Subtracting 0 from 7 leaves us with 7.
Fetch the next digit (6) from the dividend, attach it to 7 and continue: 76 / 84

Advancing to step 2:
If we divide 76 by 84, we get 0 and a remainder of 76.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 76 after subtracting 0 from 76.
Grab the next digit (9) from the dividend, add it to 76, then carry on: 769 / 84

Step 3:
The number 84 fits into 769 9 times, leaving a remainder of 13.
Put 9 as the next digit of the answer. 
Result so far: 9.0
Subtract 756 from 769 to get 13.
Fetch the next digit (0) from the dividend, attach it to 13 and continue: 130 / 84

On to step 4:
The number 84 fits into 130 1 times, leaving a remainder of 46.
The next digit of our result is 1. 
Result so far: 91.0
Subtracting 84 from 130 leaves us with 46.
Take the next digit (4) from the dividend and append it to 46, then repeat: 464 / 84

Step 5:
The number 84 fits into 464 5 times, leaving a remainder of 44.
Put 5 as the next digit of the answer. 
Result so far: 915.0
Subtracting 420 from 464 leaves us with 44.
Take the next digit (8) from the dividend and append it to 44, then repeat: 448 / 84

Moving on to step 6:
When dividing 448 by 84, we get 5 with a remainder of 28.
Write down 5 as next digit of the result. 
Result so far: 9155.0
Subtracting 420 from 448 leaves us 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.

Moving on to step 7:
When dividing 280 by 84, we get 3 with a remainder of 28.
Record the quotient 3 as the next digit in the result. 
Result so far: 9155.3
The remainder is 28 after subtracting 252 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

On to step 8:
The number 84 fits into 280 3 times, leaving a remainder of 28.
The number 3 becomes the next digit in our result. 
Result so far: 9155.33
If we subtract 252 from 280, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.
