We divide 75505813 by 509
We want to divide 75505813 by 509.

Step 1:
509 goes into 7 0 times with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Fetch the next digit (5) from the dividend, attach it to 7 and continue: 75 / 509

Going ahead to step 2:
If we divide 75 by 509, we get 0 and a remainder of 75.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 75 to get 75.
Bring next digit (5) of the dividend behind the 75 and repeat the process: 755 / 509

Moving on to step 3:
755 divided by 509 is 1 with a remainder of 246.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 509 away from 755, we end up with 246.
Include the next digit (0) from the dividend after 246, then repeat: 2460 / 509

Advancing to step 4:
The number 509 fits into 2460 4 times, leaving a remainder of 424.
The next digit of our result is 4. 
Result so far: 14.0
If we subtract 2036 from 2460, we get 424.
Bring next digit (5) of the dividend behind the 424 and repeat the process: 4245 / 509

Let's proceed to step 5:
509 can be fit into 4245 8 times, resulting in a remainder of 173.
The number 8 becomes the next digit in our result. 
Result so far: 148.0
If we take 4072 away from 4245, we end up with 173.
Grab the next digit (8) from the dividend, add it to 173, then carry on: 1738 / 509

Moving on to step 6:
1738 divided by 509 is 3 with a remainder of 211.
The number 3 becomes the next digit in our result. 
Result so far: 1483.0
Subtract 1527 from 1738 to get 211.
Fetch the next digit (1) from the dividend, attach it to 211 and continue: 2111 / 509

Going ahead to step 7:
509 goes into 2111 4 times with a remainder of 75.
Use 4 as the next digit of our solution. 
Result so far: 14834.0
Deduct 2036 from 2111 and we're left with 75.
Append the next digit (3) from the dividend to 75 and continue with: 753 / 509

Going ahead to step 8:
753 divided by 509 is 1 with a remainder of 244.
Put 1 as the next digit of the answer. 
Result so far: 148341.0
If we take 509 away from 753, we end up with 244.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2440, and continue the process.

Step 9:
The number 509 fits into 2440 4 times, leaving a remainder of 404.
Record the quotient 4 as the next digit in the result. 
Result so far: 148341.4
Deduct 2036 from 2440 and we're left with 404.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4040, and continue the process.

On to step 10:
If we divide 4040 by 509, we get 7 and a remainder of 477.
Record the quotient 7 as the next digit in the result. 
Result so far: 148341.47
If we take 3563 away from 4040, we end up with 477.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4770, and continue the process.

Moving on to step 11:
4770 divided by 509 is 9 with a remainder of 189.
Record the quotient 9 as the next digit in the result. 
Result so far: 148341.479
If we subtract 4581 from 4770, we get 189.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1890, and continue the process.

On to step 12:
1890 divided by 509 is 3 with a remainder of 363.
Write down 3 as next digit of the result. 
Result so far: 148341.4793
Subtract 1527 from 1890 to get 363.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3630, and continue the process.

On to step 13:
The number 509 fits into 3630 7 times, leaving a remainder of 67.
The next digit of our result is 7. 
Result so far: 148341.47937
Deduct 3563 from 3630 and we're left with 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Advancing to step 14:
When dividing 670 by 509, we get 1 with a remainder of 161.
Use 1 as the next digit of our solution. 
Result so far: 148341.479371
Deduct 509 from 670 and we're left with 161.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1610, and continue the process.

Step 15:
509 goes into 1610 3 times with a remainder of 83.
The next digit of our result is 3. 
Result so far: 148341.4793713
If we take 1527 away from 1610, we end up with 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

Step 16:
The number 509 fits into 830 1 times, leaving a remainder of 321.
The next digit of our result is 1. 
Result so far: 148341.47937131
Deduct 509 from 830 and we're left with 321.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3210, and continue the process.

In conclusion, the division gives 148341.47937131 with a balance of 3.21e-07.
