We're dividing 63425048 by 811 
The aim is to understand the frequency of 811 in 63425048.

Going ahead to step 1:
If we divide 6 by 811, we get 0 and a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Grab the next digit (3) from the dividend, add it to 6, then carry on: 63 / 811

Step 2:
The number 811 fits into 63 0 times, leaving a remainder of 63.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 63, we get 63.
Fetch the next digit (4) from the dividend, attach it to 63 and continue: 634 / 811

On to step 3:
634 divided by 811 is 0 with a remainder of 634.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 634, we get 634.
Bring next digit (2) of the dividend behind the 634 and repeat the process: 6342 / 811

Going ahead to step 4:
811 goes into 6342 7 times with a remainder of 665.
Write down 7 as next digit of the result. 
Result so far: 7.0
If we subtract 5677 from 6342, we get 665.
Take the next digit (5) from the dividend and append it to 665, then repeat: 6655 / 811

Going ahead to step 5:
6655 divided by 811 is 8 with a remainder of 167.
Put 8 as the next digit of the answer. 
Result so far: 78.0
If we take 6488 away from 6655, we end up with 167.
Bring next digit (0) of the dividend behind the 167 and repeat the process: 1670 / 811

Step 6:
The number 811 fits into 1670 2 times, leaving a remainder of 48.
The number 2 becomes the next digit in our result. 
Result so far: 782.0
Subtract 1622 from 1670 to get 48.
Include the next digit (4) from the dividend after 48, then repeat: 484 / 811

Going ahead to step 7:
811 can be fit into 484 0 times, resulting in a remainder of 484.
Write down 0 as next digit of the result. 
Result so far: 7820.0
If we take 0 away from 484, we end up with 484.
Bring next digit (8) of the dividend behind the 484 and repeat the process: 4848 / 811

Going ahead to step 8:
The number 811 fits into 4848 5 times, leaving a remainder of 793.
The number 5 becomes the next digit in our result. 
Result so far: 78205.0
If we subtract 4055 from 4848, we get 793.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7930, and continue the process.

Let's proceed to step 9:
When dividing 7930 by 811, we get 9 with a remainder of 631.
Write down 9 as next digit of the result. 
Result so far: 78205.9
If we subtract 7299 from 7930, we get 631.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6310, and continue the process.

Moving on to step 10:
When dividing 6310 by 811, we get 7 with a remainder of 633.
The number 7 becomes the next digit in our result. 
Result so far: 78205.97
Subtracting 5677 from 6310 leaves us with 633.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6330, and continue the process.

On to step 11:
6330 divided by 811 is 7 with a remainder of 653.
The number 7 becomes the next digit in our result. 
Result so far: 78205.977
The remainder is 653 after subtracting 5677 from 6330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6530, and continue the process.

The final result is 78205.977 with a remainder of 0.0653.
