619794 ÷ 51 
The aim is to understand the frequency of 51 in 619794.

Moving on to step 1:
When dividing 6 by 51, we get 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
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

Advancing to step 2:
The number 51 fits into 61 1 times, leaving a remainder of 10.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 51 away from 61, we end up with 10.
Append the next digit (9) from the dividend to 10 and continue with: 109 / 51

Step 3:
51 goes into 109 2 times with a remainder of 7.
Put 2 as the next digit of the answer. 
Result so far: 12.0
Subtract 102 from 109 to get 7.
Take the next digit (7) from the dividend and append it to 7, then repeat: 77 / 51

Step 4:
The number 51 fits into 77 1 times, leaving a remainder of 26.
Use 1 as the next digit of our solution. 
Result so far: 121.0
If we take 51 away from 77, we end up with 26.
Include the next digit (9) from the dividend after 26, then repeat: 269 / 51

On to step 5:
269 divided by 51 is 5 with a remainder of 14.
The next digit of our result is 5. 
Result so far: 1215.0
If we subtract 255 from 269, we get 14.
Fetch the next digit (4) from the dividend, attach it to 14 and continue: 144 / 51

Step 6:
When dividing 144 by 51, we get 2 with a remainder of 42.
The next digit of our result is 2. 
Result so far: 12152.0
The remainder is 42 after subtracting 102 from 144.
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 7:
When dividing 420 by 51, we get 8 with a remainder of 12.
Write down 8 as next digit of the result. 
Result so far: 12152.8
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.

Going ahead to step 8:
If we divide 120 by 51, we get 2 and a remainder of 18.
Write down 2 as next digit of the result. 
Result so far: 12152.82
If we take 102 away from 120, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 9:
180 divided by 51 is 3 with a remainder of 27.
Write down 3 as next digit of the result. 
Result so far: 12152.823
If we take 153 away from 180, we end up with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Let's proceed to step 10:
If we divide 270 by 51, we get 5 and a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 12152.8235
Deduct 255 from 270 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 11:
51 goes into 150 2 times with a remainder of 48.
Write down 2 as next digit of the result. 
Result so far: 12152.82352
Deduct 102 from 150 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Step 12:
If we divide 480 by 51, we get 9 and a remainder of 21.
Write down 9 as next digit of the result. 
Result so far: 12152.823529
Deduct 459 from 480 and we're left with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Advancing to step 13:
51 goes into 210 4 times with a remainder of 6.
Use 4 as the next digit of our solution. 
Result so far: 12152.8235294
If we subtract 204 from 210, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 14:
The number 51 fits into 60 1 times, leaving a remainder of 9.
Use 1 as the next digit of our solution. 
Result so far: 12152.82352941
Deduct 51 from 60 and we're left with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

In conclusion, the division gives 12152.82352941 with a balance of 9e-09.
