Let's divide 971435 by 42
The aim is to understand the frequency of 42 in 971435.

Going ahead to step 1:
The number 42 fits into 9 0 times, leaving a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Include the next digit (7) from the dividend after 9, then repeat: 97 / 42

Advancing to step 2:
If we divide 97 by 42, we get 2 and a remainder of 13.
The next digit of our result is 2. 
Result so far: 2.0
Deduct 84 from 97 and we're left with 13.
Take the next digit (1) from the dividend and append it to 13, then repeat: 131 / 42

Moving on to step 3:
42 goes into 131 3 times with a remainder of 5.
Put 3 as the next digit of the answer. 
Result so far: 23.0
Subtracting 126 from 131 leaves us with 5.
Append the next digit (4) from the dividend to 5 and continue with: 54 / 42

Let's proceed to step 4:
54 divided by 42 is 1 with a remainder of 12.
Record the quotient 1 as the next digit in the result. 
Result so far: 231.0
If we take 42 away from 54, we end up with 12.
Include the next digit (3) from the dividend after 12, then repeat: 123 / 42

Advancing to step 5:
123 divided by 42 is 2 with a remainder of 39.
Put 2 as the next digit of the answer. 
Result so far: 2312.0
Subtract 84 from 123 to get 39.
Fetch the next digit (5) from the dividend, attach it to 39 and continue: 395 / 42

Step 6:
The number 42 fits into 395 9 times, leaving a remainder of 17.
The number 9 becomes the next digit in our result. 
Result so far: 23129.0
If we take 378 away from 395, 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.

Advancing to step 7:
42 can be fit into 170 4 times, resulting in a remainder of 2.
Put 4 as the next digit of the answer. 
Result so far: 23129.4
If we take 168 away from 170, we end up with 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 8:
42 can be fit into 20 0 times, resulting in a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 23129.4
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.

Let's proceed to step 9:
If we divide 200 by 42, we get 4 and a remainder of 32.
Put 4 as the next digit of the answer. 
Result so far: 23129.404
Deduct 168 from 200 and we're left 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.

Step 10:
The number 42 fits into 320 7 times, leaving a remainder of 26.
Write down 7 as next digit of the result. 
Result so far: 23129.4047
Subtract 294 from 320 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Step 11:
When dividing 260 by 42, we get 6 with a remainder of 8.
Record the quotient 6 as the next digit in the result. 
Result so far: 23129.40476
If we take 252 away from 260, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 12:
If we divide 80 by 42, we get 1 and a remainder of 38.
Record the quotient 1 as the next digit in the result. 
Result so far: 23129.404761
The remainder is 38 after subtracting 42 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

On to step 13:
42 can be fit into 380 9 times, resulting in a remainder of 2.
Write down 9 as next digit of the result. 
Result so far: 23129.4047619
The remainder is 2 after subtracting 378 from 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 14:
The number 42 fits into 20 0 times, leaving a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 23129.4047619
If we take 0 away from 20, we end up 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.

After the division, we end up with 23129.4047619 and a remainder of 2e-08.
