We're dividing 43351 by 72 
We want to figure out the number of times 43351 can be divided by 72.

Moving on to step 1:
4 divided by 72 is 0 with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Take the next digit (3) from the dividend and append it to 4, then repeat: 43 / 72

On to step 2:
72 goes into 43 0 times with a remainder of 43.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 43 leaves us with 43.
Bring next digit (3) of the dividend behind the 43 and repeat the process: 433 / 72

Going ahead to step 3:
If we divide 433 by 72, we get 6 and a remainder of 1.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
Subtracting 432 from 433 leaves us with 1.
Grab the next digit (5) from the dividend, add it to 1, then carry on: 15 / 72

Step 4:
The number 72 fits into 15 0 times, leaving a remainder of 15.
Record the quotient 0 as the next digit in the result. 
Result so far: 60.0
The remainder is 15 after subtracting 0 from 15.
Take the next digit (1) from the dividend and append it to 15, then repeat: 151 / 72

On to step 5:
If we divide 151 by 72, we get 2 and a remainder of 7.
Put 2 as the next digit of the answer. 
Result so far: 602.0
Subtract 144 from 151 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Moving on to step 6:
70 divided by 72 is 0 with a remainder of 70.
Record the quotient 0 as the next digit in the result. 
Result so far: 602.0
If we take 0 away from 70, we end up with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Moving on to step 7:
700 divided by 72 is 9 with a remainder of 52.
The next digit of our result is 9. 
Result so far: 602.09
Subtracting 648 from 700 leaves us 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 8:
520 divided by 72 is 7 with a remainder of 16.
Put 7 as the next digit of the answer. 
Result so far: 602.097
Deduct 504 from 520 and we're left 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.

On to step 9:
When dividing 160 by 72, we get 2 with a remainder of 16.
Put 2 as the next digit of the answer. 
Result so far: 602.0972
The remainder is 16 after subtracting 144 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 10:
When dividing 160 by 72, we get 2 with a remainder of 16.
Write down 2 as next digit of the result. 
Result so far: 602.09722
Deduct 144 from 160 and we're left 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.

Our division results in 602.09722 with a remaining 1.6e-05.
