We're dividing 66997873 by 225 
Our goal is to divide 66997873 by 225.

On to step 1:
The number 225 fits into 6 0 times, leaving a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Bring next digit (6) of the dividend behind the 6 and repeat the process: 66 / 225

Going ahead to step 2:
225 goes into 66 0 times with a remainder of 66.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 66 after subtracting 0 from 66.
Grab the next digit (9) from the dividend, add it to 66, then carry on: 669 / 225

Advancing to step 3:
225 goes into 669 2 times with a remainder of 219.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we subtract 450 from 669, we get 219.
Include the next digit (9) from the dividend after 219, then repeat: 2199 / 225

On to step 4:
225 can be fit into 2199 9 times, resulting in a remainder of 174.
Put 9 as the next digit of the answer. 
Result so far: 29.0
If we take 2025 away from 2199, we end up with 174.
Bring next digit (7) of the dividend behind the 174 and repeat the process: 1747 / 225

Advancing to step 5:
The number 225 fits into 1747 7 times, leaving a remainder of 172.
Put 7 as the next digit of the answer. 
Result so far: 297.0
Subtracting 1575 from 1747 leaves us with 172.
Fetch the next digit (8) from the dividend, attach it to 172 and continue: 1728 / 225

Let's proceed to step 6:
225 goes into 1728 7 times with a remainder of 153.
The next digit of our result is 7. 
Result so far: 2977.0
If we subtract 1575 from 1728, we get 153.
Grab the next digit (7) from the dividend, add it to 153, then carry on: 1537 / 225

Going ahead to step 7:
1537 divided by 225 is 6 with a remainder of 187.
The number 6 becomes the next digit in our result. 
Result so far: 29776.0
Deduct 1350 from 1537 and we're left with 187.
Append the next digit (3) from the dividend to 187 and continue with: 1873 / 225

Step 8:
When dividing 1873 by 225, we get 8 with a remainder of 73.
Put 8 as the next digit of the answer. 
Result so far: 297768.0
If we take 1800 away from 1873, we end up with 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Advancing to step 9:
225 goes into 730 3 times with a remainder of 55.
Use 3 as the next digit of our solution. 
Result so far: 297768.3
If we take 675 away from 730, we end up with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Going ahead to step 10:
The number 225 fits into 550 2 times, leaving a remainder of 100.
The next digit of our result is 2. 
Result so far: 297768.32
The remainder is 100 after subtracting 450 from 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Going ahead to step 11:
When dividing 1000 by 225, we get 4 with a remainder of 100.
Record the quotient 4 as the next digit in the result. 
Result so far: 297768.324
The remainder is 100 after subtracting 900 from 1000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Going ahead to step 12:
The number 225 fits into 1000 4 times, leaving a remainder of 100.
Use 4 as the next digit of our solution. 
Result so far: 297768.3244
If we subtract 900 from 1000, we get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Our division results in 297768.3244 with a remaining 0.001.
