354882 ÷ 57 
The aim is to understand the frequency of 57 in 354882.

On to step 1:
The number 57 fits into 3 0 times, leaving a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Take the next digit (5) from the dividend and append it to 3, then repeat: 35 / 57

Moving on to step 2:
When dividing 35 by 57, we get 0 with a remainder of 35.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 35 after subtracting 0 from 35.
Bring next digit (4) of the dividend behind the 35 and repeat the process: 354 / 57

On to step 3:
57 can be fit into 354 6 times, resulting in a remainder of 12.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
Subtracting 342 from 354 leaves us with 12.
Fetch the next digit (8) from the dividend, attach it to 12 and continue: 128 / 57

Let's proceed to step 4:
57 goes into 128 2 times with a remainder of 14.
Put 2 as the next digit of the answer. 
Result so far: 62.0
Subtract 114 from 128 to get 14.
Take the next digit (8) from the dividend and append it to 14, then repeat: 148 / 57

On to step 5:
57 can be fit into 148 2 times, resulting in a remainder of 34.
The next digit of our result is 2. 
Result so far: 622.0
If we subtract 114 from 148, we get 34.
Take the next digit (2) from the dividend and append it to 34, then repeat: 342 / 57

Step 6:
When dividing 342 by 57, we get 6 with a remainder of 0.
Use 6 as the next digit of our solution. 
Result so far: 6226.0
Subtract 342 from 342 to 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.

Advancing to step 7:
57 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 6226.0
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.

Going ahead to step 8:
57 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 6226.0
If we take 0 away from 0, we end up 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.

The final outcome is 6226.0, with a leftover of 0.0.
