967639 ÷ 57 
The aim is to understand the frequency of 57 in 967639.

Step 1:
57 goes into 9 0 times with a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Append the next digit (6) from the dividend to 9 and continue with: 96 / 57

On to step 2:
57 goes into 96 1 times with a remainder of 39.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 57 from 96 to get 39.
Append the next digit (7) from the dividend to 39 and continue with: 397 / 57

Moving on to step 3:
57 goes into 397 6 times with a remainder of 55.
The number 6 becomes the next digit in our result. 
Result so far: 16.0
Subtract 342 from 397 to get 55.
Fetch the next digit (6) from the dividend, attach it to 55 and continue: 556 / 57

Let's proceed to step 4:
When dividing 556 by 57, we get 9 with a remainder of 43.
The next digit of our result is 9. 
Result so far: 169.0
The remainder is 43 after subtracting 513 from 556.
Append the next digit (3) from the dividend to 43 and continue with: 433 / 57

Going ahead to step 5:
When dividing 433 by 57, we get 7 with a remainder of 34.
The number 7 becomes the next digit in our result. 
Result so far: 1697.0
Subtracting 399 from 433 leaves us with 34.
Append the next digit (9) from the dividend to 34 and continue with: 349 / 57

Step 6:
57 can be fit into 349 6 times, resulting in a remainder of 7.
Record the quotient 6 as the next digit in the result. 
Result so far: 16976.0
Subtracting 342 from 349 leaves us 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 can be fit into 70 1 times, resulting in a remainder of 13.
Put 1 as the next digit of the answer. 
Result so far: 16976.1
Subtract 57 from 70 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Moving on to step 8:
When dividing 130 by 57, we get 2 with a remainder of 16.
The next digit of our result is 2. 
Result so far: 16976.12
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.

Moving on to step 9:
When dividing 160 by 57, we get 2 with a remainder of 46.
Record the quotient 2 as the next digit in the result. 
Result so far: 16976.122
If we subtract 114 from 160, we get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

The final outcome is 16976.122, with a leftover of 0.0046.
