We're dividing 146469 by 91 
The aim is to understand the frequency of 91 in 146469.

Let's proceed to step 1:
The number 91 fits into 1 0 times, leaving a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Bring next digit (4) of the dividend behind the 1 and repeat the process: 14 / 91

Step 2:
14 divided by 91 is 0 with a remainder of 14.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 14, we get 14.
Append the next digit (6) from the dividend to 14 and continue with: 146 / 91

Let's proceed to step 3:
When dividing 146 by 91, we get 1 with a remainder of 55.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 91 from 146 to get 55.
Grab the next digit (4) from the dividend, add it to 55, then carry on: 554 / 91

Going ahead to step 4:
91 goes into 554 6 times with a remainder of 8.
The next digit of our result is 6. 
Result so far: 16.0
Subtracting 546 from 554 leaves us with 8.
Bring next digit (6) of the dividend behind the 8 and repeat the process: 86 / 91

Let's proceed to step 5:
If we divide 86 by 91, we get 0 and a remainder of 86.
Write down 0 as next digit of the result. 
Result so far: 160.0
Subtract 0 from 86 to get 86.
Append the next digit (9) from the dividend to 86 and continue with: 869 / 91

Going ahead to step 6:
91 goes into 869 9 times with a remainder of 50.
The next digit of our result is 9. 
Result so far: 1609.0
If we take 819 away from 869, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 7:
When dividing 500 by 91, we get 5 with a remainder of 45.
Use 5 as the next digit of our solution. 
Result so far: 1609.5
The remainder is 45 after subtracting 455 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Going ahead to step 8:
If we divide 450 by 91, we get 4 and a remainder of 86.
Record the quotient 4 as the next digit in the result. 
Result so far: 1609.54
Deduct 364 from 450 and we're left with 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Moving on to step 9:
91 can be fit into 860 9 times, resulting in a remainder of 41.
The next digit of our result is 9. 
Result so far: 1609.549
If we subtract 819 from 860, we get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Let's proceed to step 10:
The number 91 fits into 410 4 times, leaving a remainder of 46.
Use 4 as the next digit of our solution. 
Result so far: 1609.5494
Subtract 364 from 410 to get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Let's proceed to step 11:
If we divide 460 by 91, we get 5 and a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 1609.54945
Deduct 455 from 460 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 12:
50 divided by 91 is 0 with a remainder of 50.
Write down 0 as next digit of the result. 
Result so far: 1609.54945
Subtract 0 from 50 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 13:
500 divided by 91 is 5 with a remainder of 45.
Put 5 as the next digit of the answer. 
Result so far: 1609.5494505
Subtracting 455 from 500 leaves us with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Going ahead to step 14:
If we divide 450 by 91, we get 4 and a remainder of 86.
Write down 4 as next digit of the result. 
Result so far: 1609.54945054
Subtracting 364 from 450 leaves us with 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

The final outcome is 1609.54945054, with a leftover of 8.6e-08.
