We're dividing 87262 by 57 
The aim is to understand the frequency of 57 in 87262.

Going ahead to step 1:
The number 57 fits into 8 0 times, leaving a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Bring next digit (7) of the dividend behind the 8 and repeat the process: 87 / 57

On to step 2:
If we divide 87 by 57, we get 1 and a remainder of 30.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 57 from 87 and we're left with 30.
Fetch the next digit (2) from the dividend, attach it to 30 and continue: 302 / 57

Going ahead to step 3:
57 goes into 302 5 times with a remainder of 17.
The next digit of our result is 5. 
Result so far: 15.0
The remainder is 17 after subtracting 285 from 302.
Fetch the next digit (6) from the dividend, attach it to 17 and continue: 176 / 57

Moving on to step 4:
176 divided by 57 is 3 with a remainder of 5.
Use 3 as the next digit of our solution. 
Result so far: 153.0
Deduct 171 from 176 and we're left with 5.
Fetch the next digit (2) from the dividend, attach it to 5 and continue: 52 / 57

On to step 5:
If we divide 52 by 57, we get 0 and a remainder of 52.
The next digit of our result is 0. 
Result so far: 1530.0
Deduct 0 from 52 and we're left with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Step 6:
57 goes into 520 9 times with a remainder of 7.
Put 9 as the next digit of the answer. 
Result so far: 1530.9
Subtracting 513 from 520 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.

Let's proceed to step 7:
If we divide 70 by 57, we get 1 and a remainder of 13.
Put 1 as the next digit of the answer. 
Result so far: 1530.91
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.

Let's proceed to step 8:
57 can be fit into 130 2 times, resulting in a remainder of 16.
Put 2 as the next digit of the answer. 
Result so far: 1530.912
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.

On to step 9:
The number 57 fits into 160 2 times, leaving a remainder of 46.
The next digit of our result is 2. 
Result so far: 1530.9122
Subtracting 114 from 160 leaves us with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

After the division, we end up with 1530.9122 and a remainder of 0.00046.
