We're dividing 6640581 by 56 
The aim is to understand the frequency of 56 in 6640581.

On to step 1:
The number 56 fits into 6 0 times, leaving a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Append the next digit (6) from the dividend to 6 and continue with: 66 / 56

On to step 2:
66 divided by 56 is 1 with a remainder of 10.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 56 from 66 and we're left with 10.
Include the next digit (4) from the dividend after 10, then repeat: 104 / 56

Step 3:
If we divide 104 by 56, we get 1 and a remainder of 48.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
Subtract 56 from 104 to get 48.
Bring next digit (0) of the dividend behind the 48 and repeat the process: 480 / 56

Going ahead to step 4:
When dividing 480 by 56, we get 8 with a remainder of 32.
The next digit of our result is 8. 
Result so far: 118.0
If we take 448 away from 480, we end up with 32.
Grab the next digit (5) from the dividend, add it to 32, then carry on: 325 / 56

Advancing to step 5:
The number 56 fits into 325 5 times, leaving a remainder of 45.
Write down 5 as next digit of the result. 
Result so far: 1185.0
If we subtract 280 from 325, we get 45.
Fetch the next digit (8) from the dividend, attach it to 45 and continue: 458 / 56

Going ahead to step 6:
56 goes into 458 8 times with a remainder of 10.
Use 8 as the next digit of our solution. 
Result so far: 11858.0
Subtracting 448 from 458 leaves us with 10.
Bring next digit (1) of the dividend behind the 10 and repeat the process: 101 / 56

Step 7:
The number 56 fits into 101 1 times, leaving a remainder of 45.
Write down 1 as next digit of the result. 
Result so far: 118581.0
Subtracting 56 from 101 leaves us with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Step 8:
If we divide 450 by 56, we get 8 and a remainder of 2.
Write down 8 as next digit of the result. 
Result so far: 118581.8
If we take 448 away from 450, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 9:
If we divide 20 by 56, we get 0 and a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 118581.8
Subtracting 0 from 20 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 10:
200 divided by 56 is 3 with a remainder of 32.
The next digit of our result is 3. 
Result so far: 118581.803
Subtract 168 from 200 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 11:
56 goes into 320 5 times with a remainder of 40.
Write down 5 as next digit of the result. 
Result so far: 118581.8035
If we subtract 280 from 320, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 12:
When dividing 400 by 56, we get 7 with a remainder of 8.
The number 7 becomes the next digit in our result. 
Result so far: 118581.80357
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 13:
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: 118581.803571
The remainder is 24 after subtracting 56 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 14:
56 goes into 240 4 times with a remainder of 16.
The next digit of our result is 4. 
Result so far: 118581.8035714
Subtract 224 from 240 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 15:
When dividing 160 by 56, we get 2 with a remainder of 48.
Use 2 as the next digit of our solution. 
Result so far: 118581.80357142
Deduct 112 from 160 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.

After the division, we end up with 118581.80357142 and a remainder of 4.8e-08.
