We're dividing 555205 by 51 
The aim is to understand the frequency of 51 in 555205.

Step 1:
51 goes into 5 0 times with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Grab the next digit (5) from the dividend, add it to 5, then carry on: 55 / 51

Let's proceed to step 2:
55 divided by 51 is 1 with a remainder of 4.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 51 from 55 and we're left with 4.
Take the next digit (5) from the dividend and append it to 4, then repeat: 45 / 51

Moving on to step 3:
The number 51 fits into 45 0 times, leaving a remainder of 45.
Use 0 as the next digit of our solution. 
Result so far: 10.0
If we take 0 away from 45, we end up with 45.
Take the next digit (2) from the dividend and append it to 45, then repeat: 452 / 51

Going ahead to step 4:
452 divided by 51 is 8 with a remainder of 44.
Put 8 as the next digit of the answer. 
Result so far: 108.0
Subtract 408 from 452 to get 44.
Fetch the next digit (0) from the dividend, attach it to 44 and continue: 440 / 51

Going ahead to step 5:
51 can be fit into 440 8 times, resulting in a remainder of 32.
Use 8 as the next digit of our solution. 
Result so far: 1088.0
If we take 408 away from 440, we end up with 32.
Bring next digit (5) of the dividend behind the 32 and repeat the process: 325 / 51

Step 6:
If we divide 325 by 51, we get 6 and a remainder of 19.
The number 6 becomes the next digit in our result. 
Result so far: 10886.0
If we take 306 away from 325, we end up with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Step 7:
When dividing 190 by 51, we get 3 with a remainder of 37.
The next digit of our result is 3. 
Result so far: 10886.3
If we subtract 153 from 190, we get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Let's proceed to step 8:
51 goes into 370 7 times with a remainder of 13.
Record the quotient 7 as the next digit in the result. 
Result so far: 10886.37
If we subtract 357 from 370, we get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Let's proceed to step 9:
The number 51 fits into 130 2 times, leaving a remainder of 28.
Use 2 as the next digit of our solution. 
Result so far: 10886.372
If we subtract 102 from 130, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 10:
If we divide 280 by 51, we get 5 and a remainder of 25.
Write down 5 as next digit of the result. 
Result so far: 10886.3725
Subtract 255 from 280 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Let's proceed to step 11:
51 goes into 250 4 times with a remainder of 46.
The number 4 becomes the next digit in our result. 
Result so far: 10886.37254
The remainder is 46 after subtracting 204 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Advancing to step 12:
The number 51 fits into 460 9 times, leaving a remainder of 1.
Write down 9 as next digit of the result. 
Result so far: 10886.372549
Deduct 459 from 460 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 13:
10 divided by 51 is 0 with a remainder of 10.
The next digit of our result is 0. 
Result so far: 10886.372549
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 14:
100 divided by 51 is 1 with a remainder of 49.
The next digit of our result is 1. 
Result so far: 10886.37254901
If we take 51 away from 100, we end up with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

The final outcome is 10886.37254901, with a leftover of 4.9e-08.
