Let's divide 904521 by 5
We want to figure out the number of times 904521 can be divided by 5.

Moving on to step 1:
5 can be fit into 9 1 times, resulting in a remainder of 4.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 5 from 9 and we're left with 4.
Fetch the next digit (0) from the dividend, attach it to 4 and continue: 40 / 5

Moving on to step 2:
5 goes into 40 8 times with a remainder of 0.
Put 8 as the next digit of the answer. 
Result so far: 18.0
Subtracting 40 from 40 leaves us with 0.
Take the next digit (4) from the dividend and append it to 0, then repeat: 4 / 5

On to step 3:
4 divided by 5 is 0 with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 180.0
If we take 0 away from 4, we end up with 4.
Take the next digit (5) from the dividend and append it to 4, then repeat: 45 / 5

Moving on to step 4:
5 can be fit into 45 9 times, resulting in a remainder of 0.
Put 9 as the next digit of the answer. 
Result so far: 1809.0
Subtracting 45 from 45 leaves us with 0.
Bring next digit (2) of the dividend behind the 0 and repeat the process: 2 / 5

Advancing to step 5:
2 divided by 5 is 0 with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 18090.0
If we subtract 0 from 2, we get 2.
Append the next digit (1) from the dividend to 2 and continue with: 21 / 5

Let's proceed to step 6:
21 divided by 5 is 4 with a remainder of 1.
The number 4 becomes the next digit in our result. 
Result so far: 180904.0
If we take 20 away from 21, we end up 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:
The number 5 fits into 10 2 times, leaving a remainder of 0.
Use 2 as the next digit of our solution. 
Result so far: 180904.2
Deduct 10 from 10 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.

Let's proceed to step 8:
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: 180904.2
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.

Step 9:
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: 180904.2
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.

Our division results in 180904.2 with a remaining 0.0.
