We're dividing 85312828 by 838 
The aim is to understand the frequency of 838 in 85312828.

Moving on to step 1:
When dividing 8 by 838, we get 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Take the next digit (5) from the dividend and append it to 8, then repeat: 85 / 838

On to step 2:
85 divided by 838 is 0 with a remainder of 85.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 85 and we're left with 85.
Fetch the next digit (3) from the dividend, attach it to 85 and continue: 853 / 838

Moving on to step 3:
When dividing 853 by 838, we get 1 with a remainder of 15.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 838 from 853 and we're left with 15.
Append the next digit (1) from the dividend to 15 and continue with: 151 / 838

Step 4:
151 divided by 838 is 0 with a remainder of 151.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
The remainder is 151 after subtracting 0 from 151.
Include the next digit (2) from the dividend after 151, then repeat: 1512 / 838

Step 5:
The number 838 fits into 1512 1 times, leaving a remainder of 674.
Record the quotient 1 as the next digit in the result. 
Result so far: 101.0
If we take 838 away from 1512, we end up with 674.
Include the next digit (8) from the dividend after 674, then repeat: 6748 / 838

Moving on to step 6:
If we divide 6748 by 838, we get 8 and a remainder of 44.
Use 8 as the next digit of our solution. 
Result so far: 1018.0
The remainder is 44 after subtracting 6704 from 6748.
Grab the next digit (2) from the dividend, add it to 44, then carry on: 442 / 838

On to step 7:
838 can be fit into 442 0 times, resulting in a remainder of 442.
The number 0 becomes the next digit in our result. 
Result so far: 10180.0
If we subtract 0 from 442, we get 442.
Grab the next digit (8) from the dividend, add it to 442, then carry on: 4428 / 838

Advancing to step 8:
When dividing 4428 by 838, we get 5 with a remainder of 238.
The next digit of our result is 5. 
Result so far: 101805.0
If we subtract 4190 from 4428, 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.

Moving on to step 9:
838 goes into 2380 2 times with a remainder of 704.
The number 2 becomes the next digit in our result. 
Result so far: 101805.2
Deduct 1676 from 2380 and we're left with 704.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7040, and continue the process.

Let's proceed to step 10:
838 can be fit into 7040 8 times, resulting in a remainder of 336.
Put 8 as the next digit of the answer. 
Result so far: 101805.28
Subtracting 6704 from 7040 leaves us with 336.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

Going ahead to step 11:
838 goes into 3360 4 times with a remainder of 8.
The next digit of our result is 4. 
Result so far: 101805.284
Subtracting 3352 from 3360 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 12:
838 goes into 80 0 times with a remainder of 80.
Use 0 as the next digit of our solution. 
Result so far: 101805.284
Subtract 0 from 80 to get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Going ahead to step 13:
The number 838 fits into 800 0 times, leaving a remainder of 800.
The number 0 becomes the next digit in our result. 
Result so far: 101805.284
If we subtract 0 from 800, we get 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8000, and continue the process.

After the division, we end up with 101805.284 and a remainder of 0.0008.
