We look at the division of 175811 by 57 
The aim is to understand the frequency of 57 in 175811.

Advancing to step 1:
57 goes into 1 0 times with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Fetch the next digit (7) from the dividend, attach it to 1 and continue: 17 / 57

Advancing to step 2:
17 divided by 57 is 0 with a remainder of 17.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 17 leaves us with 17.
Take the next digit (5) from the dividend and append it to 17, then repeat: 175 / 57

On to step 3:
57 goes into 175 3 times with a remainder of 4.
The next digit of our result is 3. 
Result so far: 3.0
If we subtract 171 from 175, we get 4.
Bring next digit (8) of the dividend behind the 4 and repeat the process: 48 / 57

Step 4:
When dividing 48 by 57, we get 0 with a remainder of 48.
The number 0 becomes the next digit in our result. 
Result so far: 30.0
If we subtract 0 from 48, we get 48.
Bring next digit (1) of the dividend behind the 48 and repeat the process: 481 / 57

On to step 5:
481 divided by 57 is 8 with a remainder of 25.
Record the quotient 8 as the next digit in the result. 
Result so far: 308.0
Deduct 456 from 481 and we're left with 25.
Grab the next digit (1) from the dividend, add it to 25, then carry on: 251 / 57

Advancing to step 6:
251 divided by 57 is 4 with a remainder of 23.
Put 4 as the next digit of the answer. 
Result so far: 3084.0
If we subtract 228 from 251, we get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Let's proceed to step 7:
The number 57 fits into 230 4 times, leaving a remainder of 2.
Use 4 as the next digit of our solution. 
Result so far: 3084.4
Subtracting 228 from 230 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 8:
57 can be fit into 20 0 times, resulting in a remainder of 20.
The next digit of our result is 0. 
Result so far: 3084.4
Subtracting 0 from 20 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 9:
If we divide 200 by 57, we get 3 and a remainder of 29.
The next digit of our result is 3. 
Result so far: 3084.403
If we subtract 171 from 200, we get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

On to step 10:
When dividing 290 by 57, we get 5 with a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 3084.4035
The remainder is 5 after subtracting 285 from 290.
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 11:
50 divided by 57 is 0 with a remainder of 50.
Write down 0 as next digit of the result. 
Result so far: 3084.4035
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.

Step 12:
The number 57 fits into 500 8 times, leaving a remainder of 44.
Put 8 as the next digit of the answer. 
Result so far: 3084.403508
Subtract 456 from 500 to get 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 13:
The number 57 fits into 440 7 times, leaving a remainder of 41.
Use 7 as the next digit of our solution. 
Result so far: 3084.4035087
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.

On to step 14:
57 goes into 410 7 times with a remainder of 11.
Record the quotient 7 as the next digit in the result. 
Result so far: 3084.40350877
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.

The quotient of the division is 3084.40350877, and the remainder is 1.1e-08.
