We look at the division of 4712163 by 639 
We want to figure out the number of times 4712163 can be divided by 639.

Let's proceed to step 1:
639 can be fit into 4 0 times, resulting in a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Include the next digit (7) from the dividend after 4, then repeat: 47 / 639

Going ahead to step 2:
639 goes into 47 0 times with a remainder of 47.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 47 to get 47.
Include the next digit (1) from the dividend after 47, then repeat: 471 / 639

Step 3:
471 divided by 639 is 0 with a remainder of 471.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 471 and we're left with 471.
Grab the next digit (2) from the dividend, add it to 471, then carry on: 4712 / 639

Let's proceed to step 4:
The number 639 fits into 4712 7 times, leaving a remainder of 239.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
Subtracting 4473 from 4712 leaves us with 239.
Grab the next digit (1) from the dividend, add it to 239, then carry on: 2391 / 639

Step 5:
2391 divided by 639 is 3 with a remainder of 474.
The next digit of our result is 3. 
Result so far: 73.0
Subtract 1917 from 2391 to get 474.
Fetch the next digit (6) from the dividend, attach it to 474 and continue: 4746 / 639

Let's proceed to step 6:
When dividing 4746 by 639, we get 7 with a remainder of 273.
Record the quotient 7 as the next digit in the result. 
Result so far: 737.0
Subtracting 4473 from 4746 leaves us with 273.
Bring next digit (3) of the dividend behind the 273 and repeat the process: 2733 / 639

Going ahead to step 7:
639 goes into 2733 4 times with a remainder of 177.
Put 4 as the next digit of the answer. 
Result so far: 7374.0
The remainder is 177 after subtracting 2556 from 2733.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1770, and continue the process.

Step 8:
639 goes into 1770 2 times with a remainder of 492.
The number 2 becomes the next digit in our result. 
Result so far: 7374.2
The remainder is 492 after subtracting 1278 from 1770.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4920, and continue the process.

Step 9:
If we divide 4920 by 639, we get 7 and a remainder of 447.
The next digit of our result is 7. 
Result so far: 7374.27
If we take 4473 away from 4920, we end up with 447.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4470, and continue the process.

Advancing to step 10:
When dividing 4470 by 639, we get 6 with a remainder of 636.
The next digit of our result is 6. 
Result so far: 7374.276
Subtract 3834 from 4470 to get 636.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6360, and continue the process.

Step 11:
When dividing 6360 by 639, we get 9 with a remainder of 609.
Use 9 as the next digit of our solution. 
Result so far: 7374.2769
The remainder is 609 after subtracting 5751 from 6360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6090, and continue the process.

On to step 12:
The number 639 fits into 6090 9 times, leaving a remainder of 339.
Put 9 as the next digit of the answer. 
Result so far: 7374.27699
If we subtract 5751 from 6090, we get 339.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3390, and continue the process.

In conclusion, the division gives 7374.27699 with a balance of 0.000339.
