We look at the division of 74910416 by 509 
We're looking to find how many times 509 goes into 74910416.

On to step 1:
The number 509 fits into 7 0 times, leaving a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Bring next digit (4) of the dividend behind the 7 and repeat the process: 74 / 509

Step 2:
If we divide 74 by 509, we get 0 and a remainder of 74.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 74 and we're left with 74.
Bring next digit (9) of the dividend behind the 74 and repeat the process: 749 / 509

On to step 3:
509 can be fit into 749 1 times, resulting in a remainder of 240.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 509 from 749, we get 240.
Take the next digit (1) from the dividend and append it to 240, then repeat: 2401 / 509

Let's proceed to step 4:
509 can be fit into 2401 4 times, resulting in a remainder of 365.
The next digit of our result is 4. 
Result so far: 14.0
If we take 2036 away from 2401, we end up with 365.
Fetch the next digit (0) from the dividend, attach it to 365 and continue: 3650 / 509

Going ahead to step 5:
509 goes into 3650 7 times with a remainder of 87.
The next digit of our result is 7. 
Result so far: 147.0
If we subtract 3563 from 3650, we get 87.
Append the next digit (4) from the dividend to 87 and continue with: 874 / 509

Going ahead to step 6:
509 can be fit into 874 1 times, resulting in a remainder of 365.
Write down 1 as next digit of the result. 
Result so far: 1471.0
Deduct 509 from 874 and we're left with 365.
Append the next digit (1) from the dividend to 365 and continue with: 3651 / 509

On to step 7:
If we divide 3651 by 509, we get 7 and a remainder of 88.
Put 7 as the next digit of the answer. 
Result so far: 14717.0
Subtract 3563 from 3651 to get 88.
Grab the next digit (6) from the dividend, add it to 88, then carry on: 886 / 509

Going ahead to step 8:
If we divide 886 by 509, we get 1 and a remainder of 377.
Record the quotient 1 as the next digit in the result. 
Result so far: 147171.0
The remainder is 377 after subtracting 509 from 886.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3770, and continue the process.

Moving on to step 9:
When dividing 3770 by 509, we get 7 with a remainder of 207.
Write down 7 as next digit of the result. 
Result so far: 147171.7
If we take 3563 away from 3770, we end up with 207.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2070, and continue the process.

On to step 10:
509 can be fit into 2070 4 times, resulting in a remainder of 34.
Write down 4 as next digit of the result. 
Result so far: 147171.74
Subtracting 2036 from 2070 leaves us with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

On to step 11:
If we divide 340 by 509, we get 0 and a remainder of 340.
The number 0 becomes the next digit in our result. 
Result so far: 147171.74
If we subtract 0 from 340, we get 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Moving on to step 12:
509 goes into 3400 6 times with a remainder of 346.
Record the quotient 6 as the next digit in the result. 
Result so far: 147171.7406
Subtracting 3054 from 3400 leaves us with 346.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3460, and continue the process.

Advancing to step 13:
509 can be fit into 3460 6 times, resulting in a remainder of 406.
Use 6 as the next digit of our solution. 
Result so far: 147171.74066
If we subtract 3054 from 3460, we get 406.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4060, and continue the process.

Our division results in 147171.74066 with a remaining 0.000406.
