31387 ÷ 72 
Let's see how many times 72 fits into 31387.

Going ahead to step 1:
72 can be fit into 3 0 times, resulting in a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Take the next digit (1) from the dividend and append it to 3, then repeat: 31 / 72

Advancing to step 2:
When dividing 31 by 72, we get 0 with a remainder of 31.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 31 and we're left with 31.
Take the next digit (3) from the dividend and append it to 31, then repeat: 313 / 72

On to step 3:
The number 72 fits into 313 4 times, leaving a remainder of 25.
The next digit of our result is 4. 
Result so far: 4.0
Subtract 288 from 313 to get 25.
Grab the next digit (8) from the dividend, add it to 25, then carry on: 258 / 72

Going ahead to step 4:
The number 72 fits into 258 3 times, leaving a remainder of 42.
Record the quotient 3 as the next digit in the result. 
Result so far: 43.0
Subtracting 216 from 258 leaves us with 42.
Grab the next digit (7) from the dividend, add it to 42, then carry on: 427 / 72

Step 5:
72 can be fit into 427 5 times, resulting in a remainder of 67.
Write down 5 as next digit of the result. 
Result so far: 435.0
Subtract 360 from 427 to get 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Advancing to step 6:
If we divide 670 by 72, we get 9 and a remainder of 22.
Record the quotient 9 as the next digit in the result. 
Result so far: 435.9
If we subtract 648 from 670, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Going ahead to step 7:
If we divide 220 by 72, we get 3 and a remainder of 4.
The next digit of our result is 3. 
Result so far: 435.93
The remainder is 4 after subtracting 216 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 8:
72 goes into 40 0 times with a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 435.93
Subtract 0 from 40 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 9:
72 can be fit into 400 5 times, resulting in a remainder of 40.
The number 5 becomes the next digit in our result. 
Result so far: 435.9305
Subtracting 360 from 400 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 10:
400 divided by 72 is 5 with a remainder of 40.
The number 5 becomes the next digit in our result. 
Result so far: 435.93055
Subtract 360 from 400 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

The quotient of the division is 435.93055, and the remainder is 4e-05.
