81745 ÷ 57 
The aim is to understand the frequency of 57 in 81745.

On to step 1:
When dividing 8 by 57, we get 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Include the next digit (1) from the dividend after 8, then repeat: 81 / 57

Let's proceed to step 2:
The number 57 fits into 81 1 times, leaving a remainder of 24.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 57 from 81 leaves us with 24.
Grab the next digit (7) from the dividend, add it to 24, then carry on: 247 / 57

Let's proceed to step 3:
When dividing 247 by 57, we get 4 with a remainder of 19.
The number 4 becomes the next digit in our result. 
Result so far: 14.0
Subtract 228 from 247 to get 19.
Grab the next digit (4) from the dividend, add it to 19, then carry on: 194 / 57

Step 4:
57 can be fit into 194 3 times, resulting in a remainder of 23.
Record the quotient 3 as the next digit in the result. 
Result so far: 143.0
If we take 171 away from 194, we end up with 23.
Take the next digit (5) from the dividend and append it to 23, then repeat: 235 / 57

Moving on to step 5:
235 divided by 57 is 4 with a remainder of 7.
Write down 4 as next digit of the result. 
Result so far: 1434.0
Deduct 228 from 235 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 6:
70 divided by 57 is 1 with a remainder of 13.
The next digit of our result is 1. 
Result so far: 1434.1
If we take 57 away from 70, we end up 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.

Going ahead to step 7:
130 divided by 57 is 2 with a remainder of 16.
The next digit of our result is 2. 
Result so far: 1434.12
Subtracting 114 from 130 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 8:
If we divide 160 by 57, we get 2 and a remainder of 46.
Use 2 as the next digit of our solution. 
Result so far: 1434.122
If we subtract 114 from 160, we get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Our division results in 1434.122 with a remaining 0.0046.
