We look at the division of 43274907 by 663 
We're looking to find how many times 663 goes into 43274907.

Moving on to step 1:
663 can be fit into 4 0 times, resulting in a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Include the next digit (3) from the dividend after 4, then repeat: 43 / 663

On to step 2:
The number 663 fits into 43 0 times, leaving a remainder of 43.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 43, we get 43.
Fetch the next digit (2) from the dividend, attach it to 43 and continue: 432 / 663

Let's proceed to step 3:
When dividing 432 by 663, we get 0 with a remainder of 432.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 432 after subtracting 0 from 432.
Append the next digit (7) from the dividend to 432 and continue with: 4327 / 663

Going ahead to step 4:
The number 663 fits into 4327 6 times, leaving a remainder of 349.
Use 6 as the next digit of our solution. 
Result so far: 6.0
Subtract 3978 from 4327 to get 349.
Append the next digit (4) from the dividend to 349 and continue with: 3494 / 663

Moving on to step 5:
3494 divided by 663 is 5 with a remainder of 179.
The number 5 becomes the next digit in our result. 
Result so far: 65.0
The remainder is 179 after subtracting 3315 from 3494.
Append the next digit (9) from the dividend to 179 and continue with: 1799 / 663

On to step 6:
1799 divided by 663 is 2 with a remainder of 473.
The number 2 becomes the next digit in our result. 
Result so far: 652.0
The remainder is 473 after subtracting 1326 from 1799.
Take the next digit (0) from the dividend and append it to 473, then repeat: 4730 / 663

Let's proceed to step 7:
The number 663 fits into 4730 7 times, leaving a remainder of 89.
Put 7 as the next digit of the answer. 
Result so far: 6527.0
Subtract 4641 from 4730 to get 89.
Append the next digit (7) from the dividend to 89 and continue with: 897 / 663

Moving on to step 8:
When dividing 897 by 663, we get 1 with a remainder of 234.
Write down 1 as next digit of the result. 
Result so far: 65271.0
If we subtract 663 from 897, we get 234.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2340, and continue the process.

Step 9:
663 can be fit into 2340 3 times, resulting in a remainder of 351.
The next digit of our result is 3. 
Result so far: 65271.3
The remainder is 351 after subtracting 1989 from 2340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3510, and continue the process.

Step 10:
The number 663 fits into 3510 5 times, leaving a remainder of 195.
Record the quotient 5 as the next digit in the result. 
Result so far: 65271.35
Subtract 3315 from 3510 to get 195.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1950, and continue the process.

Going ahead to step 11:
663 can be fit into 1950 2 times, resulting in a remainder of 624.
Use 2 as the next digit of our solution. 
Result so far: 65271.352
If we subtract 1326 from 1950, we get 624.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6240, and continue the process.

Let's proceed to step 12:
The number 663 fits into 6240 9 times, leaving a remainder of 273.
The next digit of our result is 9. 
Result so far: 65271.3529
Subtracting 5967 from 6240 leaves us with 273.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2730, and continue the process.

On to step 13:
663 goes into 2730 4 times with a remainder of 78.
The number 4 becomes the next digit in our result. 
Result so far: 65271.35294
If we subtract 2652 from 2730, we get 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Step 14:
663 goes into 780 1 times with a remainder of 117.
Use 1 as the next digit of our solution. 
Result so far: 65271.352941
Subtracting 663 from 780 leaves us with 117.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1170, and continue the process.

Step 15:
If we divide 1170 by 663, we get 1 and a remainder of 507.
The number 1 becomes the next digit in our result. 
Result so far: 65271.3529411
If we take 663 away from 1170, we end up with 507.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5070, and continue the process.

The final outcome is 65271.3529411, with a leftover of 5.07e-06.
