388669 ÷ 72 
We're looking to find how many times 72 goes into 388669.

On to step 1:
If we divide 3 by 72, we get 0 and a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Take the next digit (8) from the dividend and append it to 3, then repeat: 38 / 72

Moving on to step 2:
The number 72 fits into 38 0 times, leaving a remainder of 38.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 38 after subtracting 0 from 38.
Include the next digit (8) from the dividend after 38, then repeat: 388 / 72

Advancing to step 3:
72 goes into 388 5 times with a remainder of 28.
Use 5 as the next digit of our solution. 
Result so far: 5.0
Deduct 360 from 388 and we're left with 28.
Append the next digit (6) from the dividend to 28 and continue with: 286 / 72

Moving on to step 4:
72 can be fit into 286 3 times, resulting in a remainder of 70.
Use 3 as the next digit of our solution. 
Result so far: 53.0
If we subtract 216 from 286, we get 70.
Take the next digit (6) from the dividend and append it to 70, then repeat: 706 / 72

Advancing to step 5:
72 can be fit into 706 9 times, resulting in a remainder of 58.
The next digit of our result is 9. 
Result so far: 539.0
If we take 648 away from 706, we end up with 58.
Append the next digit (9) from the dividend to 58 and continue with: 589 / 72

Advancing to step 6:
72 goes into 589 8 times with a remainder of 13.
Use 8 as the next digit of our solution. 
Result so far: 5398.0
Subtract 576 from 589 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Moving on to step 7:
When dividing 130 by 72, we get 1 with a remainder of 58.
Record the quotient 1 as the next digit in the result. 
Result so far: 5398.1
If we subtract 72 from 130, we get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Let's proceed to step 8:
580 divided by 72 is 8 with a remainder of 4.
The next digit of our result is 8. 
Result so far: 5398.18
Subtract 576 from 580 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 9:
72 can be fit into 40 0 times, resulting in a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 5398.18
Deduct 0 from 40 and we're left 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.

Going ahead to step 10:
When dividing 400 by 72, we get 5 with a remainder of 40.
The next digit of our result is 5. 
Result so far: 5398.1805
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.

Let's proceed to step 11:
The number 72 fits into 400 5 times, leaving a remainder of 40.
Record the quotient 5 as the next digit in the result. 
Result so far: 5398.18055
If we subtract 360 from 400, we 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.

After the division, we end up with 5398.18055 and a remainder of 4e-05.
