96781018 divided by 639 
We're looking to find how many times 639 goes into 96781018.

Let's proceed to step 1:
When dividing 9 by 639, we get 0 with a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Include the next digit (6) from the dividend after 9, then repeat: 96 / 639

On to step 2:
96 divided by 639 is 0 with a remainder of 96.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 96, we end up with 96.
Take the next digit (7) from the dividend and append it to 96, then repeat: 967 / 639

Moving on to step 3:
When dividing 967 by 639, we get 1 with a remainder of 328.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 639 away from 967, we end up with 328.
Append the next digit (8) from the dividend to 328 and continue with: 3288 / 639

Step 4:
639 can be fit into 3288 5 times, resulting in a remainder of 93.
Record the quotient 5 as the next digit in the result. 
Result so far: 15.0
If we take 3195 away from 3288, we end up with 93.
Append the next digit (1) from the dividend to 93 and continue with: 931 / 639

Let's proceed to step 5:
931 divided by 639 is 1 with a remainder of 292.
The next digit of our result is 1. 
Result so far: 151.0
Subtract 639 from 931 to get 292.
Append the next digit (0) from the dividend to 292 and continue with: 2920 / 639

Going ahead to step 6:
When dividing 2920 by 639, we get 4 with a remainder of 364.
Record the quotient 4 as the next digit in the result. 
Result so far: 1514.0
Deduct 2556 from 2920 and we're left with 364.
Grab the next digit (1) from the dividend, add it to 364, then carry on: 3641 / 639

Advancing to step 7:
639 goes into 3641 5 times with a remainder of 446.
Record the quotient 5 as the next digit in the result. 
Result so far: 15145.0
If we take 3195 away from 3641, we end up with 446.
Append the next digit (8) from the dividend to 446 and continue with: 4468 / 639

Let's proceed to step 8:
4468 divided by 639 is 6 with a remainder of 634.
The next digit of our result is 6. 
Result so far: 151456.0
Subtract 3834 from 4468 to get 634.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6340, and continue the process.

Advancing to step 9:
639 can be fit into 6340 9 times, resulting in a remainder of 589.
Write down 9 as next digit of the result. 
Result so far: 151456.9
Subtracting 5751 from 6340 leaves us with 589.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5890, and continue the process.

Advancing to step 10:
If we divide 5890 by 639, we get 9 and a remainder of 139.
Put 9 as the next digit of the answer. 
Result so far: 151456.99
Subtracting 5751 from 5890 leaves us with 139.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1390, and continue the process.

Our division results in 151456.99 with a remaining 0.139.
