We're dividing 968679 by 51 
The aim is to understand the frequency of 51 in 968679.

Advancing to step 1:
When dividing 9 by 51, we get 0 with a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Append the next digit (6) from the dividend to 9 and continue with: 96 / 51

Going ahead to step 2:
51 goes into 96 1 times with a remainder of 45.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 51 away from 96, we end up with 45.
Grab the next digit (8) from the dividend, add it to 45, then carry on: 458 / 51

On to step 3:
The number 51 fits into 458 8 times, leaving a remainder of 50.
The number 8 becomes the next digit in our result. 
Result so far: 18.0
Subtract 408 from 458 to get 50.
Bring next digit (6) of the dividend behind the 50 and repeat the process: 506 / 51

Step 4:
When dividing 506 by 51, we get 9 with a remainder of 47.
The next digit of our result is 9. 
Result so far: 189.0
If we subtract 459 from 506, we get 47.
Grab the next digit (7) from the dividend, add it to 47, then carry on: 477 / 51

Moving on to step 5:
51 goes into 477 9 times with a remainder of 18.
The number 9 becomes the next digit in our result. 
Result so far: 1899.0
Subtracting 459 from 477 leaves us with 18.
Take the next digit (9) from the dividend and append it to 18, then repeat: 189 / 51

Advancing to step 6:
If we divide 189 by 51, we get 3 and a remainder of 36.
Record the quotient 3 as the next digit in the result. 
Result so far: 18993.0
The remainder is 36 after subtracting 153 from 189.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Let's proceed to step 7:
The number 51 fits into 360 7 times, leaving a remainder of 3.
The number 7 becomes the next digit in our result. 
Result so far: 18993.7
Deduct 357 from 360 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 8:
30 divided by 51 is 0 with a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 18993.7
The remainder is 30 after subtracting 0 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 9:
51 goes into 300 5 times with a remainder of 45.
The number 5 becomes the next digit in our result. 
Result so far: 18993.705
If we take 255 away from 300, we end up with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Step 10:
If we divide 450 by 51, we get 8 and a remainder of 42.
Use 8 as the next digit of our solution. 
Result so far: 18993.7058
If we take 408 away from 450, we end up with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Moving on to step 11:
51 can be fit into 420 8 times, resulting in a remainder of 12.
Use 8 as the next digit of our solution. 
Result so far: 18993.70588
Subtract 408 from 420 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

In conclusion, the division gives 18993.70588 with a balance of 1.2e-05.
