12464286 divided by 419 
The aim is to understand the frequency of 419 in 12464286.

On to step 1:
1 divided by 419 is 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 419

Going ahead to step 2:
419 can be fit into 12 0 times, resulting in a remainder of 12.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 12, we end up with 12.
Append the next digit (4) from the dividend to 12 and continue with: 124 / 419

Moving on to step 3:
When dividing 124 by 419, we get 0 with a remainder of 124.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 124, we get 124.
Append the next digit (6) from the dividend to 124 and continue with: 1246 / 419

Let's proceed to step 4:
1246 divided by 419 is 2 with a remainder of 408.
Put 2 as the next digit of the answer. 
Result so far: 2.0
The remainder is 408 after subtracting 838 from 1246.
Take the next digit (4) from the dividend and append it to 408, then repeat: 4084 / 419

Moving on to step 5:
4084 divided by 419 is 9 with a remainder of 313.
Use 9 as the next digit of our solution. 
Result so far: 29.0
If we subtract 3771 from 4084, we get 313.
Bring next digit (2) of the dividend behind the 313 and repeat the process: 3132 / 419

Advancing to step 6:
419 can be fit into 3132 7 times, resulting in a remainder of 199.
Record the quotient 7 as the next digit in the result. 
Result so far: 297.0
Subtract 2933 from 3132 to get 199.
Take the next digit (8) from the dividend and append it to 199, then repeat: 1998 / 419

Going ahead to step 7:
419 goes into 1998 4 times with a remainder of 322.
Put 4 as the next digit of the answer. 
Result so far: 2974.0
If we subtract 1676 from 1998, we get 322.
Fetch the next digit (6) from the dividend, attach it to 322 and continue: 3226 / 419

Step 8:
419 can be fit into 3226 7 times, resulting in a remainder of 293.
The next digit of our result is 7. 
Result so far: 29747.0
Subtract 2933 from 3226 to get 293.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2930, and continue the process.

Step 9:
When dividing 2930 by 419, we get 6 with a remainder of 416.
The next digit of our result is 6. 
Result so far: 29747.6
If we subtract 2514 from 2930, we get 416.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4160, and continue the process.

Advancing to step 10:
4160 divided by 419 is 9 with a remainder of 389.
Record the quotient 9 as the next digit in the result. 
Result so far: 29747.69
Subtracting 3771 from 4160 leaves us with 389.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3890, and continue the process.

Moving on to step 11:
3890 divided by 419 is 9 with a remainder of 119.
Record the quotient 9 as the next digit in the result. 
Result so far: 29747.699
Deduct 3771 from 3890 and we're left with 119.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1190, and continue the process.

The final outcome is 29747.699, with a leftover of 0.0119.
