Let's divide 66688431 by 288
Our goal is to divide 66688431 by 288.

On to step 1:
288 can be fit into 6 0 times, resulting in a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Bring next digit (6) of the dividend behind the 6 and repeat the process: 66 / 288

Moving on to step 2:
288 can be fit into 66 0 times, resulting in a remainder of 66.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 66 after subtracting 0 from 66.
Append the next digit (6) from the dividend to 66 and continue with: 666 / 288

Let's proceed to step 3:
The number 288 fits into 666 2 times, leaving a remainder of 90.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we subtract 576 from 666, we get 90.
Fetch the next digit (8) from the dividend, attach it to 90 and continue: 908 / 288

On to step 4:
288 goes into 908 3 times with a remainder of 44.
Record the quotient 3 as the next digit in the result. 
Result so far: 23.0
Deduct 864 from 908 and we're left with 44.
Take the next digit (8) from the dividend and append it to 44, then repeat: 448 / 288

Moving on to step 5:
If we divide 448 by 288, we get 1 and a remainder of 160.
Record the quotient 1 as the next digit in the result. 
Result so far: 231.0
Subtract 288 from 448 to get 160.
Bring next digit (4) of the dividend behind the 160 and repeat the process: 1604 / 288

Going ahead to step 6:
288 can be fit into 1604 5 times, resulting in a remainder of 164.
The next digit of our result is 5. 
Result so far: 2315.0
Subtracting 1440 from 1604 leaves us with 164.
Fetch the next digit (3) from the dividend, attach it to 164 and continue: 1643 / 288

Advancing to step 7:
The number 288 fits into 1643 5 times, leaving a remainder of 203.
Record the quotient 5 as the next digit in the result. 
Result so far: 23155.0
Subtracting 1440 from 1643 leaves us with 203.
Take the next digit (1) from the dividend and append it to 203, then repeat: 2031 / 288

On to step 8:
288 goes into 2031 7 times with a remainder of 15.
Record the quotient 7 as the next digit in the result. 
Result so far: 231557.0
If we take 2016 away from 2031, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 9:
The number 288 fits into 150 0 times, leaving a remainder of 150.
Write down 0 as next digit of the result. 
Result so far: 231557.0
If we take 0 away from 150, we end up with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Moving on to step 10:
The number 288 fits into 1500 5 times, leaving a remainder of 60.
Record the quotient 5 as the next digit in the result. 
Result so far: 231557.05
Subtracting 1440 from 1500 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 11:
288 goes into 600 2 times with a remainder of 24.
The number 2 becomes the next digit in our result. 
Result so far: 231557.052
If we take 576 away from 600, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 12:
If we divide 240 by 288, we get 0 and a remainder of 240.
The number 0 becomes the next digit in our result. 
Result so far: 231557.052
Subtracting 0 from 240 leaves us with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Step 13:
If we divide 2400 by 288, we get 8 and a remainder of 96.
Write down 8 as next digit of the result. 
Result so far: 231557.05208
Subtract 2304 from 2400 to get 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

On to step 14:
288 goes into 960 3 times with a remainder of 96.
Record the quotient 3 as the next digit in the result. 
Result so far: 231557.052083
Subtract 864 from 960 to get 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

On to step 15:
960 divided by 288 is 3 with a remainder of 96.
Record the quotient 3 as the next digit in the result. 
Result so far: 231557.0520833
The remainder is 96 after subtracting 864 from 960.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

In conclusion, the division gives 231557.0520833 with a balance of 9.6e-07.
