Let's divide 78323945 by 878
The aim is to understand the frequency of 878 in 78323945.

Step 1:
When dividing 7 by 878, we get 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Fetch the next digit (8) from the dividend, attach it to 7 and continue: 78 / 878

Let's proceed to step 2:
If we divide 78 by 878, we get 0 and a remainder of 78.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 78 to get 78.
Take the next digit (3) from the dividend and append it to 78, then repeat: 783 / 878

Moving on to step 3:
If we divide 783 by 878, we get 0 and a remainder of 783.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 783, we end up with 783.
Take the next digit (2) from the dividend and append it to 783, then repeat: 7832 / 878

Let's proceed to step 4:
If we divide 7832 by 878, we get 8 and a remainder of 808.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
The remainder is 808 after subtracting 7024 from 7832.
Append the next digit (3) from the dividend to 808 and continue with: 8083 / 878

On to step 5:
878 can be fit into 8083 9 times, resulting in a remainder of 181.
The next digit of our result is 9. 
Result so far: 89.0
The remainder is 181 after subtracting 7902 from 8083.
Fetch the next digit (9) from the dividend, attach it to 181 and continue: 1819 / 878

Moving on to step 6:
1819 divided by 878 is 2 with a remainder of 63.
Use 2 as the next digit of our solution. 
Result so far: 892.0
Subtract 1756 from 1819 to get 63.
Take the next digit (4) from the dividend and append it to 63, then repeat: 634 / 878

Step 7:
634 divided by 878 is 0 with a remainder of 634.
The next digit of our result is 0. 
Result so far: 8920.0
The remainder is 634 after subtracting 0 from 634.
Include the next digit (5) from the dividend after 634, then repeat: 6345 / 878

Let's proceed to step 8:
When dividing 6345 by 878, we get 7 with a remainder of 199.
Record the quotient 7 as the next digit in the result. 
Result so far: 89207.0
Subtract 6146 from 6345 to get 199.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1990, and continue the process.

On to step 9:
878 can be fit into 1990 2 times, resulting in a remainder of 234.
Write down 2 as next digit of the result. 
Result so far: 89207.2
Deduct 1756 from 1990 and we're left with 234.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2340, and continue the process.

Let's proceed to step 10:
878 can be fit into 2340 2 times, resulting in a remainder of 584.
Put 2 as the next digit of the answer. 
Result so far: 89207.22
The remainder is 584 after subtracting 1756 from 2340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5840, and continue the process.

The quotient of the division is 89207.22, and the remainder is 0.584.
