We divide 85766671 by 405
The aim is to understand the frequency of 405 in 85766671.

Let's proceed to step 1:
When dividing 8 by 405, we get 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Bring next digit (5) of the dividend behind the 8 and repeat the process: 85 / 405

Step 2:
405 goes into 85 0 times with a remainder of 85.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 85, we get 85.
Bring next digit (7) of the dividend behind the 85 and repeat the process: 857 / 405

Moving on to step 3:
405 goes into 857 2 times with a remainder of 47.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we subtract 810 from 857, we get 47.
Bring next digit (6) of the dividend behind the 47 and repeat the process: 476 / 405

Advancing to step 4:
The number 405 fits into 476 1 times, leaving a remainder of 71.
The next digit of our result is 1. 
Result so far: 21.0
If we subtract 405 from 476, we get 71.
Fetch the next digit (6) from the dividend, attach it to 71 and continue: 716 / 405

Going ahead to step 5:
The number 405 fits into 716 1 times, leaving a remainder of 311.
The number 1 becomes the next digit in our result. 
Result so far: 211.0
If we subtract 405 from 716, we get 311.
Append the next digit (6) from the dividend to 311 and continue with: 3116 / 405

Step 6:
405 goes into 3116 7 times with a remainder of 281.
Use 7 as the next digit of our solution. 
Result so far: 2117.0
Deduct 2835 from 3116 and we're left with 281.
Fetch the next digit (7) from the dividend, attach it to 281 and continue: 2817 / 405

Going ahead to step 7:
The number 405 fits into 2817 6 times, leaving a remainder of 387.
Use 6 as the next digit of our solution. 
Result so far: 21176.0
Deduct 2430 from 2817 and we're left with 387.
Include the next digit (1) from the dividend after 387, then repeat: 3871 / 405

Advancing to step 8:
If we divide 3871 by 405, we get 9 and a remainder of 226.
Use 9 as the next digit of our solution. 
Result so far: 211769.0
Deduct 3645 from 3871 and we're left with 226.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2260, and continue the process.

Going ahead to step 9:
If we divide 2260 by 405, we get 5 and a remainder of 235.
The number 5 becomes the next digit in our result. 
Result so far: 211769.5
Subtracting 2025 from 2260 leaves us with 235.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2350, and continue the process.

Advancing to step 10:
405 can be fit into 2350 5 times, resulting in a remainder of 325.
The number 5 becomes the next digit in our result. 
Result so far: 211769.55
If we take 2025 away from 2350, we end up with 325.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3250, and continue the process.

The final result is 211769.55 with a remainder of 0.325.
