138364 divided by 72 
Our goal is to divide 138364 by 72.

Step 1:
72 can be fit into 1 0 times, resulting in a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Bring next digit (3) of the dividend behind the 1 and repeat the process: 13 / 72

Step 2:
When dividing 13 by 72, we get 0 with a remainder of 13.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 13 leaves us with 13.
Bring next digit (8) of the dividend behind the 13 and repeat the process: 138 / 72

Moving on to step 3:
The number 72 fits into 138 1 times, leaving a remainder of 66.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 72 from 138 to get 66.
Include the next digit (3) from the dividend after 66, then repeat: 663 / 72

Advancing to step 4:
If we divide 663 by 72, we get 9 and a remainder of 15.
Record the quotient 9 as the next digit in the result. 
Result so far: 19.0
If we take 648 away from 663, we end up with 15.
Fetch the next digit (6) from the dividend, attach it to 15 and continue: 156 / 72

Going ahead to step 5:
72 can be fit into 156 2 times, resulting in a remainder of 12.
The number 2 becomes the next digit in our result. 
Result so far: 192.0
Subtract 144 from 156 to get 12.
Include the next digit (4) from the dividend after 12, then repeat: 124 / 72

Going ahead to step 6:
124 divided by 72 is 1 with a remainder of 52.
The next digit of our result is 1. 
Result so far: 1921.0
If we take 72 away from 124, we end up with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

On to step 7:
When dividing 520 by 72, we get 7 with a remainder of 16.
Write down 7 as next digit of the result. 
Result so far: 1921.7
Subtract 504 from 520 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 8:
72 goes into 160 2 times with a remainder of 16.
The number 2 becomes the next digit in our result. 
Result so far: 1921.72
Subtracting 144 from 160 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 9:
72 can be fit into 160 2 times, resulting in a remainder of 16.
Write down 2 as next digit of the result. 
Result so far: 1921.722
If we subtract 144 from 160, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The final outcome is 1921.722, with a leftover of 0.0016.
