21234023 divided by 288 
Our goal is to divide 21234023 by 288.

Advancing to step 1:
2 divided by 288 is 0 with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Append the next digit (1) from the dividend to 2 and continue with: 21 / 288

Step 2:
The number 288 fits into 21 0 times, leaving a remainder of 21.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 21 after subtracting 0 from 21.
Grab the next digit (2) from the dividend, add it to 21, then carry on: 212 / 288

Let's proceed to step 3:
The number 288 fits into 212 0 times, leaving a remainder of 212.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 212 after subtracting 0 from 212.
Grab the next digit (3) from the dividend, add it to 212, then carry on: 2123 / 288

Advancing to step 4:
If we divide 2123 by 288, we get 7 and a remainder of 107.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
The remainder is 107 after subtracting 2016 from 2123.
Append the next digit (4) from the dividend to 107 and continue with: 1074 / 288

Step 5:
The number 288 fits into 1074 3 times, leaving a remainder of 210.
Write down 3 as next digit of the result. 
Result so far: 73.0
The remainder is 210 after subtracting 864 from 1074.
Take the next digit (0) from the dividend and append it to 210, then repeat: 2100 / 288

Step 6:
288 can be fit into 2100 7 times, resulting in a remainder of 84.
Record the quotient 7 as the next digit in the result. 
Result so far: 737.0
If we subtract 2016 from 2100, we get 84.
Grab the next digit (2) from the dividend, add it to 84, then carry on: 842 / 288

Going ahead to step 7:
When dividing 842 by 288, we get 2 with a remainder of 266.
Record the quotient 2 as the next digit in the result. 
Result so far: 7372.0
If we take 576 away from 842, we end up with 266.
Bring next digit (3) of the dividend behind the 266 and repeat the process: 2663 / 288

Going ahead to step 8:
The number 288 fits into 2663 9 times, leaving a remainder of 71.
The number 9 becomes the next digit in our result. 
Result so far: 73729.0
If we take 2592 away from 2663, we end up with 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Step 9:
The number 288 fits into 710 2 times, leaving a remainder of 134.
Put 2 as the next digit of the answer. 
Result so far: 73729.2
If we subtract 576 from 710, we get 134.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1340, and continue the process.

Step 10:
When dividing 1340 by 288, we get 4 with a remainder of 188.
The number 4 becomes the next digit in our result. 
Result so far: 73729.24
Subtract 1152 from 1340 to get 188.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1880, and continue the process.

Let's proceed to step 11:
288 goes into 1880 6 times with a remainder of 152.
Use 6 as the next digit of our solution. 
Result so far: 73729.246
The remainder is 152 after subtracting 1728 from 1880.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

Advancing to step 12:
The number 288 fits into 1520 5 times, leaving a remainder of 80.
Record the quotient 5 as the next digit in the result. 
Result so far: 73729.2465
Deduct 1440 from 1520 and we're left with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

On to step 13:
If we divide 800 by 288, we get 2 and a remainder of 224.
Record the quotient 2 as the next digit in the result. 
Result so far: 73729.24652
The remainder is 224 after subtracting 576 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

Let's proceed to step 14:
The number 288 fits into 2240 7 times, leaving a remainder of 224.
The number 7 becomes the next digit in our result. 
Result so far: 73729.246527
Deduct 2016 from 2240 and we're left with 224.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

Step 15:
If we divide 2240 by 288, we get 7 and a remainder of 224.
Record the quotient 7 as the next digit in the result. 
Result so far: 73729.2465277
Subtract 2016 from 2240 to get 224.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

The final result is 73729.2465277 with a remainder of 2.24e-06.
