We look at the division of 54285366 by 225 
We want to figure out the number of times 54285366 can be divided by 225.

Moving on to step 1:
5 divided by 225 is 0 with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Grab the next digit (4) from the dividend, add it to 5, then carry on: 54 / 225

Let's proceed to step 2:
54 divided by 225 is 0 with a remainder of 54.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 54, we get 54.
Take the next digit (2) from the dividend and append it to 54, then repeat: 542 / 225

Advancing to step 3:
225 can be fit into 542 2 times, resulting in a remainder of 92.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we take 450 away from 542, we end up with 92.
Grab the next digit (8) from the dividend, add it to 92, then carry on: 928 / 225

Advancing to step 4:
The number 225 fits into 928 4 times, leaving a remainder of 28.
The next digit of our result is 4. 
Result so far: 24.0
If we take 900 away from 928, we end up with 28.
Grab the next digit (5) from the dividend, add it to 28, then carry on: 285 / 225

Step 5:
225 can be fit into 285 1 times, resulting in a remainder of 60.
The next digit of our result is 1. 
Result so far: 241.0
Subtract 225 from 285 to get 60.
Fetch the next digit (3) from the dividend, attach it to 60 and continue: 603 / 225

On to step 6:
When dividing 603 by 225, we get 2 with a remainder of 153.
Write down 2 as next digit of the result. 
Result so far: 2412.0
If we subtract 450 from 603, we get 153.
Grab the next digit (6) from the dividend, add it to 153, then carry on: 1536 / 225

Step 7:
1536 divided by 225 is 6 with a remainder of 186.
Use 6 as the next digit of our solution. 
Result so far: 24126.0
If we subtract 1350 from 1536, we get 186.
Grab the next digit (6) from the dividend, add it to 186, then carry on: 1866 / 225

On to step 8:
225 can be fit into 1866 8 times, resulting in a remainder of 66.
Record the quotient 8 as the next digit in the result. 
Result so far: 241268.0
Deduct 1800 from 1866 and we're left with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

On to step 9:
If we divide 660 by 225, we get 2 and a remainder of 210.
Put 2 as the next digit of the answer. 
Result so far: 241268.2
Deduct 450 from 660 and we're left with 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Step 10:
The number 225 fits into 2100 9 times, leaving a remainder of 75.
Put 9 as the next digit of the answer. 
Result so far: 241268.29
Subtract 2025 from 2100 to get 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Advancing to step 11:
When dividing 750 by 225, we get 3 with a remainder of 75.
Put 3 as the next digit of the answer. 
Result so far: 241268.293
If we take 675 away from 750, we end up with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Advancing to step 12:
225 goes into 750 3 times with a remainder of 75.
The number 3 becomes the next digit in our result. 
Result so far: 241268.2933
If we take 675 away from 750, we end up with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

The final result is 241268.2933 with a remainder of 0.00075.
