161409 divided by 18 
Our goal is to divide 161409 by 18.

Moving on to step 1:
When dividing 1 by 18, we get 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Take the next digit (6) from the dividend and append it to 1, then repeat: 16 / 18

Let's proceed to step 2:
If we divide 16 by 18, we get 0 and a remainder of 16.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 16 after subtracting 0 from 16.
Grab the next digit (1) from the dividend, add it to 16, then carry on: 161 / 18

On to step 3:
If we divide 161 by 18, we get 8 and a remainder of 17.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Subtract 144 from 161 to get 17.
Take the next digit (4) from the dividend and append it to 17, then repeat: 174 / 18

On to step 4:
If we divide 174 by 18, we get 9 and a remainder of 12.
Write down 9 as next digit of the result. 
Result so far: 89.0
Deduct 162 from 174 and we're left with 12.
Grab the next digit (0) from the dividend, add it to 12, then carry on: 120 / 18

Let's proceed to step 5:
If we divide 120 by 18, we get 6 and a remainder of 12.
Use 6 as the next digit of our solution. 
Result so far: 896.0
If we subtract 108 from 120, we get 12.
Include the next digit (9) from the dividend after 12, then repeat: 129 / 18

On to step 6:
If we divide 129 by 18, we get 7 and a remainder of 3.
Write down 7 as next digit of the result. 
Result so far: 8967.0
Subtracting 126 from 129 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 7:
If we divide 30 by 18, we get 1 and a remainder of 12.
Put 1 as the next digit of the answer. 
Result so far: 8967.1
Deduct 18 from 30 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 8:
If we divide 120 by 18, we get 6 and a remainder of 12.
Record the quotient 6 as the next digit in the result. 
Result so far: 8967.16
Subtracting 108 from 120 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 9:
120 divided by 18 is 6 with a remainder of 12.
The number 6 becomes the next digit in our result. 
Result so far: 8967.166
Deduct 108 from 120 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

The final result is 8967.166 with a remainder of 0.0012.
