18733580 ÷ 866 
We want to figure out the number of times 18733580 can be divided by 866.

Going ahead to step 1:
866 can be fit into 1 0 times, resulting in a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Fetch the next digit (8) from the dividend, attach it to 1 and continue: 18 / 866

Let's proceed to step 2:
When dividing 18 by 866, we get 0 with a remainder of 18.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 18 after subtracting 0 from 18.
Fetch the next digit (7) from the dividend, attach it to 18 and continue: 187 / 866

Moving on to step 3:
If we divide 187 by 866, we get 0 and a remainder of 187.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 187, we get 187.
Append the next digit (3) from the dividend to 187 and continue with: 1873 / 866

Going ahead to step 4:
866 can be fit into 1873 2 times, resulting in a remainder of 141.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we subtract 1732 from 1873, we get 141.
Take the next digit (3) from the dividend and append it to 141, then repeat: 1413 / 866

Going ahead to step 5:
866 goes into 1413 1 times with a remainder of 547.
Write down 1 as next digit of the result. 
Result so far: 21.0
Deduct 866 from 1413 and we're left with 547.
Bring next digit (5) of the dividend behind the 547 and repeat the process: 5475 / 866

Moving on to step 6:
5475 divided by 866 is 6 with a remainder of 279.
Use 6 as the next digit of our solution. 
Result so far: 216.0
Subtracting 5196 from 5475 leaves us with 279.
Fetch the next digit (8) from the dividend, attach it to 279 and continue: 2798 / 866

On to step 7:
2798 divided by 866 is 3 with a remainder of 200.
Put 3 as the next digit of the answer. 
Result so far: 2163.0
Subtract 2598 from 2798 to get 200.
Bring next digit (0) of the dividend behind the 200 and repeat the process: 2000 / 866

On to step 8:
866 can be fit into 2000 2 times, resulting in a remainder of 268.
The number 2 becomes the next digit in our result. 
Result so far: 21632.0
Deduct 1732 from 2000 and we're left with 268.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2680, and continue the process.

Let's proceed to step 9:
The number 866 fits into 2680 3 times, leaving a remainder of 82.
Use 3 as the next digit of our solution. 
Result so far: 21632.3
Subtract 2598 from 2680 to get 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Let's proceed to step 10:
The number 866 fits into 820 0 times, leaving a remainder of 820.
The number 0 becomes the next digit in our result. 
Result so far: 21632.3
If we take 0 away from 820, we end up with 820.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8200, and continue the process.

Moving on to step 11:
8200 divided by 866 is 9 with a remainder of 406.
Write down 9 as next digit of the result. 
Result so far: 21632.309
If we subtract 7794 from 8200, we get 406.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4060, and continue the process.

Moving on to step 12:
If we divide 4060 by 866, we get 4 and a remainder of 596.
The number 4 becomes the next digit in our result. 
Result so far: 21632.3094
Subtract 3464 from 4060 to get 596.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5960, and continue the process.

Step 13:
866 goes into 5960 6 times with a remainder of 764.
The next digit of our result is 6. 
Result so far: 21632.30946
If we subtract 5196 from 5960, we get 764.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7640, and continue the process.

Going ahead to step 14:
The number 866 fits into 7640 8 times, leaving a remainder of 712.
Use 8 as the next digit of our solution. 
Result so far: 21632.309468
The remainder is 712 after subtracting 6928 from 7640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7120, and continue the process.

On to step 15:
When dividing 7120 by 866, we get 8 with a remainder of 192.
Use 8 as the next digit of our solution. 
Result so far: 21632.3094688
Subtract 6928 from 7120 to get 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

The final outcome is 21632.3094688, with a leftover of 1.92e-06.
