We're dividing 45231235 by 913 
The aim is to understand the frequency of 913 in 45231235.

Moving on to step 1:
913 can be fit into 4 0 times, resulting in a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Fetch the next digit (5) from the dividend, attach it to 4 and continue: 45 / 913

Advancing to step 2:
If we divide 45 by 913, we get 0 and a remainder of 45.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 45 and we're left with 45.
Bring next digit (2) of the dividend behind the 45 and repeat the process: 452 / 913

On to step 3:
913 goes into 452 0 times with a remainder of 452.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 452 to get 452.
Bring next digit (3) of the dividend behind the 452 and repeat the process: 4523 / 913

Advancing to step 4:
If we divide 4523 by 913, we get 4 and a remainder of 871.
The next digit of our result is 4. 
Result so far: 4.0
Subtract 3652 from 4523 to get 871.
Take the next digit (1) from the dividend and append it to 871, then repeat: 8711 / 913

Let's proceed to step 5:
The number 913 fits into 8711 9 times, leaving a remainder of 494.
Write down 9 as next digit of the result. 
Result so far: 49.0
If we subtract 8217 from 8711, we get 494.
Bring next digit (2) of the dividend behind the 494 and repeat the process: 4942 / 913

Let's proceed to step 6:
913 can be fit into 4942 5 times, resulting in a remainder of 377.
Record the quotient 5 as the next digit in the result. 
Result so far: 495.0
The remainder is 377 after subtracting 4565 from 4942.
Include the next digit (3) from the dividend after 377, then repeat: 3773 / 913

Let's proceed to step 7:
When dividing 3773 by 913, we get 4 with a remainder of 121.
Record the quotient 4 as the next digit in the result. 
Result so far: 4954.0
The remainder is 121 after subtracting 3652 from 3773.
Grab the next digit (5) from the dividend, add it to 121, then carry on: 1215 / 913

Step 8:
913 goes into 1215 1 times with a remainder of 302.
Put 1 as the next digit of the answer. 
Result so far: 49541.0
If we take 913 away from 1215, we end up with 302.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3020, and continue the process.

On to step 9:
The number 913 fits into 3020 3 times, leaving a remainder of 281.
The next digit of our result is 3. 
Result so far: 49541.3
Subtracting 2739 from 3020 leaves us with 281.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2810, and continue the process.

Moving on to step 10:
When dividing 2810 by 913, we get 3 with a remainder of 71.
Use 3 as the next digit of our solution. 
Result so far: 49541.33
Subtract 2739 from 2810 to get 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

After the division, we end up with 49541.33 and a remainder of 0.071.
