42020619 ÷ 417 
The aim is to understand the frequency of 417 in 42020619.

On to step 1:
If we divide 4 by 417, we get 0 and a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Fetch the next digit (2) from the dividend, attach it to 4 and continue: 42 / 417

Let's proceed to step 2:
If we divide 42 by 417, we get 0 and a remainder of 42.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 42 after subtracting 0 from 42.
Grab the next digit (0) from the dividend, add it to 42, then carry on: 420 / 417

Advancing to step 3:
When dividing 420 by 417, we get 1 with a remainder of 3.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 417 away from 420, we end up with 3.
Include the next digit (2) from the dividend after 3, then repeat: 32 / 417

Step 4:
417 can be fit into 32 0 times, resulting in a remainder of 32.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
The remainder is 32 after subtracting 0 from 32.
Include the next digit (0) from the dividend after 32, then repeat: 320 / 417

Moving on to step 5:
417 can be fit into 320 0 times, resulting in a remainder of 320.
Put 0 as the next digit of the answer. 
Result so far: 100.0
Deduct 0 from 320 and we're left with 320.
Include the next digit (6) from the dividend after 320, then repeat: 3206 / 417

Step 6:
417 goes into 3206 7 times with a remainder of 287.
Use 7 as the next digit of our solution. 
Result so far: 1007.0
Subtracting 2919 from 3206 leaves us with 287.
Append the next digit (1) from the dividend to 287 and continue with: 2871 / 417

Going ahead to step 7:
When dividing 2871 by 417, we get 6 with a remainder of 369.
The next digit of our result is 6. 
Result so far: 10076.0
Subtracting 2502 from 2871 leaves us with 369.
Take the next digit (9) from the dividend and append it to 369, then repeat: 3699 / 417

On to step 8:
The number 417 fits into 3699 8 times, leaving a remainder of 363.
Write down 8 as next digit of the result. 
Result so far: 100768.0
Deduct 3336 from 3699 and we're left with 363.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3630, and continue the process.

Let's proceed to step 9:
417 can be fit into 3630 8 times, resulting in a remainder of 294.
Write down 8 as next digit of the result. 
Result so far: 100768.8
Subtracting 3336 from 3630 leaves us with 294.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2940, and continue the process.

Let's proceed to step 10:
The number 417 fits into 2940 7 times, leaving a remainder of 21.
Write down 7 as next digit of the result. 
Result so far: 100768.87
Subtract 2919 from 2940 to get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Let's proceed to step 11:
417 goes into 210 0 times with a remainder of 210.
The number 0 becomes the next digit in our result. 
Result so far: 100768.87
Subtract 0 from 210 to get 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Advancing to step 12:
The number 417 fits into 2100 5 times, leaving a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 100768.8705
The remainder is 15 after subtracting 2085 from 2100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 13:
When dividing 150 by 417, we get 0 with a remainder of 150.
Write down 0 as next digit of the result. 
Result so far: 100768.8705
Deduct 0 from 150 and we're left with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Moving on to step 14:
417 goes into 1500 3 times with a remainder of 249.
Use 3 as the next digit of our solution. 
Result so far: 100768.870503
If we take 1251 away from 1500, we end up with 249.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2490, and continue the process.

On to step 15:
When dividing 2490 by 417, we get 5 with a remainder of 405.
The number 5 becomes the next digit in our result. 
Result so far: 100768.8705035
If we take 2085 away from 2490, we end up with 405.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4050, and continue the process.

Going ahead to step 16:
4050 divided by 417 is 9 with a remainder of 297.
Use 9 as the next digit of our solution. 
Result so far: 100768.87050359
The remainder is 297 after subtracting 3753 from 4050.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2970, and continue the process.

The final outcome is 100768.87050359, with a leftover of 2.97e-07.
