28425168 ÷ 878 
The aim is to understand the frequency of 878 in 28425168.

Step 1:
2 divided by 878 is 0 with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Append the next digit (8) from the dividend to 2 and continue with: 28 / 878

Let's proceed to step 2:
878 can be fit into 28 0 times, resulting in a remainder of 28.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 28, we get 28.
Take the next digit (4) from the dividend and append it to 28, then repeat: 284 / 878

Advancing to step 3:
878 can be fit into 284 0 times, resulting in a remainder of 284.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 284, we get 284.
Include the next digit (2) from the dividend after 284, then repeat: 2842 / 878

Going ahead to step 4:
If we divide 2842 by 878, we get 3 and a remainder of 208.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Deduct 2634 from 2842 and we're left with 208.
Append the next digit (5) from the dividend to 208 and continue with: 2085 / 878

Going ahead to step 5:
When dividing 2085 by 878, we get 2 with a remainder of 329.
Record the quotient 2 as the next digit in the result. 
Result so far: 32.0
Deduct 1756 from 2085 and we're left with 329.
Grab the next digit (1) from the dividend, add it to 329, then carry on: 3291 / 878

Step 6:
When dividing 3291 by 878, we get 3 with a remainder of 657.
The next digit of our result is 3. 
Result so far: 323.0
The remainder is 657 after subtracting 2634 from 3291.
Append the next digit (6) from the dividend to 657 and continue with: 6576 / 878

Going ahead to step 7:
878 goes into 6576 7 times with a remainder of 430.
Write down 7 as next digit of the result. 
Result so far: 3237.0
The remainder is 430 after subtracting 6146 from 6576.
Fetch the next digit (8) from the dividend, attach it to 430 and continue: 4308 / 878

Advancing to step 8:
878 goes into 4308 4 times with a remainder of 796.
The number 4 becomes the next digit in our result. 
Result so far: 32374.0
Subtracting 3512 from 4308 leaves us with 796.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7960, and continue the process.

Going ahead to step 9:
878 goes into 7960 9 times with a remainder of 58.
The next digit of our result is 9. 
Result so far: 32374.9
If we subtract 7902 from 7960, we get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Step 10:
580 divided by 878 is 0 with a remainder of 580.
Write down 0 as next digit of the result. 
Result so far: 32374.9
Subtract 0 from 580 to get 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5800, and continue the process.

Step 11:
878 can be fit into 5800 6 times, resulting in a remainder of 532.
The number 6 becomes the next digit in our result. 
Result so far: 32374.906
If we take 5268 away from 5800, we end up with 532.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5320, and continue the process.

Going ahead to step 12:
878 goes into 5320 6 times with a remainder of 52.
Write down 6 as next digit of the result. 
Result so far: 32374.9066
Deduct 5268 from 5320 and we're left with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

The final outcome is 32374.9066, with a leftover of 0.00052.
