We divide 18015530 by 809
We want to divide 18015530 by 809.

Step 1:
When dividing 1 by 809, we get 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Take the next digit (8) from the dividend and append it to 1, then repeat: 18 / 809

On to step 2:
If we divide 18 by 809, we get 0 and a remainder of 18.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 18 after subtracting 0 from 18.
Fetch the next digit (0) from the dividend, attach it to 18 and continue: 180 / 809

On to step 3:
If we divide 180 by 809, we get 0 and a remainder of 180.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 180 after subtracting 0 from 180.
Bring next digit (1) of the dividend behind the 180 and repeat the process: 1801 / 809

Step 4:
When dividing 1801 by 809, we get 2 with a remainder of 183.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtracting 1618 from 1801 leaves us with 183.
Grab the next digit (5) from the dividend, add it to 183, then carry on: 1835 / 809

Moving on to step 5:
809 goes into 1835 2 times with a remainder of 217.
Put 2 as the next digit of the answer. 
Result so far: 22.0
The remainder is 217 after subtracting 1618 from 1835.
Include the next digit (5) from the dividend after 217, then repeat: 2175 / 809

On to step 6:
When dividing 2175 by 809, we get 2 with a remainder of 557.
Record the quotient 2 as the next digit in the result. 
Result so far: 222.0
Deduct 1618 from 2175 and we're left with 557.
Include the next digit (3) from the dividend after 557, then repeat: 5573 / 809

Let's proceed to step 7:
809 can be fit into 5573 6 times, resulting in a remainder of 719.
Use 6 as the next digit of our solution. 
Result so far: 2226.0
If we take 4854 away from 5573, we end up with 719.
Append the next digit (0) from the dividend to 719 and continue with: 7190 / 809

Let's proceed to step 8:
When dividing 7190 by 809, we get 8 with a remainder of 718.
Put 8 as the next digit of the answer. 
Result so far: 22268.0
Subtracting 6472 from 7190 leaves us with 718.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7180, and continue the process.

Advancing to step 9:
7180 divided by 809 is 8 with a remainder of 708.
The number 8 becomes the next digit in our result. 
Result so far: 22268.8
Deduct 6472 from 7180 and we're left with 708.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7080, and continue the process.

Step 10:
809 goes into 7080 8 times with a remainder of 608.
Record the quotient 8 as the next digit in the result. 
Result so far: 22268.88
The remainder is 608 after subtracting 6472 from 7080.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6080, and continue the process.

Our division results in 22268.88 with a remaining 0.608.
