We divide 73407087 by 509
Our goal is to divide 73407087 by 509.

On to step 1:
509 can be fit into 7 0 times, resulting in a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Fetch the next digit (3) from the dividend, attach it to 7 and continue: 73 / 509

Let's proceed to step 2:
If we divide 73 by 509, we get 0 and a remainder of 73.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 73 after subtracting 0 from 73.
Grab the next digit (4) from the dividend, add it to 73, then carry on: 734 / 509

Advancing to step 3:
When dividing 734 by 509, we get 1 with a remainder of 225.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 509 from 734 leaves us with 225.
Take the next digit (0) from the dividend and append it to 225, then repeat: 2250 / 509

Let's proceed to step 4:
The number 509 fits into 2250 4 times, leaving a remainder of 214.
Put 4 as the next digit of the answer. 
Result so far: 14.0
Subtracting 2036 from 2250 leaves us with 214.
Bring next digit (7) of the dividend behind the 214 and repeat the process: 2147 / 509

On to step 5:
509 can be fit into 2147 4 times, resulting in a remainder of 111.
Write down 4 as next digit of the result. 
Result so far: 144.0
Subtracting 2036 from 2147 leaves us with 111.
Bring next digit (0) of the dividend behind the 111 and repeat the process: 1110 / 509

Going ahead to step 6:
1110 divided by 509 is 2 with a remainder of 92.
Write down 2 as next digit of the result. 
Result so far: 1442.0
Deduct 1018 from 1110 and we're left with 92.
Bring next digit (8) of the dividend behind the 92 and repeat the process: 928 / 509

Advancing to step 7:
When dividing 928 by 509, we get 1 with a remainder of 419.
Put 1 as the next digit of the answer. 
Result so far: 14421.0
Subtracting 509 from 928 leaves us with 419.
Include the next digit (7) from the dividend after 419, then repeat: 4197 / 509

Step 8:
509 goes into 4197 8 times with a remainder of 125.
Put 8 as the next digit of the answer. 
Result so far: 144218.0
Subtract 4072 from 4197 to get 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

Advancing to step 9:
509 goes into 1250 2 times with a remainder of 232.
Write down 2 as next digit of the result. 
Result so far: 144218.2
Subtract 1018 from 1250 to get 232.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2320, and continue the process.

On to step 10:
509 goes into 2320 4 times with a remainder of 284.
Write down 4 as next digit of the result. 
Result so far: 144218.24
Deduct 2036 from 2320 and we're left with 284.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2840, and continue the process.

Moving on to step 11:
When dividing 2840 by 509, we get 5 with a remainder of 295.
The next digit of our result is 5. 
Result so far: 144218.245
If we take 2545 away from 2840, we end up with 295.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2950, and continue the process.

On to step 12:
509 goes into 2950 5 times with a remainder of 405.
Use 5 as the next digit of our solution. 
Result so far: 144218.2455
The remainder is 405 after subtracting 2545 from 2950.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4050, and continue the process.

The final outcome is 144218.2455, with a leftover of 0.00405.
