66577797 divided by 225 
We want to divide 66577797 by 225.

Advancing to step 1:
If we divide 6 by 225, we get 0 and a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Grab the next digit (6) from the dividend, add it to 6, then carry on: 66 / 225

Advancing to step 2:
66 divided by 225 is 0 with a remainder of 66.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 66 and we're left with 66.
Bring next digit (5) of the dividend behind the 66 and repeat the process: 665 / 225

Step 3:
If we divide 665 by 225, we get 2 and a remainder of 215.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we take 450 away from 665, we end up with 215.
Take the next digit (7) from the dividend and append it to 215, then repeat: 2157 / 225

Moving on to step 4:
225 goes into 2157 9 times with a remainder of 132.
Record the quotient 9 as the next digit in the result. 
Result so far: 29.0
If we subtract 2025 from 2157, we get 132.
Bring next digit (7) of the dividend behind the 132 and repeat the process: 1327 / 225

Let's proceed to step 5:
If we divide 1327 by 225, we get 5 and a remainder of 202.
The next digit of our result is 5. 
Result so far: 295.0
If we subtract 1125 from 1327, we get 202.
Append the next digit (7) from the dividend to 202 and continue with: 2027 / 225

Moving on to step 6:
When dividing 2027 by 225, we get 9 with a remainder of 2.
Use 9 as the next digit of our solution. 
Result so far: 2959.0
The remainder is 2 after subtracting 2025 from 2027.
Append the next digit (9) from the dividend to 2 and continue with: 29 / 225

Moving on to step 7:
The number 225 fits into 29 0 times, leaving a remainder of 29.
Use 0 as the next digit of our solution. 
Result so far: 29590.0
If we take 0 away from 29, we end up with 29.
Include the next digit (7) from the dividend after 29, then repeat: 297 / 225

Moving on to step 8:
The number 225 fits into 297 1 times, leaving a remainder of 72.
The next digit of our result is 1. 
Result so far: 295901.0
Subtract 225 from 297 to get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Let's proceed to step 9:
225 goes into 720 3 times with a remainder of 45.
Put 3 as the next digit of the answer. 
Result so far: 295901.3
Deduct 675 from 720 and we're left with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Let's proceed to step 10:
When dividing 450 by 225, we get 2 with a remainder of 0.
The number 2 becomes the next digit in our result. 
Result so far: 295901.32
Subtract 450 from 450 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.

Step 11:
225 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 295901.32
Deduct 0 from 0 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.

Step 12:
225 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 295901.32
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.

The final result is 295901.32 with a remainder of 0.0.
