We're dividing 85522788 by 639 
We want to figure out the number of times 85522788 can be divided by 639.

Advancing to step 1:
8 divided by 639 is 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Grab the next digit (5) from the dividend, add it to 8, then carry on: 85 / 639

Moving on to step 2:
639 goes into 85 0 times with a remainder of 85.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 85, we end up with 85.
Append the next digit (5) from the dividend to 85 and continue with: 855 / 639

Step 3:
855 divided by 639 is 1 with a remainder of 216.
The next digit of our result is 1. 
Result so far: 1.0
If we take 639 away from 855, we end up with 216.
Bring next digit (2) of the dividend behind the 216 and repeat the process: 2162 / 639

Let's proceed to step 4:
When dividing 2162 by 639, we get 3 with a remainder of 245.
The next digit of our result is 3. 
Result so far: 13.0
Subtracting 1917 from 2162 leaves us with 245.
Grab the next digit (2) from the dividend, add it to 245, then carry on: 2452 / 639

Let's proceed to step 5:
639 goes into 2452 3 times with a remainder of 535.
Write down 3 as next digit of the result. 
Result so far: 133.0
The remainder is 535 after subtracting 1917 from 2452.
Include the next digit (7) from the dividend after 535, then repeat: 5357 / 639

Advancing to step 6:
639 can be fit into 5357 8 times, resulting in a remainder of 245.
Write down 8 as next digit of the result. 
Result so far: 1338.0
Subtract 5112 from 5357 to get 245.
Take the next digit (8) from the dividend and append it to 245, then repeat: 2458 / 639

Moving on to step 7:
When dividing 2458 by 639, we get 3 with a remainder of 541.
The next digit of our result is 3. 
Result so far: 13383.0
Subtract 1917 from 2458 to get 541.
Take the next digit (8) from the dividend and append it to 541, then repeat: 5418 / 639

Moving on to step 8:
639 goes into 5418 8 times with a remainder of 306.
Record the quotient 8 as the next digit in the result. 
Result so far: 133838.0
Subtract 5112 from 5418 to get 306.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3060, and continue the process.

Going ahead to step 9:
3060 divided by 639 is 4 with a remainder of 504.
The number 4 becomes the next digit in our result. 
Result so far: 133838.4
Subtracting 2556 from 3060 leaves us with 504.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5040, and continue the process.

Advancing to step 10:
The number 639 fits into 5040 7 times, leaving a remainder of 567.
Record the quotient 7 as the next digit in the result. 
Result so far: 133838.47
Subtract 4473 from 5040 to get 567.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5670, and continue the process.

Going ahead to step 11:
If we divide 5670 by 639, we get 8 and a remainder of 558.
The next digit of our result is 8. 
Result so far: 133838.478
The remainder is 558 after subtracting 5112 from 5670.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5580, and continue the process.

Advancing to step 12:
The number 639 fits into 5580 8 times, leaving a remainder of 468.
Write down 8 as next digit of the result. 
Result so far: 133838.4788
The remainder is 468 after subtracting 5112 from 5580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4680, and continue the process.

Our division results in 133838.4788 with a remaining 0.00468.
