We look at the division of 674681 by 51 
The aim is to understand the frequency of 51 in 674681.

Advancing to step 1:
When dividing 6 by 51, we get 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Take the next digit (7) from the dividend and append it to 6, then repeat: 67 / 51

Let's proceed to step 2:
67 divided by 51 is 1 with a remainder of 16.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 51 from 67, we get 16.
Grab the next digit (4) from the dividend, add it to 16, then carry on: 164 / 51

On to step 3:
The number 51 fits into 164 3 times, leaving a remainder of 11.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
The remainder is 11 after subtracting 153 from 164.
Fetch the next digit (6) from the dividend, attach it to 11 and continue: 116 / 51

Let's proceed to step 4:
51 goes into 116 2 times with a remainder of 14.
Write down 2 as next digit of the result. 
Result so far: 132.0
If we subtract 102 from 116, we get 14.
Fetch the next digit (8) from the dividend, attach it to 14 and continue: 148 / 51

On to step 5:
The number 51 fits into 148 2 times, leaving a remainder of 46.
Use 2 as the next digit of our solution. 
Result so far: 1322.0
Subtracting 102 from 148 leaves us with 46.
Take the next digit (1) from the dividend and append it to 46, then repeat: 461 / 51

Let's proceed to step 6:
The number 51 fits into 461 9 times, leaving a remainder of 2.
Write down 9 as next digit of the result. 
Result so far: 13229.0
Deduct 459 from 461 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 7:
When dividing 20 by 51, we get 0 with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 13229.0
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 8:
51 can be fit into 200 3 times, resulting in a remainder of 47.
Put 3 as the next digit of the answer. 
Result so far: 13229.03
Subtract 153 from 200 to get 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Going ahead to step 9:
When dividing 470 by 51, we get 9 with a remainder of 11.
The number 9 becomes the next digit in our result. 
Result so far: 13229.039
If we take 459 away from 470, we end up with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Let's proceed to step 10:
110 divided by 51 is 2 with a remainder of 8.
Record the quotient 2 as the next digit in the result. 
Result so far: 13229.0392
Subtract 102 from 110 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 11:
If we divide 80 by 51, we get 1 and a remainder of 29.
The next digit of our result is 1. 
Result so far: 13229.03921
If we subtract 51 from 80, we get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

On to step 12:
If we divide 290 by 51, we get 5 and a remainder of 35.
The number 5 becomes the next digit in our result. 
Result so far: 13229.039215
If we take 255 away from 290, we end up with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Let's proceed to step 13:
51 can be fit into 350 6 times, resulting in a remainder of 44.
The number 6 becomes the next digit in our result. 
Result so far: 13229.0392156
Subtracting 306 from 350 leaves us with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Going ahead to step 14:
51 goes into 440 8 times with a remainder of 32.
Write down 8 as next digit of the result. 
Result so far: 13229.03921568
The remainder is 32 after subtracting 408 from 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

In conclusion, the division gives 13229.03921568 with a balance of 3.2e-08.
