We look at the division of 74405909 by 531 
Our goal is to divide 74405909 by 531.

Step 1:
531 can be fit into 7 0 times, resulting in a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Append the next digit (4) from the dividend to 7 and continue with: 74 / 531

Going ahead to step 2:
If we divide 74 by 531, we get 0 and a remainder of 74.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 74 leaves us with 74.
Take the next digit (4) from the dividend and append it to 74, then repeat: 744 / 531

Moving on to step 3:
If we divide 744 by 531, we get 1 and a remainder of 213.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 531 away from 744, we end up with 213.
Append the next digit (0) from the dividend to 213 and continue with: 2130 / 531

Moving on to step 4:
531 goes into 2130 4 times with a remainder of 6.
The next digit of our result is 4. 
Result so far: 14.0
The remainder is 6 after subtracting 2124 from 2130.
Fetch the next digit (5) from the dividend, attach it to 6 and continue: 65 / 531

Going ahead to step 5:
When dividing 65 by 531, we get 0 with a remainder of 65.
Record the quotient 0 as the next digit in the result. 
Result so far: 140.0
If we take 0 away from 65, we end up with 65.
Include the next digit (9) from the dividend after 65, then repeat: 659 / 531

Step 6:
The number 531 fits into 659 1 times, leaving a remainder of 128.
Put 1 as the next digit of the answer. 
Result so far: 1401.0
If we subtract 531 from 659, we get 128.
Include the next digit (0) from the dividend after 128, then repeat: 1280 / 531

On to step 7:
531 goes into 1280 2 times with a remainder of 218.
The next digit of our result is 2. 
Result so far: 14012.0
Subtracting 1062 from 1280 leaves us with 218.
Append the next digit (9) from the dividend to 218 and continue with: 2189 / 531

Going ahead to step 8:
531 can be fit into 2189 4 times, resulting in a remainder of 65.
Write down 4 as next digit of the result. 
Result so far: 140124.0
Deduct 2124 from 2189 and we're left with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Going ahead to step 9:
531 goes into 650 1 times with a remainder of 119.
The number 1 becomes the next digit in our result. 
Result so far: 140124.1
The remainder is 119 after subtracting 531 from 650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1190, and continue the process.

Moving on to step 10:
1190 divided by 531 is 2 with a remainder of 128.
Write down 2 as next digit of the result. 
Result so far: 140124.12
If we subtract 1062 from 1190, we get 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Going ahead to step 11:
1280 divided by 531 is 2 with a remainder of 218.
Record the quotient 2 as the next digit in the result. 
Result so far: 140124.122
Subtracting 1062 from 1280 leaves us with 218.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2180, and continue the process.

The quotient of the division is 140124.122, and the remainder is 0.0218.
