We look at the division of 53043219 by 417 
The aim is to understand the frequency of 417 in 53043219.

Advancing to step 1:
If we divide 5 by 417, we get 0 and a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Append the next digit (3) from the dividend to 5 and continue with: 53 / 417

Step 2:
When dividing 53 by 417, we get 0 with a remainder of 53.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 53, we get 53.
Include the next digit (0) from the dividend after 53, then repeat: 530 / 417

Going ahead to step 3:
If we divide 530 by 417, we get 1 and a remainder of 113.
The next digit of our result is 1. 
Result so far: 1.0
If we take 417 away from 530, we end up with 113.
Bring next digit (4) of the dividend behind the 113 and repeat the process: 1134 / 417

Going ahead to step 4:
The number 417 fits into 1134 2 times, leaving a remainder of 300.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
Deduct 834 from 1134 and we're left with 300.
Take the next digit (3) from the dividend and append it to 300, then repeat: 3003 / 417

Moving on to step 5:
417 can be fit into 3003 7 times, resulting in a remainder of 84.
The next digit of our result is 7. 
Result so far: 127.0
If we subtract 2919 from 3003, we get 84.
Include the next digit (2) from the dividend after 84, then repeat: 842 / 417

On to step 6:
If we divide 842 by 417, we get 2 and a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 1272.0
Subtract 834 from 842 to get 8.
Append the next digit (1) from the dividend to 8 and continue with: 81 / 417

Moving on to step 7:
When dividing 81 by 417, we get 0 with a remainder of 81.
Record the quotient 0 as the next digit in the result. 
Result so far: 12720.0
If we take 0 away from 81, we end up with 81.
Fetch the next digit (9) from the dividend, attach it to 81 and continue: 819 / 417

Let's proceed to step 8:
819 divided by 417 is 1 with a remainder of 402.
The number 1 becomes the next digit in our result. 
Result so far: 127201.0
Deduct 417 from 819 and we're left with 402.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4020, and continue the process.

Let's proceed to step 9:
When dividing 4020 by 417, we get 9 with a remainder of 267.
Put 9 as the next digit of the answer. 
Result so far: 127201.9
If we take 3753 away from 4020, we end up with 267.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2670, and continue the process.

Moving on to step 10:
417 goes into 2670 6 times with a remainder of 168.
Record the quotient 6 as the next digit in the result. 
Result so far: 127201.96
If we take 2502 away from 2670, we end up with 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

Step 11:
1680 divided by 417 is 4 with a remainder of 12.
Use 4 as the next digit of our solution. 
Result so far: 127201.964
Deduct 1668 from 1680 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 12:
417 can be fit into 120 0 times, resulting in a remainder of 120.
Use 0 as the next digit of our solution. 
Result so far: 127201.964
The remainder is 120 after subtracting 0 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Going ahead to step 13:
417 goes into 1200 2 times with a remainder of 366.
The number 2 becomes the next digit in our result. 
Result so far: 127201.96402
Subtracting 834 from 1200 leaves us with 366.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3660, and continue the process.

Going ahead to step 14:
3660 divided by 417 is 8 with a remainder of 324.
Use 8 as the next digit of our solution. 
Result so far: 127201.964028
If we take 3336 away from 3660, we end up with 324.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3240, and continue the process.

Let's proceed to step 15:
The number 417 fits into 3240 7 times, leaving a remainder of 321.
The number 7 becomes the next digit in our result. 
Result so far: 127201.9640287
Subtracting 2919 from 3240 leaves us with 321.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3210, and continue the process.

Step 16:
When dividing 3210 by 417, we get 7 with a remainder of 291.
The number 7 becomes the next digit in our result. 
Result so far: 127201.96402877
Subtracting 2919 from 3210 leaves us with 291.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2910, and continue the process.

The final result is 127201.96402877 with a remainder of 2.91e-07.
