We look at the division of 39978686 by 56 
The aim is to understand the frequency of 56 in 39978686.

Let's proceed to step 1:
3 divided by 56 is 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Bring next digit (9) of the dividend behind the 3 and repeat the process: 39 / 56

Advancing to step 2:
If we divide 39 by 56, we get 0 and a remainder of 39.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 39, we get 39.
Fetch the next digit (9) from the dividend, attach it to 39 and continue: 399 / 56

Moving on to step 3:
The number 56 fits into 399 7 times, leaving a remainder of 7.
Write down 7 as next digit of the result. 
Result so far: 7.0
If we subtract 392 from 399, we get 7.
Take the next digit (7) from the dividend and append it to 7, then repeat: 77 / 56

Step 4:
The number 56 fits into 77 1 times, leaving a remainder of 21.
The number 1 becomes the next digit in our result. 
Result so far: 71.0
If we subtract 56 from 77, we get 21.
Take the next digit (8) from the dividend and append it to 21, then repeat: 218 / 56

Moving on to step 5:
56 goes into 218 3 times with a remainder of 50.
The next digit of our result is 3. 
Result so far: 713.0
If we subtract 168 from 218, we get 50.
Bring next digit (6) of the dividend behind the 50 and repeat the process: 506 / 56

Going ahead to step 6:
56 goes into 506 9 times with a remainder of 2.
Put 9 as the next digit of the answer. 
Result so far: 7139.0
Subtract 504 from 506 to get 2.
Fetch the next digit (8) from the dividend, attach it to 2 and continue: 28 / 56

Let's proceed to step 7:
56 can be fit into 28 0 times, resulting in a remainder of 28.
Record the quotient 0 as the next digit in the result. 
Result so far: 71390.0
Subtract 0 from 28 to get 28.
Grab the next digit (6) from the dividend, add it to 28, then carry on: 286 / 56

Going ahead to step 8:
286 divided by 56 is 5 with a remainder of 6.
The next digit of our result is 5. 
Result so far: 713905.0
Subtracting 280 from 286 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 9:
56 goes into 60 1 times with a remainder of 4.
Put 1 as the next digit of the answer. 
Result so far: 713905.1
The remainder is 4 after subtracting 56 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 10:
56 can be fit into 40 0 times, resulting in a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 713905.1
Deduct 0 from 40 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.

Going ahead to step 11:
The number 56 fits into 400 7 times, leaving a remainder of 8.
Use 7 as the next digit of our solution. 
Result so far: 713905.107
If we take 392 away from 400, we end up with 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 12:
If we divide 80 by 56, we get 1 and a remainder of 24.
Use 1 as the next digit of our solution. 
Result so far: 713905.1071
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.

Going ahead to step 13:
The number 56 fits into 240 4 times, leaving a remainder of 16.
Record the quotient 4 as the next digit in the result. 
Result so far: 713905.10714
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.

Let's proceed to step 14:
56 goes into 160 2 times with a remainder of 48.
The number 2 becomes the next digit in our result. 
Result so far: 713905.107142
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.

Moving on to step 15:
The number 56 fits into 480 8 times, leaving a remainder of 32.
Put 8 as the next digit of the answer. 
Result so far: 713905.1071428
If we take 448 away from 480, we end up 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.

Let's proceed to step 16:
56 goes into 320 5 times with a remainder of 40.
The next digit of our result is 5. 
Result so far: 713905.10714285
Subtract 280 from 320 to 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.

The final result is 713905.10714285 with a remainder of 4e-08.
