40007530 ÷ 255 
We want to divide 40007530 by 255.

Advancing to step 1:
When dividing 4 by 255, we get 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Take the next digit (0) from the dividend and append it to 4, then repeat: 40 / 255

Going ahead to step 2:
If we divide 40 by 255, we get 0 and a remainder of 40.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 40, we end up with 40.
Include the next digit (0) from the dividend after 40, then repeat: 400 / 255

Going ahead to step 3:
When dividing 400 by 255, we get 1 with a remainder of 145.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 255 from 400 and we're left with 145.
Include the next digit (0) from the dividend after 145, then repeat: 1450 / 255

Moving on to step 4:
If we divide 1450 by 255, we get 5 and a remainder of 175.
Put 5 as the next digit of the answer. 
Result so far: 15.0
Subtract 1275 from 1450 to get 175.
Take the next digit (7) from the dividend and append it to 175, then repeat: 1757 / 255

Step 5:
1757 divided by 255 is 6 with a remainder of 227.
The number 6 becomes the next digit in our result. 
Result so far: 156.0
If we take 1530 away from 1757, we end up with 227.
Take the next digit (5) from the dividend and append it to 227, then repeat: 2275 / 255

Moving on to step 6:
255 can be fit into 2275 8 times, resulting in a remainder of 235.
Record the quotient 8 as the next digit in the result. 
Result so far: 1568.0
If we subtract 2040 from 2275, we get 235.
Fetch the next digit (3) from the dividend, attach it to 235 and continue: 2353 / 255

Let's proceed to step 7:
If we divide 2353 by 255, we get 9 and a remainder of 58.
Put 9 as the next digit of the answer. 
Result so far: 15689.0
Subtracting 2295 from 2353 leaves us with 58.
Bring next digit (0) of the dividend behind the 58 and repeat the process: 580 / 255

Step 8:
580 divided by 255 is 2 with a remainder of 70.
The next digit of our result is 2. 
Result so far: 156892.0
If we take 510 away from 580, we end up with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Moving on to step 9:
255 goes into 700 2 times with a remainder of 190.
The next digit of our result is 2. 
Result so far: 156892.2
Deduct 510 from 700 and we're left with 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Moving on to step 10:
255 goes into 1900 7 times with a remainder of 115.
The next digit of our result is 7. 
Result so far: 156892.27
Deduct 1785 from 1900 and we're left with 115.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

Going ahead to step 11:
255 goes into 1150 4 times with a remainder of 130.
Put 4 as the next digit of the answer. 
Result so far: 156892.274
Subtracting 1020 from 1150 leaves us with 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Step 12:
When dividing 1300 by 255, we get 5 with a remainder of 25.
The number 5 becomes the next digit in our result. 
Result so far: 156892.2745
If we subtract 1275 from 1300, we get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Step 13:
If we divide 250 by 255, we get 0 and a remainder of 250.
Put 0 as the next digit of the answer. 
Result so far: 156892.2745
The remainder is 250 after subtracting 0 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Step 14:
The number 255 fits into 2500 9 times, leaving a remainder of 205.
The number 9 becomes the next digit in our result. 
Result so far: 156892.274509
Subtract 2295 from 2500 to get 205.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2050, and continue the process.

Step 15:
If we divide 2050 by 255, we get 8 and a remainder of 10.
The next digit of our result is 8. 
Result so far: 156892.2745098
Subtract 2040 from 2050 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 16:
When dividing 100 by 255, we get 0 with a remainder of 100.
The next digit of our result is 0. 
Result so far: 156892.2745098
If we take 0 away from 100, we end up with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

The final result is 156892.2745098 with a remainder of 1e-07.
