We're dividing 770299 by 84 
Let's see how many times 84 fits into 770299.

On to step 1:
If we divide 7 by 84, we get 0 and a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Append the next digit (7) from the dividend to 7 and continue with: 77 / 84

Advancing to step 2:
When dividing 77 by 84, we get 0 with a remainder of 77.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 77, we get 77.
Take the next digit (0) from the dividend and append it to 77, then repeat: 770 / 84

Going ahead to step 3:
770 divided by 84 is 9 with a remainder of 14.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
If we subtract 756 from 770, we get 14.
Take the next digit (2) from the dividend and append it to 14, then repeat: 142 / 84

Advancing to step 4:
84 goes into 142 1 times with a remainder of 58.
The number 1 becomes the next digit in our result. 
Result so far: 91.0
Subtracting 84 from 142 leaves us with 58.
Take the next digit (9) from the dividend and append it to 58, then repeat: 589 / 84

On to step 5:
589 divided by 84 is 7 with a remainder of 1.
Put 7 as the next digit of the answer. 
Result so far: 917.0
If we take 588 away from 589, we end up with 1.
Take the next digit (9) from the dividend and append it to 1, then repeat: 19 / 84

Let's proceed to step 6:
19 divided by 84 is 0 with a remainder of 19.
Put 0 as the next digit of the answer. 
Result so far: 9170.0
The remainder is 19 after subtracting 0 from 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Let's proceed to step 7:
84 can be fit into 190 2 times, resulting in a remainder of 22.
Write down 2 as next digit of the result. 
Result so far: 9170.2
Subtract 168 from 190 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Going ahead to step 8:
84 goes into 220 2 times with a remainder of 52.
The number 2 becomes the next digit in our result. 
Result so far: 9170.22
Subtracting 168 from 220 leaves us with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

After the division, we end up with 9170.22 and a remainder of 0.052.
