We divide 393673 by 1
We want to figure out the number of times 393673 can be divided by 1.

On to step 1:
If we divide 3 by 1, we get 3 and a remainder of 0.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtracting 3 from 3 leaves us with 0.
Bring next digit (9) of the dividend behind the 0 and repeat the process: 9 / 1

Going ahead to step 2:
If we divide 9 by 1, we get 9 and a remainder of 0.
The number 9 becomes the next digit in our result. 
Result so far: 39.0
Subtract 9 from 9 to get 0.
Take the next digit (3) from the dividend and append it to 0, then repeat: 3 / 1

On to step 3:
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: 393.0
If we subtract 3 from 3, we get 0.
Bring next digit (6) of the dividend behind the 0 and repeat the process: 6 / 1

Going ahead to step 4:
When dividing 6 by 1, we get 6 with a remainder of 0.
Record the quotient 6 as the next digit in the result. 
Result so far: 3936.0
If we take 6 away from 6, we end up with 0.
Include the next digit (7) from the dividend after 0, then repeat: 7 / 1

Moving on to step 5:
The number 1 fits into 7 7 times, leaving a remainder of 0.
Write down 7 as next digit of the result. 
Result so far: 39367.0
Deduct 7 from 7 and we're left with 0.
Grab the next digit (3) from the dividend, add it to 0, then carry on: 3 / 1

Going ahead to step 6:
When dividing 3 by 1, we get 3 with a remainder of 0.
Write down 3 as next digit of the result. 
Result so far: 393673.0
Deduct 3 from 3 and we're left 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.

On to step 7:
0 divided by 1 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 393673.0
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.

Advancing to step 8:
The number 1 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 393673.0
Deduct 0 from 0 and we're left 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.

In conclusion, the division gives 393673.0 with a balance of 0.0.
