Let's divide 389387 by 72
Our goal is to divide 389387 by 72.

Advancing to step 1:
When dividing 3 by 72, we get 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Bring next digit (8) of the dividend behind the 3 and repeat the process: 38 / 72

Advancing to step 2:
If we divide 38 by 72, we get 0 and a remainder of 38.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 38, we end up with 38.
Fetch the next digit (9) from the dividend, attach it to 38 and continue: 389 / 72

Moving on to step 3:
If we divide 389 by 72, we get 5 and a remainder of 29.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
Subtracting 360 from 389 leaves us with 29.
Fetch the next digit (3) from the dividend, attach it to 29 and continue: 293 / 72

Let's proceed to step 4:
When dividing 293 by 72, we get 4 with a remainder of 5.
Put 4 as the next digit of the answer. 
Result so far: 54.0
If we take 288 away from 293, we end up with 5.
Take the next digit (8) from the dividend and append it to 5, then repeat: 58 / 72

Going ahead to step 5:
The number 72 fits into 58 0 times, leaving a remainder of 58.
Put 0 as the next digit of the answer. 
Result so far: 540.0
Subtracting 0 from 58 leaves us with 58.
Take the next digit (7) from the dividend and append it to 58, then repeat: 587 / 72

Let's proceed to step 6:
72 goes into 587 8 times with a remainder of 11.
Record the quotient 8 as the next digit in the result. 
Result so far: 5408.0
Deduct 576 from 587 and we're left with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

On to step 7:
72 goes into 110 1 times with a remainder of 38.
Put 1 as the next digit of the answer. 
Result so far: 5408.1
The remainder is 38 after subtracting 72 from 110.
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 number 5 becomes the next digit in our result. 
Result so far: 5408.15
If we take 360 away from 380, we end up 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.

Step 9:
The number 72 fits into 200 2 times, leaving a remainder of 56.
Put 2 as the next digit of the answer. 
Result so far: 5408.152
Subtract 144 from 200 to 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:
72 goes into 560 7 times with a remainder of 56.
Write down 7 as next digit of the result. 
Result so far: 5408.1527
The remainder is 56 after subtracting 504 from 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Moving on to step 11:
72 goes into 560 7 times with a remainder of 56.
Write down 7 as next digit of the result. 
Result so far: 5408.15277
Subtract 504 from 560 to 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.

The final outcome is 5408.15277, with a leftover of 5.6e-05.
