We look at the division of 483990 by 26 
We want to figure out the number of times 483990 can be divided by 26.

Advancing to step 1:
26 can be fit into 4 0 times, resulting in a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Append the next digit (8) from the dividend to 4 and continue with: 48 / 26

Advancing to step 2:
If we divide 48 by 26, we get 1 and a remainder of 22.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 26 from 48 to get 22.
Fetch the next digit (3) from the dividend, attach it to 22 and continue: 223 / 26

Moving on to step 3:
The number 26 fits into 223 8 times, leaving a remainder of 15.
Use 8 as the next digit of our solution. 
Result so far: 18.0
If we subtract 208 from 223, we get 15.
Bring next digit (9) of the dividend behind the 15 and repeat the process: 159 / 26

On to step 4:
159 divided by 26 is 6 with a remainder of 3.
The number 6 becomes the next digit in our result. 
Result so far: 186.0
Deduct 156 from 159 and we're left with 3.
Include the next digit (9) from the dividend after 3, then repeat: 39 / 26

Moving on to step 5:
26 goes into 39 1 times with a remainder of 13.
Use 1 as the next digit of our solution. 
Result so far: 1861.0
If we take 26 away from 39, we end up with 13.
Take the next digit (0) from the dividend and append it to 13, then repeat: 130 / 26

On to step 6:
26 goes into 130 5 times with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 18615.0
If we take 130 away from 130, 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.

Going ahead to step 7:
0 divided by 26 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 18615.0
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.

On to step 8:
26 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: 18615.0
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.

Our division results in 18615.0 with a remaining 0.0.
