Let's divide 16439 by 72
We want to divide 16439 by 72.

Moving on to step 1:
When dividing 1 by 72, we get 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Take the next digit (6) from the dividend and append it to 1, then repeat: 16 / 72

Step 2:
When dividing 16 by 72, we get 0 with a remainder of 16.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 16 after subtracting 0 from 16.
Append the next digit (4) from the dividend to 16 and continue with: 164 / 72

Step 3:
If we divide 164 by 72, we get 2 and a remainder of 20.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we subtract 144 from 164, we get 20.
Append the next digit (3) from the dividend to 20 and continue with: 203 / 72

Let's proceed to step 4:
When dividing 203 by 72, we get 2 with a remainder of 59.
Record the quotient 2 as the next digit in the result. 
Result so far: 22.0
The remainder is 59 after subtracting 144 from 203.
Take the next digit (9) from the dividend and append it to 59, then repeat: 599 / 72

On to step 5:
When dividing 599 by 72, we get 8 with a remainder of 23.
Put 8 as the next digit of the answer. 
Result so far: 228.0
Deduct 576 from 599 and we're left with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Going ahead to step 6:
The number 72 fits into 230 3 times, leaving a remainder of 14.
Record the quotient 3 as the next digit in the result. 
Result so far: 228.3
Deduct 216 from 230 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 7:
When dividing 140 by 72, we get 1 with a remainder of 68.
Use 1 as the next digit of our solution. 
Result so far: 228.31
If we take 72 away from 140, we end up with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

On to step 8:
If we divide 680 by 72, we get 9 and a remainder of 32.
Write down 9 as next digit of the result. 
Result so far: 228.319
Subtract 648 from 680 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.

Moving on to step 9:
72 goes into 320 4 times with a remainder of 32.
Record the quotient 4 as the next digit in the result. 
Result so far: 228.3194
Deduct 288 from 320 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.

Moving on to step 10:
72 can be fit into 320 4 times, resulting in a remainder of 32.
The number 4 becomes the next digit in our result. 
Result so far: 228.31944
The remainder is 32 after subtracting 288 from 320.
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 228.31944 with a remaining 3.2e-05.
