709019 ÷ 42 
The aim is to understand the frequency of 42 in 709019.

Step 1:
42 goes into 7 0 times with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Grab the next digit (0) from the dividend, add it to 7, then carry on: 70 / 42

Going ahead to step 2:
When dividing 70 by 42, we get 1 with a remainder of 28.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 42 from 70 and we're left with 28.
Include the next digit (9) from the dividend after 28, then repeat: 289 / 42

Let's proceed to step 3:
289 divided by 42 is 6 with a remainder of 37.
Use 6 as the next digit of our solution. 
Result so far: 16.0
Subtracting 252 from 289 leaves us with 37.
Include the next digit (0) from the dividend after 37, then repeat: 370 / 42

Let's proceed to step 4:
When dividing 370 by 42, we get 8 with a remainder of 34.
Use 8 as the next digit of our solution. 
Result so far: 168.0
Subtracting 336 from 370 leaves us with 34.
Take the next digit (1) from the dividend and append it to 34, then repeat: 341 / 42

Going ahead to step 5:
If we divide 341 by 42, we get 8 and a remainder of 5.
The number 8 becomes the next digit in our result. 
Result so far: 1688.0
Subtract 336 from 341 to get 5.
Take the next digit (9) from the dividend and append it to 5, then repeat: 59 / 42

Step 6:
42 goes into 59 1 times with a remainder of 17.
Put 1 as the next digit of the answer. 
Result so far: 16881.0
If we take 42 away from 59, we end up with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Moving on to step 7:
42 goes into 170 4 times with a remainder of 2.
The number 4 becomes the next digit in our result. 
Result so far: 16881.4
If we subtract 168 from 170, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 8:
20 divided by 42 is 0 with a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 16881.4
Subtracting 0 from 20 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 9:
If we divide 200 by 42, we get 4 and a remainder of 32.
Write down 4 as next digit of the result. 
Result so far: 16881.404
If we take 168 away from 200, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 10:
If we divide 320 by 42, we get 7 and a remainder of 26.
Use 7 as the next digit of our solution. 
Result so far: 16881.4047
Deduct 294 from 320 and we're left with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Let's proceed to step 11:
42 can be fit into 260 6 times, resulting in a remainder of 8.
Record the quotient 6 as the next digit in the result. 
Result so far: 16881.40476
If we subtract 252 from 260, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 12:
80 divided by 42 is 1 with a remainder of 38.
Put 1 as the next digit of the answer. 
Result so far: 16881.404761
Subtract 42 from 80 to get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Moving on to step 13:
380 divided by 42 is 9 with a remainder of 2.
The number 9 becomes the next digit in our result. 
Result so far: 16881.4047619
If we subtract 378 from 380, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 14:
20 divided by 42 is 0 with a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 16881.4047619
Deduct 0 from 20 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The final outcome is 16881.4047619, with a leftover of 2e-08.
