We're dividing 69400176 by 225 
We're looking to find how many times 225 goes into 69400176.

Step 1:
225 can be fit into 6 0 times, resulting in a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Bring next digit (9) of the dividend behind the 6 and repeat the process: 69 / 225

Advancing to step 2:
If we divide 69 by 225, we get 0 and a remainder of 69.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 69, we end up with 69.
Bring next digit (4) of the dividend behind the 69 and repeat the process: 694 / 225

Going ahead to step 3:
225 goes into 694 3 times with a remainder of 19.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
If we take 675 away from 694, we end up with 19.
Bring next digit (0) of the dividend behind the 19 and repeat the process: 190 / 225

Moving on to step 4:
If we divide 190 by 225, we get 0 and a remainder of 190.
Use 0 as the next digit of our solution. 
Result so far: 30.0
Deduct 0 from 190 and we're left with 190.
Take the next digit (0) from the dividend and append it to 190, then repeat: 1900 / 225

Going ahead to step 5:
1900 divided by 225 is 8 with a remainder of 100.
Use 8 as the next digit of our solution. 
Result so far: 308.0
Deduct 1800 from 1900 and we're left with 100.
Grab the next digit (1) from the dividend, add it to 100, then carry on: 1001 / 225

Going ahead to step 6:
If we divide 1001 by 225, we get 4 and a remainder of 101.
Write down 4 as next digit of the result. 
Result so far: 3084.0
Subtracting 900 from 1001 leaves us with 101.
Include the next digit (7) from the dividend after 101, then repeat: 1017 / 225

Going ahead to step 7:
1017 divided by 225 is 4 with a remainder of 117.
The next digit of our result is 4. 
Result so far: 30844.0
The remainder is 117 after subtracting 900 from 1017.
Grab the next digit (6) from the dividend, add it to 117, then carry on: 1176 / 225

Moving on to step 8:
If we divide 1176 by 225, we get 5 and a remainder of 51.
The number 5 becomes the next digit in our result. 
Result so far: 308445.0
If we subtract 1125 from 1176, we get 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Going ahead to step 9:
When dividing 510 by 225, we get 2 with a remainder of 60.
Record the quotient 2 as the next digit in the result. 
Result so far: 308445.2
Subtracting 450 from 510 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 10:
225 can be fit into 600 2 times, resulting in a remainder of 150.
The next digit of our result is 2. 
Result so far: 308445.22
If we take 450 away from 600, we end up with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

The quotient of the division is 308445.22, and the remainder is 0.15.
