73258618 divided by 809 
We want to divide 73258618 by 809.

Going ahead to step 1:
When dividing 7 by 809, we get 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Include the next digit (3) from the dividend after 7, then repeat: 73 / 809

Moving on to step 2:
809 can be fit into 73 0 times, resulting in a remainder of 73.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 73, we end up with 73.
Grab the next digit (2) from the dividend, add it to 73, then carry on: 732 / 809

Advancing to step 3:
809 goes into 732 0 times with a remainder of 732.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 732 leaves us with 732.
Append the next digit (5) from the dividend to 732 and continue with: 7325 / 809

Step 4:
809 can be fit into 7325 9 times, resulting in a remainder of 44.
Put 9 as the next digit of the answer. 
Result so far: 9.0
If we subtract 7281 from 7325, we get 44.
Take the next digit (8) from the dividend and append it to 44, then repeat: 448 / 809

Step 5:
809 goes into 448 0 times with a remainder of 448.
Use 0 as the next digit of our solution. 
Result so far: 90.0
If we subtract 0 from 448, we get 448.
Fetch the next digit (6) from the dividend, attach it to 448 and continue: 4486 / 809

Step 6:
809 goes into 4486 5 times with a remainder of 441.
Write down 5 as next digit of the result. 
Result so far: 905.0
Deduct 4045 from 4486 and we're left with 441.
Bring next digit (1) of the dividend behind the 441 and repeat the process: 4411 / 809

Step 7:
When dividing 4411 by 809, we get 5 with a remainder of 366.
Record the quotient 5 as the next digit in the result. 
Result so far: 9055.0
Deduct 4045 from 4411 and we're left with 366.
Grab the next digit (8) from the dividend, add it to 366, then carry on: 3668 / 809

Going ahead to step 8:
The number 809 fits into 3668 4 times, leaving a remainder of 432.
The number 4 becomes the next digit in our result. 
Result so far: 90554.0
Subtract 3236 from 3668 to get 432.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4320, and continue the process.

Step 9:
When dividing 4320 by 809, we get 5 with a remainder of 275.
Write down 5 as next digit of the result. 
Result so far: 90554.5
Subtract 4045 from 4320 to get 275.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2750, and continue the process.

On to step 10:
The number 809 fits into 2750 3 times, leaving a remainder of 323.
Write down 3 as next digit of the result. 
Result so far: 90554.53
If we take 2427 away from 2750, we end up with 323.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3230, and continue the process.

Advancing to step 11:
809 can be fit into 3230 3 times, resulting in a remainder of 803.
The next digit of our result is 3. 
Result so far: 90554.533
Subtract 2427 from 3230 to get 803.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8030, and continue the process.

After the division, we end up with 90554.533 and a remainder of 0.0803.
