We're dividing 829804 by 51 
The aim is to understand the frequency of 51 in 829804.

On to step 1:
When dividing 8 by 51, we get 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Take the next digit (2) from the dividend and append it to 8, then repeat: 82 / 51

Going ahead to step 2:
51 can be fit into 82 1 times, resulting in a remainder of 31.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 31 after subtracting 51 from 82.
Grab the next digit (9) from the dividend, add it to 31, then carry on: 319 / 51

Advancing to step 3:
The number 51 fits into 319 6 times, leaving a remainder of 13.
Use 6 as the next digit of our solution. 
Result so far: 16.0
If we take 306 away from 319, we end up with 13.
Append the next digit (8) from the dividend to 13 and continue with: 138 / 51

Advancing to step 4:
51 can be fit into 138 2 times, resulting in a remainder of 36.
The number 2 becomes the next digit in our result. 
Result so far: 162.0
If we subtract 102 from 138, we get 36.
Append the next digit (0) from the dividend to 36 and continue with: 360 / 51

Moving on to step 5:
When dividing 360 by 51, we get 7 with a remainder of 3.
Use 7 as the next digit of our solution. 
Result so far: 1627.0
The remainder is 3 after subtracting 357 from 360.
Grab the next digit (4) from the dividend, add it to 3, then carry on: 34 / 51

Step 6:
If we divide 34 by 51, we get 0 and a remainder of 34.
Record the quotient 0 as the next digit in the result. 
Result so far: 16270.0
If we subtract 0 from 34, we get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

On to step 7:
51 goes into 340 6 times with a remainder of 34.
The next digit of our result is 6. 
Result so far: 16270.6
Subtract 306 from 340 to get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

On to step 8:
When dividing 340 by 51, we get 6 with a remainder of 34.
Write down 6 as next digit of the result. 
Result so far: 16270.66
If we subtract 306 from 340, we get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

The final outcome is 16270.66, with a leftover of 0.034.
