We look at the division of 847417 by 51 
The aim is to understand the frequency of 51 in 847417.

Advancing to step 1:
8 divided by 51 is 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Fetch the next digit (4) from the dividend, attach it to 8 and continue: 84 / 51

On to step 2:
The number 51 fits into 84 1 times, leaving a remainder of 33.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 51 from 84, we get 33.
Include the next digit (7) from the dividend after 33, then repeat: 337 / 51

On to step 3:
337 divided by 51 is 6 with a remainder of 31.
Put 6 as the next digit of the answer. 
Result so far: 16.0
Subtract 306 from 337 to get 31.
Grab the next digit (4) from the dividend, add it to 31, then carry on: 314 / 51

Going ahead to step 4:
When dividing 314 by 51, we get 6 with a remainder of 8.
The next digit of our result is 6. 
Result so far: 166.0
The remainder is 8 after subtracting 306 from 314.
Include the next digit (1) from the dividend after 8, then repeat: 81 / 51

Step 5:
81 divided by 51 is 1 with a remainder of 30.
Put 1 as the next digit of the answer. 
Result so far: 1661.0
Subtract 51 from 81 to get 30.
Grab the next digit (7) from the dividend, add it to 30, then carry on: 307 / 51

On to step 6:
When dividing 307 by 51, we get 6 with a remainder of 1.
Record the quotient 6 as the next digit in the result. 
Result so far: 16616.0
Subtracting 306 from 307 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 7:
The number 51 fits into 10 0 times, leaving a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 16616.0
Subtracting 0 from 10 leaves us 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.

Advancing to step 8:
100 divided by 51 is 1 with a remainder of 49.
Write down 1 as next digit of the result. 
Result so far: 16616.01
Deduct 51 from 100 and we're left with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Let's proceed to step 9:
51 can be fit into 490 9 times, resulting in a remainder of 31.
The next digit of our result is 9. 
Result so far: 16616.019
The remainder is 31 after subtracting 459 from 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Step 10:
If we divide 310 by 51, we get 6 and a remainder of 4.
Put 6 as the next digit of the answer. 
Result so far: 16616.0196
The remainder is 4 after subtracting 306 from 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 11:
The number 51 fits into 40 0 times, leaving a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 16616.0196
The remainder is 40 after subtracting 0 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 12:
If we divide 400 by 51, we get 7 and a remainder of 43.
The next digit of our result is 7. 
Result so far: 16616.019607
The remainder is 43 after subtracting 357 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Going ahead to step 13:
When dividing 430 by 51, we get 8 with a remainder of 22.
The next digit of our result is 8. 
Result so far: 16616.0196078
If we subtract 408 from 430, we 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 14:
220 divided by 51 is 4 with a remainder of 16.
Record the quotient 4 as the next digit in the result. 
Result so far: 16616.01960784
If we take 204 away from 220, we end up 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.

The final result is 16616.01960784 with a remainder of 1.6e-08.
