907071 ÷ 66 
We want to figure out the number of times 907071 can be divided by 66.

Step 1:
If we divide 9 by 66, we get 0 and a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Include the next digit (0) from the dividend after 9, then repeat: 90 / 66

Moving on to step 2:
66 goes into 90 1 times with a remainder of 24.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 66 away from 90, we end up with 24.
Grab the next digit (7) from the dividend, add it to 24, then carry on: 247 / 66

Advancing to step 3:
66 can be fit into 247 3 times, resulting in a remainder of 49.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
If we take 198 away from 247, we end up with 49.
Append the next digit (0) from the dividend to 49 and continue with: 490 / 66

On to step 4:
66 goes into 490 7 times with a remainder of 28.
Write down 7 as next digit of the result. 
Result so far: 137.0
Subtracting 462 from 490 leaves us with 28.
Bring next digit (7) of the dividend behind the 28 and repeat the process: 287 / 66

Moving on to step 5:
66 can be fit into 287 4 times, resulting in a remainder of 23.
Record the quotient 4 as the next digit in the result. 
Result so far: 1374.0
If we subtract 264 from 287, we get 23.
Grab the next digit (1) from the dividend, add it to 23, then carry on: 231 / 66

Let's proceed to step 6:
The number 66 fits into 231 3 times, leaving a remainder of 33.
Record the quotient 3 as the next digit in the result. 
Result so far: 13743.0
Subtracting 198 from 231 leaves us with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Moving on to step 7:
66 can be fit into 330 5 times, resulting in a remainder of 0.
The next digit of our result is 5. 
Result so far: 13743.5
Deduct 330 from 330 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 8:
The number 66 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 13743.5
If we subtract 0 from 0, we 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.

Moving on to step 9:
The number 66 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 13743.5
If we take 0 away from 0, we end up 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.

The final outcome is 13743.5, with a leftover of 0.0.
