We look at the division of 959151 by 42 
The aim is to understand the frequency of 42 in 959151.

Step 1:
42 goes into 9 0 times with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Include the next digit (5) from the dividend after 9, then repeat: 95 / 42

Step 2:
42 goes into 95 2 times with a remainder of 11.
The next digit of our result is 2. 
Result so far: 2.0
Subtracting 84 from 95 leaves us with 11.
Take the next digit (9) from the dividend and append it to 11, then repeat: 119 / 42

Step 3:
42 can be fit into 119 2 times, resulting in a remainder of 35.
The next digit of our result is 2. 
Result so far: 22.0
Subtracting 84 from 119 leaves us with 35.
Grab the next digit (1) from the dividend, add it to 35, then carry on: 351 / 42

Let's proceed to step 4:
351 divided by 42 is 8 with a remainder of 15.
Use 8 as the next digit of our solution. 
Result so far: 228.0
If we subtract 336 from 351, we get 15.
Include the next digit (5) from the dividend after 15, then repeat: 155 / 42

Let's proceed to step 5:
155 divided by 42 is 3 with a remainder of 29.
The next digit of our result is 3. 
Result so far: 2283.0
If we take 126 away from 155, we end up with 29.
Include the next digit (1) from the dividend after 29, then repeat: 291 / 42

Going ahead to step 6:
The number 42 fits into 291 6 times, leaving a remainder of 39.
Put 6 as the next digit of the answer. 
Result so far: 22836.0
If we subtract 252 from 291, we get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Advancing to step 7:
42 goes into 390 9 times with a remainder of 12.
Use 9 as the next digit of our solution. 
Result so far: 22836.9
The remainder is 12 after subtracting 378 from 390.
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 8:
The number 42 fits into 120 2 times, leaving a remainder of 36.
The next digit of our result is 2. 
Result so far: 22836.92
Subtract 84 from 120 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

On to step 9:
When dividing 360 by 42, we get 8 with a remainder of 24.
Put 8 as the next digit of the answer. 
Result so far: 22836.928
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.

Moving on to step 10:
42 goes into 240 5 times with a remainder of 30.
Write down 5 as next digit of the result. 
Result so far: 22836.9285
Deduct 210 from 240 and we're left 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 11:
The number 42 fits into 300 7 times, leaving a remainder of 6.
Write down 7 as next digit of the result. 
Result so far: 22836.92857
Subtract 294 from 300 to 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.

Moving on to step 12:
42 goes into 60 1 times with a remainder of 18.
The next digit of our result is 1. 
Result so far: 22836.928571
Deduct 42 from 60 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 13:
If we divide 180 by 42, we get 4 and a remainder of 12.
Record the quotient 4 as the next digit in the result. 
Result so far: 22836.9285714
Subtracting 168 from 180 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 14:
The number 42 fits into 120 2 times, leaving a remainder of 36.
Write down 2 as next digit of the result. 
Result so far: 22836.92857142
Subtract 84 from 120 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

After the division, we end up with 22836.92857142 and a remainder of 3.6e-08.
