312023 divided by 72 
Let's see how many times 72 fits into 312023.

On to step 1:
When dividing 3 by 72, we get 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Grab the next digit (1) from the dividend, add it to 3, then carry on: 31 / 72

Moving on to step 2:
72 can be fit into 31 0 times, resulting in a remainder of 31.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 31 and we're left with 31.
Append the next digit (2) from the dividend to 31 and continue with: 312 / 72

Going ahead to step 3:
The number 72 fits into 312 4 times, leaving a remainder of 24.
Write down 4 as next digit of the result. 
Result so far: 4.0
Subtracting 288 from 312 leaves us with 24.
Fetch the next digit (0) from the dividend, attach it to 24 and continue: 240 / 72

On to step 4:
240 divided by 72 is 3 with a remainder of 24.
Use 3 as the next digit of our solution. 
Result so far: 43.0
Subtracting 216 from 240 leaves us with 24.
Fetch the next digit (2) from the dividend, attach it to 24 and continue: 242 / 72

On to step 5:
242 divided by 72 is 3 with a remainder of 26.
The next digit of our result is 3. 
Result so far: 433.0
If we take 216 away from 242, we end up with 26.
Bring next digit (3) of the dividend behind the 26 and repeat the process: 263 / 72

Moving on to step 6:
The number 72 fits into 263 3 times, leaving a remainder of 47.
Record the quotient 3 as the next digit in the result. 
Result so far: 4333.0
Subtracting 216 from 263 leaves us with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

On to step 7:
72 goes into 470 6 times with a remainder of 38.
The next digit of our result is 6. 
Result so far: 4333.6
The remainder is 38 after subtracting 432 from 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Step 8:
380 divided by 72 is 5 with a remainder of 20.
The next digit of our result is 5. 
Result so far: 4333.65
Deduct 360 from 380 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 9:
If we divide 200 by 72, we get 2 and a remainder of 56.
Write down 2 as next digit of the result. 
Result so far: 4333.652
If we subtract 144 from 200, we get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Step 10:
The number 72 fits into 560 7 times, leaving a remainder of 56.
Record the quotient 7 as the next digit in the result. 
Result so far: 4333.6527
If we subtract 504 from 560, we get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Let's proceed to step 11:
The number 72 fits into 560 7 times, leaving a remainder of 56.
The next digit of our result is 7. 
Result so far: 4333.65277
Subtracting 504 from 560 leaves us with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

The quotient of the division is 4333.65277, and the remainder is 5.6e-05.
