We divide 83440525 by 509
The aim is to understand the frequency of 509 in 83440525.

Moving on to step 1:
509 goes into 8 0 times with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Grab the next digit (3) from the dividend, add it to 8, then carry on: 83 / 509

On to step 2:
The number 509 fits into 83 0 times, leaving a remainder of 83.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 83 after subtracting 0 from 83.
Append the next digit (4) from the dividend to 83 and continue with: 834 / 509

Advancing to step 3:
The number 509 fits into 834 1 times, leaving a remainder of 325.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 509 from 834 leaves us with 325.
Bring next digit (4) of the dividend behind the 325 and repeat the process: 3254 / 509

Moving on to step 4:
509 goes into 3254 6 times with a remainder of 200.
The next digit of our result is 6. 
Result so far: 16.0
Subtracting 3054 from 3254 leaves us with 200.
Fetch the next digit (0) from the dividend, attach it to 200 and continue: 2000 / 509

On to step 5:
If we divide 2000 by 509, we get 3 and a remainder of 473.
The number 3 becomes the next digit in our result. 
Result so far: 163.0
Subtract 1527 from 2000 to get 473.
Grab the next digit (5) from the dividend, add it to 473, then carry on: 4735 / 509

Going ahead to step 6:
4735 divided by 509 is 9 with a remainder of 154.
Record the quotient 9 as the next digit in the result. 
Result so far: 1639.0
If we subtract 4581 from 4735, we get 154.
Bring next digit (2) of the dividend behind the 154 and repeat the process: 1542 / 509

Moving on to step 7:
If we divide 1542 by 509, we get 3 and a remainder of 15.
Put 3 as the next digit of the answer. 
Result so far: 16393.0
The remainder is 15 after subtracting 1527 from 1542.
Append the next digit (5) from the dividend to 15 and continue with: 155 / 509

Moving on to step 8:
155 divided by 509 is 0 with a remainder of 155.
The number 0 becomes the next digit in our result. 
Result so far: 163930.0
Subtract 0 from 155 to get 155.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1550, and continue the process.

Let's proceed to step 9:
When dividing 1550 by 509, we get 3 with a remainder of 23.
The next digit of our result is 3. 
Result so far: 163930.3
Subtract 1527 from 1550 to get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

On to step 10:
If we divide 230 by 509, we get 0 and a remainder of 230.
Use 0 as the next digit of our solution. 
Result so far: 163930.3
If we subtract 0 from 230, we get 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

On to step 11:
2300 divided by 509 is 4 with a remainder of 264.
Put 4 as the next digit of the answer. 
Result so far: 163930.304
Subtract 2036 from 2300 to get 264.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2640, and continue the process.

On to step 12:
509 goes into 2640 5 times with a remainder of 95.
Write down 5 as next digit of the result. 
Result so far: 163930.3045
The remainder is 95 after subtracting 2545 from 2640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

Step 13:
The number 509 fits into 950 1 times, leaving a remainder of 441.
The number 1 becomes the next digit in our result. 
Result so far: 163930.30451
If we take 509 away from 950, we end up with 441.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4410, and continue the process.

Step 14:
4410 divided by 509 is 8 with a remainder of 338.
Use 8 as the next digit of our solution. 
Result so far: 163930.304518
If we subtract 4072 from 4410, we get 338.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3380, and continue the process.

Let's proceed to step 15:
The number 509 fits into 3380 6 times, leaving a remainder of 326.
Write down 6 as next digit of the result. 
Result so far: 163930.3045186
If we subtract 3054 from 3380, we get 326.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3260, and continue the process.

Step 16:
When dividing 3260 by 509, we get 6 with a remainder of 206.
The next digit of our result is 6. 
Result so far: 163930.30451866
If we take 3054 away from 3260, we end up with 206.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2060, and continue the process.

The quotient of the division is 163930.30451866, and the remainder is 2.06e-07.
