We divide 888790 by 84
The aim is to understand the frequency of 84 in 888790.

Let's proceed to step 1:
If we divide 8 by 84, we get 0 and a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Grab the next digit (8) from the dividend, add it to 8, then carry on: 88 / 84

On to step 2:
When dividing 88 by 84, we get 1 with a remainder of 4.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 4 after subtracting 84 from 88.
Fetch the next digit (8) from the dividend, attach it to 4 and continue: 48 / 84

On to step 3:
If we divide 48 by 84, we get 0 and a remainder of 48.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
Subtract 0 from 48 to get 48.
Grab the next digit (7) from the dividend, add it to 48, then carry on: 487 / 84

Going ahead to step 4:
The number 84 fits into 487 5 times, leaving a remainder of 67.
Use 5 as the next digit of our solution. 
Result so far: 105.0
If we subtract 420 from 487, we get 67.
Bring next digit (9) of the dividend behind the 67 and repeat the process: 679 / 84

Let's proceed to step 5:
The number 84 fits into 679 8 times, leaving a remainder of 7.
The next digit of our result is 8. 
Result so far: 1058.0
Deduct 672 from 679 and we're left with 7.
Include the next digit (0) from the dividend after 7, then repeat: 70 / 84

Step 6:
84 can be fit into 70 0 times, resulting in a remainder of 70.
Write down 0 as next digit of the result. 
Result so far: 10580.0
If we subtract 0 from 70, we get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

On to step 7:
84 can be fit into 700 8 times, resulting in a remainder of 28.
The number 8 becomes the next digit in our result. 
Result so far: 10580.8
The remainder is 28 after subtracting 672 from 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Advancing to step 8:
280 divided by 84 is 3 with a remainder of 28.
Write down 3 as next digit of the result. 
Result so far: 10580.83
If we take 252 away from 280, we end up with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 9:
84 can be fit into 280 3 times, resulting in a remainder of 28.
The number 3 becomes the next digit in our result. 
Result so far: 10580.833
If we take 252 away from 280, we end up with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

After the division, we end up with 10580.833 and a remainder of 0.0028.
