Let's divide 405879 by 25
Let's see how many times 25 fits into 405879.

Moving on to step 1:
25 goes into 4 0 times with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Grab the next digit (0) from the dividend, add it to 4, then carry on: 40 / 25

Moving on to step 2:
40 divided by 25 is 1 with a remainder of 15.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 25 from 40, we get 15.
Fetch the next digit (5) from the dividend, attach it to 15 and continue: 155 / 25

Step 3:
25 can be fit into 155 6 times, resulting in a remainder of 5.
Write down 6 as next digit of the result. 
Result so far: 16.0
If we subtract 150 from 155, we get 5.
Grab the next digit (8) from the dividend, add it to 5, then carry on: 58 / 25

Going ahead to step 4:
25 goes into 58 2 times with a remainder of 8.
Write down 2 as next digit of the result. 
Result so far: 162.0
If we take 50 away from 58, we end up with 8.
Include the next digit (7) from the dividend after 8, then repeat: 87 / 25

On to step 5:
25 goes into 87 3 times with a remainder of 12.
Put 3 as the next digit of the answer. 
Result so far: 1623.0
If we take 75 away from 87, we end up with 12.
Grab the next digit (9) from the dividend, add it to 12, then carry on: 129 / 25

Moving on to step 6:
When dividing 129 by 25, we get 5 with a remainder of 4.
Use 5 as the next digit of our solution. 
Result so far: 16235.0
If we subtract 125 from 129, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 7:
When dividing 40 by 25, we get 1 with a remainder of 15.
Record the quotient 1 as the next digit in the result. 
Result so far: 16235.1
Deduct 25 from 40 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 8:
The number 25 fits into 150 6 times, leaving a remainder of 0.
The number 6 becomes the next digit in our result. 
Result so far: 16235.16
Subtract 150 from 150 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.

Going ahead to step 9:
The number 25 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 16235.16
The remainder is 0 after subtracting 0 from 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 10:
If we divide 0 by 25, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 16235.16
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.

After the division, we end up with 16235.16 and a remainder of 0.0.
