We're dividing 3027471 by 405 
The aim is to understand the frequency of 405 in 3027471.

Going ahead to step 1:
When dividing 3 by 405, we get 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Take the next digit (0) from the dividend and append it to 3, then repeat: 30 / 405

Moving on to step 2:
30 divided by 405 is 0 with a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 30 and we're left with 30.
Append the next digit (2) from the dividend to 30 and continue with: 302 / 405

On to step 3:
When dividing 302 by 405, we get 0 with a remainder of 302.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 302, we get 302.
Bring next digit (7) of the dividend behind the 302 and repeat the process: 3027 / 405

Let's proceed to step 4:
When dividing 3027 by 405, we get 7 with a remainder of 192.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
If we subtract 2835 from 3027, we get 192.
Bring next digit (4) of the dividend behind the 192 and repeat the process: 1924 / 405

Moving on to step 5:
405 can be fit into 1924 4 times, resulting in a remainder of 304.
Put 4 as the next digit of the answer. 
Result so far: 74.0
Subtract 1620 from 1924 to get 304.
Grab the next digit (7) from the dividend, add it to 304, then carry on: 3047 / 405

Let's proceed to step 6:
When dividing 3047 by 405, we get 7 with a remainder of 212.
Put 7 as the next digit of the answer. 
Result so far: 747.0
Subtract 2835 from 3047 to get 212.
Fetch the next digit (1) from the dividend, attach it to 212 and continue: 2121 / 405

On to step 7:
When dividing 2121 by 405, we get 5 with a remainder of 96.
Put 5 as the next digit of the answer. 
Result so far: 7475.0
Deduct 2025 from 2121 and we're left with 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Let's proceed to step 8:
960 divided by 405 is 2 with a remainder of 150.
Write down 2 as next digit of the result. 
Result so far: 7475.2
If we take 810 away from 960, we end up with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

On to step 9:
1500 divided by 405 is 3 with a remainder of 285.
The number 3 becomes the next digit in our result. 
Result so far: 7475.23
Subtract 1215 from 1500 to get 285.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2850, and continue the process.

Going ahead to step 10:
When dividing 2850 by 405, we get 7 with a remainder of 15.
Put 7 as the next digit of the answer. 
Result so far: 7475.237
Subtracting 2835 from 2850 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 11:
405 can be fit into 150 0 times, resulting in a remainder of 150.
Record the quotient 0 as the next digit in the result. 
Result so far: 7475.237
Subtract 0 from 150 to get 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Let's proceed to step 12:
When dividing 1500 by 405, we get 3 with a remainder of 285.
The number 3 becomes the next digit in our result. 
Result so far: 7475.23703
If we take 1215 away from 1500, we end up 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.

Advancing to step 13:
When dividing 2850 by 405, we get 7 with a remainder of 15.
The next digit of our result is 7. 
Result so far: 7475.237037
If we subtract 2835 from 2850, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 14:
405 can be fit into 150 0 times, resulting in a remainder of 150.
Write down 0 as next digit of the result. 
Result so far: 7475.237037
If we take 0 away from 150, we end up with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Advancing to step 15:
The number 405 fits into 1500 3 times, leaving a remainder of 285.
Put 3 as the next digit of the answer. 
Result so far: 7475.23703703
Subtracting 1215 from 1500 leaves us 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.

The final outcome is 7475.23703703, with a leftover of 2.85e-07.
