91341074 ÷ 809 
The aim is to understand the frequency of 809 in 91341074.

On to step 1:
9 divided by 809 is 0 with a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Append the next digit (1) from the dividend to 9 and continue with: 91 / 809

Let's proceed to step 2:
809 goes into 91 0 times with a remainder of 91.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 91 to get 91.
Fetch the next digit (3) from the dividend, attach it to 91 and continue: 913 / 809

Step 3:
913 divided by 809 is 1 with a remainder of 104.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 809 from 913 leaves us with 104.
Append the next digit (4) from the dividend to 104 and continue with: 1044 / 809

Moving on to step 4:
1044 divided by 809 is 1 with a remainder of 235.
The next digit of our result is 1. 
Result so far: 11.0
If we take 809 away from 1044, we end up with 235.
Take the next digit (1) from the dividend and append it to 235, then repeat: 2351 / 809

On to step 5:
The number 809 fits into 2351 2 times, leaving a remainder of 733.
Write down 2 as next digit of the result. 
Result so far: 112.0
The remainder is 733 after subtracting 1618 from 2351.
Fetch the next digit (0) from the dividend, attach it to 733 and continue: 7330 / 809

Advancing to step 6:
If we divide 7330 by 809, we get 9 and a remainder of 49.
Write down 9 as next digit of the result. 
Result so far: 1129.0
If we take 7281 away from 7330, we end up with 49.
Bring next digit (7) of the dividend behind the 49 and repeat the process: 497 / 809

Going ahead to step 7:
809 goes into 497 0 times with a remainder of 497.
Put 0 as the next digit of the answer. 
Result so far: 11290.0
Subtract 0 from 497 to get 497.
Include the next digit (4) from the dividend after 497, then repeat: 4974 / 809

On to step 8:
809 can be fit into 4974 6 times, resulting in a remainder of 120.
Write down 6 as next digit of the result. 
Result so far: 112906.0
The remainder is 120 after subtracting 4854 from 4974.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Going ahead to step 9:
809 can be fit into 1200 1 times, resulting in a remainder of 391.
Write down 1 as next digit of the result. 
Result so far: 112906.1
Deduct 809 from 1200 and we're left with 391.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3910, and continue the process.

On to step 10:
3910 divided by 809 is 4 with a remainder of 674.
Write down 4 as next digit of the result. 
Result so far: 112906.14
Subtracting 3236 from 3910 leaves us with 674.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6740, and continue the process.

Step 11:
6740 divided by 809 is 8 with a remainder of 268.
Put 8 as the next digit of the answer. 
Result so far: 112906.148
The remainder is 268 after subtracting 6472 from 6740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2680, and continue the process.

Moving on to step 12:
809 can be fit into 2680 3 times, resulting in a remainder of 253.
Use 3 as the next digit of our solution. 
Result so far: 112906.1483
The remainder is 253 after subtracting 2427 from 2680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2530, and continue the process.

Advancing to step 13:
The number 809 fits into 2530 3 times, leaving a remainder of 103.
Record the quotient 3 as the next digit in the result. 
Result so far: 112906.14833
The remainder is 103 after subtracting 2427 from 2530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1030, and continue the process.

The final result is 112906.14833 with a remainder of 0.000103.
