We look at the division of 662057 by 57 
The aim is to understand the frequency of 57 in 662057.

Step 1:
When dividing 6 by 57, we get 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Include the next digit (6) from the dividend after 6, then repeat: 66 / 57

On to step 2:
When dividing 66 by 57, we get 1 with a remainder of 9.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 57 from 66 and we're left with 9.
Fetch the next digit (2) from the dividend, attach it to 9 and continue: 92 / 57

Step 3:
When dividing 92 by 57, we get 1 with a remainder of 35.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
The remainder is 35 after subtracting 57 from 92.
Append the next digit (0) from the dividend to 35 and continue with: 350 / 57

Step 4:
57 can be fit into 350 6 times, resulting in a remainder of 8.
Use 6 as the next digit of our solution. 
Result so far: 116.0
If we take 342 away from 350, we end up with 8.
Append the next digit (5) from the dividend to 8 and continue with: 85 / 57

Let's proceed to step 5:
57 goes into 85 1 times with a remainder of 28.
Put 1 as the next digit of the answer. 
Result so far: 1161.0
Deduct 57 from 85 and we're left with 28.
Include the next digit (7) from the dividend after 28, then repeat: 287 / 57

Going ahead to step 6:
If we divide 287 by 57, we get 5 and a remainder of 2.
Put 5 as the next digit of the answer. 
Result so far: 11615.0
If we take 285 away from 287, we end up 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.

Let's proceed to step 7:
When dividing 20 by 57, we get 0 with a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 11615.0
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 8:
If we divide 200 by 57, we get 3 and a remainder of 29.
The number 3 becomes the next digit in our result. 
Result so far: 11615.03
Deduct 171 from 200 and we're left with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Going ahead to step 9:
When dividing 290 by 57, we get 5 with a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 11615.035
Subtracting 285 from 290 leaves us 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.

Going ahead to step 10:
If we divide 50 by 57, we get 0 and a remainder of 50.
Write down 0 as next digit of the result. 
Result so far: 11615.035
Subtract 0 from 50 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 11:
The number 57 fits into 500 8 times, leaving a remainder of 44.
Write down 8 as next digit of the result. 
Result so far: 11615.03508
If we take 456 away from 500, we end up 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.

Going ahead to step 12:
When dividing 440 by 57, we get 7 with a remainder of 41.
Write down 7 as next digit of the result. 
Result so far: 11615.035087
Subtract 399 from 440 to get 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 13:
If we divide 410 by 57, we get 7 and a remainder of 11.
The next digit of our result is 7. 
Result so far: 11615.0350877
Deduct 399 from 410 and we're left 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 final result is 11615.0350877 with a remainder of 1.1e-07.
