We divide 2143 by 57
The aim is to understand the frequency of 57 in 2143.

Let's proceed to step 1:
When dividing 2 by 57, we get 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 57

Step 2:
21 divided by 57 is 0 with a remainder of 21.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 21 after subtracting 0 from 21.
Take the next digit (4) from the dividend and append it to 21, then repeat: 214 / 57

Going ahead to step 3:
57 goes into 214 3 times with a remainder of 43.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we take 171 away from 214, we end up with 43.
Take the next digit (3) from the dividend and append it to 43, then repeat: 433 / 57

Going ahead to step 4:
If we divide 433 by 57, we get 7 and a remainder of 34.
The number 7 becomes the next digit in our result. 
Result so far: 37.0
The remainder is 34 after subtracting 399 from 433.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Moving on to step 5:
The number 57 fits into 340 5 times, leaving a remainder of 55.
The next digit of our result is 5. 
Result so far: 37.5
Deduct 285 from 340 and we're left with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Advancing to step 6:
The number 57 fits into 550 9 times, leaving a remainder of 37.
Use 9 as the next digit of our solution. 
Result so far: 37.59
Subtract 513 from 550 to get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Going ahead to step 7:
57 goes into 370 6 times with a remainder of 28.
Record the quotient 6 as the next digit in the result. 
Result so far: 37.596
Subtract 342 from 370 to get 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 can be fit into 280 4 times, resulting in a remainder of 52.
Use 4 as the next digit of our solution. 
Result so far: 37.5964
Subtract 228 from 280 to 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.

Step 9:
520 divided by 57 is 9 with a remainder of 7.
Write down 9 as next digit of the result. 
Result so far: 37.59649
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.

Going ahead to step 10:
70 divided by 57 is 1 with a remainder of 13.
Put 1 as the next digit of the answer. 
Result so far: 37.596491
Subtract 57 from 70 to 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.

Advancing to step 11:
When dividing 130 by 57, we get 2 with a remainder of 16.
Use 2 as the next digit of our solution. 
Result so far: 37.5964912
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.

On to step 12:
If we divide 160 by 57, we get 2 and a remainder of 46.
Write down 2 as next digit of the result. 
Result so far: 37.59649122
Subtracting 114 from 160 leaves us with 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 37.59649122 with a remaining 4.6e-08.
