We divide 394410 by 1
We want to figure out the number of times 394410 can be divided by 1.

Moving on to step 1:
When dividing 3 by 1, we get 3 with a remainder of 0.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we take 3 away from 3, we end up with 0.
Include the next digit (9) from the dividend after 0, then repeat: 9 / 1

On to step 2:
1 can be fit into 9 9 times, resulting in a remainder of 0.
The number 9 becomes the next digit in our result. 
Result so far: 39.0
If we subtract 9 from 9, we get 0.
Fetch the next digit (4) from the dividend, attach it to 0 and continue: 4 / 1

Step 3:
When dividing 4 by 1, we get 4 with a remainder of 0.
Use 4 as the next digit of our solution. 
Result so far: 394.0
If we subtract 4 from 4, we get 0.
Include the next digit (4) from the dividend after 0, then repeat: 4 / 1

On to step 4:
4 divided by 1 is 4 with a remainder of 0.
The number 4 becomes the next digit in our result. 
Result so far: 3944.0
Subtracting 4 from 4 leaves us with 0.
Grab the next digit (1) from the dividend, add it to 0, then carry on: 1 / 1

Going ahead to step 5:
If we divide 1 by 1, we get 1 and a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 39441.0
The remainder is 0 after subtracting 1 from 1.
Grab the next digit (0) from the dividend, add it to 0, then carry on: 0 / 1

Step 6:
If we divide 0 by 1, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 394410.0
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 7:
1 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 394410.0
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 8:
When dividing 0 by 1, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 394410.0
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 394410.0, with a leftover of 0.0.
