887828 ÷ 51 
The aim is to understand the frequency of 51 in 887828.

Advancing to step 1:
When dividing 8 by 51, we get 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Append the next digit (8) from the dividend to 8 and continue with: 88 / 51

Step 2:
51 can be fit into 88 1 times, resulting in a remainder of 37.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 51 from 88 leaves us with 37.
Take the next digit (7) from the dividend and append it to 37, then repeat: 377 / 51

Advancing to step 3:
51 can be fit into 377 7 times, resulting in a remainder of 20.
Use 7 as the next digit of our solution. 
Result so far: 17.0
Subtract 357 from 377 to get 20.
Append the next digit (8) from the dividend to 20 and continue with: 208 / 51

Advancing to step 4:
If we divide 208 by 51, we get 4 and a remainder of 4.
Use 4 as the next digit of our solution. 
Result so far: 174.0
If we take 204 away from 208, we end up with 4.
Take the next digit (2) from the dividend and append it to 4, then repeat: 42 / 51

Moving on to step 5:
If we divide 42 by 51, we get 0 and a remainder of 42.
Write down 0 as next digit of the result. 
Result so far: 1740.0
If we take 0 away from 42, we end up with 42.
Append the next digit (8) from the dividend to 42 and continue with: 428 / 51

Step 6:
The number 51 fits into 428 8 times, leaving a remainder of 20.
Write down 8 as next digit of the result. 
Result so far: 17408.0
Subtracting 408 from 428 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.

On to step 7:
51 can be fit into 200 3 times, resulting in a remainder of 47.
Put 3 as the next digit of the answer. 
Result so far: 17408.3
Subtracting 153 from 200 leaves us 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.

Moving on to step 8:
The number 51 fits into 470 9 times, leaving a remainder of 11.
Put 9 as the next digit of the answer. 
Result so far: 17408.39
Deduct 459 from 470 and we're left with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Let's proceed to step 9:
51 goes into 110 2 times with a remainder of 8.
Record the quotient 2 as the next digit in the result. 
Result so far: 17408.392
Deduct 102 from 110 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 10:
51 goes into 80 1 times with a remainder of 29.
Put 1 as the next digit of the answer. 
Result so far: 17408.3921
If we take 51 away from 80, we end up 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.

Let's proceed to step 11:
51 can be fit into 290 5 times, resulting in a remainder of 35.
Use 5 as the next digit of our solution. 
Result so far: 17408.39215
The remainder is 35 after subtracting 255 from 290.
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: 17408.392156
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.

Step 13:
The number 51 fits into 440 8 times, leaving a remainder of 32.
The next digit of our result is 8. 
Result so far: 17408.3921568
Deduct 408 from 440 and we're left 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.

On to step 14:
51 goes into 320 6 times with a remainder of 14.
The next digit of our result is 6. 
Result so far: 17408.39215686
If we subtract 306 from 320, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Our division results in 17408.39215686 with a remaining 1.4e-08.
