We're dividing 728991 by 89 
Our goal is to divide 728991 by 89.

Step 1:
7 divided by 89 is 0 with 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 / 89

On to step 2:
89 can be fit into 72 0 times, resulting in a remainder of 72.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 72 and we're left with 72.
Include the next digit (8) from the dividend after 72, then repeat: 728 / 89

Advancing to step 3:
89 goes into 728 8 times with a remainder of 16.
Write down 8 as next digit of the result. 
Result so far: 8.0
If we take 712 away from 728, we end up with 16.
Fetch the next digit (9) from the dividend, attach it to 16 and continue: 169 / 89

Going ahead to step 4:
89 goes into 169 1 times with a remainder of 80.
Record the quotient 1 as the next digit in the result. 
Result so far: 81.0
If we subtract 89 from 169, we get 80.
Bring next digit (9) of the dividend behind the 80 and repeat the process: 809 / 89

On to step 5:
89 can be fit into 809 9 times, resulting in a remainder of 8.
Write down 9 as next digit of the result. 
Result so far: 819.0
If we subtract 801 from 809, we get 8.
Grab the next digit (1) from the dividend, add it to 8, then carry on: 81 / 89

Moving on to step 6:
The number 89 fits into 81 0 times, leaving a remainder of 81.
The number 0 becomes the next digit in our result. 
Result so far: 8190.0
Deduct 0 from 81 and we're left with 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Step 7:
When dividing 810 by 89, we get 9 with a remainder of 9.
The next digit of our result is 9. 
Result so far: 8190.9
Subtract 801 from 810 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Advancing to step 8:
If we divide 90 by 89, we get 1 and a remainder of 1.
Record the quotient 1 as the next digit in the result. 
Result so far: 8190.91
Subtract 89 from 90 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 9:
If we divide 10 by 89, we get 0 and a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 8190.91
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 10:
89 can be fit into 100 1 times, resulting in a remainder of 11.
Record the quotient 1 as the next digit in the result. 
Result so far: 8190.9101
Subtract 89 from 100 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Let's proceed to step 11:
If we divide 110 by 89, we get 1 and a remainder of 21.
The next digit of our result is 1. 
Result so far: 8190.91011
Deduct 89 from 110 and we're left with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

After the division, we end up with 8190.91011 and a remainder of 2.1e-05.
