We're dividing 81644119 by 509 
We're looking to find how many times 509 goes into 81644119.

On to step 1:
509 can be fit into 8 0 times, resulting in a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Append the next digit (1) from the dividend to 8 and continue with: 81 / 509

On to step 2:
81 divided by 509 is 0 with a remainder of 81.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 81, we get 81.
Include the next digit (6) from the dividend after 81, then repeat: 816 / 509

Advancing to step 3:
509 goes into 816 1 times with a remainder of 307.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 509 from 816 and we're left with 307.
Bring next digit (4) of the dividend behind the 307 and repeat the process: 3074 / 509

Step 4:
509 can be fit into 3074 6 times, resulting in a remainder of 20.
The number 6 becomes the next digit in our result. 
Result so far: 16.0
Subtracting 3054 from 3074 leaves us with 20.
Include the next digit (4) from the dividend after 20, then repeat: 204 / 509

Moving on to step 5:
509 can be fit into 204 0 times, resulting in a remainder of 204.
The number 0 becomes the next digit in our result. 
Result so far: 160.0
Deduct 0 from 204 and we're left with 204.
Append the next digit (1) from the dividend to 204 and continue with: 2041 / 509

Let's proceed to step 6:
If we divide 2041 by 509, we get 4 and a remainder of 5.
Record the quotient 4 as the next digit in the result. 
Result so far: 1604.0
The remainder is 5 after subtracting 2036 from 2041.
Take the next digit (1) from the dividend and append it to 5, then repeat: 51 / 509

Advancing to step 7:
509 goes into 51 0 times with a remainder of 51.
The number 0 becomes the next digit in our result. 
Result so far: 16040.0
The remainder is 51 after subtracting 0 from 51.
Append the next digit (9) from the dividend to 51 and continue with: 519 / 509

On to step 8:
When dividing 519 by 509, we get 1 with a remainder of 10.
Record the quotient 1 as the next digit in the result. 
Result so far: 160401.0
Deduct 509 from 519 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 9:
If we divide 100 by 509, we get 0 and a remainder of 100.
The number 0 becomes the next digit in our result. 
Result so far: 160401.0
If we take 0 away from 100, we end up 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.

Moving on to step 10:
If we divide 1000 by 509, we get 1 and a remainder of 491.
The number 1 becomes the next digit in our result. 
Result so far: 160401.01
If we subtract 509 from 1000, we get 491.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4910, and continue the process.

Moving on to step 11:
509 can be fit into 4910 9 times, resulting in a remainder of 329.
The number 9 becomes the next digit in our result. 
Result so far: 160401.019
If we subtract 4581 from 4910, we 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.

Step 12:
If we divide 3290 by 509, we get 6 and a remainder of 236.
The number 6 becomes the next digit in our result. 
Result so far: 160401.0196
The remainder is 236 after subtracting 3054 from 3290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2360, and continue the process.

Let's proceed to step 13:
2360 divided by 509 is 4 with a remainder of 324.
Write down 4 as next digit of the result. 
Result so far: 160401.01964
Subtracting 2036 from 2360 leaves us with 324.
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 14:
When dividing 3240 by 509, we get 6 with a remainder of 186.
Write down 6 as next digit of the result. 
Result so far: 160401.019646
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.

Moving on to step 15:
509 goes into 1860 3 times with a remainder of 333.
The number 3 becomes the next digit in our result. 
Result so far: 160401.0196463
Subtract 1527 from 1860 to 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.

Going ahead to step 16:
509 can be fit into 3330 6 times, resulting in a remainder of 276.
The next digit of our result is 6. 
Result so far: 160401.01964636
The remainder is 276 after subtracting 3054 from 3330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2760, and continue the process.

After the division, we end up with 160401.01964636 and a remainder of 2.76e-07.
