Let's divide 659611 by 42
The aim is to understand the frequency of 42 in 659611.

Step 1:
When dividing 6 by 42, we get 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Take the next digit (5) from the dividend and append it to 6, then repeat: 65 / 42

Let's proceed to step 2:
If we divide 65 by 42, we get 1 and a remainder of 23.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 42 from 65 to get 23.
Fetch the next digit (9) from the dividend, attach it to 23 and continue: 239 / 42

Let's proceed to step 3:
The number 42 fits into 239 5 times, leaving a remainder of 29.
The next digit of our result is 5. 
Result so far: 15.0
Subtracting 210 from 239 leaves us with 29.
Bring next digit (6) of the dividend behind the 29 and repeat the process: 296 / 42

Step 4:
The number 42 fits into 296 7 times, leaving a remainder of 2.
The number 7 becomes the next digit in our result. 
Result so far: 157.0
Deduct 294 from 296 and we're left with 2.
Append the next digit (1) from the dividend to 2 and continue with: 21 / 42

On to step 5:
The number 42 fits into 21 0 times, leaving a remainder of 21.
The number 0 becomes the next digit in our result. 
Result so far: 1570.0
If we subtract 0 from 21, we get 21.
Bring next digit (1) of the dividend behind the 21 and repeat the process: 211 / 42

Going ahead to step 6:
42 goes into 211 5 times with a remainder of 1.
Record the quotient 5 as the next digit in the result. 
Result so far: 15705.0
If we subtract 210 from 211, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 7:
When dividing 10 by 42, we get 0 with a remainder of 10.
The next digit of our result is 0. 
Result so far: 15705.0
If we subtract 0 from 10, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 8:
100 divided by 42 is 2 with a remainder of 16.
The number 2 becomes the next digit in our result. 
Result so far: 15705.02
Subtract 84 from 100 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 9:
If we divide 160 by 42, we get 3 and a remainder of 34.
The next digit of our result is 3. 
Result so far: 15705.023
If we subtract 126 from 160, we get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Let's proceed to step 10:
The number 42 fits into 340 8 times, leaving a remainder of 4.
The next digit of our result is 8. 
Result so far: 15705.0238
Subtracting 336 from 340 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 11:
The number 42 fits into 40 0 times, leaving a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 15705.0238
Deduct 0 from 40 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 12:
When dividing 400 by 42, we get 9 with a remainder of 22.
The next digit of our result is 9. 
Result so far: 15705.023809
If we subtract 378 from 400, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Going ahead to step 13:
If we divide 220 by 42, we get 5 and a remainder of 10.
Write down 5 as next digit of the result. 
Result so far: 15705.0238095
If we take 210 away from 220, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 14:
The number 42 fits into 100 2 times, leaving a remainder of 16.
The number 2 becomes the next digit in our result. 
Result so far: 15705.02380952
If we subtract 84 from 100, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Our division results in 15705.02380952 with a remaining 1.6e-08.
