We look at the division of 13465562 by 905 
The aim is to understand the frequency of 905 in 13465562.

Step 1:
If we divide 1 by 905, we get 0 and a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Take the next digit (3) from the dividend and append it to 1, then repeat: 13 / 905

Step 2:
The number 905 fits into 13 0 times, leaving a remainder of 13.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 13, we get 13.
Grab the next digit (4) from the dividend, add it to 13, then carry on: 134 / 905

On to step 3:
When dividing 134 by 905, we get 0 with a remainder of 134.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 134 after subtracting 0 from 134.
Bring next digit (6) of the dividend behind the 134 and repeat the process: 1346 / 905

Moving on to step 4:
905 can be fit into 1346 1 times, resulting in a remainder of 441.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 905 away from 1346, we end up with 441.
Include the next digit (5) from the dividend after 441, then repeat: 4415 / 905

Moving on to step 5:
4415 divided by 905 is 4 with a remainder of 795.
Record the quotient 4 as the next digit in the result. 
Result so far: 14.0
If we subtract 3620 from 4415, we get 795.
Include the next digit (5) from the dividend after 795, then repeat: 7955 / 905

Advancing to step 6:
905 can be fit into 7955 8 times, resulting in a remainder of 715.
The number 8 becomes the next digit in our result. 
Result so far: 148.0
If we take 7240 away from 7955, we end up with 715.
Take the next digit (6) from the dividend and append it to 715, then repeat: 7156 / 905

Going ahead to step 7:
The number 905 fits into 7156 7 times, leaving a remainder of 821.
The number 7 becomes the next digit in our result. 
Result so far: 1487.0
If we take 6335 away from 7156, we end up with 821.
Append the next digit (2) from the dividend to 821 and continue with: 8212 / 905

Moving on to step 8:
If we divide 8212 by 905, we get 9 and a remainder of 67.
Use 9 as the next digit of our solution. 
Result so far: 14879.0
Subtracting 8145 from 8212 leaves us with 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Step 9:
If we divide 670 by 905, we get 0 and a remainder of 670.
The number 0 becomes the next digit in our result. 
Result so far: 14879.0
Subtracting 0 from 670 leaves us with 670.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6700, and continue the process.

Moving on to step 10:
905 can be fit into 6700 7 times, resulting in a remainder of 365.
Put 7 as the next digit of the answer. 
Result so far: 14879.07
Deduct 6335 from 6700 and we're left with 365.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3650, and continue the process.

Advancing to step 11:
3650 divided by 905 is 4 with a remainder of 30.
Write down 4 as next digit of the result. 
Result so far: 14879.074
Subtracting 3620 from 3650 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 12:
300 divided by 905 is 0 with a remainder of 300.
The number 0 becomes the next digit in our result. 
Result so far: 14879.074
Deduct 0 from 300 and we're left with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Step 13:
3000 divided by 905 is 3 with a remainder of 285.
Put 3 as the next digit of the answer. 
Result so far: 14879.07403
Deduct 2715 from 3000 and we're left with 285.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2850, and continue the process.

Let's proceed to step 14:
When dividing 2850 by 905, we get 3 with a remainder of 135.
Use 3 as the next digit of our solution. 
Result so far: 14879.074033
Deduct 2715 from 2850 and we're left with 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

The final result is 14879.074033 with a remainder of 1.35e-05.
