42018559 divided by 613 
The aim is to understand the frequency of 613 in 42018559.

On to step 1:
4 divided by 613 is 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Fetch the next digit (2) from the dividend, attach it to 4 and continue: 42 / 613

Moving on to step 2:
42 divided by 613 is 0 with a remainder of 42.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 42 to get 42.
Append the next digit (0) from the dividend to 42 and continue with: 420 / 613

Step 3:
420 divided by 613 is 0 with a remainder of 420.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 420 and we're left with 420.
Include the next digit (1) from the dividend after 420, then repeat: 4201 / 613

Moving on to step 4:
613 can be fit into 4201 6 times, resulting in a remainder of 523.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
The remainder is 523 after subtracting 3678 from 4201.
Take the next digit (8) from the dividend and append it to 523, then repeat: 5238 / 613

Let's proceed to step 5:
The number 613 fits into 5238 8 times, leaving a remainder of 334.
The next digit of our result is 8. 
Result so far: 68.0
Deduct 4904 from 5238 and we're left with 334.
Grab the next digit (5) from the dividend, add it to 334, then carry on: 3345 / 613

Let's proceed to step 6:
613 can be fit into 3345 5 times, resulting in a remainder of 280.
Write down 5 as next digit of the result. 
Result so far: 685.0
If we subtract 3065 from 3345, we get 280.
Bring next digit (5) of the dividend behind the 280 and repeat the process: 2805 / 613

Going ahead to step 7:
613 can be fit into 2805 4 times, resulting in a remainder of 353.
The number 4 becomes the next digit in our result. 
Result so far: 6854.0
The remainder is 353 after subtracting 2452 from 2805.
Include the next digit (9) from the dividend after 353, then repeat: 3539 / 613

Let's proceed to step 8:
When dividing 3539 by 613, we get 5 with a remainder of 474.
Put 5 as the next digit of the answer. 
Result so far: 68545.0
If we subtract 3065 from 3539, we get 474.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4740, and continue the process.

Let's proceed to step 9:
When dividing 4740 by 613, we get 7 with a remainder of 449.
Use 7 as the next digit of our solution. 
Result so far: 68545.7
The remainder is 449 after subtracting 4291 from 4740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4490, and continue the process.

On to step 10:
The number 613 fits into 4490 7 times, leaving a remainder of 199.
Record the quotient 7 as the next digit in the result. 
Result so far: 68545.77
Subtracting 4291 from 4490 leaves us with 199.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1990, and continue the process.

The final result is 68545.77 with a remainder of 0.199.
