We look at the division of 610353 by 51 
The aim is to understand the frequency of 51 in 610353.

Step 1:
51 can be fit into 6 0 times, resulting in a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Bring next digit (1) of the dividend behind the 6 and repeat the process: 61 / 51

On to step 2:
If we divide 61 by 51, we get 1 and a remainder of 10.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 51 from 61 leaves us with 10.
Fetch the next digit (0) from the dividend, attach it to 10 and continue: 100 / 51

Moving on to step 3:
51 goes into 100 1 times with a remainder of 49.
The next digit of our result is 1. 
Result so far: 11.0
Deduct 51 from 100 and we're left with 49.
Fetch the next digit (3) from the dividend, attach it to 49 and continue: 493 / 51

Moving on to step 4:
The number 51 fits into 493 9 times, leaving a remainder of 34.
The next digit of our result is 9. 
Result so far: 119.0
Subtracting 459 from 493 leaves us with 34.
Bring next digit (5) of the dividend behind the 34 and repeat the process: 345 / 51

Advancing to step 5:
51 goes into 345 6 times with a remainder of 39.
Record the quotient 6 as the next digit in the result. 
Result so far: 1196.0
If we take 306 away from 345, we end up with 39.
Bring next digit (3) of the dividend behind the 39 and repeat the process: 393 / 51

Going ahead to step 6:
The number 51 fits into 393 7 times, leaving a remainder of 36.
Write down 7 as next digit of the result. 
Result so far: 11967.0
If we take 357 away from 393, we end up with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 7:
The number 51 fits into 360 7 times, leaving a remainder of 3.
The next digit of our result is 7. 
Result so far: 11967.7
Subtract 357 from 360 to get 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:
51 goes into 30 0 times with a remainder of 30.
The next digit of our result is 0. 
Result so far: 11967.7
If we subtract 0 from 30, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 9:
51 can be fit into 300 5 times, resulting in a remainder of 45.
Write down 5 as next digit of the result. 
Result so far: 11967.705
If we subtract 255 from 300, we get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Advancing to step 10:
450 divided by 51 is 8 with a remainder of 42.
Use 8 as the next digit of our solution. 
Result so far: 11967.7058
Subtracting 408 from 450 leaves us 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.

Going ahead to step 11:
If we divide 420 by 51, we get 8 and a remainder of 12.
Write down 8 as next digit of the result. 
Result so far: 11967.70588
If we take 408 away from 420, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

The final result is 11967.70588 with a remainder of 1.2e-05.
