We're dividing 124642 by 57 
The aim is to understand the frequency of 57 in 124642.

On to step 1:
The number 57 fits into 1 0 times, leaving a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Grab the next digit (2) from the dividend, add it to 1, then carry on: 12 / 57

Let's proceed to step 2:
57 can be fit into 12 0 times, resulting in a remainder of 12.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 12 leaves us with 12.
Append the next digit (4) from the dividend to 12 and continue with: 124 / 57

On to step 3:
When dividing 124 by 57, we get 2 with a remainder of 10.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
The remainder is 10 after subtracting 114 from 124.
Fetch the next digit (6) from the dividend, attach it to 10 and continue: 106 / 57

Let's proceed to step 4:
The number 57 fits into 106 1 times, leaving a remainder of 49.
Write down 1 as next digit of the result. 
Result so far: 21.0
Subtracting 57 from 106 leaves us with 49.
Fetch the next digit (4) from the dividend, attach it to 49 and continue: 494 / 57

Advancing to step 5:
The number 57 fits into 494 8 times, leaving a remainder of 38.
The next digit of our result is 8. 
Result so far: 218.0
The remainder is 38 after subtracting 456 from 494.
Bring next digit (2) of the dividend behind the 38 and repeat the process: 382 / 57

Let's proceed to step 6:
When dividing 382 by 57, we get 6 with a remainder of 40.
The next digit of our result is 6. 
Result so far: 2186.0
Deduct 342 from 382 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 7:
400 divided by 57 is 7 with a remainder of 1.
Put 7 as the next digit of the answer. 
Result so far: 2186.7
Subtracting 399 from 400 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 8:
57 goes into 10 0 times with a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 2186.7
Subtracting 0 from 10 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 9:
57 can be fit into 100 1 times, resulting in a remainder of 43.
Write down 1 as next digit of the result. 
Result so far: 2186.701
Subtract 57 from 100 to get 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Step 10:
430 divided by 57 is 7 with a remainder of 31.
Use 7 as the next digit of our solution. 
Result so far: 2186.7017
Subtracting 399 from 430 leaves us with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

On to step 11:
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: 2186.70175
If we take 285 away from 310, we end up with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Step 12:
If we divide 250 by 57, we get 4 and a remainder of 22.
Write down 4 as next digit of the result. 
Result so far: 2186.701754
If we take 228 away from 250, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 13:
If we divide 220 by 57, we get 3 and a remainder of 49.
The next digit of our result is 3. 
Result so far: 2186.7017543
Subtracting 171 from 220 leaves us with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Step 14:
If we divide 490 by 57, we get 8 and a remainder of 34.
The number 8 becomes the next digit in our result. 
Result so far: 2186.70175438
The remainder is 34 after subtracting 456 from 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

In conclusion, the division gives 2186.70175438 with a balance of 3.4e-08.
