66630447 ÷ 72 
Let's see how many times 72 fits into 66630447.

Advancing to step 1:
The number 72 fits into 6 0 times, leaving a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Append the next digit (6) from the dividend to 6 and continue with: 66 / 72

Step 2:
When dividing 66 by 72, we get 0 with a remainder of 66.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 66 leaves us with 66.
Include the next digit (6) from the dividend after 66, then repeat: 666 / 72

Let's proceed to step 3:
The number 72 fits into 666 9 times, leaving a remainder of 18.
Use 9 as the next digit of our solution. 
Result so far: 9.0
Subtract 648 from 666 to get 18.
Grab the next digit (3) from the dividend, add it to 18, then carry on: 183 / 72

On to step 4:
If we divide 183 by 72, we get 2 and a remainder of 39.
Use 2 as the next digit of our solution. 
Result so far: 92.0
If we subtract 144 from 183, we get 39.
Grab the next digit (0) from the dividend, add it to 39, then carry on: 390 / 72

Advancing to step 5:
390 divided by 72 is 5 with a remainder of 30.
The next digit of our result is 5. 
Result so far: 925.0
If we take 360 away from 390, we end up with 30.
Append the next digit (4) from the dividend to 30 and continue with: 304 / 72

Let's proceed to step 6:
If we divide 304 by 72, we get 4 and a remainder of 16.
The next digit of our result is 4. 
Result so far: 9254.0
Deduct 288 from 304 and we're left with 16.
Take the next digit (4) from the dividend and append it to 16, then repeat: 164 / 72

Advancing to step 7:
164 divided by 72 is 2 with a remainder of 20.
Put 2 as the next digit of the answer. 
Result so far: 92542.0
Subtracting 144 from 164 leaves us with 20.
Grab the next digit (7) from the dividend, add it to 20, then carry on: 207 / 72

Moving on to step 8:
207 divided by 72 is 2 with a remainder of 63.
The number 2 becomes the next digit in our result. 
Result so far: 925422.0
Subtract 144 from 207 to get 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Let's proceed to step 9:
When dividing 630 by 72, we get 8 with a remainder of 54.
The next digit of our result is 8. 
Result so far: 925422.8
Deduct 576 from 630 and we're left with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Going ahead to step 10:
The number 72 fits into 540 7 times, leaving a remainder of 36.
Record the quotient 7 as the next digit in the result. 
Result so far: 925422.87
If we take 504 away from 540, we end up with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 11:
72 can be fit into 360 5 times, resulting in a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 925422.875
Deduct 360 from 360 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.

On to step 12:
72 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: 925422.875
Subtracting 0 from 0 leaves us 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.

On to step 13:
72 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 925422.875
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 925422.875 with a remainder of 0.0.
