We look at the division of 91711134 by 415 
The aim is to understand the frequency of 415 in 91711134.

Advancing to step 1:
415 can be fit into 9 0 times, resulting in a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Fetch the next digit (1) from the dividend, attach it to 9 and continue: 91 / 415

On to step 2:
The number 415 fits into 91 0 times, leaving a remainder of 91.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 91, we get 91.
Fetch the next digit (7) from the dividend, attach it to 91 and continue: 917 / 415

Step 3:
When dividing 917 by 415, we get 2 with a remainder of 87.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we subtract 830 from 917, we get 87.
Include the next digit (1) from the dividend after 87, then repeat: 871 / 415

Going ahead to step 4:
871 divided by 415 is 2 with a remainder of 41.
The number 2 becomes the next digit in our result. 
Result so far: 22.0
The remainder is 41 after subtracting 830 from 871.
Take the next digit (1) from the dividend and append it to 41, then repeat: 411 / 415

On to step 5:
415 goes into 411 0 times with a remainder of 411.
Use 0 as the next digit of our solution. 
Result so far: 220.0
The remainder is 411 after subtracting 0 from 411.
Include the next digit (1) from the dividend after 411, then repeat: 4111 / 415

Let's proceed to step 6:
415 can be fit into 4111 9 times, resulting in a remainder of 376.
Write down 9 as next digit of the result. 
Result so far: 2209.0
Deduct 3735 from 4111 and we're left with 376.
Bring next digit (3) of the dividend behind the 376 and repeat the process: 3763 / 415

Going ahead to step 7:
The number 415 fits into 3763 9 times, leaving a remainder of 28.
Use 9 as the next digit of our solution. 
Result so far: 22099.0
If we take 3735 away from 3763, we end up with 28.
Take the next digit (4) from the dividend and append it to 28, then repeat: 284 / 415

Step 8:
415 can be fit into 284 0 times, resulting in a remainder of 284.
Record the quotient 0 as the next digit in the result. 
Result so far: 220990.0
Subtracting 0 from 284 leaves us with 284.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2840, and continue the process.

Moving on to step 9:
When dividing 2840 by 415, we get 6 with a remainder of 350.
Put 6 as the next digit of the answer. 
Result so far: 220990.6
Deduct 2490 from 2840 and we're left with 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

On to step 10:
If we divide 3500 by 415, we get 8 and a remainder of 180.
The next digit of our result is 8. 
Result so far: 220990.68
The remainder is 180 after subtracting 3320 from 3500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Going ahead to step 11:
1800 divided by 415 is 4 with a remainder of 140.
Use 4 as the next digit of our solution. 
Result so far: 220990.684
If we subtract 1660 from 1800, we get 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Moving on to step 12:
When dividing 1400 by 415, we get 3 with a remainder of 155.
Use 3 as the next digit of our solution. 
Result so far: 220990.6843
Deduct 1245 from 1400 and we're left with 155.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1550, and continue the process.

Let's proceed to step 13:
415 can be fit into 1550 3 times, resulting in a remainder of 305.
The number 3 becomes the next digit in our result. 
Result so far: 220990.68433
Subtract 1245 from 1550 to get 305.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3050, and continue the process.

The quotient of the division is 220990.68433, and the remainder is 0.000305.
