10323510 divided by 866 
We want to figure out the number of times 10323510 can be divided by 866.

Moving on to step 1:
1 divided by 866 is 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Include the next digit (0) from the dividend after 1, then repeat: 10 / 866

Step 2:
The number 866 fits into 10 0 times, leaving a remainder of 10.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 10 after subtracting 0 from 10.
Bring next digit (3) of the dividend behind the 10 and repeat the process: 103 / 866

Let's proceed to step 3:
If we divide 103 by 866, we get 0 and a remainder of 103.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 103 after subtracting 0 from 103.
Append the next digit (2) from the dividend to 103 and continue with: 1032 / 866

Advancing to step 4:
866 goes into 1032 1 times with a remainder of 166.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 866 from 1032 and we're left with 166.
Include the next digit (3) from the dividend after 166, then repeat: 1663 / 866

Let's proceed to step 5:
When dividing 1663 by 866, we get 1 with a remainder of 797.
Use 1 as the next digit of our solution. 
Result so far: 11.0
Deduct 866 from 1663 and we're left with 797.
Append the next digit (5) from the dividend to 797 and continue with: 7975 / 866

Step 6:
If we divide 7975 by 866, we get 9 and a remainder of 181.
Use 9 as the next digit of our solution. 
Result so far: 119.0
If we subtract 7794 from 7975, we get 181.
Append the next digit (1) from the dividend to 181 and continue with: 1811 / 866

Moving on to step 7:
866 goes into 1811 2 times with a remainder of 79.
The next digit of our result is 2. 
Result so far: 1192.0
Subtracting 1732 from 1811 leaves us with 79.
Append the next digit (0) from the dividend to 79 and continue with: 790 / 866

Going ahead to step 8:
When dividing 790 by 866, we get 0 with a remainder of 790.
Put 0 as the next digit of the answer. 
Result so far: 11920.0
The remainder is 790 after subtracting 0 from 790.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7900, and continue the process.

Going ahead to step 9:
The number 866 fits into 7900 9 times, leaving a remainder of 106.
Use 9 as the next digit of our solution. 
Result so far: 11920.9
If we subtract 7794 from 7900, we get 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

Moving on to step 10:
When dividing 1060 by 866, we get 1 with a remainder of 194.
Put 1 as the next digit of the answer. 
Result so far: 11920.91
If we take 866 away from 1060, we end up with 194.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1940, and continue the process.

Going ahead to step 11:
866 goes into 1940 2 times with a remainder of 208.
Record the quotient 2 as the next digit in the result. 
Result so far: 11920.912
Subtract 1732 from 1940 to get 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

On to step 12:
When dividing 2080 by 866, we get 2 with a remainder of 348.
The number 2 becomes the next digit in our result. 
Result so far: 11920.9122
If we subtract 1732 from 2080, we get 348.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3480, and continue the process.

The final outcome is 11920.9122, with a leftover of 0.00348.
