We're dividing 87028303 by 89 
Let's see how many times 89 fits into 87028303.

On to step 1:
The number 89 fits into 8 0 times, leaving a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Bring next digit (7) of the dividend behind the 8 and repeat the process: 87 / 89

Going ahead to step 2:
If we divide 87 by 89, we get 0 and a remainder of 87.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 87 leaves us with 87.
Append the next digit (0) from the dividend to 87 and continue with: 870 / 89

Going ahead to step 3:
89 can be fit into 870 9 times, resulting in a remainder of 69.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
Subtract 801 from 870 to get 69.
Bring next digit (2) of the dividend behind the 69 and repeat the process: 692 / 89

Going ahead to step 4:
When dividing 692 by 89, we get 7 with a remainder of 69.
The number 7 becomes the next digit in our result. 
Result so far: 97.0
The remainder is 69 after subtracting 623 from 692.
Grab the next digit (8) from the dividend, add it to 69, then carry on: 698 / 89

Let's proceed to step 5:
698 divided by 89 is 7 with a remainder of 75.
The number 7 becomes the next digit in our result. 
Result so far: 977.0
Subtract 623 from 698 to get 75.
Bring next digit (3) of the dividend behind the 75 and repeat the process: 753 / 89

Going ahead to step 6:
89 goes into 753 8 times with a remainder of 41.
Record the quotient 8 as the next digit in the result. 
Result so far: 9778.0
If we take 712 away from 753, we end up with 41.
Grab the next digit (0) from the dividend, add it to 41, then carry on: 410 / 89

On to step 7:
The number 89 fits into 410 4 times, leaving a remainder of 54.
The next digit of our result is 4. 
Result so far: 97784.0
If we take 356 away from 410, we end up with 54.
Take the next digit (3) from the dividend and append it to 54, then repeat: 543 / 89

Advancing to step 8:
543 divided by 89 is 6 with a remainder of 9.
Write down 6 as next digit of the result. 
Result so far: 977846.0
The remainder is 9 after subtracting 534 from 543.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 9:
When dividing 90 by 89, we get 1 with a remainder of 1.
Put 1 as the next digit of the answer. 
Result so far: 977846.1
If we subtract 89 from 90, we 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 10:
The number 89 fits into 10 0 times, leaving a remainder of 10.
The next digit of our result is 0. 
Result so far: 977846.1
If we subtract 0 from 10, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 11:
100 divided by 89 is 1 with a remainder of 11.
Put 1 as the next digit of the answer. 
Result so far: 977846.101
If we subtract 89 from 100, we 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.

Moving on to step 12:
89 goes into 110 1 times with a remainder of 21.
Use 1 as the next digit of our solution. 
Result so far: 977846.1011
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.

The final result is 977846.1011 with a remainder of 0.00021.
