We're dividing 619842 by 51 
The aim is to understand the frequency of 51 in 619842.

Step 1:
The number 51 fits into 6 0 times, leaving a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Grab the next digit (1) from the dividend, add it to 6, then carry on: 61 / 51

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.
Include the next digit (9) from the dividend after 10, then repeat: 109 / 51

Going ahead to step 3:
51 can be fit into 109 2 times, resulting in a remainder of 7.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
Subtracting 102 from 109 leaves us with 7.
Fetch the next digit (8) from the dividend, attach it to 7 and continue: 78 / 51

Moving on to step 4:
51 can be fit into 78 1 times, resulting in a remainder of 27.
Write down 1 as next digit of the result. 
Result so far: 121.0
The remainder is 27 after subtracting 51 from 78.
Append the next digit (4) from the dividend to 27 and continue with: 274 / 51

Let's proceed to step 5:
274 divided by 51 is 5 with a remainder of 19.
The number 5 becomes the next digit in our result. 
Result so far: 1215.0
Subtract 255 from 274 to get 19.
Bring next digit (2) of the dividend behind the 19 and repeat the process: 192 / 51

Going ahead to step 6:
51 goes into 192 3 times with a remainder of 39.
Record the quotient 3 as the next digit in the result. 
Result so far: 12153.0
Subtract 153 from 192 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:
If we divide 390 by 51, we get 7 and a remainder of 33.
Write down 7 as next digit of the result. 
Result so far: 12153.7
If we subtract 357 from 390, we 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:
51 can be fit into 330 6 times, resulting in a remainder of 24.
Write down 6 as next digit of the result. 
Result so far: 12153.76
If we take 306 away from 330, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 9:
The number 51 fits into 240 4 times, leaving a remainder of 36.
Use 4 as the next digit of our solution. 
Result so far: 12153.764
If we take 204 away from 240, 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.

On to step 10:
The number 51 fits into 360 7 times, leaving a remainder of 3.
The number 7 becomes the next digit in our result. 
Result so far: 12153.7647
If we take 357 away from 360, we end up with 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 11:
The number 51 fits into 30 0 times, leaving a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 12153.7647
If we take 0 away from 30, we end up with 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:
If we divide 300 by 51, we get 5 and a remainder of 45.
The number 5 becomes the next digit in our result. 
Result so far: 12153.764705
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.

Step 13:
If we divide 450 by 51, we get 8 and a remainder of 42.
The next digit of our result is 8. 
Result so far: 12153.7647058
Subtract 408 from 450 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

On to step 14:
420 divided by 51 is 8 with a remainder of 12.
Use 8 as the next digit of our solution. 
Result so far: 12153.76470588
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.

After the division, we end up with 12153.76470588 and a remainder of 1.2e-08.
