We're dividing 213285 by 25 
We want to figure out the number of times 213285 can be divided by 25.

On to step 1:
When dividing 2 by 25, we get 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 25

Going ahead to step 2:
25 goes into 21 0 times with a remainder of 21.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 21 and we're left with 21.
Include the next digit (3) from the dividend after 21, then repeat: 213 / 25

On to step 3:
When dividing 213 by 25, we get 8 with a remainder of 13.
Write down 8 as next digit of the result. 
Result so far: 8.0
The remainder is 13 after subtracting 200 from 213.
Fetch the next digit (2) from the dividend, attach it to 13 and continue: 132 / 25

Moving on to step 4:
If we divide 132 by 25, we get 5 and a remainder of 7.
Write down 5 as next digit of the result. 
Result so far: 85.0
Subtract 125 from 132 to get 7.
Bring next digit (8) of the dividend behind the 7 and repeat the process: 78 / 25

Advancing to step 5:
The number 25 fits into 78 3 times, leaving a remainder of 3.
Use 3 as the next digit of our solution. 
Result so far: 853.0
Deduct 75 from 78 and we're left with 3.
Include the next digit (5) from the dividend after 3, then repeat: 35 / 25

Moving on to step 6:
The number 25 fits into 35 1 times, leaving a remainder of 10.
Put 1 as the next digit of the answer. 
Result so far: 8531.0
If we take 25 away from 35, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 7:
25 goes into 100 4 times with a remainder of 0.
The number 4 becomes the next digit in our result. 
Result so far: 8531.4
If we take 100 away from 100, 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.

Advancing to step 8:
When dividing 0 by 25, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 8531.4
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.

Moving on to step 9:
The number 25 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 8531.4
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.

Our division results in 8531.4 with a remaining 0.0.
