672835 ÷ 18 
We're looking to find how many times 18 goes into 672835.

Going ahead to step 1:
6 divided by 18 is 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Grab the next digit (7) from the dividend, add it to 6, then carry on: 67 / 18

Going ahead to step 2:
18 goes into 67 3 times with a remainder of 13.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
If we take 54 away from 67, we end up with 13.
Append the next digit (2) from the dividend to 13 and continue with: 132 / 18

Let's proceed to step 3:
The number 18 fits into 132 7 times, leaving a remainder of 6.
Record the quotient 7 as the next digit in the result. 
Result so far: 37.0
Subtract 126 from 132 to get 6.
Grab the next digit (8) from the dividend, add it to 6, then carry on: 68 / 18

Moving on to step 4:
18 goes into 68 3 times with a remainder of 14.
Put 3 as the next digit of the answer. 
Result so far: 373.0
Subtract 54 from 68 to get 14.
Bring next digit (3) of the dividend behind the 14 and repeat the process: 143 / 18

Step 5:
18 can be fit into 143 7 times, resulting in a remainder of 17.
The next digit of our result is 7. 
Result so far: 3737.0
If we subtract 126 from 143, we get 17.
Grab the next digit (5) from the dividend, add it to 17, then carry on: 175 / 18

Going ahead to step 6:
175 divided by 18 is 9 with a remainder of 13.
Put 9 as the next digit of the answer. 
Result so far: 37379.0
Subtracting 162 from 175 leaves us with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Advancing to step 7:
If we divide 130 by 18, we get 7 and a remainder of 4.
Put 7 as the next digit of the answer. 
Result so far: 37379.7
If we subtract 126 from 130, 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.

Going ahead to step 8:
40 divided by 18 is 2 with a remainder of 4.
Put 2 as the next digit of the answer. 
Result so far: 37379.72
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.

Going ahead to step 9:
40 divided by 18 is 2 with a remainder of 4.
Record the quotient 2 as the next digit in the result. 
Result so far: 37379.722
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.

The final outcome is 37379.722, with a leftover of 0.0004.
