We're dividing 346945 by 18 
Let's see how many times 18 fits into 346945.

Let's proceed to step 1:
18 goes into 3 0 times with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Bring next digit (4) of the dividend behind the 3 and repeat the process: 34 / 18

Advancing to step 2:
When dividing 34 by 18, we get 1 with a remainder of 16.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 18 from 34 leaves us with 16.
Append the next digit (6) from the dividend to 16 and continue with: 166 / 18

Moving on to step 3:
When dividing 166 by 18, we get 9 with a remainder of 4.
The next digit of our result is 9. 
Result so far: 19.0
Subtract 162 from 166 to get 4.
Include the next digit (9) from the dividend after 4, then repeat: 49 / 18

Going ahead to step 4:
If we divide 49 by 18, we get 2 and a remainder of 13.
Use 2 as the next digit of our solution. 
Result so far: 192.0
Deduct 36 from 49 and we're left with 13.
Include the next digit (4) from the dividend after 13, then repeat: 134 / 18

Let's proceed to step 5:
When dividing 134 by 18, we get 7 with a remainder of 8.
Record the quotient 7 as the next digit in the result. 
Result so far: 1927.0
Deduct 126 from 134 and we're left with 8.
Grab the next digit (5) from the dividend, add it to 8, then carry on: 85 / 18

Step 6:
85 divided by 18 is 4 with a remainder of 13.
Use 4 as the next digit of our solution. 
Result so far: 19274.0
Subtract 72 from 85 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Step 7:
18 goes into 130 7 times with a remainder of 4.
Use 7 as the next digit of our solution. 
Result so far: 19274.7
Subtracting 126 from 130 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 8:
18 can be fit into 40 2 times, resulting in a remainder of 4.
Use 2 as the next digit of our solution. 
Result so far: 19274.72
Deduct 36 from 40 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 9:
When dividing 40 by 18, we get 2 with a remainder of 4.
Record the quotient 2 as the next digit in the result. 
Result so far: 19274.722
Deduct 36 from 40 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

The final outcome is 19274.722, with a leftover of 0.0004.
