We're dividing 579638 by 51 
The aim is to understand the frequency of 51 in 579638.

Step 1:
The number 51 fits into 5 0 times, leaving a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Grab the next digit (7) from the dividend, add it to 5, then carry on: 57 / 51

Step 2:
57 divided by 51 is 1 with a remainder of 6.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 51 from 57, we get 6.
Append the next digit (9) from the dividend to 6 and continue with: 69 / 51

On to step 3:
69 divided by 51 is 1 with a remainder of 18.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
Subtracting 51 from 69 leaves us with 18.
Take the next digit (6) from the dividend and append it to 18, then repeat: 186 / 51

Moving on to step 4:
When dividing 186 by 51, we get 3 with a remainder of 33.
Record the quotient 3 as the next digit in the result. 
Result so far: 113.0
If we subtract 153 from 186, we get 33.
Include the next digit (3) from the dividend after 33, then repeat: 333 / 51

Advancing to step 5:
333 divided by 51 is 6 with a remainder of 27.
Put 6 as the next digit of the answer. 
Result so far: 1136.0
Subtract 306 from 333 to get 27.
Grab the next digit (8) from the dividend, add it to 27, then carry on: 278 / 51

On to step 6:
If we divide 278 by 51, we get 5 and a remainder of 23.
Record the quotient 5 as the next digit in the result. 
Result so far: 11365.0
The remainder is 23 after subtracting 255 from 278.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Let's proceed to step 7:
51 can be fit into 230 4 times, resulting in a remainder of 26.
The next digit of our result is 4. 
Result so far: 11365.4
Deduct 204 from 230 and we're left with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Going ahead to step 8:
51 goes into 260 5 times with a remainder of 5.
The next digit of our result is 5. 
Result so far: 11365.45
If we take 255 away from 260, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 9:
51 goes into 50 0 times with a remainder of 50.
The next digit of our result is 0. 
Result so far: 11365.45
If we subtract 0 from 50, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 10:
51 can be fit into 500 9 times, resulting in a remainder of 41.
The number 9 becomes the next digit in our result. 
Result so far: 11365.4509
The remainder is 41 after subtracting 459 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Advancing to step 11:
The number 51 fits into 410 8 times, leaving a remainder of 2.
Use 8 as the next digit of our solution. 
Result so far: 11365.45098
Deduct 408 from 410 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.

Let's proceed to step 12:
The number 51 fits into 20 0 times, leaving a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 11365.45098
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.

Moving on to step 13:
When dividing 200 by 51, we get 3 with a remainder of 47.
Put 3 as the next digit of the answer. 
Result so far: 11365.4509803
If we take 153 away from 200, we end up with 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 14:
When dividing 470 by 51, we get 9 with a remainder of 11.
Put 9 as the next digit of the answer. 
Result so far: 11365.45098039
Subtracting 459 from 470 leaves us 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.

Our division results in 11365.45098039 with a remaining 1.1e-08.
