We look at the division of 913060 by 57 
The aim is to understand the frequency of 57 in 913060.

Advancing to step 1:
If we divide 9 by 57, we get 0 and a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Take the next digit (1) from the dividend and append it to 9, then repeat: 91 / 57

Going ahead to step 2:
57 goes into 91 1 times with a remainder of 34.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 34 after subtracting 57 from 91.
Include the next digit (3) from the dividend after 34, then repeat: 343 / 57

Step 3:
343 divided by 57 is 6 with a remainder of 1.
The number 6 becomes the next digit in our result. 
Result so far: 16.0
Subtract 342 from 343 to get 1.
Take the next digit (0) from the dividend and append it to 1, then repeat: 10 / 57

Let's proceed to step 4:
10 divided by 57 is 0 with a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 160.0
The remainder is 10 after subtracting 0 from 10.
Grab the next digit (6) from the dividend, add it to 10, then carry on: 106 / 57

Moving on to step 5:
57 goes into 106 1 times with a remainder of 49.
The next digit of our result is 1. 
Result so far: 1601.0
Subtract 57 from 106 to get 49.
Include the next digit (0) from the dividend after 49, then repeat: 490 / 57

Step 6:
57 goes into 490 8 times with a remainder of 34.
The number 8 becomes the next digit in our result. 
Result so far: 16018.0
Subtracting 456 from 490 leaves us with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Moving on to step 7:
340 divided by 57 is 5 with a remainder of 55.
The number 5 becomes the next digit in our result. 
Result so far: 16018.5
Subtract 285 from 340 to get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Step 8:
57 can be fit into 550 9 times, resulting in a remainder of 37.
Write down 9 as next digit of the result. 
Result so far: 16018.59
The remainder is 37 after subtracting 513 from 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

On to step 9:
370 divided by 57 is 6 with a remainder of 28.
Put 6 as the next digit of the answer. 
Result so far: 16018.596
Deduct 342 from 370 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 10:
57 goes into 280 4 times with a remainder of 52.
Use 4 as the next digit of our solution. 
Result so far: 16018.5964
The remainder is 52 after subtracting 228 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Going ahead to step 11:
520 divided by 57 is 9 with a remainder of 7.
Record the quotient 9 as the next digit in the result. 
Result so far: 16018.59649
Subtract 513 from 520 to get 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 12:
70 divided by 57 is 1 with a remainder of 13.
Record the quotient 1 as the next digit in the result. 
Result so far: 16018.596491
Deduct 57 from 70 and we're left with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Step 13:
When dividing 130 by 57, we get 2 with a remainder of 16.
Record the quotient 2 as the next digit in the result. 
Result so far: 16018.5964912
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.

Going ahead to step 14:
57 goes into 160 2 times with a remainder of 46.
Put 2 as the next digit of the answer. 
Result so far: 16018.59649122
The remainder is 46 after subtracting 114 from 160.
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 16018.59649122 and a remainder of 4.6e-08.
