We look at the division of 814579 by 51 
The aim is to understand the frequency of 51 in 814579.

Going ahead to step 1:
51 goes into 8 0 times with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Take the next digit (1) from the dividend and append it to 8, then repeat: 81 / 51

Moving on to step 2:
If we divide 81 by 51, we get 1 and a remainder of 30.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 51 from 81, we get 30.
Bring next digit (4) of the dividend behind the 30 and repeat the process: 304 / 51

Step 3:
304 divided by 51 is 5 with a remainder of 49.
Use 5 as the next digit of our solution. 
Result so far: 15.0
Subtracting 255 from 304 leaves us with 49.
Append the next digit (5) from the dividend to 49 and continue with: 495 / 51

Step 4:
51 can be fit into 495 9 times, resulting in a remainder of 36.
The number 9 becomes the next digit in our result. 
Result so far: 159.0
The remainder is 36 after subtracting 459 from 495.
Fetch the next digit (7) from the dividend, attach it to 36 and continue: 367 / 51

Let's proceed to step 5:
51 goes into 367 7 times with a remainder of 10.
Put 7 as the next digit of the answer. 
Result so far: 1597.0
Subtract 357 from 367 to get 10.
Grab the next digit (9) from the dividend, add it to 10, then carry on: 109 / 51

On to step 6:
When dividing 109 by 51, we get 2 with a remainder of 7.
Put 2 as the next digit of the answer. 
Result so far: 15972.0
Deduct 102 from 109 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 7:
When dividing 70 by 51, we get 1 with a remainder of 19.
Put 1 as the next digit of the answer. 
Result so far: 15972.1
Deduct 51 from 70 and we're left with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Going ahead to step 8:
51 can be fit into 190 3 times, resulting in a remainder of 37.
Write down 3 as next digit of the result. 
Result so far: 15972.13
The remainder is 37 after subtracting 153 from 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Going ahead to step 9:
If we divide 370 by 51, we get 7 and a remainder of 13.
The number 7 becomes the next digit in our result. 
Result so far: 15972.137
The remainder is 13 after subtracting 357 from 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Step 10:
130 divided by 51 is 2 with a remainder of 28.
Record the quotient 2 as the next digit in the result. 
Result so far: 15972.1372
Subtract 102 from 130 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Advancing to step 11:
If we divide 280 by 51, we get 5 and a remainder of 25.
Write down 5 as next digit of the result. 
Result so far: 15972.13725
Subtracting 255 from 280 leaves us with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Advancing to step 12:
When dividing 250 by 51, we get 4 with a remainder of 46.
Write down 4 as next digit of the result. 
Result so far: 15972.137254
If we subtract 204 from 250, we get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Advancing to step 13:
51 can be fit into 460 9 times, resulting in a remainder of 1.
Write down 9 as next digit of the result. 
Result so far: 15972.1372549
If we subtract 459 from 460, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 14:
If we divide 10 by 51, we get 0 and a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 15972.1372549
If we take 0 away from 10, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The final result is 15972.1372549 with a remainder of 1e-08.
