We're dividing 8466278 by 419 
The aim is to understand the frequency of 419 in 8466278.

Let's proceed to step 1:
The number 419 fits into 8 0 times, leaving a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Include the next digit (4) from the dividend after 8, then repeat: 84 / 419

Step 2:
419 can be fit into 84 0 times, resulting in a remainder of 84.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 84 and we're left with 84.
Include the next digit (6) from the dividend after 84, then repeat: 846 / 419

On to step 3:
If we divide 846 by 419, we get 2 and a remainder of 8.
Write down 2 as next digit of the result. 
Result so far: 2.0
Deduct 838 from 846 and we're left with 8.
Fetch the next digit (6) from the dividend, attach it to 8 and continue: 86 / 419

Step 4:
419 can be fit into 86 0 times, resulting in a remainder of 86.
Use 0 as the next digit of our solution. 
Result so far: 20.0
Subtracting 0 from 86 leaves us with 86.
Take the next digit (2) from the dividend and append it to 86, then repeat: 862 / 419

Advancing to step 5:
When dividing 862 by 419, we get 2 with a remainder of 24.
The next digit of our result is 2. 
Result so far: 202.0
The remainder is 24 after subtracting 838 from 862.
Fetch the next digit (7) from the dividend, attach it to 24 and continue: 247 / 419

On to step 6:
419 can be fit into 247 0 times, resulting in a remainder of 247.
The number 0 becomes the next digit in our result. 
Result so far: 2020.0
The remainder is 247 after subtracting 0 from 247.
Bring next digit (8) of the dividend behind the 247 and repeat the process: 2478 / 419

Step 7:
419 can be fit into 2478 5 times, resulting in a remainder of 383.
Record the quotient 5 as the next digit in the result. 
Result so far: 20205.0
Subtract 2095 from 2478 to get 383.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3830, and continue the process.

Let's proceed to step 8:
When dividing 3830 by 419, we get 9 with a remainder of 59.
The next digit of our result is 9. 
Result so far: 20205.9
If we subtract 3771 from 3830, we get 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Advancing to step 9:
419 goes into 590 1 times with a remainder of 171.
The next digit of our result is 1. 
Result so far: 20205.91
If we take 419 away from 590, we end up with 171.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1710, and continue the process.

Going ahead to step 10:
If we divide 1710 by 419, we get 4 and a remainder of 34.
Use 4 as the next digit of our solution. 
Result so far: 20205.914
The remainder is 34 after subtracting 1676 from 1710.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Step 11:
The number 419 fits into 340 0 times, leaving a remainder of 340.
Use 0 as the next digit of our solution. 
Result so far: 20205.914
Subtracting 0 from 340 leaves us with 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Let's proceed to step 12:
When dividing 3400 by 419, we get 8 with a remainder of 48.
Write down 8 as next digit of the result. 
Result so far: 20205.91408
If we subtract 3352 from 3400, we get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Step 13:
480 divided by 419 is 1 with a remainder of 61.
The number 1 becomes the next digit in our result. 
Result so far: 20205.914081
If we subtract 419 from 480, we get 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Going ahead to step 14:
419 goes into 610 1 times with a remainder of 191.
Write down 1 as next digit of the result. 
Result so far: 20205.9140811
The remainder is 191 after subtracting 419 from 610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1910, and continue the process.

The final outcome is 20205.9140811, with a leftover of 1.91e-06.
