We look at the division of 89163970 by 288 
Our goal is to divide 89163970 by 288.

Let's proceed to step 1:
When dividing 8 by 288, we get 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Append the next digit (9) from the dividend to 8 and continue with: 89 / 288

On to step 2:
288 can be fit into 89 0 times, resulting in a remainder of 89.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 89 after subtracting 0 from 89.
Take the next digit (1) from the dividend and append it to 89, then repeat: 891 / 288

Going ahead to step 3:
The number 288 fits into 891 3 times, leaving a remainder of 27.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Deduct 864 from 891 and we're left with 27.
Bring next digit (6) of the dividend behind the 27 and repeat the process: 276 / 288

Moving on to step 4:
The number 288 fits into 276 0 times, leaving a remainder of 276.
Use 0 as the next digit of our solution. 
Result so far: 30.0
If we take 0 away from 276, we end up with 276.
Take the next digit (3) from the dividend and append it to 276, then repeat: 2763 / 288

Let's proceed to step 5:
The number 288 fits into 2763 9 times, leaving a remainder of 171.
Put 9 as the next digit of the answer. 
Result so far: 309.0
Subtract 2592 from 2763 to get 171.
Bring next digit (9) of the dividend behind the 171 and repeat the process: 1719 / 288

Step 6:
When dividing 1719 by 288, we get 5 with a remainder of 279.
Record the quotient 5 as the next digit in the result. 
Result so far: 3095.0
If we subtract 1440 from 1719, we get 279.
Take the next digit (7) from the dividend and append it to 279, then repeat: 2797 / 288

On to step 7:
The number 288 fits into 2797 9 times, leaving a remainder of 205.
Put 9 as the next digit of the answer. 
Result so far: 30959.0
If we subtract 2592 from 2797, we get 205.
Grab the next digit (0) from the dividend, add it to 205, then carry on: 2050 / 288

Advancing to step 8:
288 goes into 2050 7 times with a remainder of 34.
Put 7 as the next digit of the answer. 
Result so far: 309597.0
Deduct 2016 from 2050 and we're left with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

On to step 9:
288 can be fit into 340 1 times, resulting in a remainder of 52.
Write down 1 as next digit of the result. 
Result so far: 309597.1
Subtracting 288 from 340 leaves us with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Advancing to step 10:
If we divide 520 by 288, we get 1 and a remainder of 232.
The next digit of our result is 1. 
Result so far: 309597.11
Subtract 288 from 520 to get 232.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2320, and continue the process.

The final outcome is 309597.11, with a leftover of 0.232.
