We divide 72689686 by 639
We want to figure out the number of times 72689686 can be divided by 639.

Advancing to step 1:
639 can be fit into 7 0 times, resulting in a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Append the next digit (2) from the dividend to 7 and continue with: 72 / 639

Going ahead to step 2:
639 goes into 72 0 times with a remainder of 72.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 72 after subtracting 0 from 72.
Append the next digit (6) from the dividend to 72 and continue with: 726 / 639

Going ahead to step 3:
726 divided by 639 is 1 with a remainder of 87.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 87 after subtracting 639 from 726.
Fetch the next digit (8) from the dividend, attach it to 87 and continue: 878 / 639

Step 4:
639 goes into 878 1 times with a remainder of 239.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
If we subtract 639 from 878, we get 239.
Include the next digit (9) from the dividend after 239, then repeat: 2399 / 639

Let's proceed to step 5:
2399 divided by 639 is 3 with a remainder of 482.
Use 3 as the next digit of our solution. 
Result so far: 113.0
If we take 1917 away from 2399, we end up with 482.
Fetch the next digit (6) from the dividend, attach it to 482 and continue: 4826 / 639

Moving on to step 6:
If we divide 4826 by 639, we get 7 and a remainder of 353.
Write down 7 as next digit of the result. 
Result so far: 1137.0
If we subtract 4473 from 4826, we get 353.
Bring next digit (8) of the dividend behind the 353 and repeat the process: 3538 / 639

Moving on to step 7:
The number 639 fits into 3538 5 times, leaving a remainder of 343.
Record the quotient 5 as the next digit in the result. 
Result so far: 11375.0
Subtract 3195 from 3538 to get 343.
Bring next digit (6) of the dividend behind the 343 and repeat the process: 3436 / 639

Step 8:
639 can be fit into 3436 5 times, resulting in a remainder of 241.
Record the quotient 5 as the next digit in the result. 
Result so far: 113755.0
Subtract 3195 from 3436 to get 241.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2410, and continue the process.

Going ahead to step 9:
The number 639 fits into 2410 3 times, leaving a remainder of 493.
Put 3 as the next digit of the answer. 
Result so far: 113755.3
If we subtract 1917 from 2410, we get 493.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4930, and continue the process.

Advancing to step 10:
The number 639 fits into 4930 7 times, leaving a remainder of 457.
Put 7 as the next digit of the answer. 
Result so far: 113755.37
Deduct 4473 from 4930 and we're left with 457.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4570, and continue the process.

Let's proceed to step 11:
When dividing 4570 by 639, we get 7 with a remainder of 97.
Use 7 as the next digit of our solution. 
Result so far: 113755.377
Subtracting 4473 from 4570 leaves us with 97.
Since there are no more digits in the dividend, we add a zero to the remainder making it 970, and continue the process.

The final result is 113755.377 with a remainder of 0.0097.
