Let's divide 72039 by 89
We want to divide 72039 by 89.

Advancing to step 1:
The number 89 fits into 7 0 times, leaving a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Include the next digit (2) from the dividend after 7, then repeat: 72 / 89

Step 2:
89 goes into 72 0 times with a remainder of 72.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 72, we end up with 72.
Bring next digit (0) of the dividend behind the 72 and repeat the process: 720 / 89

Going ahead to step 3:
The number 89 fits into 720 8 times, leaving a remainder of 8.
The next digit of our result is 8. 
Result so far: 8.0
The remainder is 8 after subtracting 712 from 720.
Append the next digit (3) from the dividend to 8 and continue with: 83 / 89

Step 4:
89 goes into 83 0 times with a remainder of 83.
Write down 0 as next digit of the result. 
Result so far: 80.0
Subtracting 0 from 83 leaves us with 83.
Fetch the next digit (9) from the dividend, attach it to 83 and continue: 839 / 89

Going ahead to step 5:
839 divided by 89 is 9 with a remainder of 38.
The next digit of our result is 9. 
Result so far: 809.0
Deduct 801 from 839 and we're left with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Going ahead to step 6:
If we divide 380 by 89, we get 4 and a remainder of 24.
The number 4 becomes the next digit in our result. 
Result so far: 809.4
Deduct 356 from 380 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 7:
The number 89 fits into 240 2 times, leaving a remainder of 62.
The next digit of our result is 2. 
Result so far: 809.42
If we subtract 178 from 240, we get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

On to step 8:
620 divided by 89 is 6 with a remainder of 86.
Put 6 as the next digit of the answer. 
Result so far: 809.426
The remainder is 86 after subtracting 534 from 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Let's proceed to step 9:
89 goes into 860 9 times with a remainder of 59.
Write down 9 as next digit of the result. 
Result so far: 809.4269
If we subtract 801 from 860, we get 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Step 10:
590 divided by 89 is 6 with a remainder of 56.
The number 6 becomes the next digit in our result. 
Result so far: 809.42696
The remainder is 56 after subtracting 534 from 590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Let's proceed to step 11:
If we divide 560 by 89, we get 6 and a remainder of 26.
Use 6 as the next digit of our solution. 
Result so far: 809.426966
If we take 534 away from 560, we end up with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

The quotient of the division is 809.426966, and the remainder is 2.6e-06.
