Let's divide 606685 by 51
The aim is to understand the frequency of 51 in 606685.

Moving on to step 1:
If we divide 6 by 51, we get 0 and a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Bring next digit (0) of the dividend behind the 6 and repeat the process: 60 / 51

Moving on to step 2:
If we divide 60 by 51, we get 1 and a remainder of 9.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 51 from 60 and we're left with 9.
Include the next digit (6) from the dividend after 9, then repeat: 96 / 51

Going ahead to step 3:
96 divided by 51 is 1 with a remainder of 45.
Use 1 as the next digit of our solution. 
Result so far: 11.0
The remainder is 45 after subtracting 51 from 96.
Take the next digit (6) from the dividend and append it to 45, then repeat: 456 / 51

On to step 4:
The number 51 fits into 456 8 times, leaving a remainder of 48.
Put 8 as the next digit of the answer. 
Result so far: 118.0
Deduct 408 from 456 and we're left with 48.
Grab the next digit (8) from the dividend, add it to 48, then carry on: 488 / 51

Advancing to step 5:
488 divided by 51 is 9 with a remainder of 29.
Write down 9 as next digit of the result. 
Result so far: 1189.0
Subtracting 459 from 488 leaves us with 29.
Take the next digit (5) from the dividend and append it to 29, then repeat: 295 / 51

Let's proceed to step 6:
295 divided by 51 is 5 with a remainder of 40.
The next digit of our result is 5. 
Result so far: 11895.0
Deduct 255 from 295 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 7:
When dividing 400 by 51, we get 7 with a remainder of 43.
Record the quotient 7 as the next digit in the result. 
Result so far: 11895.7
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.

On to step 8:
430 divided by 51 is 8 with a remainder of 22.
Put 8 as the next digit of the answer. 
Result so far: 11895.78
The remainder is 22 after subtracting 408 from 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 9:
51 goes into 220 4 times with a remainder of 16.
Write down 4 as next digit of the result. 
Result so far: 11895.784
Subtract 204 from 220 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 10:
160 divided by 51 is 3 with a remainder of 7.
The number 3 becomes the next digit in our result. 
Result so far: 11895.7843
If we subtract 153 from 160, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Step 11:
When dividing 70 by 51, we get 1 with a remainder of 19.
The number 1 becomes the next digit in our result. 
Result so far: 11895.78431
If we subtract 51 from 70, we get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Going ahead to step 12:
51 can be fit into 190 3 times, resulting in a remainder of 37.
Put 3 as the next digit of the answer. 
Result so far: 11895.784313
Deduct 153 from 190 and we're left with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Moving on to step 13:
If we divide 370 by 51, we get 7 and a remainder of 13.
The number 7 becomes the next digit in our result. 
Result so far: 11895.7843137
The remainder is 13 after subtracting 357 from 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Moving on to step 14:
51 can be fit into 130 2 times, resulting in a remainder of 28.
Use 2 as the next digit of our solution. 
Result so far: 11895.78431372
The remainder is 28 after subtracting 102 from 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

The final result is 11895.78431372 with a remainder of 2.8e-08.
