Let's divide 390109 by 56
The aim is to understand the frequency of 56 in 390109.

Step 1:
When dividing 3 by 56, we get 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Bring next digit (9) of the dividend behind the 3 and repeat the process: 39 / 56

Advancing to step 2:
39 divided by 56 is 0 with a remainder of 39.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 39 after subtracting 0 from 39.
Include the next digit (0) from the dividend after 39, then repeat: 390 / 56

Let's proceed to step 3:
If we divide 390 by 56, we get 6 and a remainder of 54.
Use 6 as the next digit of our solution. 
Result so far: 6.0
If we subtract 336 from 390, we get 54.
Bring next digit (1) of the dividend behind the 54 and repeat the process: 541 / 56

Moving on to step 4:
541 divided by 56 is 9 with a remainder of 37.
Put 9 as the next digit of the answer. 
Result so far: 69.0
If we subtract 504 from 541, we get 37.
Take the next digit (0) from the dividend and append it to 37, then repeat: 370 / 56

Advancing to step 5:
56 can be fit into 370 6 times, resulting in a remainder of 34.
Record the quotient 6 as the next digit in the result. 
Result so far: 696.0
The remainder is 34 after subtracting 336 from 370.
Bring next digit (9) of the dividend behind the 34 and repeat the process: 349 / 56

Let's proceed to step 6:
If we divide 349 by 56, we get 6 and a remainder of 13.
Use 6 as the next digit of our solution. 
Result so far: 6966.0
The remainder is 13 after subtracting 336 from 349.
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 7:
56 goes into 130 2 times with a remainder of 18.
The next digit of our result is 2. 
Result so far: 6966.2
Subtract 112 from 130 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 8:
56 goes into 180 3 times with a remainder of 12.
Use 3 as the next digit of our solution. 
Result so far: 6966.23
Deduct 168 from 180 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 9:
120 divided by 56 is 2 with a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 6966.232
If we subtract 112 from 120, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 10:
56 can be fit into 80 1 times, resulting in a remainder of 24.
Use 1 as the next digit of our solution. 
Result so far: 6966.2321
Subtracting 56 from 80 leaves us 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.

Advancing to step 11:
56 goes into 240 4 times with a remainder of 16.
The number 4 becomes the next digit in our result. 
Result so far: 6966.23214
The remainder is 16 after subtracting 224 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 12:
When dividing 160 by 56, we get 2 with a remainder of 48.
The number 2 becomes the next digit in our result. 
Result so far: 6966.232142
The remainder is 48 after subtracting 112 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Advancing to step 13:
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: 6966.2321428
If we subtract 448 from 480, we 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 14:
56 goes into 320 5 times with a remainder of 40.
The next digit of our result is 5. 
Result so far: 6966.23214285
Deduct 280 from 320 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.

The final outcome is 6966.23214285, with a leftover of 4e-08.
