We're dividing 166336 by 72 
We want to divide 166336 by 72.

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.
Grab the next digit (6) from the dividend, add it to 1, then carry on: 16 / 72

Step 2:
16 divided by 72 is 0 with a remainder of 16.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 16, we get 16.
Fetch the next digit (6) from the dividend, attach it to 16 and continue: 166 / 72

Moving on to step 3:
The number 72 fits into 166 2 times, leaving a remainder of 22.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtract 144 from 166 to get 22.
Fetch the next digit (3) from the dividend, attach it to 22 and continue: 223 / 72

Going ahead to step 4:
When dividing 223 by 72, we get 3 with a remainder of 7.
Record the quotient 3 as the next digit in the result. 
Result so far: 23.0
Subtract 216 from 223 to get 7.
Take the next digit (3) from the dividend and append it to 7, then repeat: 73 / 72

Step 5:
The number 72 fits into 73 1 times, leaving a remainder of 1.
Put 1 as the next digit of the answer. 
Result so far: 231.0
If we subtract 72 from 73, we get 1.
Grab the next digit (6) from the dividend, add it to 1, then carry on: 16 / 72

Let's proceed to step 6:
72 goes into 16 0 times with a remainder of 16.
The number 0 becomes the next digit in our result. 
Result so far: 2310.0
The remainder is 16 after subtracting 0 from 16.
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 7:
72 can be fit into 160 2 times, resulting in a remainder of 16.
The number 2 becomes the next digit in our result. 
Result so far: 2310.2
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.

Step 8:
If we divide 160 by 72, we get 2 and a remainder of 16.
Put 2 as the next digit of the answer. 
Result so far: 2310.22
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.

After the division, we end up with 2310.22 and a remainder of 0.016.
