679393 ÷ 18 
We want to divide 679393 by 18.

Going ahead to step 1:
When dividing 6 by 18, we get 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Grab the next digit (7) from the dividend, add it to 6, then carry on: 67 / 18

Let's proceed to step 2:
67 divided by 18 is 3 with a remainder of 13.
The next digit of our result is 3. 
Result so far: 3.0
Subtract 54 from 67 to get 13.
Take the next digit (9) from the dividend and append it to 13, then repeat: 139 / 18

Let's proceed to step 3:
18 goes into 139 7 times with a remainder of 13.
Use 7 as the next digit of our solution. 
Result so far: 37.0
The remainder is 13 after subtracting 126 from 139.
Append the next digit (3) from the dividend to 13 and continue with: 133 / 18

On to step 4:
18 goes into 133 7 times with a remainder of 7.
Put 7 as the next digit of the answer. 
Result so far: 377.0
The remainder is 7 after subtracting 126 from 133.
Bring next digit (9) of the dividend behind the 7 and repeat the process: 79 / 18

On to step 5:
If we divide 79 by 18, we get 4 and a remainder of 7.
The next digit of our result is 4. 
Result so far: 3774.0
If we take 72 away from 79, we end up with 7.
Grab the next digit (3) from the dividend, add it to 7, then carry on: 73 / 18

Let's proceed to step 6:
If we divide 73 by 18, we get 4 and a remainder of 1.
The next digit of our result is 4. 
Result so far: 37744.0
If we take 72 away from 73, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 7:
18 can be fit into 10 0 times, resulting in a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 37744.0
Deduct 0 from 10 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 8:
100 divided by 18 is 5 with a remainder of 10.
The next digit of our result is 5. 
Result so far: 37744.05
Subtract 90 from 100 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 9:
18 goes into 100 5 times with a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 37744.055
Subtracting 90 from 100 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The final outcome is 37744.055, with a leftover of 0.001.
