26512748 divided by 639 
We're looking to find how many times 639 goes into 26512748.

Step 1:
When dividing 2 by 639, we get 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Take the next digit (6) from the dividend and append it to 2, then repeat: 26 / 639

Advancing to step 2:
639 can be fit into 26 0 times, resulting in a remainder of 26.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 26, we get 26.
Append the next digit (5) from the dividend to 26 and continue with: 265 / 639

Going ahead to step 3:
When dividing 265 by 639, we get 0 with a remainder of 265.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 265, we end up with 265.
Grab the next digit (1) from the dividend, add it to 265, then carry on: 2651 / 639

Advancing to step 4:
639 can be fit into 2651 4 times, resulting in a remainder of 95.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
The remainder is 95 after subtracting 2556 from 2651.
Fetch the next digit (2) from the dividend, attach it to 95 and continue: 952 / 639

Moving on to step 5:
If we divide 952 by 639, we get 1 and a remainder of 313.
Record the quotient 1 as the next digit in the result. 
Result so far: 41.0
Deduct 639 from 952 and we're left with 313.
Append the next digit (7) from the dividend to 313 and continue with: 3137 / 639

Going ahead to step 6:
3137 divided by 639 is 4 with a remainder of 581.
The next digit of our result is 4. 
Result so far: 414.0
Subtracting 2556 from 3137 leaves us with 581.
Take the next digit (4) from the dividend and append it to 581, then repeat: 5814 / 639

Going ahead to step 7:
The number 639 fits into 5814 9 times, leaving a remainder of 63.
The number 9 becomes the next digit in our result. 
Result so far: 4149.0
If we subtract 5751 from 5814, we get 63.
Fetch the next digit (8) from the dividend, attach it to 63 and continue: 638 / 639

Going ahead to step 8:
The number 639 fits into 638 0 times, leaving a remainder of 638.
The number 0 becomes the next digit in our result. 
Result so far: 41490.0
Subtract 0 from 638 to get 638.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6380, and continue the process.

Moving on to step 9:
If we divide 6380 by 639, we get 9 and a remainder of 629.
Write down 9 as next digit of the result. 
Result so far: 41490.9
Deduct 5751 from 6380 and we're left with 629.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6290, and continue the process.

Going ahead to step 10:
6290 divided by 639 is 9 with a remainder of 539.
Write down 9 as next digit of the result. 
Result so far: 41490.99
Deduct 5751 from 6290 and we're left with 539.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5390, and continue the process.

The final outcome is 41490.99, with a leftover of 0.539.
