129299 divided by 42 
The aim is to understand the frequency of 42 in 129299.

Let's proceed to step 1:
42 goes into 1 0 times with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 42

Going ahead to step 2:
42 goes into 12 0 times with a remainder of 12.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 12 leaves us with 12.
Append the next digit (9) from the dividend to 12 and continue with: 129 / 42

On to step 3:
129 divided by 42 is 3 with a remainder of 3.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we take 126 away from 129, we end up with 3.
Take the next digit (2) from the dividend and append it to 3, then repeat: 32 / 42

Going ahead to step 4:
42 goes into 32 0 times with a remainder of 32.
Write down 0 as next digit of the result. 
Result so far: 30.0
If we take 0 away from 32, we end up with 32.
Include the next digit (9) from the dividend after 32, then repeat: 329 / 42

Going ahead to step 5:
42 goes into 329 7 times with a remainder of 35.
Record the quotient 7 as the next digit in the result. 
Result so far: 307.0
Deduct 294 from 329 and we're left with 35.
Grab the next digit (9) from the dividend, add it to 35, then carry on: 359 / 42

Moving on to step 6:
When dividing 359 by 42, we get 8 with a remainder of 23.
Write down 8 as next digit of the result. 
Result so far: 3078.0
If we subtract 336 from 359, we get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Moving on to step 7:
When dividing 230 by 42, we get 5 with a remainder of 20.
Write down 5 as next digit of the result. 
Result so far: 3078.5
If we take 210 away from 230, 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.

Step 8:
The number 42 fits into 200 4 times, leaving a remainder of 32.
The next digit of our result is 4. 
Result so far: 3078.54
Subtracting 168 from 200 leaves us 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 9:
When dividing 320 by 42, we get 7 with a remainder of 26.
Record the quotient 7 as the next digit in the result. 
Result so far: 3078.547
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.

Going ahead to step 10:
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: 3078.5476
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 11:
When dividing 80 by 42, we get 1 with a remainder of 38.
Record the quotient 1 as the next digit in the result. 
Result so far: 3078.54761
Deduct 42 from 80 and we're left 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 12:
If we divide 380 by 42, we get 9 and a remainder of 2.
Write down 9 as next digit of the result. 
Result so far: 3078.547619
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.

Let's proceed to step 13:
42 goes into 20 0 times with a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 3078.547619
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.

Let's proceed to step 14:
200 divided by 42 is 4 with a remainder of 32.
The next digit of our result is 4. 
Result so far: 3078.54761904
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.

The final result is 3078.54761904 with a remainder of 3.2e-08.
