We divide 756420 by 42
The aim is to understand the frequency of 42 in 756420.

Let's proceed to step 1:
If we divide 7 by 42, we get 0 and a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Grab the next digit (5) from the dividend, add it to 7, then carry on: 75 / 42

Step 2:
If we divide 75 by 42, we get 1 and a remainder of 33.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 42 away from 75, we end up with 33.
Include the next digit (6) from the dividend after 33, then repeat: 336 / 42

Advancing to step 3:
42 goes into 336 8 times with a remainder of 0.
The number 8 becomes the next digit in our result. 
Result so far: 18.0
Subtract 336 from 336 to get 0.
Fetch the next digit (4) from the dividend, attach it to 0 and continue: 4 / 42

On to step 4:
42 can be fit into 4 0 times, resulting in a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 180.0
If we subtract 0 from 4, we get 4.
Fetch the next digit (2) from the dividend, attach it to 4 and continue: 42 / 42

Advancing to step 5:
The number 42 fits into 42 1 times, leaving a remainder of 0.
Put 1 as the next digit of the answer. 
Result so far: 1801.0
Deduct 42 from 42 and we're left with 0.
Include the next digit (0) from the dividend after 0, then repeat: 0 / 42

Going ahead to step 6:
42 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 18010.0
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 7:
42 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 18010.0
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 8:
When dividing 0 by 42, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 18010.0
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

In conclusion, the division gives 18010.0 with a balance of 0.0.
