We divide 978454 by 15
We want to figure out the number of times 978454 can be divided by 15.

On to step 1:
When dividing 9 by 15, we get 0 with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Bring next digit (7) of the dividend behind the 9 and repeat the process: 97 / 15

Step 2:
97 divided by 15 is 6 with a remainder of 7.
The next digit of our result is 6. 
Result so far: 6.0
Subtract 90 from 97 to get 7.
Include the next digit (8) from the dividend after 7, then repeat: 78 / 15

Let's proceed to step 3:
78 divided by 15 is 5 with a remainder of 3.
The next digit of our result is 5. 
Result so far: 65.0
If we take 75 away from 78, we end up with 3.
Grab the next digit (4) from the dividend, add it to 3, then carry on: 34 / 15

Advancing to step 4:
When dividing 34 by 15, we get 2 with a remainder of 4.
The number 2 becomes the next digit in our result. 
Result so far: 652.0
Subtracting 30 from 34 leaves us with 4.
Include the next digit (5) from the dividend after 4, then repeat: 45 / 15

Let's proceed to step 5:
When dividing 45 by 15, we get 3 with a remainder of 0.
Write down 3 as next digit of the result. 
Result so far: 6523.0
Subtracting 45 from 45 leaves us with 0.
Grab the next digit (4) from the dividend, add it to 0, then carry on: 4 / 15

Advancing to step 6:
The number 15 fits into 4 0 times, leaving a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 65230.0
Deduct 0 from 4 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.

Moving on to step 7:
The number 15 fits into 40 2 times, leaving a remainder of 10.
The next digit of our result is 2. 
Result so far: 65230.2
If we subtract 30 from 40, we 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.

Moving on to step 8:
The number 15 fits into 100 6 times, leaving a remainder of 10.
The next digit of our result is 6. 
Result so far: 65230.26
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.

Moving on to step 9:
15 can be fit into 100 6 times, resulting in a remainder of 10.
Put 6 as the next digit of the answer. 
Result so far: 65230.266
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.

After the division, we end up with 65230.266 and a remainder of 0.001.
