We divide 390001 by 5
We want to figure out the number of times 390001 can be divided by 5.

Moving on to step 1:
5 can be fit into 3 0 times, resulting in a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Take the next digit (9) from the dividend and append it to 3, then repeat: 39 / 5

Moving on to step 2:
5 can be fit into 39 7 times, resulting in a remainder of 4.
The next digit of our result is 7. 
Result so far: 7.0
Subtracting 35 from 39 leaves us with 4.
Include the next digit (0) from the dividend after 4, then repeat: 40 / 5

On to step 3:
The number 5 fits into 40 8 times, leaving a remainder of 0.
Put 8 as the next digit of the answer. 
Result so far: 78.0
Deduct 40 from 40 and we're left with 0.
Grab the next digit (0) from the dividend, add it to 0, then carry on: 0 / 5

Moving on to step 4:
When dividing 0 by 5, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 780.0
If we subtract 0 from 0, we get 0.
Bring next digit (0) of the dividend behind the 0 and repeat the process: 0 / 5

Moving on to step 5:
If we divide 0 by 5, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 7800.0
Subtracting 0 from 0 leaves us with 0.
Include the next digit (1) from the dividend after 0, then repeat: 1 / 5

Going ahead to step 6:
If we divide 1 by 5, we get 0 and a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 78000.0
Deduct 0 from 1 and we're left 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.

Going ahead to step 7:
If we divide 10 by 5, we get 2 and a remainder of 0.
Use 2 as the next digit of our solution. 
Result so far: 78000.2
The remainder is 0 after subtracting 10 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 8:
0 divided by 5 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 78000.2
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.

Moving on to step 9:
5 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 78000.2
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 78000.2, with a leftover of 0.0.
