887485 ÷ 51 
The aim is to understand the frequency of 51 in 887485.

Let's proceed to step 1:
When dividing 8 by 51, we get 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Fetch the next digit (8) from the dividend, attach it to 8 and continue: 88 / 51

On to step 2:
The number 51 fits into 88 1 times, leaving a remainder of 37.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 37 after subtracting 51 from 88.
Grab the next digit (7) from the dividend, add it to 37, then carry on: 377 / 51

On to step 3:
377 divided by 51 is 7 with a remainder of 20.
Write down 7 as next digit of the result. 
Result so far: 17.0
Subtracting 357 from 377 leaves us with 20.
Take the next digit (4) from the dividend and append it to 20, then repeat: 204 / 51

On to step 4:
51 can be fit into 204 4 times, resulting in a remainder of 0.
Record the quotient 4 as the next digit in the result. 
Result so far: 174.0
Subtracting 204 from 204 leaves us with 0.
Include the next digit (8) from the dividend after 0, then repeat: 8 / 51

Advancing to step 5:
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: 1740.0
The remainder is 8 after subtracting 0 from 8.
Bring next digit (5) of the dividend behind the 8 and repeat the process: 85 / 51

Going ahead to step 6:
If we divide 85 by 51, we get 1 and a remainder of 34.
Write down 1 as next digit of the result. 
Result so far: 17401.0
If we subtract 51 from 85, we get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

On to step 7:
51 can be fit into 340 6 times, resulting in a remainder of 34.
Use 6 as the next digit of our solution. 
Result so far: 17401.6
The remainder is 34 after subtracting 306 from 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Advancing to step 8:
When dividing 340 by 51, we get 6 with a remainder of 34.
The next digit of our result is 6. 
Result so far: 17401.66
Subtracting 306 from 340 leaves us with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

In conclusion, the division gives 17401.66 with a balance of 0.034.
