We divide 86309342 by 809
We're looking to find how many times 809 goes into 86309342.

Going ahead to step 1:
When dividing 8 by 809, we get 0 with 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.
Include the next digit (6) from the dividend after 8, then repeat: 86 / 809

Step 2:
When dividing 86 by 809, we get 0 with a remainder of 86.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 86, we get 86.
Take the next digit (3) from the dividend and append it to 86, then repeat: 863 / 809

Let's proceed to step 3:
If we divide 863 by 809, we get 1 and a remainder of 54.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 54 after subtracting 809 from 863.
Include the next digit (0) from the dividend after 54, then repeat: 540 / 809

Going ahead to step 4:
809 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: 10.0
If we subtract 0 from 540, we get 540.
Take the next digit (9) from the dividend and append it to 540, then repeat: 5409 / 809

Advancing to step 5:
The number 809 fits into 5409 6 times, leaving a remainder of 555.
Record the quotient 6 as the next digit in the result. 
Result so far: 106.0
If we subtract 4854 from 5409, we get 555.
Fetch the next digit (3) from the dividend, attach it to 555 and continue: 5553 / 809

Step 6:
The number 809 fits into 5553 6 times, leaving a remainder of 699.
The next digit of our result is 6. 
Result so far: 1066.0
Subtract 4854 from 5553 to get 699.
Bring next digit (4) of the dividend behind the 699 and repeat the process: 6994 / 809

Going ahead to step 7:
When dividing 6994 by 809, we get 8 with a remainder of 522.
Write down 8 as next digit of the result. 
Result so far: 10668.0
Subtracting 6472 from 6994 leaves us with 522.
Fetch the next digit (2) from the dividend, attach it to 522 and continue: 5222 / 809

Let's proceed to step 8:
The number 809 fits into 5222 6 times, leaving a remainder of 368.
Write down 6 as next digit of the result. 
Result so far: 106686.0
The remainder is 368 after subtracting 4854 from 5222.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

On to step 9:
3680 divided by 809 is 4 with a remainder of 444.
The next digit of our result is 4. 
Result so far: 106686.4
Subtract 3236 from 3680 to get 444.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4440, and continue the process.

Step 10:
809 goes into 4440 5 times with a remainder of 395.
Put 5 as the next digit of the answer. 
Result so far: 106686.45
Deduct 4045 from 4440 and we're left with 395.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3950, and continue the process.

On to step 11:
3950 divided by 809 is 4 with a remainder of 714.
Use 4 as the next digit of our solution. 
Result so far: 106686.454
Subtract 3236 from 3950 to get 714.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7140, and continue the process.

Moving on to step 12:
If we divide 7140 by 809, we get 8 and a remainder of 668.
Record the quotient 8 as the next digit in the result. 
Result so far: 106686.4548
Deduct 6472 from 7140 and we're left with 668.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6680, and continue the process.

Moving on to step 13:
When dividing 6680 by 809, we get 8 with a remainder of 208.
Use 8 as the next digit of our solution. 
Result so far: 106686.45488
If we subtract 6472 from 6680, we get 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

The final outcome is 106686.45488, with a leftover of 0.000208.
