We're dividing 73143027 by 509 
We want to figure out the number of times 73143027 can be divided by 509.

Going ahead to step 1:
When dividing 7 by 509, we get 0 with 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.
Bring next digit (3) of the dividend behind the 7 and repeat the process: 73 / 509

On to step 2:
If we divide 73 by 509, we get 0 and a remainder of 73.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 73, we end up with 73.
Bring next digit (1) of the dividend behind the 73 and repeat the process: 731 / 509

Advancing to step 3:
If we divide 731 by 509, we get 1 and a remainder of 222.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 509 away from 731, we end up with 222.
Take the next digit (4) from the dividend and append it to 222, then repeat: 2224 / 509

On to step 4:
509 can be fit into 2224 4 times, resulting in a remainder of 188.
The number 4 becomes the next digit in our result. 
Result so far: 14.0
If we take 2036 away from 2224, we end up with 188.
Bring next digit (3) of the dividend behind the 188 and repeat the process: 1883 / 509

On to step 5:
When dividing 1883 by 509, we get 3 with a remainder of 356.
The next digit of our result is 3. 
Result so far: 143.0
If we subtract 1527 from 1883, we get 356.
Include the next digit (0) from the dividend after 356, then repeat: 3560 / 509

Going ahead to step 6:
509 goes into 3560 6 times with a remainder of 506.
The number 6 becomes the next digit in our result. 
Result so far: 1436.0
Subtract 3054 from 3560 to get 506.
Fetch the next digit (2) from the dividend, attach it to 506 and continue: 5062 / 509

Moving on to step 7:
When dividing 5062 by 509, we get 9 with a remainder of 481.
Use 9 as the next digit of our solution. 
Result so far: 14369.0
If we take 4581 away from 5062, we end up with 481.
Fetch the next digit (7) from the dividend, attach it to 481 and continue: 4817 / 509

On to step 8:
If we divide 4817 by 509, we get 9 and a remainder of 236.
Record the quotient 9 as the next digit in the result. 
Result so far: 143699.0
If we subtract 4581 from 4817, we get 236.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2360, and continue the process.

On to step 9:
If we divide 2360 by 509, we get 4 and a remainder of 324.
The next digit of our result is 4. 
Result so far: 143699.4
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.

Step 10:
When dividing 3240 by 509, we get 6 with a remainder of 186.
Use 6 as the next digit of our solution. 
Result so far: 143699.46
Subtracting 3054 from 3240 leaves us with 186.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1860, and continue the process.

On to step 11:
If we divide 1860 by 509, we get 3 and a remainder of 333.
Write down 3 as next digit of the result. 
Result so far: 143699.463
If we take 1527 away from 1860, we end up with 333.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3330, and continue the process.

On to step 12:
When dividing 3330 by 509, we get 6 with a remainder of 276.
Use 6 as the next digit of our solution. 
Result so far: 143699.4636
If we subtract 3054 from 3330, we 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 13:
509 goes into 2760 5 times with a remainder of 215.
Use 5 as the next digit of our solution. 
Result so far: 143699.46365
The remainder is 215 after subtracting 2545 from 2760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2150, and continue the process.

Advancing to step 14:
The number 509 fits into 2150 4 times, leaving a remainder of 114.
Put 4 as the next digit of the answer. 
Result so far: 143699.463654
If we take 2036 away from 2150, we end up with 114.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

On to step 15:
The number 509 fits into 1140 2 times, leaving a remainder of 122.
Use 2 as the next digit of our solution. 
Result so far: 143699.4636542
If we subtract 1018 from 1140, we get 122.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

Going ahead to step 16:
If we divide 1220 by 509, we get 2 and a remainder of 202.
Write down 2 as next digit of the result. 
Result so far: 143699.46365422
If we take 1018 away from 1220, we end up with 202.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2020, and continue the process.

Our division results in 143699.46365422 with a remaining 2.02e-07.
