We're dividing 34578997 by 239 
The aim is to understand the frequency of 239 in 34578997.

On to step 1:
239 can be fit into 3 0 times, resulting in a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Include the next digit (4) from the dividend after 3, then repeat: 34 / 239

Moving on to step 2:
239 can be fit into 34 0 times, resulting in a remainder of 34.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 34 and we're left with 34.
Take the next digit (5) from the dividend and append it to 34, then repeat: 345 / 239

Step 3:
239 goes into 345 1 times with a remainder of 106.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 239 from 345 leaves us with 106.
Grab the next digit (7) from the dividend, add it to 106, then carry on: 1067 / 239

Step 4:
The number 239 fits into 1067 4 times, leaving a remainder of 111.
The number 4 becomes the next digit in our result. 
Result so far: 14.0
Subtracting 956 from 1067 leaves us with 111.
Include the next digit (8) from the dividend after 111, then repeat: 1118 / 239

Step 5:
239 can be fit into 1118 4 times, resulting in a remainder of 162.
The number 4 becomes the next digit in our result. 
Result so far: 144.0
If we take 956 away from 1118, we end up with 162.
Append the next digit (9) from the dividend to 162 and continue with: 1629 / 239

Step 6:
If we divide 1629 by 239, we get 6 and a remainder of 195.
The next digit of our result is 6. 
Result so far: 1446.0
If we take 1434 away from 1629, we end up with 195.
Bring next digit (9) of the dividend behind the 195 and repeat the process: 1959 / 239

Let's proceed to step 7:
1959 divided by 239 is 8 with a remainder of 47.
The next digit of our result is 8. 
Result so far: 14468.0
If we subtract 1912 from 1959, we get 47.
Take the next digit (7) from the dividend and append it to 47, then repeat: 477 / 239

On to step 8:
477 divided by 239 is 1 with a remainder of 238.
Use 1 as the next digit of our solution. 
Result so far: 144681.0
If we subtract 239 from 477, we get 238.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2380, and continue the process.

Advancing to step 9:
239 can be fit into 2380 9 times, resulting in a remainder of 229.
Put 9 as the next digit of the answer. 
Result so far: 144681.9
If we subtract 2151 from 2380, we get 229.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2290, and continue the process.

Let's proceed to step 10:
If we divide 2290 by 239, we get 9 and a remainder of 139.
Put 9 as the next digit of the answer. 
Result so far: 144681.99
The remainder is 139 after subtracting 2151 from 2290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1390, and continue the process.

The final result is 144681.99 with a remainder of 0.139.
