We look at the division of 85192786 by 820 
The aim is to understand the frequency of 820 in 85192786.

Advancing to step 1:
820 can be fit into 8 0 times, resulting in a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Append the next digit (5) from the dividend to 8 and continue with: 85 / 820

Let's proceed to step 2:
820 can be fit into 85 0 times, resulting in a remainder of 85.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 85 to get 85.
Bring next digit (1) of the dividend behind the 85 and repeat the process: 851 / 820

Going ahead to step 3:
820 can be fit into 851 1 times, resulting in a remainder of 31.
The next digit of our result is 1. 
Result so far: 1.0
If we take 820 away from 851, we end up with 31.
Fetch the next digit (9) from the dividend, attach it to 31 and continue: 319 / 820

Advancing to step 4:
820 goes into 319 0 times with a remainder of 319.
Use 0 as the next digit of our solution. 
Result so far: 10.0
If we subtract 0 from 319, we get 319.
Bring next digit (2) of the dividend behind the 319 and repeat the process: 3192 / 820

On to step 5:
820 goes into 3192 3 times with a remainder of 732.
Put 3 as the next digit of the answer. 
Result so far: 103.0
Subtracting 2460 from 3192 leaves us with 732.
Grab the next digit (7) from the dividend, add it to 732, then carry on: 7327 / 820

On to step 6:
7327 divided by 820 is 8 with a remainder of 767.
Write down 8 as next digit of the result. 
Result so far: 1038.0
Subtracting 6560 from 7327 leaves us with 767.
Grab the next digit (8) from the dividend, add it to 767, then carry on: 7678 / 820

Advancing to step 7:
If we divide 7678 by 820, we get 9 and a remainder of 298.
Record the quotient 9 as the next digit in the result. 
Result so far: 10389.0
Subtract 7380 from 7678 to get 298.
Append the next digit (6) from the dividend to 298 and continue with: 2986 / 820

Going ahead to step 8:
When dividing 2986 by 820, we get 3 with a remainder of 526.
Record the quotient 3 as the next digit in the result. 
Result so far: 103893.0
Subtracting 2460 from 2986 leaves us 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.

Let's proceed to step 9:
820 goes into 5260 6 times with a remainder of 340.
Write down 6 as next digit of the result. 
Result so far: 103893.6
The remainder is 340 after subtracting 4920 from 5260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Going ahead to step 10:
If we divide 3400 by 820, we get 4 and a remainder of 120.
Write down 4 as next digit of the result. 
Result so far: 103893.64
Deduct 3280 from 3400 and we're left with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

On to step 11:
820 goes into 1200 1 times with a remainder of 380.
Use 1 as the next digit of our solution. 
Result so far: 103893.641
Deduct 820 from 1200 and we're left with 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Moving on to step 12:
3800 divided by 820 is 4 with a remainder of 520.
Put 4 as the next digit of the answer. 
Result so far: 103893.6414
Subtracting 3280 from 3800 leaves us with 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

Advancing to step 13:
If we divide 5200 by 820, we get 6 and a remainder of 280.
Use 6 as the next digit of our solution. 
Result so far: 103893.64146
Subtract 4920 from 5200 to get 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

On to step 14:
2800 divided by 820 is 3 with a remainder of 340.
The next digit of our result is 3. 
Result so far: 103893.641463
If we subtract 2460 from 2800, we get 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Going ahead to step 15:
The number 820 fits into 3400 4 times, leaving a remainder of 120.
The next digit of our result is 4. 
Result so far: 103893.6414634
If we take 3280 away from 3400, we end up with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Step 16:
The number 820 fits into 1200 1 times, leaving a remainder of 380.
Put 1 as the next digit of the answer. 
Result so far: 103893.64146341
The remainder is 380 after subtracting 820 from 1200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

The final result is 103893.64146341 with a remainder of 3.8e-07.
