We look at the division of 65340631 by 799 
The aim is to understand the frequency of 799 in 65340631.

Let's proceed to step 1:
799 goes into 6 0 times with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Grab the next digit (5) from the dividend, add it to 6, then carry on: 65 / 799

Let's proceed to step 2:
799 can be fit into 65 0 times, resulting in a remainder of 65.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 65 leaves us with 65.
Take the next digit (3) from the dividend and append it to 65, then repeat: 653 / 799

On to step 3:
If we divide 653 by 799, we get 0 and a remainder of 653.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 653 and we're left with 653.
Bring next digit (4) of the dividend behind the 653 and repeat the process: 6534 / 799

On to step 4:
When dividing 6534 by 799, we get 8 with a remainder of 142.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Subtracting 6392 from 6534 leaves us with 142.
Bring next digit (0) of the dividend behind the 142 and repeat the process: 1420 / 799

Going ahead to step 5:
799 can be fit into 1420 1 times, resulting in a remainder of 621.
Record the quotient 1 as the next digit in the result. 
Result so far: 81.0
Subtract 799 from 1420 to get 621.
Include the next digit (6) from the dividend after 621, then repeat: 6216 / 799

Step 6:
799 goes into 6216 7 times with a remainder of 623.
Record the quotient 7 as the next digit in the result. 
Result so far: 817.0
If we subtract 5593 from 6216, we get 623.
Grab the next digit (3) from the dividend, add it to 623, then carry on: 6233 / 799

Step 7:
If we divide 6233 by 799, we get 7 and a remainder of 640.
The next digit of our result is 7. 
Result so far: 8177.0
Deduct 5593 from 6233 and we're left with 640.
Append the next digit (1) from the dividend to 640 and continue with: 6401 / 799

Step 8:
The number 799 fits into 6401 8 times, leaving a remainder of 9.
Record the quotient 8 as the next digit in the result. 
Result so far: 81778.0
If we subtract 6392 from 6401, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Moving on to step 9:
The number 799 fits into 90 0 times, leaving a remainder of 90.
Put 0 as the next digit of the answer. 
Result so far: 81778.0
If we subtract 0 from 90, we get 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

On to step 10:
If we divide 900 by 799, we get 1 and a remainder of 101.
The next digit of our result is 1. 
Result so far: 81778.01
Deduct 799 from 900 and we're left with 101.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1010, and continue the process.

On to step 11:
When dividing 1010 by 799, we get 1 with a remainder of 211.
Put 1 as the next digit of the answer. 
Result so far: 81778.011
If we take 799 away from 1010, we end up with 211.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2110, and continue the process.

The final outcome is 81778.011, with a leftover of 0.0211.
