We look at the division of 785582 by 57 
The aim is to understand the frequency of 57 in 785582.

Moving on to step 1:
If we divide 7 by 57, we get 0 and a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Grab the next digit (8) from the dividend, add it to 7, then carry on: 78 / 57

Going ahead to step 2:
57 can be fit into 78 1 times, resulting in a remainder of 21.
The next digit of our result is 1. 
Result so far: 1.0
If we take 57 away from 78, we end up with 21.
Include the next digit (5) from the dividend after 21, then repeat: 215 / 57

Step 3:
57 can be fit into 215 3 times, resulting in a remainder of 44.
The next digit of our result is 3. 
Result so far: 13.0
If we subtract 171 from 215, we get 44.
Include the next digit (5) from the dividend after 44, then repeat: 445 / 57

On to step 4:
When dividing 445 by 57, we get 7 with a remainder of 46.
Use 7 as the next digit of our solution. 
Result so far: 137.0
Deduct 399 from 445 and we're left with 46.
Include the next digit (8) from the dividend after 46, then repeat: 468 / 57

Step 5:
If we divide 468 by 57, we get 8 and a remainder of 12.
Use 8 as the next digit of our solution. 
Result so far: 1378.0
Subtract 456 from 468 to get 12.
Grab the next digit (2) from the dividend, add it to 12, then carry on: 122 / 57

Going ahead to step 6:
If we divide 122 by 57, we get 2 and a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 13782.0
Deduct 114 from 122 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 7:
If we divide 80 by 57, we get 1 and a remainder of 23.
Put 1 as the next digit of the answer. 
Result so far: 13782.1
If we take 57 away from 80, we end up 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.

Moving on to step 8:
If we divide 230 by 57, we get 4 and a remainder of 2.
The next digit of our result is 4. 
Result so far: 13782.14
The remainder is 2 after subtracting 228 from 230.
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 9:
20 divided by 57 is 0 with a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 13782.14
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.

Step 10:
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: 13782.1403
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.

Moving on to step 11:
57 goes into 290 5 times with a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 13782.14035
Subtract 285 from 290 to 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.

Let's proceed to step 12:
When dividing 50 by 57, we get 0 with a remainder of 50.
Put 0 as the next digit of the answer. 
Result so far: 13782.14035
Deduct 0 from 50 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 13:
If we divide 500 by 57, we get 8 and a remainder of 44.
Write down 8 as next digit of the result. 
Result so far: 13782.1403508
Deduct 456 from 500 and we're left 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.

Advancing to step 14:
The number 57 fits into 440 7 times, leaving a remainder of 41.
The number 7 becomes the next digit in our result. 
Result so far: 13782.14035087
Subtracting 399 from 440 leaves us 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.

The final outcome is 13782.14035087, with a leftover of 4.1e-08.
