Let's divide 23987731 by 66
We want to divide 23987731 by 66.

Advancing to step 1:
2 divided by 66 is 0 with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Bring next digit (3) of the dividend behind the 2 and repeat the process: 23 / 66

Step 2:
66 goes into 23 0 times with a remainder of 23.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 23, we end up with 23.
Take the next digit (9) from the dividend and append it to 23, then repeat: 239 / 66

Step 3:
When dividing 239 by 66, we get 3 with a remainder of 41.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we subtract 198 from 239, we get 41.
Append the next digit (8) from the dividend to 41 and continue with: 418 / 66

Moving on to step 4:
When dividing 418 by 66, we get 6 with a remainder of 22.
Put 6 as the next digit of the answer. 
Result so far: 36.0
If we subtract 396 from 418, we get 22.
Append the next digit (7) from the dividend to 22 and continue with: 227 / 66

On to step 5:
66 can be fit into 227 3 times, resulting in a remainder of 29.
The number 3 becomes the next digit in our result. 
Result so far: 363.0
Deduct 198 from 227 and we're left with 29.
Append the next digit (7) from the dividend to 29 and continue with: 297 / 66

On to step 6:
66 can be fit into 297 4 times, resulting in a remainder of 33.
Record the quotient 4 as the next digit in the result. 
Result so far: 3634.0
Subtracting 264 from 297 leaves us with 33.
Append the next digit (3) from the dividend to 33 and continue with: 333 / 66

Step 7:
When dividing 333 by 66, we get 5 with a remainder of 3.
Use 5 as the next digit of our solution. 
Result so far: 36345.0
Subtracting 330 from 333 leaves us with 3.
Bring next digit (1) of the dividend behind the 3 and repeat the process: 31 / 66

On to step 8:
66 can be fit into 31 0 times, resulting in a remainder of 31.
Write down 0 as next digit of the result. 
Result so far: 363450.0
If we subtract 0 from 31, we get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Step 9:
When dividing 310 by 66, we get 4 with a remainder of 46.
Put 4 as the next digit of the answer. 
Result so far: 363450.4
Deduct 264 from 310 and we're left with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Advancing to step 10:
If we divide 460 by 66, we get 6 and a remainder of 64.
Use 6 as the next digit of our solution. 
Result so far: 363450.46
Subtracting 396 from 460 leaves us with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

On to step 11:
66 can be fit into 640 9 times, resulting in a remainder of 46.
Use 9 as the next digit of our solution. 
Result so far: 363450.469
If we take 594 away from 640, we end up with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Step 12:
If we divide 460 by 66, we get 6 and a remainder of 64.
Record the quotient 6 as the next digit in the result. 
Result so far: 363450.4696
If we take 396 away from 460, we end up with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Advancing to step 13:
When dividing 640 by 66, we get 9 with a remainder of 46.
Use 9 as the next digit of our solution. 
Result so far: 363450.46969
Subtract 594 from 640 to get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Advancing to step 14:
66 can be fit into 460 6 times, resulting in a remainder of 64.
Put 6 as the next digit of the answer. 
Result so far: 363450.469696
Subtracting 396 from 460 leaves us with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Going ahead to step 15:
When dividing 640 by 66, we get 9 with a remainder of 46.
The next digit of our result is 9. 
Result so far: 363450.4696969
Subtracting 594 from 640 leaves us with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Moving on to step 16:
The number 66 fits into 460 6 times, leaving a remainder of 64.
The number 6 becomes the next digit in our result. 
Result so far: 363450.46969696
If we take 396 away from 460, we end up with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

The quotient of the division is 363450.46969696, and the remainder is 6.4e-08.
