We're dividing 311257 by 72 
We're looking to find how many times 72 goes into 311257.

Going ahead to step 1:
The number 72 fits into 3 0 times, leaving a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Include the next digit (1) from the dividend after 3, then repeat: 31 / 72

Let's proceed to step 2:
The number 72 fits into 31 0 times, leaving a remainder of 31.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 31 and we're left with 31.
Include the next digit (1) from the dividend after 31, then repeat: 311 / 72

Moving on to step 3:
72 goes into 311 4 times with a remainder of 23.
The next digit of our result is 4. 
Result so far: 4.0
The remainder is 23 after subtracting 288 from 311.
Append the next digit (2) from the dividend to 23 and continue with: 232 / 72

Advancing to step 4:
When dividing 232 by 72, we get 3 with a remainder of 16.
Record the quotient 3 as the next digit in the result. 
Result so far: 43.0
Deduct 216 from 232 and we're left with 16.
Bring next digit (5) of the dividend behind the 16 and repeat the process: 165 / 72

Moving on to step 5:
72 goes into 165 2 times with a remainder of 21.
Write down 2 as next digit of the result. 
Result so far: 432.0
Subtract 144 from 165 to get 21.
Grab the next digit (7) from the dividend, add it to 21, then carry on: 217 / 72

Step 6:
The number 72 fits into 217 3 times, leaving a remainder of 1.
The next digit of our result is 3. 
Result so far: 4323.0
If we subtract 216 from 217, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 7:
72 can be fit into 10 0 times, resulting in a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 4323.0
If we take 0 away from 10, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 8:
The number 72 fits into 100 1 times, leaving a remainder of 28.
Write down 1 as next digit of the result. 
Result so far: 4323.01
If we subtract 72 from 100, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Advancing to step 9:
If we divide 280 by 72, we get 3 and a remainder of 64.
Put 3 as the next digit of the answer. 
Result so far: 4323.013
The remainder is 64 after subtracting 216 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Moving on to step 10:
If we divide 640 by 72, we get 8 and a remainder of 64.
Record the quotient 8 as the next digit in the result. 
Result so far: 4323.0138
Subtract 576 from 640 to get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Step 11:
The number 72 fits into 640 8 times, leaving a remainder of 64.
Put 8 as the next digit of the answer. 
Result so far: 4323.01388
If we subtract 576 from 640, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

After the division, we end up with 4323.01388 and a remainder of 6.4e-05.
