391481 ÷ 57 
The aim is to understand the frequency of 57 in 391481.

Let's proceed to step 1:
57 can be fit into 3 0 times, resulting in 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.
Bring next digit (9) of the dividend behind the 3 and repeat the process: 39 / 57

Going ahead to step 2:
39 divided by 57 is 0 with a remainder of 39.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 39 leaves us with 39.
Fetch the next digit (1) from the dividend, attach it to 39 and continue: 391 / 57

On to step 3:
When dividing 391 by 57, we get 6 with a remainder of 49.
Use 6 as the next digit of our solution. 
Result so far: 6.0
Subtracting 342 from 391 leaves us with 49.
Grab the next digit (4) from the dividend, add it to 49, then carry on: 494 / 57

Moving on to step 4:
57 can be fit into 494 8 times, resulting in a remainder of 38.
Put 8 as the next digit of the answer. 
Result so far: 68.0
Deduct 456 from 494 and we're left with 38.
Append the next digit (8) from the dividend to 38 and continue with: 388 / 57

Let's proceed to step 5:
57 can be fit into 388 6 times, resulting in a remainder of 46.
Put 6 as the next digit of the answer. 
Result so far: 686.0
If we subtract 342 from 388, we get 46.
Include the next digit (1) from the dividend after 46, then repeat: 461 / 57

Advancing to step 6:
57 can be fit into 461 8 times, resulting in a remainder of 5.
Write down 8 as next digit of the result. 
Result so far: 6868.0
If we take 456 away from 461, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 7:
The number 57 fits into 50 0 times, leaving a remainder of 50.
The number 0 becomes the next digit in our result. 
Result so far: 6868.0
The remainder is 50 after subtracting 0 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 8:
The number 57 fits into 500 8 times, leaving a remainder of 44.
The number 8 becomes the next digit in our result. 
Result so far: 6868.08
Deduct 456 from 500 and we're left with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Moving on to step 9:
If we divide 440 by 57, we get 7 and a remainder of 41.
Put 7 as the next digit of the answer. 
Result so far: 6868.087
Deduct 399 from 440 and we're left with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Let's proceed to step 10:
The number 57 fits into 410 7 times, leaving a remainder of 11.
Use 7 as the next digit of our solution. 
Result so far: 6868.0877
Subtracting 399 from 410 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

In conclusion, the division gives 6868.0877 with a balance of 0.00011.
