726772 ÷ 42 
The aim is to understand the frequency of 42 in 726772.

Step 1:
42 can be fit into 7 0 times, resulting in a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Fetch the next digit (2) from the dividend, attach it to 7 and continue: 72 / 42

Going ahead to step 2:
42 can be fit into 72 1 times, resulting in a remainder of 30.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 42 from 72 to get 30.
Fetch the next digit (6) from the dividend, attach it to 30 and continue: 306 / 42

Going ahead to step 3:
306 divided by 42 is 7 with a remainder of 12.
Write down 7 as next digit of the result. 
Result so far: 17.0
If we subtract 294 from 306, we get 12.
Take the next digit (7) from the dividend and append it to 12, then repeat: 127 / 42

Step 4:
The number 42 fits into 127 3 times, leaving a remainder of 1.
Write down 3 as next digit of the result. 
Result so far: 173.0
The remainder is 1 after subtracting 126 from 127.
Take the next digit (7) from the dividend and append it to 1, then repeat: 17 / 42

Moving on to step 5:
The number 42 fits into 17 0 times, leaving a remainder of 17.
Put 0 as the next digit of the answer. 
Result so far: 1730.0
Subtracting 0 from 17 leaves us with 17.
Take the next digit (2) from the dividend and append it to 17, then repeat: 172 / 42

Advancing to step 6:
42 can be fit into 172 4 times, resulting in a remainder of 4.
Use 4 as the next digit of our solution. 
Result so far: 17304.0
If we subtract 168 from 172, we 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.

Going ahead to step 7:
If we divide 40 by 42, we get 0 and a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 17304.0
Deduct 0 from 40 and we're left 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 8:
If we divide 400 by 42, we get 9 and a remainder of 22.
The number 9 becomes the next digit in our result. 
Result so far: 17304.09
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.

Let's proceed to step 9:
42 goes into 220 5 times with a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 17304.095
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.

Moving on to step 10:
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: 17304.0952
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.

Moving on to step 11:
42 goes into 160 3 times with a remainder of 34.
Put 3 as the next digit of the answer. 
Result so far: 17304.09523
Subtract 126 from 160 to 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 12:
42 can be fit into 340 8 times, resulting in a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 17304.095238
Subtracting 336 from 340 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 13:
The number 42 fits into 40 0 times, leaving a remainder of 40.
The next digit of our result is 0. 
Result so far: 17304.095238
If we subtract 0 from 40, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 14:
The number 42 fits into 400 9 times, leaving a remainder of 22.
Use 9 as the next digit of our solution. 
Result so far: 17304.09523809
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.

After the division, we end up with 17304.09523809 and a remainder of 2.2e-08.
