165015 ÷ 40 
We want to figure out the number of times 165015 can be divided by 40.

On to step 1:
40 can be fit into 1 0 times, resulting in a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Fetch the next digit (6) from the dividend, attach it to 1 and continue: 16 / 40

Moving on to step 2:
The number 40 fits into 16 0 times, leaving a remainder of 16.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 16 to get 16.
Take the next digit (5) from the dividend and append it to 16, then repeat: 165 / 40

Step 3:
40 can be fit into 165 4 times, resulting in a remainder of 5.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Deduct 160 from 165 and we're left with 5.
Append the next digit (0) from the dividend to 5 and continue with: 50 / 40

Moving on to step 4:
40 goes into 50 1 times with a remainder of 10.
The number 1 becomes the next digit in our result. 
Result so far: 41.0
The remainder is 10 after subtracting 40 from 50.
Bring next digit (1) of the dividend behind the 10 and repeat the process: 101 / 40

Going ahead to step 5:
40 can be fit into 101 2 times, resulting in a remainder of 21.
Put 2 as the next digit of the answer. 
Result so far: 412.0
Subtracting 80 from 101 leaves us with 21.
Grab the next digit (5) from the dividend, add it to 21, then carry on: 215 / 40

Advancing to step 6:
40 can be fit into 215 5 times, resulting in a remainder of 15.
The next digit of our result is 5. 
Result so far: 4125.0
Subtract 200 from 215 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 7:
40 can be fit into 150 3 times, resulting in a remainder of 30.
Record the quotient 3 as the next digit in the result. 
Result so far: 4125.3
Deduct 120 from 150 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 8:
40 can be fit into 300 7 times, resulting in a remainder of 20.
The number 7 becomes the next digit in our result. 
Result so far: 4125.37
Subtracting 280 from 300 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 9:
40 can be fit into 200 5 times, resulting in a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 4125.375
The remainder is 0 after subtracting 200 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 10:
0 divided by 40 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 4125.375
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.

On to step 11:
If we divide 0 by 40, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 4125.375
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 4125.375 and a remainder of 0.0.
