We look at the division of 72710294 by 639 
Let's see how many times 639 fits into 72710294.

Step 1:
7 divided by 639 is 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Include the next digit (2) from the dividend after 7, then repeat: 72 / 639

Advancing to step 2:
The number 639 fits into 72 0 times, leaving a remainder of 72.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 72 after subtracting 0 from 72.
Append the next digit (7) from the dividend to 72 and continue with: 727 / 639

Advancing to step 3:
When dividing 727 by 639, we get 1 with a remainder of 88.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 639 from 727 to get 88.
Fetch the next digit (1) from the dividend, attach it to 88 and continue: 881 / 639

Moving on to step 4:
639 goes into 881 1 times with a remainder of 242.
Write down 1 as next digit of the result. 
Result so far: 11.0
Subtracting 639 from 881 leaves us with 242.
Append the next digit (0) from the dividend to 242 and continue with: 2420 / 639

Step 5:
2420 divided by 639 is 3 with a remainder of 503.
The number 3 becomes the next digit in our result. 
Result so far: 113.0
Subtract 1917 from 2420 to get 503.
Fetch the next digit (2) from the dividend, attach it to 503 and continue: 5032 / 639

Step 6:
When dividing 5032 by 639, we get 7 with a remainder of 559.
Record the quotient 7 as the next digit in the result. 
Result so far: 1137.0
If we subtract 4473 from 5032, we get 559.
Take the next digit (9) from the dividend and append it to 559, then repeat: 5599 / 639

On to step 7:
If we divide 5599 by 639, we get 8 and a remainder of 487.
The number 8 becomes the next digit in our result. 
Result so far: 11378.0
The remainder is 487 after subtracting 5112 from 5599.
Append the next digit (4) from the dividend to 487 and continue with: 4874 / 639

On to step 8:
639 can be fit into 4874 7 times, resulting in a remainder of 401.
Use 7 as the next digit of our solution. 
Result so far: 113787.0
Subtract 4473 from 4874 to get 401.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4010, and continue the process.

Step 9:
4010 divided by 639 is 6 with a remainder of 176.
The next digit of our result is 6. 
Result so far: 113787.6
If we take 3834 away from 4010, we end up with 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

On to step 10:
1760 divided by 639 is 2 with a remainder of 482.
Record the quotient 2 as the next digit in the result. 
Result so far: 113787.62
The remainder is 482 after subtracting 1278 from 1760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4820, and continue the process.

Step 11:
639 goes into 4820 7 times with a remainder of 347.
The next digit of our result is 7. 
Result so far: 113787.627
Subtracting 4473 from 4820 leaves us with 347.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3470, and continue the process.

Let's proceed to step 12:
3470 divided by 639 is 5 with a remainder of 275.
Put 5 as the next digit of the answer. 
Result so far: 113787.6275
Subtracting 3195 from 3470 leaves us with 275.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2750, and continue the process.

On to step 13:
When dividing 2750 by 639, we get 4 with a remainder of 194.
Write down 4 as next digit of the result. 
Result so far: 113787.62754
The remainder is 194 after subtracting 2556 from 2750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1940, and continue the process.

On to step 14:
639 goes into 1940 3 times with a remainder of 23.
The next digit of our result is 3. 
Result so far: 113787.627543
Subtract 1917 from 1940 to get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Advancing to step 15:
639 goes into 230 0 times with a remainder of 230.
The next digit of our result is 0. 
Result so far: 113787.627543
Deduct 0 from 230 and we're left with 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Going ahead to step 16:
When dividing 2300 by 639, we get 3 with a remainder of 383.
Record the quotient 3 as the next digit in the result. 
Result so far: 113787.62754303
If we subtract 1917 from 2300, we get 383.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3830, and continue the process.

Our division results in 113787.62754303 with a remaining 3.83e-07.
