5 divided by 639 is 0 with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Include the next digit (7) from the dividend after 5, then repeat: 57 / 639

On to step 2:
57 divided by 639 is 0 with a remainder of 57.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 57 after subtracting 0 from 57.
Fetch the next digit (7) from the dividend, attach it to 57 and continue: 577 / 639

Moving on to step 3:
577 divided by 639 is 0 with a remainder of 577.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 577 leaves us with 577.
Grab the next digit (2) from the dividend, add it to 577, then carry on: 5772 / 639

On to step 4:
When dividing 5772 by 639, we get 9 with a remainder of 21.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
If we take 5751 away from 5772, we end up with 21.
Grab the next digit (9) from the dividend, add it to 21, then carry on: 219 / 639

Moving on to step 5:
639 goes into 219 0 times with a remainder of 219.
The next digit of our result is 0. 
Result so far: 90.0
Subtracting 0 from 219 leaves us with 219.
Grab the next digit (6) from the dividend, add it to 219, then carry on: 2196 / 639

On to step 6:
If we divide 2196 by 639, we get 3 and a remainder of 279.
The number 3 becomes the next digit in our result. 
Result so far: 903.0
The remainder is 279 after subtracting 1917 from 2196.
Fetch the next digit (3) from the dividend, attach it to 279 and continue: 2793 / 639

Let's proceed to step 7:
If we divide 2793 by 639, we get 4 and a remainder of 237.
Record the quotient 4 as the next digit in the result. 
Result so far: 9034.0
If we take 2556 away from 2793, we end up with 237.
Take the next digit (6) from the dividend and append it to 237, then repeat: 2376 / 639

On to step 8:
When dividing 2376 by 639, we get 3 with a remainder of 459.
The number 3 becomes the next digit in our result. 
Result so far: 90343.0
If we subtract 1917 from 2376, we get 459.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4590, and continue the process.

Step 9:
4590 divided by 639 is 7 with a remainder of 117.
Use 7 as the next digit of our solution. 
Result so far: 90343.7
Subtract 4473 from 4590 to get 117.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1170, and continue the process.

Advancing to step 10:
1170 divided by 639 is 1 with a remainder of 531.
Record the quotient 1 as the next digit in the result. 
Result so far: 90343.71
The remainder is 531 after subtracting 639 from 1170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5310, and continue the process.

Let's proceed to step 11:
639 goes into 5310 8 times with a remainder of 198.
Write down 8 as next digit of the result. 
Result so far: 90343.718
Subtracting 5112 from 5310 leaves us with 198.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1980, and continue the process.

Moving on to step 12:
If we divide 1980 by 639, we get 3 and a remainder of 63.
Use 3 as the next digit of our solution. 
Result so far: 90343.7183
Deduct 1917 from 1980 and we're left with 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Moving on to step 13:
639 goes into 630 0 times with a remainder of 630.
The next digit of our result is 0. 
Result so far: 90343.7183
If we subtract 0 from 630, we get 630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6300, and continue the process.

Advancing to step 14:
The number 639 fits into 6300 9 times, leaving a remainder of 549.
The number 9 becomes the next digit in our result. 
Result so far: 90343.718309
Subtract 5751 from 6300 to get 549.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5490, and continue the process.

On to step 15:
639 goes into 5490 8 times with a remainder of 378.
The number 8 becomes the next digit in our result. 
Result so far: 90343.7183098
Deduct 5112 from 5490 and we're left with 378.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3780, and continue the process.

Going ahead to step 16:
The number 639 fits into 3780 5 times, leaving a remainder of 585.
Put 5 as the next digit of the answer. 
Result so far: 90343.71830985
If we take 3195 away from 3780, we end up with 585.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5850, and continue the process.

Our division results in 90343.71830985 with a remaining 5.85e-07.
