We're dividing 83717509 by 239 
The aim is to understand the frequency of 239 in 83717509.

Going ahead to step 1:
The number 239 fits into 8 0 times, leaving a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Take the next digit (3) from the dividend and append it to 8, then repeat: 83 / 239

Advancing to step 2:
239 can be fit into 83 0 times, resulting in a remainder of 83.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 83, we get 83.
Grab the next digit (7) from the dividend, add it to 83, then carry on: 837 / 239

On to step 3:
The number 239 fits into 837 3 times, leaving a remainder of 120.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we take 717 away from 837, we end up with 120.
Bring next digit (1) of the dividend behind the 120 and repeat the process: 1201 / 239

Going ahead to step 4:
If we divide 1201 by 239, we get 5 and a remainder of 6.
Record the quotient 5 as the next digit in the result. 
Result so far: 35.0
If we take 1195 away from 1201, we end up with 6.
Append the next digit (7) from the dividend to 6 and continue with: 67 / 239

Let's proceed to step 5:
When dividing 67 by 239, we get 0 with a remainder of 67.
Use 0 as the next digit of our solution. 
Result so far: 350.0
If we take 0 away from 67, we end up with 67.
Append the next digit (5) from the dividend to 67 and continue with: 675 / 239

Going ahead to step 6:
239 goes into 675 2 times with a remainder of 197.
Write down 2 as next digit of the result. 
Result so far: 3502.0
If we take 478 away from 675, we end up with 197.
Grab the next digit (0) from the dividend, add it to 197, then carry on: 1970 / 239

Advancing to step 7:
If we divide 1970 by 239, we get 8 and a remainder of 58.
The number 8 becomes the next digit in our result. 
Result so far: 35028.0
If we take 1912 away from 1970, we end up with 58.
Grab the next digit (9) from the dividend, add it to 58, then carry on: 589 / 239

Step 8:
If we divide 589 by 239, we get 2 and a remainder of 111.
Use 2 as the next digit of our solution. 
Result so far: 350282.0
If we take 478 away from 589, we end up with 111.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1110, and continue the process.

Advancing to step 9:
If we divide 1110 by 239, we get 4 and a remainder of 154.
Put 4 as the next digit of the answer. 
Result so far: 350282.4
If we subtract 956 from 1110, we get 154.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1540, and continue the process.

Moving on to step 10:
239 goes into 1540 6 times with a remainder of 106.
Put 6 as the next digit of the answer. 
Result so far: 350282.46
Subtract 1434 from 1540 to get 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

Moving on to step 11:
If we divide 1060 by 239, we get 4 and a remainder of 104.
Use 4 as the next digit of our solution. 
Result so far: 350282.464
If we take 956 away from 1060, we end up with 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Going ahead to step 12:
239 goes into 1040 4 times with a remainder of 84.
Record the quotient 4 as the next digit in the result. 
Result so far: 350282.4644
Subtracting 956 from 1040 leaves us with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

The final result is 350282.4644 with a remainder of 0.00084.
