513472 divided by 57 
The aim is to understand the frequency of 57 in 513472.

Moving on to step 1:
57 can be fit into 5 0 times, resulting in a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Include the next digit (1) from the dividend after 5, then repeat: 51 / 57

Moving on to step 2:
If we divide 51 by 57, we get 0 and a remainder of 51.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 51 and we're left with 51.
Bring next digit (3) of the dividend behind the 51 and repeat the process: 513 / 57

Let's proceed to step 3:
57 goes into 513 9 times with a remainder of 0.
The next digit of our result is 9. 
Result so far: 9.0
If we subtract 513 from 513, we get 0.
Append the next digit (4) from the dividend to 0 and continue with: 4 / 57

Step 4:
The number 57 fits into 4 0 times, leaving a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 90.0
If we subtract 0 from 4, we get 4.
Bring next digit (7) of the dividend behind the 4 and repeat the process: 47 / 57

Moving on to step 5:
47 divided by 57 is 0 with a remainder of 47.
Use 0 as the next digit of our solution. 
Result so far: 900.0
The remainder is 47 after subtracting 0 from 47.
Append the next digit (2) from the dividend to 47 and continue with: 472 / 57

Moving on to step 6:
The number 57 fits into 472 8 times, leaving a remainder of 16.
Record the quotient 8 as the next digit in the result. 
Result so far: 9008.0
If we take 456 away from 472, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 7:
The number 57 fits into 160 2 times, leaving a remainder of 46.
Record the quotient 2 as the next digit in the result. 
Result so far: 9008.2
Subtract 114 from 160 to 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.

Advancing to step 8:
57 goes into 460 8 times with a remainder of 4.
The next digit of our result is 8. 
Result so far: 9008.28
If we subtract 456 from 460, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 9:
When dividing 40 by 57, we get 0 with a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 9008.28
If we subtract 0 from 40, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 10:
When dividing 400 by 57, we get 7 with a remainder of 1.
Use 7 as the next digit of our solution. 
Result so far: 9008.2807
If we take 399 away from 400, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 11:
If we divide 10 by 57, we get 0 and a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 9008.2807
If we subtract 0 from 10, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 12:
57 goes into 100 1 times with a remainder of 43.
Put 1 as the next digit of the answer. 
Result so far: 9008.280701
Subtract 57 from 100 to get 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Let's proceed to step 13:
57 can be fit into 430 7 times, resulting in a remainder of 31.
Record the quotient 7 as the next digit in the result. 
Result so far: 9008.2807017
If we subtract 399 from 430, we get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Moving on to step 14:
57 can be fit into 310 5 times, resulting in a remainder of 25.
The next digit of our result is 5. 
Result so far: 9008.28070175
Subtract 285 from 310 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

The final outcome is 9008.28070175, with a leftover of 2.5e-08.
