We're dividing 69855744 by 225 
We want to divide 69855744 by 225.

Step 1:
When dividing 6 by 225, we get 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Grab the next digit (9) from the dividend, add it to 6, then carry on: 69 / 225

Advancing to step 2:
225 can be fit into 69 0 times, resulting in a remainder of 69.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 69 after subtracting 0 from 69.
Include the next digit (8) from the dividend after 69, then repeat: 698 / 225

Advancing to step 3:
The number 225 fits into 698 3 times, leaving a remainder of 23.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Subtract 675 from 698 to get 23.
Include the next digit (5) from the dividend after 23, then repeat: 235 / 225

Going ahead to step 4:
235 divided by 225 is 1 with a remainder of 10.
The number 1 becomes the next digit in our result. 
Result so far: 31.0
The remainder is 10 after subtracting 225 from 235.
Append the next digit (5) from the dividend to 10 and continue with: 105 / 225

On to step 5:
When dividing 105 by 225, we get 0 with a remainder of 105.
The next digit of our result is 0. 
Result so far: 310.0
Subtract 0 from 105 to get 105.
Append the next digit (7) from the dividend to 105 and continue with: 1057 / 225

Advancing to step 6:
When dividing 1057 by 225, we get 4 with a remainder of 157.
Record the quotient 4 as the next digit in the result. 
Result so far: 3104.0
If we subtract 900 from 1057, we get 157.
Take the next digit (4) from the dividend and append it to 157, then repeat: 1574 / 225

On to step 7:
225 can be fit into 1574 6 times, resulting in a remainder of 224.
The next digit of our result is 6. 
Result so far: 31046.0
Subtracting 1350 from 1574 leaves us with 224.
Append the next digit (4) from the dividend to 224 and continue with: 2244 / 225

Going ahead to step 8:
225 can be fit into 2244 9 times, resulting in a remainder of 219.
The next digit of our result is 9. 
Result so far: 310469.0
Subtract 2025 from 2244 to get 219.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2190, and continue the process.

Moving on to step 9:
2190 divided by 225 is 9 with a remainder of 165.
Use 9 as the next digit of our solution. 
Result so far: 310469.9
Subtract 2025 from 2190 to get 165.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1650, and continue the process.

Going ahead to step 10:
225 can be fit into 1650 7 times, resulting in a remainder of 75.
The next digit of our result is 7. 
Result so far: 310469.97
Deduct 1575 from 1650 and we're left 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.

Step 11:
225 goes into 750 3 times with a remainder of 75.
The next digit of our result is 3. 
Result so far: 310469.973
Deduct 675 from 750 and we're left 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.

Going ahead to step 12:
750 divided by 225 is 3 with a remainder of 75.
The next digit of our result is 3. 
Result so far: 310469.9733
If we subtract 675 from 750, we 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.

The quotient of the division is 310469.9733, and the remainder is 0.00075.
