We're dividing 455568 by 57 
The aim is to understand the frequency of 57 in 455568.

Step 1:
4 divided by 57 is 0 with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Fetch the next digit (5) from the dividend, attach it to 4 and continue: 45 / 57

Moving on to step 2:
57 goes into 45 0 times with a remainder of 45.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 45 to get 45.
Fetch the next digit (5) from the dividend, attach it to 45 and continue: 455 / 57

On to step 3:
When dividing 455 by 57, we get 7 with a remainder of 56.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
The remainder is 56 after subtracting 399 from 455.
Include the next digit (5) from the dividend after 56, then repeat: 565 / 57

Advancing to step 4:
565 divided by 57 is 9 with a remainder of 52.
Put 9 as the next digit of the answer. 
Result so far: 79.0
Deduct 513 from 565 and we're left with 52.
Bring next digit (6) of the dividend behind the 52 and repeat the process: 526 / 57

Advancing to step 5:
57 goes into 526 9 times with a remainder of 13.
Record the quotient 9 as the next digit in the result. 
Result so far: 799.0
If we subtract 513 from 526, we get 13.
Take the next digit (8) from the dividend and append it to 13, then repeat: 138 / 57

Moving on to step 6:
The number 57 fits into 138 2 times, leaving a remainder of 24.
Record the quotient 2 as the next digit in the result. 
Result so far: 7992.0
If we subtract 114 from 138, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 7:
240 divided by 57 is 4 with a remainder of 12.
The number 4 becomes the next digit in our result. 
Result so far: 7992.4
Subtract 228 from 240 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 8:
When dividing 120 by 57, we get 2 with a remainder of 6.
Record the quotient 2 as the next digit in the result. 
Result so far: 7992.42
If we take 114 away from 120, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 9:
The number 57 fits into 60 1 times, leaving a remainder of 3.
The number 1 becomes the next digit in our result. 
Result so far: 7992.421
If we take 57 away from 60, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 10:
57 can be fit into 30 0 times, resulting in a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 7992.421
If we take 0 away from 30, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 11:
57 can be fit into 300 5 times, resulting in a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 7992.42105
Deduct 285 from 300 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 12:
150 divided by 57 is 2 with a remainder of 36.
Record the quotient 2 as the next digit in the result. 
Result so far: 7992.421052
The remainder is 36 after subtracting 114 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

On to step 13:
If we divide 360 by 57, we get 6 and a remainder of 18.
Use 6 as the next digit of our solution. 
Result so far: 7992.4210526
The remainder is 18 after subtracting 342 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 14:
57 can be fit into 180 3 times, resulting in a remainder of 9.
Record the quotient 3 as the next digit in the result. 
Result so far: 7992.42105263
If we take 171 away from 180, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

The quotient of the division is 7992.42105263, and the remainder is 9e-09.
