We look at the division of 346849 by 18 
We're looking to find how many times 18 goes into 346849.

Going ahead to step 1:
When dividing 3 by 18, we get 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Take the next digit (4) from the dividend and append it to 3, then repeat: 34 / 18

Step 2:
18 can be fit into 34 1 times, resulting in a remainder of 16.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 18 from 34 and we're left with 16.
Append the next digit (6) from the dividend to 16 and continue with: 166 / 18

Advancing to step 3:
18 goes into 166 9 times with a remainder of 4.
The number 9 becomes the next digit in our result. 
Result so far: 19.0
If we take 162 away from 166, we end up with 4.
Grab the next digit (8) from the dividend, add it to 4, then carry on: 48 / 18

Going ahead to step 4:
18 can be fit into 48 2 times, resulting in a remainder of 12.
Use 2 as the next digit of our solution. 
Result so far: 192.0
The remainder is 12 after subtracting 36 from 48.
Fetch the next digit (4) from the dividend, attach it to 12 and continue: 124 / 18

On to step 5:
18 can be fit into 124 6 times, resulting in a remainder of 16.
Put 6 as the next digit of the answer. 
Result so far: 1926.0
Deduct 108 from 124 and we're left with 16.
Bring next digit (9) of the dividend behind the 16 and repeat the process: 169 / 18

On to step 6:
When dividing 169 by 18, we get 9 with a remainder of 7.
Use 9 as the next digit of our solution. 
Result so far: 19269.0
Deduct 162 from 169 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Step 7:
18 goes into 70 3 times with a remainder of 16.
Put 3 as the next digit of the answer. 
Result so far: 19269.3
Subtract 54 from 70 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 8:
18 goes into 160 8 times with a remainder of 16.
The number 8 becomes the next digit in our result. 
Result so far: 19269.38
Subtracting 144 from 160 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 9:
18 goes into 160 8 times with a remainder of 16.
Record the quotient 8 as the next digit in the result. 
Result so far: 19269.388
If we subtract 144 from 160, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The final result is 19269.388 with a remainder of 0.0016.
