Let's divide 166311 by 72
We want to divide 166311 by 72.

Let's proceed to step 1:
The number 72 fits into 1 0 times, leaving a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Bring next digit (6) of the dividend behind the 1 and repeat the process: 16 / 72

On to step 2:
If we divide 16 by 72, we get 0 and a remainder of 16.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 16 after subtracting 0 from 16.
Take the next digit (6) from the dividend and append it to 16, then repeat: 166 / 72

Step 3:
166 divided by 72 is 2 with a remainder of 22.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Deduct 144 from 166 and we're left with 22.
Bring next digit (3) of the dividend behind the 22 and repeat the process: 223 / 72

Going ahead to step 4:
72 goes into 223 3 times with a remainder of 7.
Use 3 as the next digit of our solution. 
Result so far: 23.0
Subtract 216 from 223 to get 7.
Grab the next digit (1) from the dividend, add it to 7, then carry on: 71 / 72

Moving on to step 5:
The number 72 fits into 71 0 times, leaving a remainder of 71.
Record the quotient 0 as the next digit in the result. 
Result so far: 230.0
If we take 0 away from 71, we end up with 71.
Take the next digit (1) from the dividend and append it to 71, then repeat: 711 / 72

Advancing to step 6:
72 goes into 711 9 times with a remainder of 63.
Put 9 as the next digit of the answer. 
Result so far: 2309.0
If we subtract 648 from 711, we get 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Advancing to step 7:
When dividing 630 by 72, we get 8 with a remainder of 54.
Put 8 as the next digit of the answer. 
Result so far: 2309.8
Deduct 576 from 630 and we're left with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Going ahead to step 8:
72 can be fit into 540 7 times, resulting in a remainder of 36.
Write down 7 as next digit of the result. 
Result so far: 2309.87
If we take 504 away from 540, we end up with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 9:
72 goes into 360 5 times with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 2309.875
If we subtract 360 from 360, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 10:
When dividing 0 by 72, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 2309.875
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 11:
0 divided by 72 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 2309.875
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 2309.875 and a remainder of 0.0.
