We divide 571613 by 42
The aim is to understand the frequency of 42 in 571613.

Step 1:
When dividing 5 by 42, we get 0 with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Take the next digit (7) from the dividend and append it to 5, then repeat: 57 / 42

On to step 2:
42 goes into 57 1 times with a remainder of 15.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 42 from 57 to get 15.
Append the next digit (1) from the dividend to 15 and continue with: 151 / 42

Going ahead to step 3:
When dividing 151 by 42, we get 3 with a remainder of 25.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
Deduct 126 from 151 and we're left with 25.
Grab the next digit (6) from the dividend, add it to 25, then carry on: 256 / 42

Step 4:
If we divide 256 by 42, we get 6 and a remainder of 4.
Put 6 as the next digit of the answer. 
Result so far: 136.0
The remainder is 4 after subtracting 252 from 256.
Take the next digit (1) from the dividend and append it to 4, then repeat: 41 / 42

Moving on to step 5:
If we divide 41 by 42, we get 0 and a remainder of 41.
The next digit of our result is 0. 
Result so far: 1360.0
Deduct 0 from 41 and we're left with 41.
Take the next digit (3) from the dividend and append it to 41, then repeat: 413 / 42

On to step 6:
The number 42 fits into 413 9 times, leaving a remainder of 35.
Put 9 as the next digit of the answer. 
Result so far: 13609.0
If we subtract 378 from 413, we get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

On to step 7:
When dividing 350 by 42, we get 8 with a remainder of 14.
The next digit of our result is 8. 
Result so far: 13609.8
The remainder is 14 after subtracting 336 from 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 8:
If we divide 140 by 42, we get 3 and a remainder of 14.
Use 3 as the next digit of our solution. 
Result so far: 13609.83
Subtracting 126 from 140 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 9:
42 goes into 140 3 times with a remainder of 14.
Write down 3 as next digit of the result. 
Result so far: 13609.833
Deduct 126 from 140 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

In conclusion, the division gives 13609.833 with a balance of 0.0014.
