We look at the division of 7985083 by 805 
The aim is to understand the frequency of 805 in 7985083.

Step 1:
The number 805 fits into 7 0 times, leaving a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Grab the next digit (9) from the dividend, add it to 7, then carry on: 79 / 805

Going ahead to step 2:
79 divided by 805 is 0 with a remainder of 79.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 79, we get 79.
Bring next digit (8) of the dividend behind the 79 and repeat the process: 798 / 805

Moving on to step 3:
805 goes into 798 0 times with a remainder of 798.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 798 leaves us with 798.
Fetch the next digit (5) from the dividend, attach it to 798 and continue: 7985 / 805

Let's proceed to step 4:
The number 805 fits into 7985 9 times, leaving a remainder of 740.
The next digit of our result is 9. 
Result so far: 9.0
Subtract 7245 from 7985 to get 740.
Take the next digit (0) from the dividend and append it to 740, then repeat: 7400 / 805

Advancing to step 5:
7400 divided by 805 is 9 with a remainder of 155.
Put 9 as the next digit of the answer. 
Result so far: 99.0
If we take 7245 away from 7400, we end up with 155.
Append the next digit (8) from the dividend to 155 and continue with: 1558 / 805

Advancing to step 6:
If we divide 1558 by 805, we get 1 and a remainder of 753.
The number 1 becomes the next digit in our result. 
Result so far: 991.0
Subtracting 805 from 1558 leaves us with 753.
Append the next digit (3) from the dividend to 753 and continue with: 7533 / 805

On to step 7:
805 can be fit into 7533 9 times, resulting in a remainder of 288.
The number 9 becomes the next digit in our result. 
Result so far: 9919.0
Subtract 7245 from 7533 to get 288.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

Moving on to step 8:
805 can be fit into 2880 3 times, resulting in a remainder of 465.
The next digit of our result is 3. 
Result so far: 9919.3
Subtract 2415 from 2880 to get 465.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4650, and continue the process.

On to step 9:
If we divide 4650 by 805, we get 5 and a remainder of 625.
Write down 5 as next digit of the result. 
Result so far: 9919.35
The remainder is 625 after subtracting 4025 from 4650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6250, and continue the process.

Moving on to step 10:
If we divide 6250 by 805, we get 7 and a remainder of 615.
The next digit of our result is 7. 
Result so far: 9919.357
The remainder is 615 after subtracting 5635 from 6250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6150, and continue the process.

Going ahead to step 11:
If we divide 6150 by 805, we get 7 and a remainder of 515.
Write down 7 as next digit of the result. 
Result so far: 9919.3577
Deduct 5635 from 6150 and we're left with 515.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5150, and continue the process.

Our division results in 9919.3577 with a remaining 0.00515.
