We look at the division of 619536 by 51 
The aim is to understand the frequency of 51 in 619536.

Let's proceed to step 1:
51 can be fit into 6 0 times, resulting in a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Fetch the next digit (1) from the dividend, attach it to 6 and continue: 61 / 51

Advancing to step 2:
51 goes into 61 1 times with a remainder of 10.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 51 from 61 leaves us with 10.
Bring next digit (9) of the dividend behind the 10 and repeat the process: 109 / 51

Let's proceed to step 3:
51 can be fit into 109 2 times, resulting in a remainder of 7.
Write down 2 as next digit of the result. 
Result so far: 12.0
If we take 102 away from 109, we end up with 7.
Grab the next digit (5) from the dividend, add it to 7, then carry on: 75 / 51

Going ahead to step 4:
51 goes into 75 1 times with a remainder of 24.
Use 1 as the next digit of our solution. 
Result so far: 121.0
The remainder is 24 after subtracting 51 from 75.
Include the next digit (3) from the dividend after 24, then repeat: 243 / 51

Advancing to step 5:
If we divide 243 by 51, we get 4 and a remainder of 39.
Put 4 as the next digit of the answer. 
Result so far: 1214.0
Subtract 204 from 243 to get 39.
Grab the next digit (6) from the dividend, add it to 39, then carry on: 396 / 51

Let's proceed to step 6:
51 goes into 396 7 times with a remainder of 39.
Use 7 as the next digit of our solution. 
Result so far: 12147.0
Subtract 357 from 396 to get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Advancing to step 7:
The number 51 fits into 390 7 times, leaving a remainder of 33.
Put 7 as the next digit of the answer. 
Result so far: 12147.7
Subtract 357 from 390 to get 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Let's proceed to step 8:
The number 51 fits into 330 6 times, leaving a remainder of 24.
The next digit of our result is 6. 
Result so far: 12147.76
If we subtract 306 from 330, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 9:
51 can be fit into 240 4 times, resulting in a remainder of 36.
Use 4 as the next digit of our solution. 
Result so far: 12147.764
Deduct 204 from 240 and we're left 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 10:
51 goes into 360 7 times with a remainder of 3.
The number 7 becomes the next digit in our result. 
Result so far: 12147.7647
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.

Advancing to step 11:
51 can be fit into 30 0 times, resulting in a remainder of 30.
The next digit of our result is 0. 
Result so far: 12147.7647
Subtract 0 from 30 to 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.

Moving on to step 12:
The number 51 fits into 300 5 times, leaving a remainder of 45.
Record the quotient 5 as the next digit in the result. 
Result so far: 12147.764705
Deduct 255 from 300 and we're left with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

On to step 13:
51 goes into 450 8 times with a remainder of 42.
Write down 8 as next digit of the result. 
Result so far: 12147.7647058
Deduct 408 from 450 and we're left 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.

Let's proceed to step 14:
When dividing 420 by 51, we get 8 with a remainder of 12.
The number 8 becomes the next digit in our result. 
Result so far: 12147.76470588
The remainder is 12 after subtracting 408 from 420.
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 outcome is 12147.76470588, with a leftover of 1.2e-08.
