We divide 91146324 by 819
The aim is to understand the frequency of 819 in 91146324.

Step 1:
9 divided by 819 is 0 with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Take the next digit (1) from the dividend and append it to 9, then repeat: 91 / 819

Step 2:
The number 819 fits into 91 0 times, leaving a remainder of 91.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 91 leaves us with 91.
Include the next digit (1) from the dividend after 91, then repeat: 911 / 819

Going ahead to step 3:
If we divide 911 by 819, we get 1 and a remainder of 92.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 819 from 911 and we're left with 92.
Grab the next digit (4) from the dividend, add it to 92, then carry on: 924 / 819

On to step 4:
The number 819 fits into 924 1 times, leaving a remainder of 105.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
If we take 819 away from 924, we end up with 105.
Fetch the next digit (6) from the dividend, attach it to 105 and continue: 1056 / 819

Step 5:
819 can be fit into 1056 1 times, resulting in a remainder of 237.
Put 1 as the next digit of the answer. 
Result so far: 111.0
Subtract 819 from 1056 to get 237.
Append the next digit (3) from the dividend to 237 and continue with: 2373 / 819

Moving on to step 6:
2373 divided by 819 is 2 with a remainder of 735.
Record the quotient 2 as the next digit in the result. 
Result so far: 1112.0
The remainder is 735 after subtracting 1638 from 2373.
Include the next digit (2) from the dividend after 735, then repeat: 7352 / 819

On to step 7:
819 goes into 7352 8 times with a remainder of 800.
Record the quotient 8 as the next digit in the result. 
Result so far: 11128.0
Subtracting 6552 from 7352 leaves us with 800.
Append the next digit (4) from the dividend to 800 and continue with: 8004 / 819

Advancing to step 8:
819 goes into 8004 9 times with a remainder of 633.
The next digit of our result is 9. 
Result so far: 111289.0
Subtracting 7371 from 8004 leaves us with 633.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6330, and continue the process.

Step 9:
819 can be fit into 6330 7 times, resulting in a remainder of 597.
Use 7 as the next digit of our solution. 
Result so far: 111289.7
Subtract 5733 from 6330 to get 597.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5970, and continue the process.

Going ahead to step 10:
5970 divided by 819 is 7 with a remainder of 237.
Use 7 as the next digit of our solution. 
Result so far: 111289.77
The remainder is 237 after subtracting 5733 from 5970.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2370, and continue the process.

The final result is 111289.77 with a remainder of 0.237.
