We look at the division of 73720606 by 509 
Let's see how many times 509 fits into 73720606.

Moving on to step 1:
509 goes into 7 0 times with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Grab the next digit (3) from the dividend, add it to 7, then carry on: 73 / 509

Moving on to step 2:
73 divided by 509 is 0 with a remainder of 73.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 73 to get 73.
Include the next digit (7) from the dividend after 73, then repeat: 737 / 509

Moving on to step 3:
737 divided by 509 is 1 with a remainder of 228.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 509 away from 737, we end up with 228.
Fetch the next digit (2) from the dividend, attach it to 228 and continue: 2282 / 509

Advancing to step 4:
509 goes into 2282 4 times with a remainder of 246.
Record the quotient 4 as the next digit in the result. 
Result so far: 14.0
The remainder is 246 after subtracting 2036 from 2282.
Take the next digit (0) from the dividend and append it to 246, then repeat: 2460 / 509

On to step 5:
The number 509 fits into 2460 4 times, leaving a remainder of 424.
Write down 4 as next digit of the result. 
Result so far: 144.0
If we subtract 2036 from 2460, we get 424.
Append the next digit (6) from the dividend to 424 and continue with: 4246 / 509

Moving on to step 6:
If we divide 4246 by 509, we get 8 and a remainder of 174.
The number 8 becomes the next digit in our result. 
Result so far: 1448.0
If we subtract 4072 from 4246, we get 174.
Bring next digit (0) of the dividend behind the 174 and repeat the process: 1740 / 509

Step 7:
509 can be fit into 1740 3 times, resulting in a remainder of 213.
The number 3 becomes the next digit in our result. 
Result so far: 14483.0
If we subtract 1527 from 1740, we get 213.
Bring next digit (6) of the dividend behind the 213 and repeat the process: 2136 / 509

On to step 8:
If we divide 2136 by 509, we get 4 and a remainder of 100.
Write down 4 as next digit of the result. 
Result so far: 144834.0
Deduct 2036 from 2136 and we're left 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.

Let's proceed to step 9:
509 can be fit into 1000 1 times, resulting in a remainder of 491.
The number 1 becomes the next digit in our result. 
Result so far: 144834.1
Deduct 509 from 1000 and we're left with 491.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4910, and continue the process.

Going ahead to step 10:
4910 divided by 509 is 9 with a remainder of 329.
Write down 9 as next digit of the result. 
Result so far: 144834.19
Subtract 4581 from 4910 to get 329.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3290, and continue the process.

Going ahead to step 11:
509 can be fit into 3290 6 times, resulting in a remainder of 236.
The number 6 becomes the next digit in our result. 
Result so far: 144834.196
Deduct 3054 from 3290 and we're left with 236.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2360, and continue the process.

Advancing to step 12:
2360 divided by 509 is 4 with a remainder of 324.
Put 4 as the next digit of the answer. 
Result so far: 144834.1964
The remainder is 324 after subtracting 2036 from 2360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3240, and continue the process.

Moving on to step 13:
If we divide 3240 by 509, we get 6 and a remainder of 186.
The next digit of our result is 6. 
Result so far: 144834.19646
Subtract 3054 from 3240 to get 186.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1860, and continue the process.

Step 14:
509 can be fit into 1860 3 times, resulting in a remainder of 333.
Put 3 as the next digit of the answer. 
Result so far: 144834.196463
If we subtract 1527 from 1860, we get 333.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3330, and continue the process.

Advancing to step 15:
If we divide 3330 by 509, we get 6 and a remainder of 276.
Put 6 as the next digit of the answer. 
Result so far: 144834.1964636
Subtract 3054 from 3330 to get 276.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2760, and continue the process.

Step 16:
When dividing 2760 by 509, we get 5 with a remainder of 215.
The number 5 becomes the next digit in our result. 
Result so far: 144834.19646365
If we subtract 2545 from 2760, we get 215.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2150, and continue the process.

In conclusion, the division gives 144834.19646365 with a balance of 2.15e-07.
