550 to get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

On to step 10:
If we divide 460 by 63, we get 7 and a remainder of 19.
Record the quotient 7 as the next digit in the result. 
Result so far: 13761.1587
If we take 441 away from 460, we end up with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Step 11:
63 can be fit into 190 3 times, resulting in a remainder of 1.
Record the quotient 3 as the next digit in the result. 
Result so far: 13761.15873
The remainder is 1 after subtracting 189 from 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 12:
10 divided by 63 is 0 with a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 13761.15873
Subtract 0 from 10 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 13:
If we divide 100 by 63, we get 1 and a remainder of 37.
Write down 1 as next digit of the result. 
Result so far: 13761.1587301
If we take 63 away from 100, we end up with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Let's proceed to step 14:
63 goes into 370 5 times with a remainder of 55.
The next digit of our result is 5. 
Result so far: 13761.15873015
Subtract 315 from 370 to get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

In conclusion, the division gives 13761.15873015 with a balance of 5.5e-08.
