We're dividing 471874 by 51 
The aim is to understand the frequency of 51 in 471874.

Step 1:
The number 51 fits into 4 0 times, leaving a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Append the next digit (7) from the dividend to 4 and continue with: 47 / 51

Going ahead to step 2:
51 goes into 47 0 times with a remainder of 47.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 47, we get 47.
Include the next digit (1) from the dividend after 47, then repeat: 471 / 51

Step 3:
If we divide 471 by 51, we get 9 and a remainder of 12.
Write down 9 as next digit of the result. 
Result so far: 9.0
Subtracting 459 from 471 leaves us with 12.
Include the next digit (8) from the dividend after 12, then repeat: 128 / 51

On to step 4:
If we divide 128 by 51, we get 2 and a remainder of 26.
The number 2 becomes the next digit in our result. 
Result so far: 92.0
If we subtract 102 from 128, we get 26.
Bring next digit (7) of the dividend behind the 26 and repeat the process: 267 / 51

Step 5:
267 divided by 51 is 5 with a remainder of 12.
Write down 5 as next digit of the result. 
Result so far: 925.0
The remainder is 12 after subtracting 255 from 267.
Append the next digit (4) from the dividend to 12 and continue with: 124 / 51

Advancing to step 6:
51 can be fit into 124 2 times, resulting in a remainder of 22.
Write down 2 as next digit of the result. 
Result so far: 9252.0
Subtract 102 from 124 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 7:
220 divided by 51 is 4 with a remainder of 16.
Put 4 as the next digit of the answer. 
Result so far: 9252.4
Deduct 204 from 220 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 8:
When dividing 160 by 51, we get 3 with a remainder of 7.
Record the quotient 3 as the next digit in the result. 
Result so far: 9252.43
The remainder is 7 after subtracting 153 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 9:
If we divide 70 by 51, we get 1 and a remainder of 19.
Put 1 as the next digit of the answer. 
Result so far: 9252.431
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.

Step 10:
51 goes into 190 3 times with a remainder of 37.
Put 3 as the next digit of the answer. 
Result so far: 9252.4313
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.

On to step 11:
The number 51 fits into 370 7 times, leaving a remainder of 13.
The next digit of our result is 7. 
Result so far: 9252.43137
If we take 357 away from 370, we end up with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Advancing to step 12:
If we divide 130 by 51, we get 2 and a remainder of 28.
Record the quotient 2 as the next digit in the result. 
Result so far: 9252.431372
The remainder is 28 after subtracting 102 from 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

On to step 13:
51 goes into 280 5 times with a remainder of 25.
The next digit of our result is 5. 
Result so far: 9252.4313725
If we take 255 away from 280, we end up 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.

Moving on to step 14:
If we divide 250 by 51, we get 4 and a remainder of 46.
Put 4 as the next digit of the answer. 
Result so far: 9252.43137254
Subtracting 204 from 250 leaves us with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

The final result is 9252.43137254 with a remainder of 4.6e-08.
