We look at the division of 587172 by 84 
We want to divide 587172 by 84.

Advancing to step 1:
5 divided by 84 is 0 with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Include the next digit (8) from the dividend after 5, then repeat: 58 / 84

Advancing to step 2:
58 divided by 84 is 0 with a remainder of 58.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 58, we end up with 58.
Bring next digit (7) of the dividend behind the 58 and repeat the process: 587 / 84

Going ahead to step 3:
The number 84 fits into 587 6 times, leaving a remainder of 83.
Use 6 as the next digit of our solution. 
Result so far: 6.0
Subtract 504 from 587 to get 83.
Bring next digit (1) of the dividend behind the 83 and repeat the process: 831 / 84

Let's proceed to step 4:
When dividing 831 by 84, we get 9 with a remainder of 75.
The next digit of our result is 9. 
Result so far: 69.0
If we take 756 away from 831, we end up with 75.
Fetch the next digit (7) from the dividend, attach it to 75 and continue: 757 / 84

Let's proceed to step 5:
84 goes into 757 9 times with a remainder of 1.
Put 9 as the next digit of the answer. 
Result so far: 699.0
Subtract 756 from 757 to get 1.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 84

Step 6:
12 divided by 84 is 0 with a remainder of 12.
Record the quotient 0 as the next digit in the result. 
Result so far: 6990.0
If we take 0 away from 12, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 7:
84 goes into 120 1 times with a remainder of 36.
Use 1 as the next digit of our solution. 
Result so far: 6990.1
If we take 84 away from 120, we end up with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

On to step 8:
84 goes into 360 4 times with a remainder of 24.
Write down 4 as next digit of the result. 
Result so far: 6990.14
If we take 336 away from 360, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 9:
240 divided by 84 is 2 with a remainder of 72.
Put 2 as the next digit of the answer. 
Result so far: 6990.142
The remainder is 72 after subtracting 168 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Let's proceed to step 10:
720 divided by 84 is 8 with a remainder of 48.
The number 8 becomes the next digit in our result. 
Result so far: 6990.1428
The remainder is 48 after subtracting 672 from 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Going ahead to step 11:
When dividing 480 by 84, we get 5 with a remainder of 60.
The next digit of our result is 5. 
Result so far: 6990.14285
Deduct 420 from 480 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 12:
84 can be fit into 600 7 times, resulting in a remainder of 12.
The number 7 becomes the next digit in our result. 
Result so far: 6990.142857
The remainder is 12 after subtracting 588 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 13:
84 goes into 120 1 times with a remainder of 36.
The number 1 becomes the next digit in our result. 
Result so far: 6990.1428571
If we subtract 84 from 120, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

On to step 14:
If we divide 360 by 84, we get 4 and a remainder of 24.
The next digit of our result is 4. 
Result so far: 6990.14285714
Subtract 336 from 360 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

The final result is 6990.14285714 with a remainder of 2.4e-08.
