397686 divided by 72 
We want to divide 397686 by 72.

Moving on to step 1:
3 divided by 72 is 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Include the next digit (9) from the dividend after 3, then repeat: 39 / 72

Advancing to step 2:
72 can be fit into 39 0 times, resulting in a remainder of 39.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 39 and we're left with 39.
Bring next digit (7) of the dividend behind the 39 and repeat the process: 397 / 72

Step 3:
72 can be fit into 397 5 times, resulting in a remainder of 37.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
Subtracting 360 from 397 leaves us with 37.
Append the next digit (6) from the dividend to 37 and continue with: 376 / 72

Advancing to step 4:
72 can be fit into 376 5 times, resulting in a remainder of 16.
The next digit of our result is 5. 
Result so far: 55.0
Subtract 360 from 376 to get 16.
Include the next digit (8) from the dividend after 16, then repeat: 168 / 72

Step 5:
If we divide 168 by 72, we get 2 and a remainder of 24.
The next digit of our result is 2. 
Result so far: 552.0
The remainder is 24 after subtracting 144 from 168.
Bring next digit (6) of the dividend behind the 24 and repeat the process: 246 / 72

On to step 6:
72 can be fit into 246 3 times, resulting in a remainder of 30.
The next digit of our result is 3. 
Result so far: 5523.0
If we subtract 216 from 246, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 7:
The number 72 fits into 300 4 times, leaving a remainder of 12.
Use 4 as the next digit of our solution. 
Result so far: 5523.4
Subtracting 288 from 300 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 8:
When dividing 120 by 72, we get 1 with a remainder of 48.
The number 1 becomes the next digit in our result. 
Result so far: 5523.41
Subtracting 72 from 120 leaves us with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

On to step 9:
72 goes into 480 6 times with a remainder of 48.
The number 6 becomes the next digit in our result. 
Result so far: 5523.416
The remainder is 48 after subtracting 432 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Let's proceed to step 10:
72 can be fit into 480 6 times, resulting in a remainder of 48.
Write down 6 as next digit of the result. 
Result so far: 5523.4166
If we take 432 away from 480, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

The final outcome is 5523.4166, with a leftover of 0.00048.
