The aim is to understand the frequency of 42 in 72708982.

Moving on to step 1:
42 goes into 7 0 times with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Grab the next digit (2) from the dividend, add it to 7, then carry on: 72 / 42

Advancing to step 2:
72 divided by 42 is 1 with a remainder of 30.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 42 from 72 and we're left with 30.
Grab the next digit (7) from the dividend, add it to 30, then carry on: 307 / 42

On to step 3:
If we divide 307 by 42, we get 7 and a remainder of 13.
The number 7 becomes the next digit in our result. 
Result so far: 17.0
Subtracting 294 from 307 leaves us with 13.
Fetch the next digit (0) from the dividend, attach it to 13 and continue: 130 / 42

On to step 4:
If we divide 130 by 42, we get 3 and a remainder of 4.
The next digit of our result is 3. 
Result so far: 173.0
If we take 126 away from 130, we end up with 4.
Append the next digit (8) from the dividend to 4 and continue with: 48 / 42

Advancing to step 5:
48 divided by 42 is 1 with a remainder of 6.
Write down 1 as next digit of the result. 
Result so far: 1731.0
Deduct 42 from 48 and we're left with 6.
Include the next digit (9) from the dividend after 6, then repeat: 69 / 42

Advancing to step 6:
If we divide 69 by 42, we get 1 and a remainder of 27.
Use 1 as the next digit of our solution. 
Result so far: 17311.0
If we take 42 away from 69, we end up with 27.
Include the next digit (8) from the dividend after 27, then repeat: 278 / 42

On to step 7:
42 goes into 278 6 times with a remainder of 26.
The number 6 becomes the next digit in our result. 
Result so far: 173116.0
Subtract 252 from 278 to get 26.
Include the next digit (2) from the dividend after 26, then repeat: 262 / 42

Moving on to step 8:
262 divided by 42 is 6 with a remainder of 10.
The number 6 becomes the next digit in our result. 
Result so far: 1731166.0
The remainder is 10 after subtracting 252 from 262.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 9:
42 goes into 100 2 times with a remainder of 16.
Use 2 as the next digit of our solution. 
Result so far: 1731166.2
The remainder is 16 after subtracting 84 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 10:
The number 42 fits into 160 3 times, leaving a remainder of 34.
Write down 3 as next digit of the result. 
Result so far: 1731166.23
If we subtract 126 from 160, we get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Going ahead to step 11:
42 goes into 340 8 times with a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 1731166.238
Subtract 336 from 340 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 12:
42 goes into 40 0 times with a remainder of 40.
The next digit of our result is 0. 
Result so far: 1731166.238
Subtracting 0 from 40 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 13:
If we divide 400 by 42, we get 9 and a remainder of 22.
Put 9 as the next digit of the answer. 
Result so far: 1731166.23809
The remainder is 22 after subtracting 378 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 14:
220 divided by 42 is 5 with a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 1731166.238095
Deduct 210 from 220 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 15:
100 divided by 42 is 2 with a remainder of 16.
Record the quotient 2 as the next digit in the result. 
Result so far: 1731166.2380952
The remainder is 16 after subtracting 84 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 16:
42 can be fit into 160 3 times, resulting in a remainder of 34.
Record the quotient 3 as the next digit in the result. 
Result so far: 1731166.23809523
Deduct 126 from 160 and we're left with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

The final result is 1731166.23809523 with a remainder of 3.4e-08.
