880231 divided by 57 
The aim is to understand the frequency of 57 in 880231.

Advancing to step 1:
8 divided by 57 is 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Include the next digit (8) from the dividend after 8, then repeat: 88 / 57

Moving on to step 2:
88 divided by 57 is 1 with a remainder of 31.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 57 from 88 leaves us with 31.
Include the next digit (0) from the dividend after 31, then repeat: 310 / 57

Let's proceed to step 3:
When dividing 310 by 57, we get 5 with a remainder of 25.
Record the quotient 5 as the next digit in the result. 
Result so far: 15.0
The remainder is 25 after subtracting 285 from 310.
Append the next digit (2) from the dividend to 25 and continue with: 252 / 57

Moving on to step 4:
57 goes into 252 4 times with a remainder of 24.
Write down 4 as next digit of the result. 
Result so far: 154.0
If we take 228 away from 252, we end up with 24.
Take the next digit (3) from the dividend and append it to 24, then repeat: 243 / 57

Going ahead to step 5:
57 can be fit into 243 4 times, resulting in a remainder of 15.
Put 4 as the next digit of the answer. 
Result so far: 1544.0
Deduct 228 from 243 and we're left with 15.
Take the next digit (1) from the dividend and append it to 15, then repeat: 151 / 57

Let's proceed to step 6:
If we divide 151 by 57, we get 2 and a remainder of 37.
The next digit of our result is 2. 
Result so far: 15442.0
If we take 114 away from 151, we end up with 37.
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 7:
57 can be fit into 370 6 times, resulting in a remainder of 28.
The number 6 becomes the next digit in our result. 
Result so far: 15442.6
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.

On to step 8:
57 goes into 280 4 times with a remainder of 52.
The number 4 becomes the next digit in our result. 
Result so far: 15442.64
If we subtract 228 from 280, we get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Let's proceed to step 9:
57 goes into 520 9 times with a remainder of 7.
Record the quotient 9 as the next digit in the result. 
Result so far: 15442.649
Subtracting 513 from 520 leaves us 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.

Step 10:
If we divide 70 by 57, we get 1 and a remainder of 13.
Use 1 as the next digit of our solution. 
Result so far: 15442.6491
If we subtract 57 from 70, we get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

On to step 11:
57 can be fit into 130 2 times, resulting in a remainder of 16.
Use 2 as the next digit of our solution. 
Result so far: 15442.64912
Deduct 114 from 130 and we're left 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.

On to step 12:
When dividing 160 by 57, we get 2 with a remainder of 46.
Write down 2 as next digit of the result. 
Result so far: 15442.649122
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 15442.649122 and a remainder of 4.6e-06.
