Let's divide 808628 by 51
The aim is to understand the frequency of 51 in 808628.

Moving on to step 1:
51 goes into 8 0 times with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Append the next digit (0) from the dividend to 8 and continue with: 80 / 51

Going ahead to step 2:
80 divided by 51 is 1 with a remainder of 29.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 51 from 80, we get 29.
Include the next digit (8) from the dividend after 29, then repeat: 298 / 51

Going ahead to step 3:
51 goes into 298 5 times with a remainder of 43.
Use 5 as the next digit of our solution. 
Result so far: 15.0
Deduct 255 from 298 and we're left with 43.
Append the next digit (6) from the dividend to 43 and continue with: 436 / 51

Advancing to step 4:
The number 51 fits into 436 8 times, leaving a remainder of 28.
Record the quotient 8 as the next digit in the result. 
Result so far: 158.0
If we take 408 away from 436, we end up with 28.
Fetch the next digit (2) from the dividend, attach it to 28 and continue: 282 / 51

Advancing to step 5:
51 goes into 282 5 times with a remainder of 27.
The next digit of our result is 5. 
Result so far: 1585.0
If we take 255 away from 282, we end up with 27.
Fetch the next digit (8) from the dividend, attach it to 27 and continue: 278 / 51

Moving on to step 6:
51 can be fit into 278 5 times, resulting in a remainder of 23.
Put 5 as the next digit of the answer. 
Result so far: 15855.0
Deduct 255 from 278 and we're left with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Going ahead to step 7:
51 can be fit into 230 4 times, resulting in a remainder of 26.
Put 4 as the next digit of the answer. 
Result so far: 15855.4
The remainder is 26 after subtracting 204 from 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Advancing to step 8:
51 can be fit into 260 5 times, resulting in a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 15855.45
Subtract 255 from 260 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 9:
The number 51 fits into 50 0 times, leaving a remainder of 50.
The number 0 becomes the next digit in our result. 
Result so far: 15855.45
If we subtract 0 from 50, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 10:
When dividing 500 by 51, we get 9 with a remainder of 41.
The number 9 becomes the next digit in our result. 
Result so far: 15855.4509
If we subtract 459 from 500, we get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Step 11:
When dividing 410 by 51, we get 8 with a remainder of 2.
The next digit of our result is 8. 
Result so far: 15855.45098
Subtract 408 from 410 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 12:
20 divided by 51 is 0 with a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 15855.45098
Subtracting 0 from 20 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 13:
200 divided by 51 is 3 with a remainder of 47.
Write down 3 as next digit of the result. 
Result so far: 15855.4509803
If we take 153 away from 200, we end up with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Step 14:
The number 51 fits into 470 9 times, leaving a remainder of 11.
Write down 9 as next digit of the result. 
Result so far: 15855.45098039
The remainder is 11 after subtracting 459 from 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

The final outcome is 15855.45098039, with a leftover of 1.1e-08.
