We're dividing 782177 by 51 
The aim is to understand the frequency of 51 in 782177.

Going ahead to step 1:
When dividing 7 by 51, we get 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Grab the next digit (8) from the dividend, add it to 7, then carry on: 78 / 51

Moving on to step 2:
The number 51 fits into 78 1 times, leaving a remainder of 27.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 51 from 78 to get 27.
Take the next digit (2) from the dividend and append it to 27, then repeat: 272 / 51

Advancing to step 3:
The number 51 fits into 272 5 times, leaving a remainder of 17.
Record the quotient 5 as the next digit in the result. 
Result so far: 15.0
If we subtract 255 from 272, we get 17.
Grab the next digit (1) from the dividend, add it to 17, then carry on: 171 / 51

Step 4:
51 can be fit into 171 3 times, resulting in a remainder of 18.
Use 3 as the next digit of our solution. 
Result so far: 153.0
If we subtract 153 from 171, we get 18.
Take the next digit (7) from the dividend and append it to 18, then repeat: 187 / 51

Going ahead to step 5:
When dividing 187 by 51, we get 3 with a remainder of 34.
The next digit of our result is 3. 
Result so far: 1533.0
Deduct 153 from 187 and we're left with 34.
Grab the next digit (7) from the dividend, add it to 34, then carry on: 347 / 51

Going ahead to step 6:
When dividing 347 by 51, we get 6 with a remainder of 41.
The number 6 becomes the next digit in our result. 
Result so far: 15336.0
The remainder is 41 after subtracting 306 from 347.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Moving on to step 7:
The number 51 fits into 410 8 times, leaving a remainder of 2.
Write down 8 as next digit of the result. 
Result so far: 15336.8
Subtracting 408 from 410 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 8:
51 can be fit into 20 0 times, resulting in a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 15336.8
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 9:
51 goes into 200 3 times with a remainder of 47.
Put 3 as the next digit of the answer. 
Result so far: 15336.803
Deduct 153 from 200 and we're left with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Advancing to step 10:
470 divided by 51 is 9 with a remainder of 11.
Record the quotient 9 as the next digit in the result. 
Result so far: 15336.8039
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.

Going ahead to step 11:
When dividing 110 by 51, we get 2 with a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 15336.80392
Subtract 102 from 110 to get 8.
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 12:
51 can be fit into 80 1 times, resulting in a remainder of 29.
The next digit of our result is 1. 
Result so far: 15336.803921
Subtracting 51 from 80 leaves us with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Advancing to step 13:
When dividing 290 by 51, we get 5 with a remainder of 35.
The number 5 becomes the next digit in our result. 
Result so far: 15336.8039215
If we subtract 255 from 290, we get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Going ahead to step 14:
When dividing 350 by 51, we get 6 with a remainder of 44.
The number 6 becomes the next digit in our result. 
Result so far: 15336.80392156
If we take 306 away from 350, we end up with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

After the division, we end up with 15336.80392156 and a remainder of 4.4e-08.
