We look at the division of 89437150 by 660 
We want to divide 89437150 by 660.

Moving on to step 1:
If we divide 8 by 660, we get 0 and a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Include the next digit (9) from the dividend after 8, then repeat: 89 / 660

Advancing to step 2:
89 divided by 660 is 0 with a remainder of 89.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 89 after subtracting 0 from 89.
Fetch the next digit (4) from the dividend, attach it to 89 and continue: 894 / 660

Moving on to step 3:
If we divide 894 by 660, we get 1 and a remainder of 234.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 660 away from 894, we end up with 234.
Grab the next digit (3) from the dividend, add it to 234, then carry on: 2343 / 660

Moving on to step 4:
2343 divided by 660 is 3 with a remainder of 363.
The next digit of our result is 3. 
Result so far: 13.0
Deduct 1980 from 2343 and we're left with 363.
Fetch the next digit (7) from the dividend, attach it to 363 and continue: 3637 / 660

On to step 5:
If we divide 3637 by 660, we get 5 and a remainder of 337.
Use 5 as the next digit of our solution. 
Result so far: 135.0
If we take 3300 away from 3637, we end up with 337.
Take the next digit (1) from the dividend and append it to 337, then repeat: 3371 / 660

Moving on to step 6:
If we divide 3371 by 660, we get 5 and a remainder of 71.
Put 5 as the next digit of the answer. 
Result so far: 1355.0
The remainder is 71 after subtracting 3300 from 3371.
Fetch the next digit (5) from the dividend, attach it to 71 and continue: 715 / 660

Going ahead to step 7:
715 divided by 660 is 1 with a remainder of 55.
Record the quotient 1 as the next digit in the result. 
Result so far: 13551.0
If we subtract 660 from 715, we get 55.
Grab the next digit (0) from the dividend, add it to 55, then carry on: 550 / 660

Advancing to step 8:
660 goes into 550 0 times with a remainder of 550.
Put 0 as the next digit of the answer. 
Result so far: 135510.0
Subtract 0 from 550 to get 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5500, and continue the process.

Going ahead to step 9:
660 can be fit into 5500 8 times, resulting in a remainder of 220.
The number 8 becomes the next digit in our result. 
Result so far: 135510.8
If we subtract 5280 from 5500, we get 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Step 10:
660 can be fit into 2200 3 times, resulting in a remainder of 220.
Record the quotient 3 as the next digit in the result. 
Result so far: 135510.83
Subtracting 1980 from 2200 leaves us with 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Let's proceed to step 11:
2200 divided by 660 is 3 with a remainder of 220.
The next digit of our result is 3. 
Result so far: 135510.833
Deduct 1980 from 2200 and we're left with 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

In conclusion, the division gives 135510.833 with a balance of 0.022.
