We're dividing 9580126 by 819 
The aim is to understand the frequency of 819 in 9580126.

Moving on to step 1:
When dividing 9 by 819, we get 0 with a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Bring next digit (5) of the dividend behind the 9 and repeat the process: 95 / 819

Let's proceed to step 2:
819 goes into 95 0 times with a remainder of 95.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 95, we get 95.
Include the next digit (8) from the dividend after 95, then repeat: 958 / 819

On to step 3:
958 divided by 819 is 1 with a remainder of 139.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 139 after subtracting 819 from 958.
Include the next digit (0) from the dividend after 139, then repeat: 1390 / 819

Step 4:
819 goes into 1390 1 times with a remainder of 571.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
Subtract 819 from 1390 to get 571.
Append the next digit (1) from the dividend to 571 and continue with: 5711 / 819

Moving on to step 5:
The number 819 fits into 5711 6 times, leaving a remainder of 797.
The number 6 becomes the next digit in our result. 
Result so far: 116.0
Subtracting 4914 from 5711 leaves us with 797.
Take the next digit (2) from the dividend and append it to 797, then repeat: 7972 / 819

Going ahead to step 6:
819 goes into 7972 9 times with a remainder of 601.
The number 9 becomes the next digit in our result. 
Result so far: 1169.0
If we take 7371 away from 7972, we end up with 601.
Append the next digit (6) from the dividend to 601 and continue with: 6016 / 819

Step 7:
If we divide 6016 by 819, we get 7 and a remainder of 283.
Write down 7 as next digit of the result. 
Result so far: 11697.0
The remainder is 283 after subtracting 5733 from 6016.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2830, and continue the process.

Moving on to step 8:
If we divide 2830 by 819, we get 3 and a remainder of 373.
The next digit of our result is 3. 
Result so far: 11697.3
The remainder is 373 after subtracting 2457 from 2830.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3730, and continue the process.

Going ahead to step 9:
819 can be fit into 3730 4 times, resulting in a remainder of 454.
Put 4 as the next digit of the answer. 
Result so far: 11697.34
Subtracting 3276 from 3730 leaves us with 454.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4540, and continue the process.

Step 10:
819 goes into 4540 5 times with a remainder of 445.
Put 5 as the next digit of the answer. 
Result so far: 11697.345
Deduct 4095 from 4540 and we're left with 445.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4450, and continue the process.

Going ahead to step 11:
The number 819 fits into 4450 5 times, leaving a remainder of 355.
Write down 5 as next digit of the result. 
Result so far: 11697.3455
Subtracting 4095 from 4450 leaves us with 355.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3550, and continue the process.

The final outcome is 11697.3455, with a leftover of 0.00355.
