We divide 91819411 by 595
The aim is to understand the frequency of 595 in 91819411.

Step 1:
If we divide 9 by 595, we get 0 and a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Include the next digit (1) from the dividend after 9, then repeat: 91 / 595

On to step 2:
The number 595 fits into 91 0 times, leaving a remainder of 91.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 91, we get 91.
Include the next digit (8) from the dividend after 91, then repeat: 918 / 595

Advancing to step 3:
595 goes into 918 1 times with a remainder of 323.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 323 after subtracting 595 from 918.
Append the next digit (1) from the dividend to 323 and continue with: 3231 / 595

Moving on to step 4:
595 can be fit into 3231 5 times, resulting in a remainder of 256.
Put 5 as the next digit of the answer. 
Result so far: 15.0
Deduct 2975 from 3231 and we're left with 256.
Grab the next digit (9) from the dividend, add it to 256, then carry on: 2569 / 595

Going ahead to step 5:
595 goes into 2569 4 times with a remainder of 189.
The next digit of our result is 4. 
Result so far: 154.0
The remainder is 189 after subtracting 2380 from 2569.
Take the next digit (4) from the dividend and append it to 189, then repeat: 1894 / 595

Advancing to step 6:
595 can be fit into 1894 3 times, resulting in a remainder of 109.
The number 3 becomes the next digit in our result. 
Result so far: 1543.0
If we take 1785 away from 1894, we end up with 109.
Append the next digit (1) from the dividend to 109 and continue with: 1091 / 595

Advancing to step 7:
The number 595 fits into 1091 1 times, leaving a remainder of 496.
Record the quotient 1 as the next digit in the result. 
Result so far: 15431.0
If we take 595 away from 1091, we end up with 496.
Fetch the next digit (1) from the dividend, attach it to 496 and continue: 4961 / 595

Let's proceed to step 8:
595 goes into 4961 8 times with a remainder of 201.
Put 8 as the next digit of the answer. 
Result so far: 154318.0
Subtracting 4760 from 4961 leaves us with 201.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2010, and continue the process.

Moving on to step 9:
595 can be fit into 2010 3 times, resulting in a remainder of 225.
The next digit of our result is 3. 
Result so far: 154318.3
The remainder is 225 after subtracting 1785 from 2010.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2250, and continue the process.

Step 10:
When dividing 2250 by 595, we get 3 with a remainder of 465.
Use 3 as the next digit of our solution. 
Result so far: 154318.33
The remainder is 465 after subtracting 1785 from 2250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4650, and continue the process.

The final result is 154318.33 with a remainder of 0.465.
