566375 ÷ 51 
The aim is to understand the frequency of 51 in 566375.

On to step 1:
5 divided by 51 is 0 with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Include the next digit (6) from the dividend after 5, then repeat: 56 / 51

Going ahead to step 2:
If we divide 56 by 51, we get 1 and a remainder of 5.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 5 after subtracting 51 from 56.
Append the next digit (6) from the dividend to 5 and continue with: 56 / 51

On to step 3:
56 divided by 51 is 1 with a remainder of 5.
The next digit of our result is 1. 
Result so far: 11.0
Subtract 51 from 56 to get 5.
Bring next digit (3) of the dividend behind the 5 and repeat the process: 53 / 51

Let's proceed to step 4:
51 can be fit into 53 1 times, resulting in a remainder of 2.
Write down 1 as next digit of the result. 
Result so far: 111.0
The remainder is 2 after subtracting 51 from 53.
Include the next digit (7) from the dividend after 2, then repeat: 27 / 51

Step 5:
51 goes into 27 0 times with a remainder of 27.
Put 0 as the next digit of the answer. 
Result so far: 1110.0
If we take 0 away from 27, we end up with 27.
Bring next digit (5) of the dividend behind the 27 and repeat the process: 275 / 51

Step 6:
If we divide 275 by 51, we get 5 and a remainder of 20.
Write down 5 as next digit of the result. 
Result so far: 11105.0
If we subtract 255 from 275, 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 7:
51 can be fit into 200 3 times, resulting in a remainder of 47.
Use 3 as the next digit of our solution. 
Result so far: 11105.3
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.

On to step 8:
When dividing 470 by 51, we get 9 with a remainder of 11.
Write down 9 as next digit of the result. 
Result so far: 11105.39
The remainder is 11 after subtracting 459 from 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Moving on to step 9:
If we divide 110 by 51, we get 2 and a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 11105.392
If we subtract 102 from 110, we 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.

Advancing to step 10:
51 goes into 80 1 times with a remainder of 29.
Use 1 as the next digit of our solution. 
Result so far: 11105.3921
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 11:
290 divided by 51 is 5 with a remainder of 35.
Record the quotient 5 as the next digit in the result. 
Result so far: 11105.39215
Subtract 255 from 290 to get 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 12:
51 goes into 350 6 times with a remainder of 44.
The next digit of our result is 6. 
Result so far: 11105.392156
Subtract 306 from 350 to get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Moving on to step 13:
51 goes into 440 8 times with a remainder of 32.
Use 8 as the next digit of our solution. 
Result so far: 11105.3921568
If we take 408 away from 440, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 14:
The number 51 fits into 320 6 times, leaving a remainder of 14.
Put 6 as the next digit of the answer. 
Result so far: 11105.39215686
If we take 306 away from 320, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Our division results in 11105.39215686 with a remaining 1.4e-08.
