13649 ÷ 72 
Let's see how many times 72 fits into 13649.

Advancing to step 1:
If we divide 1 by 72, we get 0 and a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Include the next digit (3) from the dividend after 1, then repeat: 13 / 72

On to step 2:
72 can be fit into 13 0 times, resulting in a remainder of 13.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 13, we get 13.
Take the next digit (6) from the dividend and append it to 13, then repeat: 136 / 72

Moving on to step 3:
136 divided by 72 is 1 with a remainder of 64.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 72 from 136 to get 64.
Bring next digit (4) of the dividend behind the 64 and repeat the process: 644 / 72

Advancing to step 4:
The number 72 fits into 644 8 times, leaving a remainder of 68.
Put 8 as the next digit of the answer. 
Result so far: 18.0
Subtracting 576 from 644 leaves us with 68.
Bring next digit (9) of the dividend behind the 68 and repeat the process: 689 / 72

Step 5:
689 divided by 72 is 9 with a remainder of 41.
Put 9 as the next digit of the answer. 
Result so far: 189.0
If we subtract 648 from 689, we get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Let's proceed to step 6:
The number 72 fits into 410 5 times, leaving a remainder of 50.
Record the quotient 5 as the next digit in the result. 
Result so far: 189.5
Deduct 360 from 410 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 7:
The number 72 fits into 500 6 times, leaving a remainder of 68.
Write down 6 as next digit of the result. 
Result so far: 189.56
The remainder is 68 after subtracting 432 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Advancing to step 8:
72 goes into 680 9 times with a remainder of 32.
The number 9 becomes the next digit in our result. 
Result so far: 189.569
Deduct 648 from 680 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 9:
If we divide 320 by 72, we get 4 and a remainder of 32.
Put 4 as the next digit of the answer. 
Result so far: 189.5694
Subtract 288 from 320 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 10:
72 can be fit into 320 4 times, resulting in a remainder of 32.
Use 4 as the next digit of our solution. 
Result so far: 189.56944
Subtracting 288 from 320 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Our division results in 189.56944 with a remaining 3.2e-05.
