We're dividing 869432 by 42 
The aim is to understand the frequency of 42 in 869432.

Let's proceed to step 1:
The number 42 fits into 8 0 times, leaving a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Include the next digit (6) from the dividend after 8, then repeat: 86 / 42

Going ahead to step 2:
When dividing 86 by 42, we get 2 with a remainder of 2.
Use 2 as the next digit of our solution. 
Result so far: 2.0
The remainder is 2 after subtracting 84 from 86.
Include the next digit (9) from the dividend after 2, then repeat: 29 / 42

Let's proceed to step 3:
The number 42 fits into 29 0 times, leaving a remainder of 29.
Use 0 as the next digit of our solution. 
Result so far: 20.0
Subtract 0 from 29 to get 29.
Take the next digit (4) from the dividend and append it to 29, then repeat: 294 / 42

Let's proceed to step 4:
42 goes into 294 7 times with a remainder of 0.
Record the quotient 7 as the next digit in the result. 
Result so far: 207.0
Subtracting 294 from 294 leaves us with 0.
Include the next digit (3) from the dividend after 0, then repeat: 3 / 42

Step 5:
When dividing 3 by 42, we get 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 2070.0
Deduct 0 from 3 and we're left with 3.
Fetch the next digit (2) from the dividend, attach it to 3 and continue: 32 / 42

Let's proceed to step 6:
The number 42 fits into 32 0 times, leaving a remainder of 32.
Use 0 as the next digit of our solution. 
Result so far: 20700.0
If we take 0 away from 32, 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.

On to step 7:
If we divide 320 by 42, we get 7 and a remainder of 26.
Record the quotient 7 as the next digit in the result. 
Result so far: 20700.7
If we take 294 away from 320, we end up 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.

Advancing to step 8:
42 can be fit into 260 6 times, resulting in a remainder of 8.
The number 6 becomes the next digit in our result. 
Result so far: 20700.76
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.

Step 9:
When dividing 80 by 42, we get 1 with a remainder of 38.
The next digit of our result is 1. 
Result so far: 20700.761
If we take 42 away from 80, we end up with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Let's proceed to step 10:
380 divided by 42 is 9 with a remainder of 2.
Write down 9 as next digit of the result. 
Result so far: 20700.7619
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.

Moving on to step 11:
If we divide 20 by 42, we get 0 and a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 20700.7619
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.

Let's proceed to step 12:
42 goes into 200 4 times with a remainder of 32.
The number 4 becomes the next digit in our result. 
Result so far: 20700.761904
The remainder is 32 after subtracting 168 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 13:
When dividing 320 by 42, we get 7 with a remainder of 26.
Write down 7 as next digit of the result. 
Result so far: 20700.7619047
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.

Going ahead to step 14:
The number 42 fits into 260 6 times, leaving a remainder of 8.
Write down 6 as next digit of the result. 
Result so far: 20700.76190476
Deduct 252 from 260 and we're left 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.

Our division results in 20700.76190476 with a remaining 8e-09.
