We're dividing 783656 by 42 
The aim is to understand the frequency of 42 in 783656.

Advancing to step 1:
42 goes into 7 0 times with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Bring next digit (8) of the dividend behind the 7 and repeat the process: 78 / 42

Moving on to step 2:
When dividing 78 by 42, we get 1 with a remainder of 36.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 42 away from 78, we end up with 36.
Bring next digit (3) of the dividend behind the 36 and repeat the process: 363 / 42

On to step 3:
42 can be fit into 363 8 times, resulting in a remainder of 27.
Write down 8 as next digit of the result. 
Result so far: 18.0
Subtract 336 from 363 to get 27.
Grab the next digit (6) from the dividend, add it to 27, then carry on: 276 / 42

Going ahead to step 4:
When dividing 276 by 42, we get 6 with a remainder of 24.
Put 6 as the next digit of the answer. 
Result so far: 186.0
The remainder is 24 after subtracting 252 from 276.
Bring next digit (5) of the dividend behind the 24 and repeat the process: 245 / 42

Step 5:
If we divide 245 by 42, we get 5 and a remainder of 35.
Use 5 as the next digit of our solution. 
Result so far: 1865.0
The remainder is 35 after subtracting 210 from 245.
Fetch the next digit (6) from the dividend, attach it to 35 and continue: 356 / 42

Advancing to step 6:
The number 42 fits into 356 8 times, leaving a remainder of 20.
Use 8 as the next digit of our solution. 
Result so far: 18658.0
Deduct 336 from 356 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 7:
42 can be fit into 200 4 times, resulting in a remainder of 32.
Write down 4 as next digit of the result. 
Result so far: 18658.4
Subtract 168 from 200 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Let's proceed to step 8:
320 divided by 42 is 7 with a remainder of 26.
The number 7 becomes the next digit in our result. 
Result so far: 18658.47
If we subtract 294 from 320, we 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.

Moving on to step 9:
42 goes into 260 6 times with a remainder of 8.
The number 6 becomes the next digit in our result. 
Result so far: 18658.476
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.

Advancing to step 10:
80 divided by 42 is 1 with a remainder of 38.
The next digit of our result is 1. 
Result so far: 18658.4761
Subtracting 42 from 80 leaves us 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.

Going ahead to step 11:
The number 42 fits into 380 9 times, leaving a remainder of 2.
The number 9 becomes the next digit in our result. 
Result so far: 18658.47619
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.

Going ahead to step 12:
The number 42 fits into 20 0 times, leaving a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 18658.47619
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.

Moving on to step 13:
42 goes into 200 4 times with a remainder of 32.
Use 4 as the next digit of our solution. 
Result so far: 18658.4761904
Subtract 168 from 200 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 14:
42 can be fit into 320 7 times, resulting in a remainder of 26.
The number 7 becomes the next digit in our result. 
Result so far: 18658.47619047
If we subtract 294 from 320, we 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.

After the division, we end up with 18658.47619047 and a remainder of 2.6e-08.
