Let's divide 812400 by 63
The aim is to understand the frequency of 63 in 812400.

Let's proceed to step 1:
If we divide 8 by 63, we get 0 and a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Include the next digit (1) from the dividend after 8, then repeat: 81 / 63

Step 2:
The number 63 fits into 81 1 times, leaving a remainder of 18.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 18 after subtracting 63 from 81.
Include the next digit (2) from the dividend after 18, then repeat: 182 / 63

Let's proceed to step 3:
The number 63 fits into 182 2 times, leaving a remainder of 56.
Use 2 as the next digit of our solution. 
Result so far: 12.0
If we subtract 126 from 182, we get 56.
Append the next digit (4) from the dividend to 56 and continue with: 564 / 63

Let's proceed to step 4:
564 divided by 63 is 8 with a remainder of 60.
Write down 8 as next digit of the result. 
Result so far: 128.0
Deduct 504 from 564 and we're left with 60.
Bring next digit (0) of the dividend behind the 60 and repeat the process: 600 / 63

Let's proceed to step 5:
If we divide 600 by 63, we get 9 and a remainder of 33.
Write down 9 as next digit of the result. 
Result so far: 1289.0
If we take 567 away from 600, we end up with 33.
Grab the next digit (0) from the dividend, add it to 33, then carry on: 330 / 63

Advancing to step 6:
63 can be fit into 330 5 times, resulting in a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 12895.0
If we subtract 315 from 330, we 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.

Let's proceed to step 7:
150 divided by 63 is 2 with a remainder of 24.
Write down 2 as next digit of the result. 
Result so far: 12895.2
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.

Going ahead to step 8:
63 goes into 240 3 times with a remainder of 51.
Write down 3 as next digit of the result. 
Result so far: 12895.23
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:
The number 63 fits into 510 8 times, leaving a remainder of 6.
Use 8 as the next digit of our solution. 
Result so far: 12895.238
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.

Let's proceed to step 10:
60 divided by 63 is 0 with a remainder of 60.
The next digit of our result is 0. 
Result so far: 12895.238
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.

Step 11:
If we divide 600 by 63, we get 9 and a remainder of 33.
Write down 9 as next digit of the result. 
Result so far: 12895.23809
Deduct 567 from 600 and we're left 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 12:
The number 63 fits into 330 5 times, leaving a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 12895.238095
The remainder is 15 after subtracting 315 from 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 13:
If we divide 150 by 63, we get 2 and a remainder of 24.
Put 2 as the next digit of the answer. 
Result so far: 12895.2380952
Subtract 126 from 150 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 14:
If we divide 240 by 63, we get 3 and a remainder of 51.
Record the quotient 3 as the next digit in the result. 
Result so far: 12895.23809523
Subtracting 189 from 240 leaves us 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.

The final outcome is 12895.23809523, with a leftover of 5.1e-08.
