We look at the division of 879990 by 56 
The aim is to understand the frequency of 56 in 879990.

Advancing to step 1:
When dividing 8 by 56, we get 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Include the next digit (7) from the dividend after 8, then repeat: 87 / 56

Going ahead to step 2:
56 goes into 87 1 times with a remainder of 31.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 31 after subtracting 56 from 87.
Take the next digit (9) from the dividend and append it to 31, then repeat: 319 / 56

Step 3:
319 divided by 56 is 5 with a remainder of 39.
The number 5 becomes the next digit in our result. 
Result so far: 15.0
If we take 280 away from 319, we end up with 39.
Take the next digit (9) from the dividend and append it to 39, then repeat: 399 / 56

Step 4:
If we divide 399 by 56, we get 7 and a remainder of 7.
Use 7 as the next digit of our solution. 
Result so far: 157.0
Deduct 392 from 399 and we're left with 7.
Include the next digit (9) from the dividend after 7, then repeat: 79 / 56

On to step 5:
56 can be fit into 79 1 times, resulting in a remainder of 23.
Write down 1 as next digit of the result. 
Result so far: 1571.0
Subtracting 56 from 79 leaves us with 23.
Fetch the next digit (0) from the dividend, attach it to 23 and continue: 230 / 56

Moving on to step 6:
230 divided by 56 is 4 with a remainder of 6.
Use 4 as the next digit of our solution. 
Result so far: 15714.0
Subtract 224 from 230 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 7:
When dividing 60 by 56, we get 1 with a remainder of 4.
Write down 1 as next digit of the result. 
Result so far: 15714.1
Subtracting 56 from 60 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 8:
56 can be fit into 40 0 times, resulting in a remainder of 40.
The next digit of our result is 0. 
Result so far: 15714.1
Subtract 0 from 40 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.

Advancing to step 9:
56 can be fit into 400 7 times, resulting in a remainder of 8.
Write down 7 as next digit of the result. 
Result so far: 15714.107
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.

Step 10:
80 divided by 56 is 1 with a remainder of 24.
Put 1 as the next digit of the answer. 
Result so far: 15714.1071
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.

On to step 11:
The number 56 fits into 240 4 times, leaving a remainder of 16.
Put 4 as the next digit of the answer. 
Result so far: 15714.10714
Deduct 224 from 240 and we're left 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.

Moving on to step 12:
56 can be fit into 160 2 times, resulting in a remainder of 48.
Use 2 as the next digit of our solution. 
Result so far: 15714.107142
If we subtract 112 from 160, we get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Step 13:
480 divided by 56 is 8 with a remainder of 32.
The next digit of our result is 8. 
Result so far: 15714.1071428
Subtracting 448 from 480 leaves us 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.

On to step 14:
56 can be fit into 320 5 times, resulting in a remainder of 40.
The next digit of our result is 5. 
Result so far: 15714.10714285
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 15714.10714285 with a remainder of 4e-08.
