We divide 45102 by 25
Let's see how many times 25 fits into 45102.

Advancing to step 1:
If we divide 4 by 25, we get 0 and a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Bring next digit (5) of the dividend behind the 4 and repeat the process: 45 / 25

Going ahead to step 2:
The number 25 fits into 45 1 times, leaving a remainder of 20.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 25 from 45 leaves us with 20.
Grab the next digit (1) from the dividend, add it to 20, then carry on: 201 / 25

Going ahead to step 3:
The number 25 fits into 201 8 times, leaving a remainder of 1.
Put 8 as the next digit of the answer. 
Result so far: 18.0
Subtracting 200 from 201 leaves us with 1.
Take the next digit (0) from the dividend and append it to 1, then repeat: 10 / 25

On to step 4:
25 can be fit into 10 0 times, resulting in a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 180.0
Subtracting 0 from 10 leaves us with 10.
Include the next digit (2) from the dividend after 10, then repeat: 102 / 25

Advancing to step 5:
102 divided by 25 is 4 with a remainder of 2.
Write down 4 as next digit of the result. 
Result so far: 1804.0
Deduct 100 from 102 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 6:
If we divide 20 by 25, we get 0 and a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 1804.0
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 7:
200 divided by 25 is 8 with a remainder of 0.
The next digit of our result is 8. 
Result so far: 1804.08
Deduct 200 from 200 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.

Advancing to step 8:
25 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 1804.08
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.

On to step 9:
0 divided by 25 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 1804.08
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.

The quotient of the division is 1804.08, and the remainder is 0.0.
