We look at the division of 51489104 by 225 
Our goal is to divide 51489104 by 225.

On to step 1:
5 divided by 225 is 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Fetch the next digit (1) from the dividend, attach it to 5 and continue: 51 / 225

On to step 2:
When dividing 51 by 225, we get 0 with a remainder of 51.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 51 leaves us with 51.
Bring next digit (4) of the dividend behind the 51 and repeat the process: 514 / 225

Step 3:
225 can be fit into 514 2 times, resulting in a remainder of 64.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtract 450 from 514 to get 64.
Fetch the next digit (8) from the dividend, attach it to 64 and continue: 648 / 225

Advancing to step 4:
648 divided by 225 is 2 with a remainder of 198.
Record the quotient 2 as the next digit in the result. 
Result so far: 22.0
Subtracting 450 from 648 leaves us with 198.
Grab the next digit (9) from the dividend, add it to 198, then carry on: 1989 / 225

Moving on to step 5:
When dividing 1989 by 225, we get 8 with a remainder of 189.
The next digit of our result is 8. 
Result so far: 228.0
If we subtract 1800 from 1989, we get 189.
Fetch the next digit (1) from the dividend, attach it to 189 and continue: 1891 / 225

Going ahead to step 6:
If we divide 1891 by 225, we get 8 and a remainder of 91.
The next digit of our result is 8. 
Result so far: 2288.0
If we subtract 1800 from 1891, we get 91.
Fetch the next digit (0) from the dividend, attach it to 91 and continue: 910 / 225

Going ahead to step 7:
910 divided by 225 is 4 with a remainder of 10.
Write down 4 as next digit of the result. 
Result so far: 22884.0
If we subtract 900 from 910, we get 10.
Take the next digit (4) from the dividend and append it to 10, then repeat: 104 / 225

Let's proceed to step 8:
When dividing 104 by 225, we get 0 with a remainder of 104.
Put 0 as the next digit of the answer. 
Result so far: 228840.0
The remainder is 104 after subtracting 0 from 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Going ahead to step 9:
225 goes into 1040 4 times with a remainder of 140.
Put 4 as the next digit of the answer. 
Result so far: 228840.4
Subtract 900 from 1040 to get 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

On to step 10:
When dividing 1400 by 225, we get 6 with a remainder of 50.
The number 6 becomes the next digit in our result. 
Result so far: 228840.46
Deduct 1350 from 1400 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 11:
The number 225 fits into 500 2 times, leaving a remainder of 50.
Use 2 as the next digit of our solution. 
Result so far: 228840.462
Subtract 450 from 500 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 12:
If we divide 500 by 225, we get 2 and a remainder of 50.
The number 2 becomes the next digit in our result. 
Result so far: 228840.4622
The remainder is 50 after subtracting 450 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

After the division, we end up with 228840.4622 and a remainder of 0.0005.
