We look at the division of 545901 by 5 
We want to figure out the number of times 545901 can be divided by 5.

On to step 1:
5 goes into 5 1 times with a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 5 from 5 and we're left with 0.
Append the next digit (4) from the dividend to 0 and continue with: 4 / 5

Moving on to step 2:
4 divided by 5 is 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 10.0
Subtracting 0 from 4 leaves us with 4.
Take the next digit (5) from the dividend and append it to 4, then repeat: 45 / 5

Moving on to step 3:
5 goes into 45 9 times with a remainder of 0.
Put 9 as the next digit of the answer. 
Result so far: 109.0
Subtracting 45 from 45 leaves us with 0.
Bring next digit (9) of the dividend behind the 0 and repeat the process: 9 / 5

Advancing to step 4:
If we divide 9 by 5, we get 1 and a remainder of 4.
Put 1 as the next digit of the answer. 
Result so far: 1091.0
The remainder is 4 after subtracting 5 from 9.
Take the next digit (0) from the dividend and append it to 4, then repeat: 40 / 5

Going ahead to step 5:
40 divided by 5 is 8 with a remainder of 0.
The number 8 becomes the next digit in our result. 
Result so far: 10918.0
The remainder is 0 after subtracting 40 from 40.
Append the next digit (1) from the dividend to 0 and continue with: 1 / 5

Moving on to step 6:
5 can be fit into 1 0 times, resulting in a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 109180.0
If we take 0 away from 1, 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.

Moving on to step 7:
When dividing 10 by 5, we get 2 with a remainder of 0.
Write down 2 as next digit of the result. 
Result so far: 109180.2
Subtracting 10 from 10 leaves us 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 8:
If we divide 0 by 5, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 109180.2
If we subtract 0 from 0, we 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.

Step 9:
When dividing 0 by 5, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 109180.2
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.

Our division results in 109180.2 with a remaining 0.0.
