We're dividing 28749142 by 465 
The aim is to understand the frequency of 465 in 28749142.

On to step 1:
If we divide 2 by 465, we get 0 and a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Fetch the next digit (8) from the dividend, attach it to 2 and continue: 28 / 465

Advancing to step 2:
465 goes into 28 0 times with a remainder of 28.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 28 and we're left with 28.
Append the next digit (7) from the dividend to 28 and continue with: 287 / 465

On to step 3:
When dividing 287 by 465, we get 0 with a remainder of 287.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 287 leaves us with 287.
Include the next digit (4) from the dividend after 287, then repeat: 2874 / 465

Step 4:
The number 465 fits into 2874 6 times, leaving a remainder of 84.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
Subtracting 2790 from 2874 leaves us with 84.
Bring next digit (9) of the dividend behind the 84 and repeat the process: 849 / 465

Going ahead to step 5:
465 can be fit into 849 1 times, resulting in a remainder of 384.
The number 1 becomes the next digit in our result. 
Result so far: 61.0
If we subtract 465 from 849, we get 384.
Grab the next digit (1) from the dividend, add it to 384, then carry on: 3841 / 465

Advancing to step 6:
3841 divided by 465 is 8 with a remainder of 121.
Record the quotient 8 as the next digit in the result. 
Result so far: 618.0
If we subtract 3720 from 3841, we get 121.
Grab the next digit (4) from the dividend, add it to 121, then carry on: 1214 / 465

Moving on to step 7:
If we divide 1214 by 465, we get 2 and a remainder of 284.
Put 2 as the next digit of the answer. 
Result so far: 6182.0
Subtracting 930 from 1214 leaves us with 284.
Fetch the next digit (2) from the dividend, attach it to 284 and continue: 2842 / 465

On to step 8:
If we divide 2842 by 465, we get 6 and a remainder of 52.
Write down 6 as next digit of the result. 
Result so far: 61826.0
Deduct 2790 from 2842 and we're left with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Let's proceed to step 9:
When dividing 520 by 465, we get 1 with a remainder of 55.
The next digit of our result is 1. 
Result so far: 61826.1
If we subtract 465 from 520, we get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

On to step 10:
465 goes into 550 1 times with a remainder of 85.
Use 1 as the next digit of our solution. 
Result so far: 61826.11
If we take 465 away from 550, we end up with 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

The final result is 61826.11 with a remainder of 0.085.
