753055 ÷ 42 
The aim is to understand the frequency of 42 in 753055.

On to step 1:
The number 42 fits into 7 0 times, leaving a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Append the next digit (5) from the dividend to 7 and continue with: 75 / 42

Let's proceed to step 2:
When dividing 75 by 42, we get 1 with a remainder of 33.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 42 from 75 and we're left with 33.
Append the next digit (3) from the dividend to 33 and continue with: 333 / 42

Step 3:
333 divided by 42 is 7 with a remainder of 39.
The number 7 becomes the next digit in our result. 
Result so far: 17.0
The remainder is 39 after subtracting 294 from 333.
Grab the next digit (0) from the dividend, add it to 39, then carry on: 390 / 42

Advancing to step 4:
390 divided by 42 is 9 with a remainder of 12.
The number 9 becomes the next digit in our result. 
Result so far: 179.0
Subtracting 378 from 390 leaves us with 12.
Append the next digit (5) from the dividend to 12 and continue with: 125 / 42

On to step 5:
125 divided by 42 is 2 with a remainder of 41.
Use 2 as the next digit of our solution. 
Result so far: 1792.0
The remainder is 41 after subtracting 84 from 125.
Append the next digit (5) from the dividend to 41 and continue with: 415 / 42

Going ahead to step 6:
The number 42 fits into 415 9 times, leaving a remainder of 37.
Put 9 as the next digit of the answer. 
Result so far: 17929.0
Subtracting 378 from 415 leaves us with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

On to step 7:
The number 42 fits into 370 8 times, leaving a remainder of 34.
Write down 8 as next digit of the result. 
Result so far: 17929.8
Subtracting 336 from 370 leaves us 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.

Step 8:
If we divide 340 by 42, we get 8 and a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 17929.88
The remainder is 4 after subtracting 336 from 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

In conclusion, the division gives 17929.88 with a balance of 0.004.
