373491 ÷ 18 
We want to figure out the number of times 373491 can be divided by 18.

Going ahead to step 1:
If we divide 3 by 18, we get 0 and a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Include the next digit (7) from the dividend after 3, then repeat: 37 / 18

Advancing to step 2:
18 goes into 37 2 times with a remainder of 1.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we subtract 36 from 37, we get 1.
Bring next digit (3) of the dividend behind the 1 and repeat the process: 13 / 18

Moving on to step 3:
13 divided by 18 is 0 with a remainder of 13.
Write down 0 as next digit of the result. 
Result so far: 20.0
The remainder is 13 after subtracting 0 from 13.
Append the next digit (4) from the dividend to 13 and continue with: 134 / 18

Advancing to step 4:
If we divide 134 by 18, we get 7 and a remainder of 8.
Use 7 as the next digit of our solution. 
Result so far: 207.0
Subtract 126 from 134 to get 8.
Grab the next digit (9) from the dividend, add it to 8, then carry on: 89 / 18

Going ahead to step 5:
18 can be fit into 89 4 times, resulting in a remainder of 17.
Record the quotient 4 as the next digit in the result. 
Result so far: 2074.0
Subtract 72 from 89 to get 17.
Grab the next digit (1) from the dividend, add it to 17, then carry on: 171 / 18

Step 6:
18 goes into 171 9 times with a remainder of 9.
Put 9 as the next digit of the answer. 
Result so far: 20749.0
The remainder is 9 after subtracting 162 from 171.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Step 7:
When dividing 90 by 18, we get 5 with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 20749.5
Subtracting 90 from 90 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 8:
0 divided by 18 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 20749.5
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 9:
18 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 20749.5
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 20749.5 and a remainder of 0.0.
