791849 ÷ 51 
The aim is to understand the frequency of 51 in 791849.

Going ahead to step 1:
51 goes into 7 0 times with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Append the next digit (9) from the dividend to 7 and continue with: 79 / 51

Let's proceed to step 2:
51 goes into 79 1 times with a remainder of 28.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 51 from 79, we get 28.
Fetch the next digit (1) from the dividend, attach it to 28 and continue: 281 / 51

Let's proceed to step 3:
When dividing 281 by 51, we get 5 with a remainder of 26.
The number 5 becomes the next digit in our result. 
Result so far: 15.0
Subtract 255 from 281 to get 26.
Fetch the next digit (8) from the dividend, attach it to 26 and continue: 268 / 51

On to step 4:
51 can be fit into 268 5 times, resulting in a remainder of 13.
The next digit of our result is 5. 
Result so far: 155.0
The remainder is 13 after subtracting 255 from 268.
Bring next digit (4) of the dividend behind the 13 and repeat the process: 134 / 51

Advancing to step 5:
When dividing 134 by 51, we get 2 with a remainder of 32.
The next digit of our result is 2. 
Result so far: 1552.0
The remainder is 32 after subtracting 102 from 134.
Bring next digit (9) of the dividend behind the 32 and repeat the process: 329 / 51

Going ahead to step 6:
329 divided by 51 is 6 with a remainder of 23.
Use 6 as the next digit of our solution. 
Result so far: 15526.0
Deduct 306 from 329 and we're left with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Moving on to step 7:
51 goes into 230 4 times with a remainder of 26.
Write down 4 as next digit of the result. 
Result so far: 15526.4
The remainder is 26 after subtracting 204 from 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Moving on to step 8:
51 can be fit into 260 5 times, resulting in a remainder of 5.
The next digit of our result is 5. 
Result so far: 15526.45
Subtracting 255 from 260 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 9:
The number 51 fits into 50 0 times, leaving a remainder of 50.
Record the quotient 0 as the next digit in the result. 
Result so far: 15526.45
If we subtract 0 from 50, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 10:
The number 51 fits into 500 9 times, leaving a remainder of 41.
Put 9 as the next digit of the answer. 
Result so far: 15526.4509
Deduct 459 from 500 and we're left with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Advancing to step 11:
410 divided by 51 is 8 with a remainder of 2.
Use 8 as the next digit of our solution. 
Result so far: 15526.45098
If we take 408 away from 410, we end up 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.

On to step 12:
51 can be fit into 20 0 times, resulting in a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 15526.45098
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.

Moving on to step 13:
200 divided by 51 is 3 with a remainder of 47.
Use 3 as the next digit of our solution. 
Result so far: 15526.4509803
If we take 153 away from 200, we end up 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.

Going ahead to step 14:
The number 51 fits into 470 9 times, leaving a remainder of 11.
The number 9 becomes the next digit in our result. 
Result so far: 15526.45098039
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.

After the division, we end up with 15526.45098039 and a remainder of 1.1e-08.
