2984079 ÷ 857 
The aim is to understand the frequency of 857 in 2984079.

Step 1:
2 divided by 857 is 0 with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Bring next digit (9) of the dividend behind the 2 and repeat the process: 29 / 857

Advancing to step 2:
29 divided by 857 is 0 with a remainder of 29.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 29 and we're left with 29.
Include the next digit (8) from the dividend after 29, then repeat: 298 / 857

Let's proceed to step 3:
The number 857 fits into 298 0 times, leaving a remainder of 298.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 298, we get 298.
Include the next digit (4) from the dividend after 298, then repeat: 2984 / 857

Moving on to step 4:
2984 divided by 857 is 3 with a remainder of 413.
Write down 3 as next digit of the result. 
Result so far: 3.0
Subtracting 2571 from 2984 leaves us with 413.
Append the next digit (0) from the dividend to 413 and continue with: 4130 / 857

Going ahead to step 5:
If we divide 4130 by 857, we get 4 and a remainder of 702.
The number 4 becomes the next digit in our result. 
Result so far: 34.0
The remainder is 702 after subtracting 3428 from 4130.
Append the next digit (7) from the dividend to 702 and continue with: 7027 / 857

Going ahead to step 6:
If we divide 7027 by 857, we get 8 and a remainder of 171.
Record the quotient 8 as the next digit in the result. 
Result so far: 348.0
Subtract 6856 from 7027 to get 171.
Fetch the next digit (9) from the dividend, attach it to 171 and continue: 1719 / 857

Moving on to step 7:
The number 857 fits into 1719 2 times, leaving a remainder of 5.
Use 2 as the next digit of our solution. 
Result so far: 3482.0
Deduct 1714 from 1719 and we're left 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 8:
If we divide 50 by 857, we get 0 and a remainder of 50.
Use 0 as the next digit of our solution. 
Result so far: 3482.0
Subtract 0 from 50 to 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.

On to step 9:
500 divided by 857 is 0 with a remainder of 500.
Record the quotient 0 as the next digit in the result. 
Result so far: 3482.0
Deduct 0 from 500 and we're left with 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

The quotient of the division is 3482.0, and the remainder is 0.5.
