We look at the division of 19794470 by 866 
We want to divide 19794470 by 866.

On to step 1:
If we divide 1 by 866, we get 0 and a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Include the next digit (9) from the dividend after 1, then repeat: 19 / 866

Step 2:
866 goes into 19 0 times with a remainder of 19.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 19 to get 19.
Take the next digit (7) from the dividend and append it to 19, then repeat: 197 / 866

On to step 3:
197 divided by 866 is 0 with a remainder of 197.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 197, we get 197.
Bring next digit (9) of the dividend behind the 197 and repeat the process: 1979 / 866

Going ahead to step 4:
866 goes into 1979 2 times with a remainder of 247.
Write down 2 as next digit of the result. 
Result so far: 2.0
Deduct 1732 from 1979 and we're left with 247.
Grab the next digit (4) from the dividend, add it to 247, then carry on: 2474 / 866

Step 5:
When dividing 2474 by 866, we get 2 with a remainder of 742.
Write down 2 as next digit of the result. 
Result so far: 22.0
Subtracting 1732 from 2474 leaves us with 742.
Take the next digit (4) from the dividend and append it to 742, then repeat: 7424 / 866

Step 6:
7424 divided by 866 is 8 with a remainder of 496.
Write down 8 as next digit of the result. 
Result so far: 228.0
If we take 6928 away from 7424, we end up with 496.
Take the next digit (7) from the dividend and append it to 496, then repeat: 4967 / 866

Let's proceed to step 7:
When dividing 4967 by 866, we get 5 with a remainder of 637.
The number 5 becomes the next digit in our result. 
Result so far: 2285.0
Deduct 4330 from 4967 and we're left with 637.
Include the next digit (0) from the dividend after 637, then repeat: 6370 / 866

Step 8:
If we divide 6370 by 866, we get 7 and a remainder of 308.
Write down 7 as next digit of the result. 
Result so far: 22857.0
Subtract 6062 from 6370 to 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.

On to step 9:
866 goes into 3080 3 times with a remainder of 482.
Record the quotient 3 as the next digit in the result. 
Result so far: 22857.3
Subtract 2598 from 3080 to get 482.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4820, and continue the process.

Going ahead to step 10:
4820 divided by 866 is 5 with a remainder of 490.
The next digit of our result is 5. 
Result so far: 22857.35
If we take 4330 away from 4820, we end up 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.

Going ahead to step 11:
The number 866 fits into 4900 5 times, leaving a remainder of 570.
Write down 5 as next digit of the result. 
Result so far: 22857.355
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 final outcome is 22857.355, with a leftover of 0.057.
