We look at the division of 616617 by 42 
The aim is to understand the frequency of 42 in 616617.

Let's proceed to step 1:
42 can be fit into 6 0 times, resulting in a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Fetch the next digit (1) from the dividend, attach it to 6 and continue: 61 / 42

On to step 2:
42 can be fit into 61 1 times, resulting in a remainder of 19.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 42 from 61 and we're left with 19.
Append the next digit (6) from the dividend to 19 and continue with: 196 / 42

Advancing to step 3:
When dividing 196 by 42, we get 4 with a remainder of 28.
Use 4 as the next digit of our solution. 
Result so far: 14.0
The remainder is 28 after subtracting 168 from 196.
Fetch the next digit (6) from the dividend, attach it to 28 and continue: 286 / 42

Let's proceed to step 4:
286 divided by 42 is 6 with a remainder of 34.
Write down 6 as next digit of the result. 
Result so far: 146.0
The remainder is 34 after subtracting 252 from 286.
Fetch the next digit (1) from the dividend, attach it to 34 and continue: 341 / 42

Going ahead to step 5:
42 goes into 341 8 times with a remainder of 5.
The number 8 becomes the next digit in our result. 
Result so far: 1468.0
The remainder is 5 after subtracting 336 from 341.
Take the next digit (7) from the dividend and append it to 5, then repeat: 57 / 42

Let's proceed to step 6:
57 divided by 42 is 1 with a remainder of 15.
Use 1 as the next digit of our solution. 
Result so far: 14681.0
If we take 42 away from 57, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 7:
When dividing 150 by 42, we get 3 with a remainder of 24.
The number 3 becomes the next digit in our result. 
Result so far: 14681.3
The remainder is 24 after subtracting 126 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 8:
240 divided by 42 is 5 with a remainder of 30.
Write down 5 as next digit of the result. 
Result so far: 14681.35
Subtracting 210 from 240 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 9:
When dividing 300 by 42, we get 7 with a remainder of 6.
Write down 7 as next digit of the result. 
Result so far: 14681.357
If we subtract 294 from 300, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 10:
42 can be fit into 60 1 times, resulting in a remainder of 18.
Put 1 as the next digit of the answer. 
Result so far: 14681.3571
The remainder is 18 after subtracting 42 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 11:
42 goes into 180 4 times with a remainder of 12.
The next digit of our result is 4. 
Result so far: 14681.35714
The remainder is 12 after subtracting 168 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 12:
120 divided by 42 is 2 with a remainder of 36.
The next digit of our result is 2. 
Result so far: 14681.357142
Deduct 84 from 120 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 13:
If we divide 360 by 42, we get 8 and a remainder of 24.
Put 8 as the next digit of the answer. 
Result so far: 14681.3571428
Subtract 336 from 360 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 14:
42 can be fit into 240 5 times, resulting in a remainder of 30.
Write down 5 as next digit of the result. 
Result so far: 14681.35714285
If we subtract 210 from 240, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

The final outcome is 14681.35714285, with a leftover of 3e-08.
