888299 ÷ 84 
The aim is to understand the frequency of 84 in 888299.

Going ahead to step 1:
When dividing 8 by 84, we get 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Bring next digit (8) of the dividend behind the 8 and repeat the process: 88 / 84

Let's proceed to step 2:
The number 84 fits into 88 1 times, leaving a remainder of 4.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 84 from 88 leaves us with 4.
Append the next digit (8) from the dividend to 4 and continue with: 48 / 84

Let's proceed to step 3:
If we divide 48 by 84, we get 0 and a remainder of 48.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
The remainder is 48 after subtracting 0 from 48.
Append the next digit (2) from the dividend to 48 and continue with: 482 / 84

Going ahead to step 4:
The number 84 fits into 482 5 times, leaving a remainder of 62.
Record the quotient 5 as the next digit in the result. 
Result so far: 105.0
Subtract 420 from 482 to get 62.
Bring next digit (9) of the dividend behind the 62 and repeat the process: 629 / 84

Let's proceed to step 5:
84 can be fit into 629 7 times, resulting in a remainder of 41.
Record the quotient 7 as the next digit in the result. 
Result so far: 1057.0
The remainder is 41 after subtracting 588 from 629.
Bring next digit (9) of the dividend behind the 41 and repeat the process: 419 / 84

Advancing to step 6:
84 can be fit into 419 4 times, resulting in a remainder of 83.
Record the quotient 4 as the next digit in the result. 
Result so far: 10574.0
Deduct 336 from 419 and we're left with 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

Going ahead to step 7:
When dividing 830 by 84, we get 9 with a remainder of 74.
The number 9 becomes the next digit in our result. 
Result so far: 10574.9
Deduct 756 from 830 and we're left with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

On to step 8:
84 can be fit into 740 8 times, resulting in a remainder of 68.
Record the quotient 8 as the next digit in the result. 
Result so far: 10574.98
The remainder is 68 after subtracting 672 from 740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Moving on to step 9:
If we divide 680 by 84, we get 8 and a remainder of 8.
Write down 8 as next digit of the result. 
Result so far: 10574.988
Deduct 672 from 680 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.

Our division results in 10574.988 with a remaining 0.0008.
