We divide 405449 by 85
The aim is to understand the frequency of 85 in 405449.

Moving on to step 1:
85 goes into 4 0 times with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Bring next digit (0) of the dividend behind the 4 and repeat the process: 40 / 85

Let's proceed to step 2:
If we divide 40 by 85, we get 0 and a remainder of 40.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 40, we end up with 40.
Bring next digit (5) of the dividend behind the 40 and repeat the process: 405 / 85

Moving on to step 3:
The number 85 fits into 405 4 times, leaving a remainder of 65.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
If we subtract 340 from 405, we get 65.
Take the next digit (4) from the dividend and append it to 65, then repeat: 654 / 85

On to step 4:
654 divided by 85 is 7 with a remainder of 59.
The number 7 becomes the next digit in our result. 
Result so far: 47.0
Subtracting 595 from 654 leaves us with 59.
Bring next digit (4) of the dividend behind the 59 and repeat the process: 594 / 85

Step 5:
594 divided by 85 is 6 with a remainder of 84.
The number 6 becomes the next digit in our result. 
Result so far: 476.0
Deduct 510 from 594 and we're left with 84.
Fetch the next digit (9) from the dividend, attach it to 84 and continue: 849 / 85

Advancing to step 6:
849 divided by 85 is 9 with a remainder of 84.
The number 9 becomes the next digit in our result. 
Result so far: 4769.0
Deduct 765 from 849 and we're left with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Step 7:
When dividing 840 by 85, we get 9 with a remainder of 75.
The number 9 becomes the next digit in our result. 
Result so far: 4769.9
If we take 765 away from 840, we end up with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Moving on to step 8:
85 goes into 750 8 times with a remainder of 70.
The number 8 becomes the next digit in our result. 
Result so far: 4769.98
If we take 680 away from 750, we end up with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

On to step 9:
The number 85 fits into 700 8 times, leaving a remainder of 20.
The next digit of our result is 8. 
Result so far: 4769.988
If we subtract 680 from 700, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The final result is 4769.988 with a remainder of 0.002.
