300370 divided by 18 
We want to figure out the number of times 300370 can be divided by 18.

On to step 1:
18 can be fit into 3 0 times, resulting in a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Bring next digit (0) of the dividend behind the 3 and repeat the process: 30 / 18

Going ahead to step 2:
18 goes into 30 1 times with a remainder of 12.
The next digit of our result is 1. 
Result so far: 1.0
If we take 18 away from 30, we end up with 12.
Fetch the next digit (0) from the dividend, attach it to 12 and continue: 120 / 18

Going ahead to step 3:
18 goes into 120 6 times with a remainder of 12.
Put 6 as the next digit of the answer. 
Result so far: 16.0
Subtracting 108 from 120 leaves us with 12.
Append the next digit (3) from the dividend to 12 and continue with: 123 / 18

Going ahead to step 4:
18 goes into 123 6 times with a remainder of 15.
The number 6 becomes the next digit in our result. 
Result so far: 166.0
Deduct 108 from 123 and we're left with 15.
Append the next digit (7) from the dividend to 15 and continue with: 157 / 18

Moving on to step 5:
The number 18 fits into 157 8 times, leaving a remainder of 13.
The number 8 becomes the next digit in our result. 
Result so far: 1668.0
The remainder is 13 after subtracting 144 from 157.
Grab the next digit (0) from the dividend, add it to 13, then carry on: 130 / 18

On to step 6:
The number 18 fits into 130 7 times, leaving a remainder of 4.
Use 7 as the next digit of our solution. 
Result so far: 16687.0
The remainder is 4 after subtracting 126 from 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 7:
18 can be fit into 40 2 times, resulting in a remainder of 4.
The number 2 becomes the next digit in our result. 
Result so far: 16687.2
If we subtract 36 from 40, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 8:
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: 16687.22
If we subtract 36 from 40, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

In conclusion, the division gives 16687.22 with a balance of 0.004.
