We divide 145752 by 40
We want to figure out the number of times 145752 can be divided by 40.

On to step 1:
The number 40 fits into 1 0 times, leaving a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Bring next digit (4) of the dividend behind the 1 and repeat the process: 14 / 40

Step 2:
40 goes into 14 0 times with a remainder of 14.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 14, we end up with 14.
Take the next digit (5) from the dividend and append it to 14, then repeat: 145 / 40

Moving on to step 3:
When dividing 145 by 40, we get 3 with a remainder of 25.
The next digit of our result is 3. 
Result so far: 3.0
Subtracting 120 from 145 leaves us with 25.
Include the next digit (7) from the dividend after 25, then repeat: 257 / 40

Moving on to step 4:
When dividing 257 by 40, we get 6 with a remainder of 17.
The number 6 becomes the next digit in our result. 
Result so far: 36.0
Subtract 240 from 257 to get 17.
Append the next digit (5) from the dividend to 17 and continue with: 175 / 40

Going ahead to step 5:
175 divided by 40 is 4 with a remainder of 15.
The next digit of our result is 4. 
Result so far: 364.0
Subtracting 160 from 175 leaves us with 15.
Bring next digit (2) of the dividend behind the 15 and repeat the process: 152 / 40

On to step 6:
152 divided by 40 is 3 with a remainder of 32.
Write down 3 as next digit of the result. 
Result so far: 3643.0
If we take 120 away from 152, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 7:
40 can be fit into 320 8 times, resulting in a remainder of 0.
Put 8 as the next digit of the answer. 
Result so far: 3643.8
If we take 320 away from 320, we end up 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 8:
40 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 3643.8
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.

Advancing to step 9:
40 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 3643.8
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.

The quotient of the division is 3643.8, and the remainder is 0.0.
