We look at the division of 982478 by 57 
The aim is to understand the frequency of 57 in 982478.

Advancing to step 1:
If we divide 9 by 57, we get 0 and a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Bring next digit (8) of the dividend behind the 9 and repeat the process: 98 / 57

Let's proceed to step 2:
If we divide 98 by 57, we get 1 and a remainder of 41.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 57 from 98 and we're left with 41.
Grab the next digit (2) from the dividend, add it to 41, then carry on: 412 / 57

Moving on to step 3:
The number 57 fits into 412 7 times, leaving a remainder of 13.
Use 7 as the next digit of our solution. 
Result so far: 17.0
If we subtract 399 from 412, we get 13.
Take the next digit (4) from the dividend and append it to 13, then repeat: 134 / 57

Let's proceed to step 4:
57 goes into 134 2 times with a remainder of 20.
The number 2 becomes the next digit in our result. 
Result so far: 172.0
Deduct 114 from 134 and we're left with 20.
Include the next digit (7) from the dividend after 20, then repeat: 207 / 57

Let's proceed to step 5:
57 goes into 207 3 times with a remainder of 36.
The number 3 becomes the next digit in our result. 
Result so far: 1723.0
The remainder is 36 after subtracting 171 from 207.
Fetch the next digit (8) from the dividend, attach it to 36 and continue: 368 / 57

On to step 6:
When dividing 368 by 57, we get 6 with a remainder of 26.
Write down 6 as next digit of the result. 
Result so far: 17236.0
Deduct 342 from 368 and we're left with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Let's proceed to step 7:
57 goes into 260 4 times with a remainder of 32.
Use 4 as the next digit of our solution. 
Result so far: 17236.4
If we take 228 away from 260, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Let's proceed to step 8:
When dividing 320 by 57, we get 5 with a remainder of 35.
Write down 5 as next digit of the result. 
Result so far: 17236.45
The remainder is 35 after subtracting 285 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

On to step 9:
If we divide 350 by 57, we get 6 and a remainder of 8.
The next digit of our result is 6. 
Result so far: 17236.456
The remainder is 8 after subtracting 342 from 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 10:
If we divide 80 by 57, we get 1 and a remainder of 23.
The next digit of our result is 1. 
Result so far: 17236.4561
Deduct 57 from 80 and we're left with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

On to step 11:
When dividing 230 by 57, we get 4 with a remainder of 2.
The number 4 becomes the next digit in our result. 
Result so far: 17236.45614
If we subtract 228 from 230, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 12:
The number 57 fits into 20 0 times, leaving a remainder of 20.
The next digit of our result is 0. 
Result so far: 17236.45614
If we take 0 away from 20, we end up 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.

Let's proceed to step 13:
57 goes into 200 3 times with a remainder of 29.
Write down 3 as next digit of the result. 
Result so far: 17236.4561403
Subtract 171 from 200 to 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.

Step 14:
57 can be fit into 290 5 times, resulting in a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 17236.45614035
If we subtract 285 from 290, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Our division results in 17236.45614035 with a remaining 5e-09.
