We're dividing 86667973 by 809 
We're looking to find how many times 809 goes into 86667973.

On to step 1:
If we divide 8 by 809, we get 0 and a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Grab the next digit (6) from the dividend, add it to 8, then carry on: 86 / 809

Going ahead to step 2:
86 divided by 809 is 0 with a remainder of 86.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 86 after subtracting 0 from 86.
Include the next digit (6) from the dividend after 86, then repeat: 866 / 809

Advancing to step 3:
The number 809 fits into 866 1 times, leaving a remainder of 57.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 809 from 866, we get 57.
Append the next digit (6) from the dividend to 57 and continue with: 576 / 809

On to step 4:
If we divide 576 by 809, we get 0 and a remainder of 576.
Write down 0 as next digit of the result. 
Result so far: 10.0
The remainder is 576 after subtracting 0 from 576.
Fetch the next digit (7) from the dividend, attach it to 576 and continue: 5767 / 809

Step 5:
When dividing 5767 by 809, we get 7 with a remainder of 104.
Use 7 as the next digit of our solution. 
Result so far: 107.0
The remainder is 104 after subtracting 5663 from 5767.
Grab the next digit (9) from the dividend, add it to 104, then carry on: 1049 / 809

On to step 6:
809 goes into 1049 1 times with a remainder of 240.
The number 1 becomes the next digit in our result. 
Result so far: 1071.0
If we take 809 away from 1049, we end up with 240.
Include the next digit (7) from the dividend after 240, then repeat: 2407 / 809

Step 7:
809 can be fit into 2407 2 times, resulting in a remainder of 789.
Write down 2 as next digit of the result. 
Result so far: 10712.0
If we subtract 1618 from 2407, we get 789.
Include the next digit (3) from the dividend after 789, then repeat: 7893 / 809

On to step 8:
809 goes into 7893 9 times with a remainder of 612.
The number 9 becomes the next digit in our result. 
Result so far: 107129.0
Subtract 7281 from 7893 to get 612.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6120, and continue the process.

On to step 9:
809 goes into 6120 7 times with a remainder of 457.
Write down 7 as next digit of the result. 
Result so far: 107129.7
Subtract 5663 from 6120 to get 457.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4570, and continue the process.

Moving on to step 10:
809 can be fit into 4570 5 times, resulting in a remainder of 525.
Record the quotient 5 as the next digit in the result. 
Result so far: 107129.75
The remainder is 525 after subtracting 4045 from 4570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5250, and continue the process.

Advancing to step 11:
When dividing 5250 by 809, we get 6 with a remainder of 396.
Put 6 as the next digit of the answer. 
Result so far: 107129.756
Subtract 4854 from 5250 to get 396.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3960, and continue the process.

Going ahead to step 12:
809 can be fit into 3960 4 times, resulting in a remainder of 724.
Put 4 as the next digit of the answer. 
Result so far: 107129.7564
Subtract 3236 from 3960 to get 724.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7240, and continue the process.

Step 13:
If we divide 7240 by 809, we get 8 and a remainder of 768.
Write down 8 as next digit of the result. 
Result so far: 107129.75648
The remainder is 768 after subtracting 6472 from 7240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7680, and continue the process.

Let's proceed to step 14:
If we divide 7680 by 809, we get 9 and a remainder of 399.
Put 9 as the next digit of the answer. 
Result so far: 107129.756489
If we subtract 7281 from 7680, we get 399.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3990, and continue the process.

On to step 15:
When dividing 3990 by 809, we get 4 with a remainder of 754.
The number 4 becomes the next digit in our result. 
Result so far: 107129.7564894
The remainder is 754 after subtracting 3236 from 3990.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7540, and continue the process.

Let's proceed to step 16:
809 can be fit into 7540 9 times, resulting in a remainder of 259.
Record the quotient 9 as the next digit in the result. 
Result so far: 107129.75648949
Deduct 7281 from 7540 and we're left with 259.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2590, and continue the process.

In conclusion, the division gives 107129.75648949 with a balance of 2.59e-07.
