We look at the division of 639502 by 84 
Our goal is to divide 639502 by 84.

Going ahead to step 1:
6 divided by 84 is 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Include the next digit (3) from the dividend after 6, then repeat: 63 / 84

On to step 2:
If we divide 63 by 84, we get 0 and a remainder of 63.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 63 leaves us with 63.
Grab the next digit (9) from the dividend, add it to 63, then carry on: 639 / 84

Step 3:
84 goes into 639 7 times with a remainder of 51.
Use 7 as the next digit of our solution. 
Result so far: 7.0
Subtracting 588 from 639 leaves us with 51.
Include the next digit (5) from the dividend after 51, then repeat: 515 / 84

Going ahead to step 4:
84 can be fit into 515 6 times, resulting in a remainder of 11.
Write down 6 as next digit of the result. 
Result so far: 76.0
The remainder is 11 after subtracting 504 from 515.
Grab the next digit (0) from the dividend, add it to 11, then carry on: 110 / 84

Moving on to step 5:
84 can be fit into 110 1 times, resulting in a remainder of 26.
The next digit of our result is 1. 
Result so far: 761.0
If we subtract 84 from 110, we get 26.
Append the next digit (2) from the dividend to 26 and continue with: 262 / 84

On to step 6:
84 goes into 262 3 times with a remainder of 10.
The number 3 becomes the next digit in our result. 
Result so far: 7613.0
Subtract 252 from 262 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 7:
100 divided by 84 is 1 with a remainder of 16.
Use 1 as the next digit of our solution. 
Result so far: 7613.1
If we subtract 84 from 100, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 8:
84 can be fit into 160 1 times, resulting in a remainder of 76.
Use 1 as the next digit of our solution. 
Result so far: 7613.11
The remainder is 76 after subtracting 84 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

The final outcome is 7613.11, with a leftover of 0.076.
