780557 ÷ 56 
The aim is to understand the frequency of 56 in 780557.

Advancing to step 1:
56 can be fit into 7 0 times, resulting in a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Take the next digit (8) from the dividend and append it to 7, then repeat: 78 / 56

Advancing to step 2:
If we divide 78 by 56, we get 1 and a remainder of 22.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 22 after subtracting 56 from 78.
Bring next digit (0) of the dividend behind the 22 and repeat the process: 220 / 56

Step 3:
56 goes into 220 3 times with a remainder of 52.
Use 3 as the next digit of our solution. 
Result so far: 13.0
If we take 168 away from 220, we end up with 52.
Bring next digit (5) of the dividend behind the 52 and repeat the process: 525 / 56

Step 4:
When dividing 525 by 56, we get 9 with a remainder of 21.
The next digit of our result is 9. 
Result so far: 139.0
Deduct 504 from 525 and we're left with 21.
Take the next digit (5) from the dividend and append it to 21, then repeat: 215 / 56

Let's proceed to step 5:
When dividing 215 by 56, we get 3 with a remainder of 47.
The number 3 becomes the next digit in our result. 
Result so far: 1393.0
Subtracting 168 from 215 leaves us with 47.
Grab the next digit (7) from the dividend, add it to 47, then carry on: 477 / 56

Step 6:
56 goes into 477 8 times with a remainder of 29.
The next digit of our result is 8. 
Result so far: 13938.0
If we subtract 448 from 477, we get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Step 7:
The number 56 fits into 290 5 times, leaving a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 13938.5
Subtracting 280 from 290 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.

Let's proceed to step 8:
If we divide 100 by 56, we get 1 and a remainder of 44.
Put 1 as the next digit of the answer. 
Result so far: 13938.51
The remainder is 44 after subtracting 56 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

On to step 9:
440 divided by 56 is 7 with a remainder of 48.
The number 7 becomes the next digit in our result. 
Result so far: 13938.517
Subtracting 392 from 440 leaves us 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 10:
480 divided by 56 is 8 with a remainder of 32.
Record the quotient 8 as the next digit in the result. 
Result so far: 13938.5178
Subtract 448 from 480 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.

Going ahead to step 11:
If we divide 320 by 56, we get 5 and a remainder of 40.
The number 5 becomes the next digit in our result. 
Result so far: 13938.51785
The remainder is 40 after subtracting 280 from 320.
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 12:
56 goes into 400 7 times with a remainder of 8.
The number 7 becomes the next digit in our result. 
Result so far: 13938.517857
If we subtract 392 from 400, 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.

On to step 13:
56 goes into 80 1 times with a remainder of 24.
Record the quotient 1 as the next digit in the result. 
Result so far: 13938.5178571
Deduct 56 from 80 and we're left 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.

Step 14:
240 divided by 56 is 4 with a remainder of 16.
Write down 4 as next digit of the result. 
Result so far: 13938.51785714
Subtracting 224 from 240 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.

The final result is 13938.51785714 with a remainder of 1.6e-08.
