We look at the division of 87558540 by 966 
We want to divide 87558540 by 966.

Let's proceed to step 1:
When dividing 8 by 966, we get 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Include the next digit (7) from the dividend after 8, then repeat: 87 / 966

Let's proceed to step 2:
966 can be fit into 87 0 times, resulting in a remainder of 87.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 87, we end up with 87.
Fetch the next digit (5) from the dividend, attach it to 87 and continue: 875 / 966

Going ahead to step 3:
If we divide 875 by 966, we get 0 and a remainder of 875.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 875, we end up with 875.
Take the next digit (5) from the dividend and append it to 875, then repeat: 8755 / 966

Moving on to step 4:
The number 966 fits into 8755 9 times, leaving a remainder of 61.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
If we subtract 8694 from 8755, we get 61.
Take the next digit (8) from the dividend and append it to 61, then repeat: 618 / 966

Going ahead to step 5:
966 can be fit into 618 0 times, resulting in a remainder of 618.
The number 0 becomes the next digit in our result. 
Result so far: 90.0
Subtracting 0 from 618 leaves us with 618.
Append the next digit (5) from the dividend to 618 and continue with: 6185 / 966

Advancing to step 6:
966 can be fit into 6185 6 times, resulting in a remainder of 389.
Record the quotient 6 as the next digit in the result. 
Result so far: 906.0
Subtracting 5796 from 6185 leaves us with 389.
Fetch the next digit (4) from the dividend, attach it to 389 and continue: 3894 / 966

Advancing to step 7:
If we divide 3894 by 966, we get 4 and a remainder of 30.
Put 4 as the next digit of the answer. 
Result so far: 9064.0
Subtract 3864 from 3894 to get 30.
Fetch the next digit (0) from the dividend, attach it to 30 and continue: 300 / 966

Advancing to step 8:
If we divide 300 by 966, we get 0 and a remainder of 300.
The number 0 becomes the next digit in our result. 
Result so far: 90640.0
If we take 0 away from 300, we end up with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Advancing to step 9:
3000 divided by 966 is 3 with a remainder of 102.
The next digit of our result is 3. 
Result so far: 90640.3
If we take 2898 away from 3000, we end up with 102.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

Step 10:
The number 966 fits into 1020 1 times, leaving a remainder of 54.
The next digit of our result is 1. 
Result so far: 90640.31
If we take 966 away from 1020, we end up with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Let's proceed to step 11:
966 goes into 540 0 times with a remainder of 540.
The next digit of our result is 0. 
Result so far: 90640.31
If we subtract 0 from 540, we get 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5400, and continue the process.

On to step 12:
5400 divided by 966 is 5 with a remainder of 570.
Record the quotient 5 as the next digit in the result. 
Result so far: 90640.3105
If we take 4830 away from 5400, we end up with 570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5700, and continue the process.

Moving on to step 13:
If we divide 5700 by 966, we get 5 and a remainder of 870.
Put 5 as the next digit of the answer. 
Result so far: 90640.31055
Subtract 4830 from 5700 to get 870.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8700, and continue the process.

The final outcome is 90640.31055, with a leftover of 0.00087.
