We're dividing 756782 by 57 
The aim is to understand the frequency of 57 in 756782.

On to step 1:
The number 57 fits into 7 0 times, leaving a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Grab the next digit (5) from the dividend, add it to 7, then carry on: 75 / 57

Going ahead to step 2:
57 can be fit into 75 1 times, resulting in a remainder of 18.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 57 from 75 and we're left with 18.
Take the next digit (6) from the dividend and append it to 18, then repeat: 186 / 57

Advancing to step 3:
186 divided by 57 is 3 with a remainder of 15.
Put 3 as the next digit of the answer. 
Result so far: 13.0
Subtract 171 from 186 to get 15.
Fetch the next digit (7) from the dividend, attach it to 15 and continue: 157 / 57

Step 4:
157 divided by 57 is 2 with a remainder of 43.
Use 2 as the next digit of our solution. 
Result so far: 132.0
Deduct 114 from 157 and we're left with 43.
Take the next digit (8) from the dividend and append it to 43, then repeat: 438 / 57

Let's proceed to step 5:
438 divided by 57 is 7 with a remainder of 39.
Record the quotient 7 as the next digit in the result. 
Result so far: 1327.0
The remainder is 39 after subtracting 399 from 438.
Grab the next digit (2) from the dividend, add it to 39, then carry on: 392 / 57

Step 6:
392 divided by 57 is 6 with a remainder of 50.
Write down 6 as next digit of the result. 
Result so far: 13276.0
Subtracting 342 from 392 leaves us 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 7:
57 goes into 500 8 times with a remainder of 44.
Put 8 as the next digit of the answer. 
Result so far: 13276.8
If we subtract 456 from 500, we get 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 8:
57 goes into 440 7 times with a remainder of 41.
Write down 7 as next digit of the result. 
Result so far: 13276.87
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.

On to step 9:
If we divide 410 by 57, we get 7 and a remainder of 11.
The number 7 becomes the next digit in our result. 
Result so far: 13276.877
Subtracting 399 from 410 leaves us 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 outcome is 13276.877, with a leftover of 0.0011.
