73858678 divided by 879 
The aim is to understand the frequency of 879 in 73858678.

Advancing to step 1:
When dividing 7 by 879, we get 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Include the next digit (3) from the dividend after 7, then repeat: 73 / 879

Advancing to step 2:
73 divided by 879 is 0 with a remainder of 73.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 73 leaves us with 73.
Include the next digit (8) from the dividend after 73, then repeat: 738 / 879

On to step 3:
879 goes into 738 0 times with a remainder of 738.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 738 to get 738.
Append the next digit (5) from the dividend to 738 and continue with: 7385 / 879

On to step 4:
The number 879 fits into 7385 8 times, leaving a remainder of 353.
The next digit of our result is 8. 
Result so far: 8.0
Deduct 7032 from 7385 and we're left with 353.
Include the next digit (8) from the dividend after 353, then repeat: 3538 / 879

On to step 5:
The number 879 fits into 3538 4 times, leaving a remainder of 22.
The next digit of our result is 4. 
Result so far: 84.0
Subtracting 3516 from 3538 leaves us with 22.
Fetch the next digit (6) from the dividend, attach it to 22 and continue: 226 / 879

Advancing to step 6:
When dividing 226 by 879, we get 0 with a remainder of 226.
Put 0 as the next digit of the answer. 
Result so far: 840.0
If we subtract 0 from 226, we get 226.
Bring next digit (7) of the dividend behind the 226 and repeat the process: 2267 / 879

On to step 7:
2267 divided by 879 is 2 with a remainder of 509.
The next digit of our result is 2. 
Result so far: 8402.0
If we take 1758 away from 2267, we end up with 509.
Include the next digit (8) from the dividend after 509, then repeat: 5098 / 879

Advancing to step 8:
When dividing 5098 by 879, we get 5 with a remainder of 703.
Write down 5 as next digit of the result. 
Result so far: 84025.0
If we take 4395 away from 5098, we end up with 703.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7030, and continue the process.

Let's proceed to step 9:
If we divide 7030 by 879, we get 7 and a remainder of 877.
Put 7 as the next digit of the answer. 
Result so far: 84025.7
Deduct 6153 from 7030 and we're left with 877.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8770, and continue the process.

Let's proceed to step 10:
When dividing 8770 by 879, we get 9 with a remainder of 859.
Record the quotient 9 as the next digit in the result. 
Result so far: 84025.79
If we take 7911 away from 8770, we end up with 859.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8590, and continue the process.

Going ahead to step 11:
The number 879 fits into 8590 9 times, leaving a remainder of 679.
Write down 9 as next digit of the result. 
Result so far: 84025.799
The remainder is 679 after subtracting 7911 from 8590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6790, and continue the process.

In conclusion, the division gives 84025.799 with a balance of 0.0679.
