We divide 66013933 by 799
The aim is to understand the frequency of 799 in 66013933.

Moving on to step 1:
6 divided by 799 is 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Include the next digit (6) from the dividend after 6, then repeat: 66 / 799

Let's proceed to step 2:
When dividing 66 by 799, we get 0 with a remainder of 66.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 66 after subtracting 0 from 66.
Bring next digit (0) of the dividend behind the 66 and repeat the process: 660 / 799

Moving on to step 3:
The number 799 fits into 660 0 times, leaving a remainder of 660.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 660 and we're left with 660.
Append the next digit (1) from the dividend to 660 and continue with: 6601 / 799

Let's proceed to step 4:
If we divide 6601 by 799, we get 8 and a remainder of 209.
The next digit of our result is 8. 
Result so far: 8.0
Subtract 6392 from 6601 to get 209.
Bring next digit (3) of the dividend behind the 209 and repeat the process: 2093 / 799

Let's proceed to step 5:
799 goes into 2093 2 times with a remainder of 495.
The number 2 becomes the next digit in our result. 
Result so far: 82.0
The remainder is 495 after subtracting 1598 from 2093.
Take the next digit (9) from the dividend and append it to 495, then repeat: 4959 / 799

Step 6:
If we divide 4959 by 799, we get 6 and a remainder of 165.
Record the quotient 6 as the next digit in the result. 
Result so far: 826.0
Deduct 4794 from 4959 and we're left with 165.
Fetch the next digit (3) from the dividend, attach it to 165 and continue: 1653 / 799

Going ahead to step 7:
The number 799 fits into 1653 2 times, leaving a remainder of 55.
Put 2 as the next digit of the answer. 
Result so far: 8262.0
Subtract 1598 from 1653 to get 55.
Append the next digit (3) from the dividend to 55 and continue with: 553 / 799

Going ahead to step 8:
If we divide 553 by 799, we get 0 and a remainder of 553.
Use 0 as the next digit of our solution. 
Result so far: 82620.0
If we take 0 away from 553, we end up with 553.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5530, and continue the process.

On to step 9:
799 goes into 5530 6 times with a remainder of 736.
The number 6 becomes the next digit in our result. 
Result so far: 82620.6
Deduct 4794 from 5530 and we're left with 736.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7360, and continue the process.

On to step 10:
7360 divided by 799 is 9 with a remainder of 169.
Write down 9 as next digit of the result. 
Result so far: 82620.69
If we subtract 7191 from 7360, we get 169.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1690, and continue the process.

On to step 11:
799 can be fit into 1690 2 times, resulting in a remainder of 92.
Record the quotient 2 as the next digit in the result. 
Result so far: 82620.692
If we take 1598 away from 1690, we end up with 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

On to step 12:
If we divide 920 by 799, we get 1 and a remainder of 121.
Use 1 as the next digit of our solution. 
Result so far: 82620.6921
Subtracting 799 from 920 leaves us with 121.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1210, and continue the process.

Advancing to step 13:
799 goes into 1210 1 times with a remainder of 411.
Record the quotient 1 as the next digit in the result. 
Result so far: 82620.69211
The remainder is 411 after subtracting 799 from 1210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4110, and continue the process.

The final result is 82620.69211 with a remainder of 0.000411.
