105180 ÷ 5 
Let's see how many times 5 fits into 105180.

Going ahead to step 1:
When dividing 1 by 5, we get 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Append the next digit (0) from the dividend to 1 and continue with: 10 / 5

On to step 2:
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: 2.0
If we subtract 10 from 10, we get 0.
Fetch the next digit (5) from the dividend, attach it to 0 and continue: 5 / 5

Going ahead to step 3:
If we divide 5 by 5, we get 1 and a remainder of 0.
The number 1 becomes the next digit in our result. 
Result so far: 21.0
The remainder is 0 after subtracting 5 from 5.
Append the next digit (1) from the dividend to 0 and continue with: 1 / 5

Step 4:
If we divide 1 by 5, we get 0 and a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 210.0
If we subtract 0 from 1, we get 1.
Fetch the next digit (8) from the dividend, attach it to 1 and continue: 18 / 5

Advancing to step 5:
The number 5 fits into 18 3 times, leaving a remainder of 3.
Write down 3 as next digit of the result. 
Result so far: 2103.0
The remainder is 3 after subtracting 15 from 18.
Include the next digit (0) from the dividend after 3, then repeat: 30 / 5

Going ahead to step 6:
The number 5 fits into 30 6 times, leaving a remainder of 0.
Record the quotient 6 as the next digit in the result. 
Result so far: 21036.0
If we subtract 30 from 30, 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.

Moving on to step 7:
5 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 21036.0
Subtracting 0 from 0 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:
5 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 21036.0
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.

After the division, we end up with 21036.0 and a remainder of 0.0.
