183961 divided by 18 
Let's see how many times 18 fits into 183961.

Moving on to step 1:
18 goes into 1 0 times with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Bring next digit (8) of the dividend behind the 1 and repeat the process: 18 / 18

Going ahead to step 2:
If we divide 18 by 18, we get 1 and a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 18 from 18, we get 0.
Grab the next digit (3) from the dividend, add it to 0, then carry on: 3 / 18

Going ahead to step 3:
3 divided by 18 is 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 10.0
Subtracting 0 from 3 leaves us with 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 18

Step 4:
The number 18 fits into 39 2 times, leaving a remainder of 3.
Use 2 as the next digit of our solution. 
Result so far: 102.0
The remainder is 3 after subtracting 36 from 39.
Fetch the next digit (6) from the dividend, attach it to 3 and continue: 36 / 18

On to step 5:
When dividing 36 by 18, we get 2 with a remainder of 0.
The number 2 becomes the next digit in our result. 
Result so far: 1022.0
If we subtract 36 from 36, we get 0.
Bring next digit (1) of the dividend behind the 0 and repeat the process: 1 / 18

Let's proceed to step 6:
1 divided by 18 is 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 10220.0
If we subtract 0 from 1, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 7:
18 can be fit into 10 0 times, resulting in a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 10220.0
Deduct 0 from 10 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 8:
When dividing 100 by 18, we get 5 with a remainder of 10.
Use 5 as the next digit of our solution. 
Result so far: 10220.05
Deduct 90 from 100 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 9:
The number 18 fits into 100 5 times, leaving a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 10220.055
Subtracting 90 from 100 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The final outcome is 10220.055, with a leftover of 0.001.
