978420 ÷ 18 
We're looking to find how many times 18 goes into 978420.

On to step 1:
When dividing 9 by 18, we get 0 with a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Grab the next digit (7) from the dividend, add it to 9, then carry on: 97 / 18

Going ahead to step 2:
97 divided by 18 is 5 with a remainder of 7.
The next digit of our result is 5. 
Result so far: 5.0
If we subtract 90 from 97, we get 7.
Fetch the next digit (8) from the dividend, attach it to 7 and continue: 78 / 18

Let's proceed to step 3:
The number 18 fits into 78 4 times, leaving a remainder of 6.
The next digit of our result is 4. 
Result so far: 54.0
If we take 72 away from 78, we end up with 6.
Fetch the next digit (4) from the dividend, attach it to 6 and continue: 64 / 18

Step 4:
The number 18 fits into 64 3 times, leaving a remainder of 10.
The number 3 becomes the next digit in our result. 
Result so far: 543.0
The remainder is 10 after subtracting 54 from 64.
Grab the next digit (2) from the dividend, add it to 10, then carry on: 102 / 18

On to step 5:
18 goes into 102 5 times with a remainder of 12.
The number 5 becomes the next digit in our result. 
Result so far: 5435.0
If we take 90 away from 102, we end up with 12.
Take the next digit (0) from the dividend and append it to 12, then repeat: 120 / 18

Advancing to step 6:
The number 18 fits into 120 6 times, leaving a remainder of 12.
Write down 6 as next digit of the result. 
Result so far: 54356.0
Subtract 108 from 120 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 7:
18 goes into 120 6 times with a remainder of 12.
The next digit of our result is 6. 
Result so far: 54356.6
Subtracting 108 from 120 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 8:
18 goes into 120 6 times with a remainder of 12.
Put 6 as the next digit of the answer. 
Result so far: 54356.66
Subtract 108 from 120 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

The final outcome is 54356.66, with a leftover of 0.012.
