We look at the division of 80789049 by 866 
Our goal is to divide 80789049 by 866.

Advancing to step 1:
If we divide 8 by 866, we get 0 and a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Fetch the next digit (0) from the dividend, attach it to 8 and continue: 80 / 866

Step 2:
If we divide 80 by 866, we get 0 and a remainder of 80.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 80 and we're left with 80.
Grab the next digit (7) from the dividend, add it to 80, then carry on: 807 / 866

Let's proceed to step 3:
866 goes into 807 0 times with a remainder of 807.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 807 and we're left with 807.
Grab the next digit (8) from the dividend, add it to 807, then carry on: 8078 / 866

On to step 4:
If we divide 8078 by 866, we get 9 and a remainder of 284.
The next digit of our result is 9. 
Result so far: 9.0
Subtracting 7794 from 8078 leaves us with 284.
Fetch the next digit (9) from the dividend, attach it to 284 and continue: 2849 / 866

Moving on to step 5:
If we divide 2849 by 866, we get 3 and a remainder of 251.
Use 3 as the next digit of our solution. 
Result so far: 93.0
Subtracting 2598 from 2849 leaves us with 251.
Take the next digit (0) from the dividend and append it to 251, then repeat: 2510 / 866

Moving on to step 6:
When dividing 2510 by 866, we get 2 with a remainder of 778.
Record the quotient 2 as the next digit in the result. 
Result so far: 932.0
Deduct 1732 from 2510 and we're left with 778.
Grab the next digit (4) from the dividend, add it to 778, then carry on: 7784 / 866

Moving on to step 7:
866 goes into 7784 8 times with a remainder of 856.
The number 8 becomes the next digit in our result. 
Result so far: 9328.0
If we take 6928 away from 7784, we end up with 856.
Include the next digit (9) from the dividend after 856, then repeat: 8569 / 866

Going ahead to step 8:
If we divide 8569 by 866, we get 9 and a remainder of 775.
Use 9 as the next digit of our solution. 
Result so far: 93289.0
Subtract 7794 from 8569 to get 775.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7750, and continue the process.

Let's proceed to step 9:
If we divide 7750 by 866, we get 8 and a remainder of 822.
The next digit of our result is 8. 
Result so far: 93289.8
Deduct 6928 from 7750 and we're left with 822.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8220, and continue the process.

Going ahead to step 10:
866 goes into 8220 9 times with a remainder of 426.
Put 9 as the next digit of the answer. 
Result so far: 93289.89
If we take 7794 away from 8220, we end up with 426.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4260, and continue the process.

Let's proceed to step 11:
866 can be fit into 4260 4 times, resulting in a remainder of 796.
Put 4 as the next digit of the answer. 
Result so far: 93289.894
If we take 3464 away from 4260, we end up with 796.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7960, and continue the process.

Step 12:
When dividing 7960 by 866, we get 9 with a remainder of 166.
Write down 9 as next digit of the result. 
Result so far: 93289.8949
If we take 7794 away from 7960, we end up with 166.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1660, and continue the process.

Let's proceed to step 13:
866 goes into 1660 1 times with a remainder of 794.
Put 1 as the next digit of the answer. 
Result so far: 93289.89491
Subtract 866 from 1660 to get 794.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7940, and continue the process.

Let's proceed to step 14:
866 can be fit into 7940 9 times, resulting in a remainder of 146.
The next digit of our result is 9. 
Result so far: 93289.894919
Subtract 7794 from 7940 to get 146.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1460, and continue the process.

Moving on to step 15:
1460 divided by 866 is 1 with a remainder of 594.
Put 1 as the next digit of the answer. 
Result so far: 93289.8949191
The remainder is 594 after subtracting 866 from 1460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5940, and continue the process.

Moving on to step 16:
If we divide 5940 by 866, we get 6 and a remainder of 744.
Write down 6 as next digit of the result. 
Result so far: 93289.89491916
Deduct 5196 from 5940 and we're left with 744.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7440, and continue the process.

The quotient of the division is 93289.89491916, and the remainder is 7.44e-07.
