Let's divide 20390336 by 417
The aim is to understand the frequency of 417 in 20390336.

Let's proceed to step 1:
2 divided by 417 is 0 with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Grab the next digit (0) from the dividend, add it to 2, then carry on: 20 / 417

On to step 2:
417 goes into 20 0 times with a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 20 leaves us with 20.
Fetch the next digit (3) from the dividend, attach it to 20 and continue: 203 / 417

Step 3:
If we divide 203 by 417, we get 0 and a remainder of 203.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 203 to get 203.
Fetch the next digit (9) from the dividend, attach it to 203 and continue: 2039 / 417

Advancing to step 4:
If we divide 2039 by 417, we get 4 and a remainder of 371.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Subtracting 1668 from 2039 leaves us with 371.
Include the next digit (0) from the dividend after 371, then repeat: 3710 / 417

Moving on to step 5:
417 can be fit into 3710 8 times, resulting in a remainder of 374.
Put 8 as the next digit of the answer. 
Result so far: 48.0
Subtract 3336 from 3710 to get 374.
Fetch the next digit (3) from the dividend, attach it to 374 and continue: 3743 / 417

Going ahead to step 6:
417 can be fit into 3743 8 times, resulting in a remainder of 407.
The number 8 becomes the next digit in our result. 
Result so far: 488.0
Subtracting 3336 from 3743 leaves us with 407.
Bring next digit (3) of the dividend behind the 407 and repeat the process: 4073 / 417

Going ahead to step 7:
4073 divided by 417 is 9 with a remainder of 320.
The next digit of our result is 9. 
Result so far: 4889.0
Deduct 3753 from 4073 and we're left with 320.
Take the next digit (6) from the dividend and append it to 320, then repeat: 3206 / 417

Moving on to step 8:
The number 417 fits into 3206 7 times, leaving a remainder of 287.
Put 7 as the next digit of the answer. 
Result so far: 48897.0
Subtracting 2919 from 3206 leaves us with 287.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2870, and continue the process.

On to step 9:
417 can be fit into 2870 6 times, resulting in a remainder of 368.
The next digit of our result is 6. 
Result so far: 48897.6
Subtracting 2502 from 2870 leaves us with 368.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

Advancing to step 10:
417 goes into 3680 8 times with a remainder of 344.
Record the quotient 8 as the next digit in the result. 
Result so far: 48897.68
Subtracting 3336 from 3680 leaves us with 344.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3440, and continue the process.

On to step 11:
If we divide 3440 by 417, we get 8 and a remainder of 104.
The number 8 becomes the next digit in our result. 
Result so far: 48897.688
Deduct 3336 from 3440 and we're left with 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

The quotient of the division is 48897.688, and the remainder is 0.0104.
