We look at the division of 41351671 by 417 
The aim is to understand the frequency of 417 in 41351671.

On to step 1:
If we divide 4 by 417, we get 0 and a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Take the next digit (1) from the dividend and append it to 4, then repeat: 41 / 417

Advancing to step 2:
The number 417 fits into 41 0 times, leaving a remainder of 41.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 41 leaves us with 41.
Include the next digit (3) from the dividend after 41, then repeat: 413 / 417

On to step 3:
The number 417 fits into 413 0 times, leaving a remainder of 413.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 413 and we're left with 413.
Append the next digit (5) from the dividend to 413 and continue with: 4135 / 417

Advancing to step 4:
4135 divided by 417 is 9 with a remainder of 382.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
If we subtract 3753 from 4135, we get 382.
Append the next digit (1) from the dividend to 382 and continue with: 3821 / 417

On to step 5:
When dividing 3821 by 417, we get 9 with a remainder of 68.
Write down 9 as next digit of the result. 
Result so far: 99.0
If we take 3753 away from 3821, we end up with 68.
Bring next digit (6) of the dividend behind the 68 and repeat the process: 686 / 417

On to step 6:
686 divided by 417 is 1 with a remainder of 269.
Record the quotient 1 as the next digit in the result. 
Result so far: 991.0
The remainder is 269 after subtracting 417 from 686.
Fetch the next digit (7) from the dividend, attach it to 269 and continue: 2697 / 417

Step 7:
If we divide 2697 by 417, we get 6 and a remainder of 195.
The next digit of our result is 6. 
Result so far: 9916.0
If we take 2502 away from 2697, we end up with 195.
Bring next digit (1) of the dividend behind the 195 and repeat the process: 1951 / 417

Moving on to step 8:
1951 divided by 417 is 4 with a remainder of 283.
Put 4 as the next digit of the answer. 
Result so far: 99164.0
Subtract 1668 from 1951 to get 283.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2830, and continue the process.

Let's proceed to step 9:
If we divide 2830 by 417, we get 6 and a remainder of 328.
Write down 6 as next digit of the result. 
Result so far: 99164.6
If we take 2502 away from 2830, we end up with 328.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3280, and continue the process.

Moving on to step 10:
3280 divided by 417 is 7 with a remainder of 361.
Write down 7 as next digit of the result. 
Result so far: 99164.67
The remainder is 361 after subtracting 2919 from 3280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3610, and continue the process.

On to step 11:
When dividing 3610 by 417, we get 8 with a remainder of 274.
The number 8 becomes the next digit in our result. 
Result so far: 99164.678
Deduct 3336 from 3610 and we're left with 274.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2740, and continue the process.

Step 12:
417 goes into 2740 6 times with a remainder of 238.
The next digit of our result is 6. 
Result so far: 99164.6786
If we take 2502 away from 2740, we end up with 238.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2380, and continue the process.

On to step 13:
417 goes into 2380 5 times with a remainder of 295.
Write down 5 as next digit of the result. 
Result so far: 99164.67865
If we subtract 2085 from 2380, we get 295.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2950, and continue the process.

Let's proceed to step 14:
417 can be fit into 2950 7 times, resulting in a remainder of 31.
Put 7 as the next digit of the answer. 
Result so far: 99164.678657
If we take 2919 away from 2950, we end up with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Let's proceed to step 15:
310 divided by 417 is 0 with a remainder of 310.
Record the quotient 0 as the next digit in the result. 
Result so far: 99164.678657
Subtract 0 from 310 to get 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

Moving on to step 16:
If we divide 3100 by 417, we get 7 and a remainder of 181.
Put 7 as the next digit of the answer. 
Result so far: 99164.67865707
Subtract 2919 from 3100 to get 181.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1810, and continue the process.

After the division, we end up with 99164.67865707 and a remainder of 1.81e-07.
