We're dividing 17128450 by 866 
Let's see how many times 866 fits into 17128450.

Going ahead to step 1:
If we divide 1 by 866, we get 0 and a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Fetch the next digit (7) from the dividend, attach it to 1 and continue: 17 / 866

On to step 2:
If we divide 17 by 866, we get 0 and a remainder of 17.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 17 leaves us with 17.
Bring next digit (1) of the dividend behind the 17 and repeat the process: 171 / 866

Let's proceed to step 3:
171 divided by 866 is 0 with a remainder of 171.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 171 after subtracting 0 from 171.
Append the next digit (2) from the dividend to 171 and continue with: 1712 / 866

Let's proceed to step 4:
866 can be fit into 1712 1 times, resulting in a remainder of 846.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 866 from 1712 to get 846.
Bring next digit (8) of the dividend behind the 846 and repeat the process: 8468 / 866

Let's proceed to step 5:
If we divide 8468 by 866, we get 9 and a remainder of 674.
Record the quotient 9 as the next digit in the result. 
Result so far: 19.0
The remainder is 674 after subtracting 7794 from 8468.
Append the next digit (4) from the dividend to 674 and continue with: 6744 / 866

On to step 6:
If we divide 6744 by 866, we get 7 and a remainder of 682.
The number 7 becomes the next digit in our result. 
Result so far: 197.0
The remainder is 682 after subtracting 6062 from 6744.
Append the next digit (5) from the dividend to 682 and continue with: 6825 / 866

Step 7:
866 goes into 6825 7 times with a remainder of 763.
Put 7 as the next digit of the answer. 
Result so far: 1977.0
Deduct 6062 from 6825 and we're left with 763.
Bring next digit (0) of the dividend behind the 763 and repeat the process: 7630 / 866

On to step 8:
7630 divided by 866 is 8 with a remainder of 702.
Record the quotient 8 as the next digit in the result. 
Result so far: 19778.0
The remainder is 702 after subtracting 6928 from 7630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7020, and continue the process.

Moving on to step 9:
When dividing 7020 by 866, we get 8 with a remainder of 92.
Record the quotient 8 as the next digit in the result. 
Result so far: 19778.8
Subtracting 6928 from 7020 leaves us with 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Step 10:
The number 866 fits into 920 1 times, leaving a remainder of 54.
The number 1 becomes the next digit in our result. 
Result so far: 19778.81
If we take 866 away from 920, 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:
866 can be fit into 540 0 times, resulting in a remainder of 540.
Put 0 as the next digit of the answer. 
Result so far: 19778.81
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.

Let's proceed to step 12:
If we divide 5400 by 866, we get 6 and a remainder of 204.
Record the quotient 6 as the next digit in the result. 
Result so far: 19778.8106
The remainder is 204 after subtracting 5196 from 5400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2040, and continue the process.

Let's proceed to step 13:
When dividing 2040 by 866, we get 2 with a remainder of 308.
Record the quotient 2 as the next digit in the result. 
Result so far: 19778.81062
If we subtract 1732 from 2040, we get 308.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3080, and continue the process.

Let's proceed to step 14:
866 goes into 3080 3 times with a remainder of 482.
Use 3 as the next digit of our solution. 
Result so far: 19778.810623
Subtracting 2598 from 3080 leaves us with 482.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4820, and continue the process.

Step 15:
866 can be fit into 4820 5 times, resulting in a remainder of 490.
The next digit of our result is 5. 
Result so far: 19778.8106235
Subtracting 4330 from 4820 leaves us with 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4900, and continue the process.

Step 16:
866 goes into 4900 5 times with a remainder of 570.
The number 5 becomes the next digit in our result. 
Result so far: 19778.81062355
Deduct 4330 from 4900 and we're left 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.

The quotient of the division is 19778.81062355, and the remainder is 5.7e-07.
