We look at the division of 639323 by 76 
Our goal is to divide 639323 by 76.

Step 1:
If we divide 6 by 76, we get 0 and a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Grab the next digit (3) from the dividend, add it to 6, then carry on: 63 / 76

Moving on to step 2:
76 goes into 63 0 times with a remainder of 63.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 63 to get 63.
Grab the next digit (9) from the dividend, add it to 63, then carry on: 639 / 76

Going ahead to step 3:
The number 76 fits into 639 8 times, leaving a remainder of 31.
The next digit of our result is 8. 
Result so far: 8.0
Subtracting 608 from 639 leaves us with 31.
Include the next digit (3) from the dividend after 31, then repeat: 313 / 76

On to step 4:
If we divide 313 by 76, we get 4 and a remainder of 9.
Put 4 as the next digit of the answer. 
Result so far: 84.0
Subtracting 304 from 313 leaves us with 9.
Append the next digit (2) from the dividend to 9 and continue with: 92 / 76

On to step 5:
76 can be fit into 92 1 times, resulting in a remainder of 16.
The number 1 becomes the next digit in our result. 
Result so far: 841.0
If we subtract 76 from 92, we get 16.
Grab the next digit (3) from the dividend, add it to 16, then carry on: 163 / 76

Going ahead to step 6:
If we divide 163 by 76, we get 2 and a remainder of 11.
The next digit of our result is 2. 
Result so far: 8412.0
If we take 152 away from 163, we end up with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 7:
The number 76 fits into 110 1 times, leaving a remainder of 34.
Write down 1 as next digit of the result. 
Result so far: 8412.1
If we subtract 76 from 110, we get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Let's proceed to step 8:
340 divided by 76 is 4 with a remainder of 36.
The number 4 becomes the next digit in our result. 
Result so far: 8412.14
If we take 304 away from 340, 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.

Moving on to step 9:
When dividing 360 by 76, we get 4 with a remainder of 56.
Write down 4 as next digit of the result. 
Result so far: 8412.144
If we take 304 away from 360, we end up with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

After the division, we end up with 8412.144 and a remainder of 0.0056.
