Let's divide 88604223 by 639
We're looking to find how many times 639 goes into 88604223.

Advancing to step 1:
When dividing 8 by 639, we get 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Append the next digit (8) from the dividend to 8 and continue with: 88 / 639

Moving on to step 2:
If we divide 88 by 639, we get 0 and a remainder of 88.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 88 leaves us with 88.
Grab the next digit (6) from the dividend, add it to 88, then carry on: 886 / 639

Let's proceed to step 3:
639 can be fit into 886 1 times, resulting in a remainder of 247.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 639 from 886, we get 247.
Fetch the next digit (0) from the dividend, attach it to 247 and continue: 2470 / 639

Going ahead to step 4:
639 goes into 2470 3 times with a remainder of 553.
Put 3 as the next digit of the answer. 
Result so far: 13.0
If we take 1917 away from 2470, we end up with 553.
Include the next digit (4) from the dividend after 553, then repeat: 5534 / 639

Step 5:
When dividing 5534 by 639, we get 8 with a remainder of 422.
Write down 8 as next digit of the result. 
Result so far: 138.0
If we take 5112 away from 5534, we end up with 422.
Take the next digit (2) from the dividend and append it to 422, then repeat: 4222 / 639

Moving on to step 6:
639 can be fit into 4222 6 times, resulting in a remainder of 388.
The next digit of our result is 6. 
Result so far: 1386.0
Deduct 3834 from 4222 and we're left with 388.
Append the next digit (2) from the dividend to 388 and continue with: 3882 / 639

Going ahead to step 7:
When dividing 3882 by 639, we get 6 with a remainder of 48.
The number 6 becomes the next digit in our result. 
Result so far: 13866.0
Subtract 3834 from 3882 to get 48.
Append the next digit (3) from the dividend to 48 and continue with: 483 / 639

Let's proceed to step 8:
639 goes into 483 0 times with a remainder of 483.
Write down 0 as next digit of the result. 
Result so far: 138660.0
Deduct 0 from 483 and we're left with 483.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4830, and continue the process.

Let's proceed to step 9:
639 goes into 4830 7 times with a remainder of 357.
Record the quotient 7 as the next digit in the result. 
Result so far: 138660.7
Subtract 4473 from 4830 to get 357.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3570, and continue the process.

Moving on to step 10:
The number 639 fits into 3570 5 times, leaving a remainder of 375.
Use 5 as the next digit of our solution. 
Result so far: 138660.75
Deduct 3195 from 3570 and we're left with 375.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3750, and continue the process.

Going ahead to step 11:
639 can be fit into 3750 5 times, resulting in a remainder of 555.
Put 5 as the next digit of the answer. 
Result so far: 138660.755
The remainder is 555 after subtracting 3195 from 3750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5550, and continue the process.

After the division, we end up with 138660.755 and a remainder of 0.0555.
