We look at the division of 3371575 by 419 
The aim is to understand the frequency of 419 in 3371575.

Step 1:
If we divide 3 by 419, we get 0 and a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Take the next digit (3) from the dividend and append it to 3, then repeat: 33 / 419

Step 2:
When dividing 33 by 419, we get 0 with a remainder of 33.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 33 leaves us with 33.
Grab the next digit (7) from the dividend, add it to 33, then carry on: 337 / 419

Let's proceed to step 3:
337 divided by 419 is 0 with a remainder of 337.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 337 to get 337.
Take the next digit (1) from the dividend and append it to 337, then repeat: 3371 / 419

Step 4:
3371 divided by 419 is 8 with a remainder of 19.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Subtracting 3352 from 3371 leaves us with 19.
Bring next digit (5) of the dividend behind the 19 and repeat the process: 195 / 419

Advancing to step 5:
When dividing 195 by 419, we get 0 with a remainder of 195.
The next digit of our result is 0. 
Result so far: 80.0
Subtracting 0 from 195 leaves us with 195.
Bring next digit (7) of the dividend behind the 195 and repeat the process: 1957 / 419

Step 6:
1957 divided by 419 is 4 with a remainder of 281.
Use 4 as the next digit of our solution. 
Result so far: 804.0
The remainder is 281 after subtracting 1676 from 1957.
Fetch the next digit (5) from the dividend, attach it to 281 and continue: 2815 / 419

Moving on to step 7:
The number 419 fits into 2815 6 times, leaving a remainder of 301.
Write down 6 as next digit of the result. 
Result so far: 8046.0
The remainder is 301 after subtracting 2514 from 2815.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3010, and continue the process.

Advancing to step 8:
When dividing 3010 by 419, we get 7 with a remainder of 77.
Record the quotient 7 as the next digit in the result. 
Result so far: 8046.7
Deduct 2933 from 3010 and we're left with 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Going ahead to step 9:
770 divided by 419 is 1 with a remainder of 351.
Put 1 as the next digit of the answer. 
Result so far: 8046.71
The remainder is 351 after subtracting 419 from 770.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3510, and continue the process.

Going ahead to step 10:
When dividing 3510 by 419, we get 8 with a remainder of 158.
Put 8 as the next digit of the answer. 
Result so far: 8046.718
The remainder is 158 after subtracting 3352 from 3510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1580, and continue the process.

Advancing to step 11:
The number 419 fits into 1580 3 times, leaving a remainder of 323.
Put 3 as the next digit of the answer. 
Result so far: 8046.7183
Subtract 1257 from 1580 to get 323.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3230, and continue the process.

Advancing to step 12:
3230 divided by 419 is 7 with a remainder of 297.
Record the quotient 7 as the next digit in the result. 
Result so far: 8046.71837
The remainder is 297 after subtracting 2933 from 3230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2970, and continue the process.

Let's proceed to step 13:
The number 419 fits into 2970 7 times, leaving a remainder of 37.
The number 7 becomes the next digit in our result. 
Result so far: 8046.718377
Subtract 2933 from 2970 to get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

The final result is 8046.718377 with a remainder of 3.7e-06.
