48380084 ÷ 405 
The aim is to understand the frequency of 405 in 48380084.

On to step 1:
4 divided by 405 is 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Bring next digit (8) of the dividend behind the 4 and repeat the process: 48 / 405

Advancing to step 2:
If we divide 48 by 405, we get 0 and a remainder of 48.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 48, we get 48.
Fetch the next digit (3) from the dividend, attach it to 48 and continue: 483 / 405

Moving on to step 3:
If we divide 483 by 405, we get 1 and a remainder of 78.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 78 after subtracting 405 from 483.
Bring next digit (8) of the dividend behind the 78 and repeat the process: 788 / 405

Advancing to step 4:
405 goes into 788 1 times with a remainder of 383.
Write down 1 as next digit of the result. 
Result so far: 11.0
If we subtract 405 from 788, we get 383.
Take the next digit (0) from the dividend and append it to 383, then repeat: 3830 / 405

Going ahead to step 5:
When dividing 3830 by 405, we get 9 with a remainder of 185.
Use 9 as the next digit of our solution. 
Result so far: 119.0
Deduct 3645 from 3830 and we're left with 185.
Append the next digit (0) from the dividend to 185 and continue with: 1850 / 405

Step 6:
405 can be fit into 1850 4 times, resulting in a remainder of 230.
Use 4 as the next digit of our solution. 
Result so far: 1194.0
Subtract 1620 from 1850 to get 230.
Fetch the next digit (8) from the dividend, attach it to 230 and continue: 2308 / 405

Moving on to step 7:
405 goes into 2308 5 times with a remainder of 283.
The number 5 becomes the next digit in our result. 
Result so far: 11945.0
The remainder is 283 after subtracting 2025 from 2308.
Fetch the next digit (4) from the dividend, attach it to 283 and continue: 2834 / 405

Moving on to step 8:
If we divide 2834 by 405, we get 6 and a remainder of 404.
Write down 6 as next digit of the result. 
Result so far: 119456.0
If we subtract 2430 from 2834, we get 404.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4040, and continue the process.

On to step 9:
405 can be fit into 4040 9 times, resulting in a remainder of 395.
Use 9 as the next digit of our solution. 
Result so far: 119456.9
If we take 3645 away from 4040, we end up with 395.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3950, and continue the process.

Moving on to step 10:
3950 divided by 405 is 9 with a remainder of 305.
Write down 9 as next digit of the result. 
Result so far: 119456.99
Subtracting 3645 from 3950 leaves us with 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 final outcome is 119456.99, with a leftover of 0.305.
