We look at the division of 1511 by 84 
We want to divide 1511 by 84.

Step 1:
84 goes into 1 0 times with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Fetch the next digit (5) from the dividend, attach it to 1 and continue: 15 / 84

Let's proceed to step 2:
84 can be fit into 15 0 times, resulting in a remainder of 15.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 15, we get 15.
Append the next digit (1) from the dividend to 15 and continue with: 151 / 84

Going ahead to step 3:
151 divided by 84 is 1 with a remainder of 67.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 84 from 151, we get 67.
Fetch the next digit (1) from the dividend, attach it to 67 and continue: 671 / 84

Going ahead to step 4:
84 goes into 671 7 times with a remainder of 83.
Write down 7 as next digit of the result. 
Result so far: 17.0
If we subtract 588 from 671, we get 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

Advancing to step 5:
The number 84 fits into 830 9 times, leaving a remainder of 74.
Put 9 as the next digit of the answer. 
Result so far: 17.9
If we subtract 756 from 830, we get 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 6:
When dividing 740 by 84, we get 8 with a remainder of 68.
The next digit of our result is 8. 
Result so far: 17.98
Subtracting 672 from 740 leaves us with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

On to step 7:
680 divided by 84 is 8 with a remainder of 8.
The next digit of our result is 8. 
Result so far: 17.988
If we subtract 672 from 680, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

After the division, we end up with 17.988 and a remainder of 0.0008.
