Let's divide 67291480 by 405
The aim is to understand the frequency of 405 in 67291480.

Moving on to step 1:
When dividing 6 by 405, we get 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Include the next digit (7) from the dividend after 6, then repeat: 67 / 405

Moving on to step 2:
405 goes into 67 0 times with a remainder of 67.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 67 leaves us with 67.
Take the next digit (2) from the dividend and append it to 67, then repeat: 672 / 405

Advancing to step 3:
405 can be fit into 672 1 times, resulting in a remainder of 267.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 405 from 672 to get 267.
Bring next digit (9) of the dividend behind the 267 and repeat the process: 2679 / 405

Advancing to step 4:
405 can be fit into 2679 6 times, resulting in a remainder of 249.
Put 6 as the next digit of the answer. 
Result so far: 16.0
If we take 2430 away from 2679, we end up with 249.
Append the next digit (1) from the dividend to 249 and continue with: 2491 / 405

On to step 5:
405 goes into 2491 6 times with a remainder of 61.
Put 6 as the next digit of the answer. 
Result so far: 166.0
Deduct 2430 from 2491 and we're left with 61.
Grab the next digit (4) from the dividend, add it to 61, then carry on: 614 / 405

Advancing to step 6:
405 goes into 614 1 times with a remainder of 209.
Write down 1 as next digit of the result. 
Result so far: 1661.0
If we subtract 405 from 614, we get 209.
Append the next digit (8) from the dividend to 209 and continue with: 2098 / 405

Going ahead to step 7:
The number 405 fits into 2098 5 times, leaving a remainder of 73.
Record the quotient 5 as the next digit in the result. 
Result so far: 16615.0
Subtracting 2025 from 2098 leaves us with 73.
Fetch the next digit (0) from the dividend, attach it to 73 and continue: 730 / 405

Going ahead to step 8:
405 goes into 730 1 times with a remainder of 325.
The number 1 becomes the next digit in our result. 
Result so far: 166151.0
If we subtract 405 from 730, we get 325.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3250, and continue the process.

Advancing to step 9:
When dividing 3250 by 405, we get 8 with a remainder of 10.
Use 8 as the next digit of our solution. 
Result so far: 166151.8
If we subtract 3240 from 3250, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 10:
405 can be fit into 100 0 times, resulting in a remainder of 100.
The next digit of our result is 0. 
Result so far: 166151.8
If we subtract 0 from 100, we get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Moving on to step 11:
If we divide 1000 by 405, we get 2 and a remainder of 190.
Record the quotient 2 as the next digit in the result. 
Result so far: 166151.802
Deduct 810 from 1000 and we're left with 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Step 12:
If we divide 1900 by 405, we get 4 and a remainder of 280.
The number 4 becomes the next digit in our result. 
Result so far: 166151.8024
Subtracting 1620 from 1900 leaves us with 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Let's proceed to step 13:
The number 405 fits into 2800 6 times, leaving a remainder of 370.
The next digit of our result is 6. 
Result so far: 166151.80246
If we subtract 2430 from 2800, we get 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3700, and continue the process.

Going ahead to step 14:
405 can be fit into 3700 9 times, resulting in a remainder of 55.
The number 9 becomes the next digit in our result. 
Result so far: 166151.802469
Subtracting 3645 from 3700 leaves us with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Moving on to step 15:
When dividing 550 by 405, we get 1 with a remainder of 145.
The next digit of our result is 1. 
Result so far: 166151.8024691
Subtracting 405 from 550 leaves us with 145.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

Step 16:
When dividing 1450 by 405, we get 3 with a remainder of 235.
Write down 3 as next digit of the result. 
Result so far: 166151.80246913
If we subtract 1215 from 1450, we get 235.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2350, and continue the process.

The final outcome is 166151.80246913, with a leftover of 2.35e-07.
