We divide 166535 by 72
We're looking to find how many times 72 goes into 166535.

On to step 1:
72 goes into 1 0 times with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Grab the next digit (6) from the dividend, add it to 1, then carry on: 16 / 72

Moving on to step 2:
72 can be fit into 16 0 times, resulting in a remainder of 16.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 16, we get 16.
Grab the next digit (6) from the dividend, add it to 16, then carry on: 166 / 72

Step 3:
If we divide 166 by 72, we get 2 and a remainder of 22.
Write down 2 as next digit of the result. 
Result so far: 2.0
The remainder is 22 after subtracting 144 from 166.
Grab the next digit (5) from the dividend, add it to 22, then carry on: 225 / 72

Advancing to step 4:
When dividing 225 by 72, we get 3 with a remainder of 9.
Use 3 as the next digit of our solution. 
Result so far: 23.0
If we subtract 216 from 225, we get 9.
Grab the next digit (3) from the dividend, add it to 9, then carry on: 93 / 72

Moving on to step 5:
If we divide 93 by 72, we get 1 and a remainder of 21.
Use 1 as the next digit of our solution. 
Result so far: 231.0
Subtracting 72 from 93 leaves us with 21.
Include the next digit (5) from the dividend after 21, then repeat: 215 / 72

On to step 6:
215 divided by 72 is 2 with a remainder of 71.
The next digit of our result is 2. 
Result so far: 2312.0
If we subtract 144 from 215, we get 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Moving on to step 7:
If we divide 710 by 72, we get 9 and a remainder of 62.
The number 9 becomes the next digit in our result. 
Result so far: 2312.9
The remainder is 62 after subtracting 648 from 710.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

On to step 8:
When dividing 620 by 72, we get 8 with a remainder of 44.
Put 8 as the next digit of the answer. 
Result so far: 2312.98
If we subtract 576 from 620, we get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

On to step 9:
When dividing 440 by 72, we get 6 with a remainder of 8.
The number 6 becomes the next digit in our result. 
Result so far: 2312.986
The remainder is 8 after subtracting 432 from 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 10:
The number 72 fits into 80 1 times, leaving a remainder of 8.
The number 1 becomes the next digit in our result. 
Result so far: 2312.9861
Subtracting 72 from 80 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 11:
When dividing 80 by 72, we get 1 with a remainder of 8.
Record the quotient 1 as the next digit in the result. 
Result so far: 2312.98611
If we subtract 72 from 80, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

After the division, we end up with 2312.98611 and a remainder of 8e-06.
