We're dividing 38561835 by 839 
The aim is to understand the frequency of 839 in 38561835.

Going ahead to step 1:
3 divided by 839 is 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Include the next digit (8) from the dividend after 3, then repeat: 38 / 839

Advancing to step 2:
If we divide 38 by 839, we get 0 and a remainder of 38.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 38 after subtracting 0 from 38.
Fetch the next digit (5) from the dividend, attach it to 38 and continue: 385 / 839

Let's proceed to step 3:
839 goes into 385 0 times with a remainder of 385.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 385 after subtracting 0 from 385.
Take the next digit (6) from the dividend and append it to 385, then repeat: 3856 / 839

On to step 4:
3856 divided by 839 is 4 with a remainder of 500.
Use 4 as the next digit of our solution. 
Result so far: 4.0
If we take 3356 away from 3856, we end up with 500.
Grab the next digit (1) from the dividend, add it to 500, then carry on: 5001 / 839

Going ahead to step 5:
839 goes into 5001 5 times with a remainder of 806.
Use 5 as the next digit of our solution. 
Result so far: 45.0
The remainder is 806 after subtracting 4195 from 5001.
Bring next digit (8) of the dividend behind the 806 and repeat the process: 8068 / 839

Advancing to step 6:
839 goes into 8068 9 times with a remainder of 517.
Put 9 as the next digit of the answer. 
Result so far: 459.0
Subtracting 7551 from 8068 leaves us with 517.
Append the next digit (3) from the dividend to 517 and continue with: 5173 / 839

Moving on to step 7:
839 can be fit into 5173 6 times, resulting in a remainder of 139.
The number 6 becomes the next digit in our result. 
Result so far: 4596.0
The remainder is 139 after subtracting 5034 from 5173.
Bring next digit (5) of the dividend behind the 139 and repeat the process: 1395 / 839

On to step 8:
839 goes into 1395 1 times with a remainder of 556.
Record the quotient 1 as the next digit in the result. 
Result so far: 45961.0
The remainder is 556 after subtracting 839 from 1395.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5560, and continue the process.

On to step 9:
The number 839 fits into 5560 6 times, leaving a remainder of 526.
Use 6 as the next digit of our solution. 
Result so far: 45961.6
Deduct 5034 from 5560 and we're left with 526.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5260, and continue the process.

Moving on to step 10:
If we divide 5260 by 839, we get 6 and a remainder of 226.
Write down 6 as next digit of the result. 
Result so far: 45961.66
If we take 5034 away from 5260, we end up with 226.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2260, and continue the process.

The final result is 45961.66 with a remainder of 0.226.
