90142828 ÷ 465 
The aim is to understand the frequency of 465 in 90142828.

Going ahead to step 1:
If we divide 9 by 465, we get 0 and a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Append the next digit (0) from the dividend to 9 and continue with: 90 / 465

Step 2:
465 can be fit into 90 0 times, resulting in a remainder of 90.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 90 to get 90.
Append the next digit (1) from the dividend to 90 and continue with: 901 / 465

On to step 3:
The number 465 fits into 901 1 times, leaving a remainder of 436.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 465 from 901 to get 436.
Take the next digit (4) from the dividend and append it to 436, then repeat: 4364 / 465

Moving on to step 4:
465 goes into 4364 9 times with a remainder of 179.
The next digit of our result is 9. 
Result so far: 19.0
Subtracting 4185 from 4364 leaves us with 179.
Append the next digit (2) from the dividend to 179 and continue with: 1792 / 465

Let's proceed to step 5:
465 can be fit into 1792 3 times, resulting in a remainder of 397.
Use 3 as the next digit of our solution. 
Result so far: 193.0
Subtracting 1395 from 1792 leaves us with 397.
Append the next digit (8) from the dividend to 397 and continue with: 3978 / 465

Going ahead to step 6:
When dividing 3978 by 465, we get 8 with a remainder of 258.
Put 8 as the next digit of the answer. 
Result so far: 1938.0
Deduct 3720 from 3978 and we're left with 258.
Take the next digit (2) from the dividend and append it to 258, then repeat: 2582 / 465

Advancing to step 7:
When dividing 2582 by 465, we get 5 with a remainder of 257.
Record the quotient 5 as the next digit in the result. 
Result so far: 19385.0
The remainder is 257 after subtracting 2325 from 2582.
Grab the next digit (8) from the dividend, add it to 257, then carry on: 2578 / 465

Step 8:
2578 divided by 465 is 5 with a remainder of 253.
Write down 5 as next digit of the result. 
Result so far: 193855.0
The remainder is 253 after subtracting 2325 from 2578.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2530, and continue the process.

Advancing to step 9:
465 can be fit into 2530 5 times, resulting in a remainder of 205.
Use 5 as the next digit of our solution. 
Result so far: 193855.5
If we take 2325 away from 2530, we end up with 205.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2050, and continue the process.

On to step 10:
465 can be fit into 2050 4 times, resulting in a remainder of 190.
Put 4 as the next digit of the answer. 
Result so far: 193855.54
The remainder is 190 after subtracting 1860 from 2050.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Going ahead to step 11:
When dividing 1900 by 465, we get 4 with a remainder of 40.
The number 4 becomes the next digit in our result. 
Result so far: 193855.544
Subtracting 1860 from 1900 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

After the division, we end up with 193855.544 and a remainder of 0.004.
