342235 ÷ 57 
The aim is to understand the frequency of 57 in 342235.

On to step 1:
3 divided by 57 is 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Grab the next digit (4) from the dividend, add it to 3, then carry on: 34 / 57

On to step 2:
34 divided by 57 is 0 with a remainder of 34.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 34 to get 34.
Fetch the next digit (2) from the dividend, attach it to 34 and continue: 342 / 57

On to step 3:
The number 57 fits into 342 6 times, leaving a remainder of 0.
Use 6 as the next digit of our solution. 
Result so far: 6.0
Deduct 342 from 342 and we're left with 0.
Take the next digit (2) from the dividend and append it to 0, then repeat: 2 / 57

Moving on to step 4:
When dividing 2 by 57, we get 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 60.0
Subtract 0 from 2 to get 2.
Fetch the next digit (3) from the dividend, attach it to 2 and continue: 23 / 57

On to step 5:
23 divided by 57 is 0 with a remainder of 23.
The number 0 becomes the next digit in our result. 
Result so far: 600.0
The remainder is 23 after subtracting 0 from 23.
Fetch the next digit (5) from the dividend, attach it to 23 and continue: 235 / 57

On to step 6:
57 can be fit into 235 4 times, resulting in a remainder of 7.
Use 4 as the next digit of our solution. 
Result so far: 6004.0
If we take 228 away from 235, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 7:
57 goes into 70 1 times with a remainder of 13.
The next digit of our result is 1. 
Result so far: 6004.1
Subtracting 57 from 70 leaves us with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Advancing to step 8:
130 divided by 57 is 2 with a remainder of 16.
Write down 2 as next digit of the result. 
Result so far: 6004.12
Subtract 114 from 130 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 9:
When dividing 160 by 57, we get 2 with a remainder of 46.
Write down 2 as next digit of the result. 
Result so far: 6004.122
Subtracting 114 from 160 leaves us with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Our division results in 6004.122 with a remaining 0.0046.
