769967 ÷ 51 
The aim is to understand the frequency of 51 in 769967.

Going ahead to step 1:
The number 51 fits into 7 0 times, leaving a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Take the next digit (6) from the dividend and append it to 7, then repeat: 76 / 51

Moving on to step 2:
When dividing 76 by 51, we get 1 with a remainder of 25.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 51 from 76 to get 25.
Fetch the next digit (9) from the dividend, attach it to 25 and continue: 259 / 51

Step 3:
259 divided by 51 is 5 with a remainder of 4.
Use 5 as the next digit of our solution. 
Result so far: 15.0
Subtract 255 from 259 to get 4.
Take the next digit (9) from the dividend and append it to 4, then repeat: 49 / 51

Moving on to step 4:
51 can be fit into 49 0 times, resulting in a remainder of 49.
Use 0 as the next digit of our solution. 
Result so far: 150.0
Deduct 0 from 49 and we're left with 49.
Include the next digit (6) from the dividend after 49, then repeat: 496 / 51

Advancing to step 5:
The number 51 fits into 496 9 times, leaving a remainder of 37.
Record the quotient 9 as the next digit in the result. 
Result so far: 1509.0
If we take 459 away from 496, we end up with 37.
Take the next digit (7) from the dividend and append it to 37, then repeat: 377 / 51

Advancing to step 6:
51 goes into 377 7 times with a remainder of 20.
The number 7 becomes the next digit in our result. 
Result so far: 15097.0
Subtracting 357 from 377 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 7:
51 goes into 200 3 times with a remainder of 47.
The number 3 becomes the next digit in our result. 
Result so far: 15097.3
The remainder is 47 after subtracting 153 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Step 8:
470 divided by 51 is 9 with a remainder of 11.
Use 9 as the next digit of our solution. 
Result so far: 15097.39
If we subtract 459 from 470, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 9:
51 can be fit into 110 2 times, resulting in a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 15097.392
The remainder is 8 after subtracting 102 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 10:
When dividing 80 by 51, we get 1 with a remainder of 29.
The number 1 becomes the next digit in our result. 
Result so far: 15097.3921
The remainder is 29 after subtracting 51 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Going ahead to step 11:
290 divided by 51 is 5 with a remainder of 35.
Use 5 as the next digit of our solution. 
Result so far: 15097.39215
If we take 255 away from 290, we end up with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

On to step 12:
350 divided by 51 is 6 with a remainder of 44.
Record the quotient 6 as the next digit in the result. 
Result so far: 15097.392156
If we subtract 306 from 350, we get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

On to step 13:
51 goes into 440 8 times with a remainder of 32.
The next digit of our result is 8. 
Result so far: 15097.3921568
Subtracting 408 from 440 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 14:
The number 51 fits into 320 6 times, leaving a remainder of 14.
The number 6 becomes the next digit in our result. 
Result so far: 15097.39215686
The remainder is 14 after subtracting 306 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

After the division, we end up with 15097.39215686 and a remainder of 1.4e-08.
