We're dividing 42449 by 56 
The aim is to understand the frequency of 56 in 42449.

Step 1:
The number 56 fits into 4 0 times, leaving a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Append the next digit (2) from the dividend to 4 and continue with: 42 / 56

Moving on to step 2:
If we divide 42 by 56, we get 0 and a remainder of 42.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 42 and we're left with 42.
Fetch the next digit (4) from the dividend, attach it to 42 and continue: 424 / 56

Advancing to step 3:
If we divide 424 by 56, we get 7 and a remainder of 32.
Put 7 as the next digit of the answer. 
Result so far: 7.0
If we take 392 away from 424, we end up with 32.
Append the next digit (4) from the dividend to 32 and continue with: 324 / 56

Going ahead to step 4:
When dividing 324 by 56, we get 5 with a remainder of 44.
Put 5 as the next digit of the answer. 
Result so far: 75.0
If we take 280 away from 324, we end up with 44.
Bring next digit (9) of the dividend behind the 44 and repeat the process: 449 / 56

Advancing to step 5:
When dividing 449 by 56, we get 8 with a remainder of 1.
The next digit of our result is 8. 
Result so far: 758.0
Subtracting 448 from 449 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 6:
The number 56 fits into 10 0 times, leaving a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 758.0
If we take 0 away from 10, we end up 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.

Advancing to step 7:
56 can be fit into 100 1 times, resulting in a remainder of 44.
The number 1 becomes the next digit in our result. 
Result so far: 758.01
Subtract 56 from 100 to 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.

Going ahead to step 8:
56 goes into 440 7 times with a remainder of 48.
Record the quotient 7 as the next digit in the result. 
Result so far: 758.017
Deduct 392 from 440 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

On to step 9:
56 can be fit into 480 8 times, resulting in a remainder of 32.
The number 8 becomes the next digit in our result. 
Result so far: 758.0178
Deduct 448 from 480 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 10:
56 goes into 320 5 times with a remainder of 40.
Write down 5 as next digit of the result. 
Result so far: 758.01785
Subtracting 280 from 320 leaves us 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.

Advancing to step 11:
When dividing 400 by 56, we get 7 with a remainder of 8.
Put 7 as the next digit of the answer. 
Result so far: 758.017857
The remainder is 8 after subtracting 392 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 12:
The number 56 fits into 80 1 times, leaving a remainder of 24.
Use 1 as the next digit of our solution. 
Result so far: 758.0178571
If we take 56 away from 80, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 13:
If we divide 240 by 56, we get 4 and a remainder of 16.
The next digit of our result is 4. 
Result so far: 758.01785714
If we take 224 away from 240, we end up 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.

The final result is 758.01785714 with a remainder of 1.6e-08.
