We're dividing 72678832 by 878 
The aim is to understand the frequency of 878 in 72678832.

Going ahead to step 1:
878 goes into 7 0 times with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Grab the next digit (2) from the dividend, add it to 7, then carry on: 72 / 878

On to step 2:
The number 878 fits into 72 0 times, leaving a remainder of 72.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 72 and we're left with 72.
Append the next digit (6) from the dividend to 72 and continue with: 726 / 878

Moving on to step 3:
If we divide 726 by 878, we get 0 and a remainder of 726.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 726, we get 726.
Bring next digit (7) of the dividend behind the 726 and repeat the process: 7267 / 878

Step 4:
When dividing 7267 by 878, we get 8 with a remainder of 243.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
Subtracting 7024 from 7267 leaves us with 243.
Bring next digit (8) of the dividend behind the 243 and repeat the process: 2438 / 878

Advancing to step 5:
The number 878 fits into 2438 2 times, leaving a remainder of 682.
The number 2 becomes the next digit in our result. 
Result so far: 82.0
If we subtract 1756 from 2438, we get 682.
Append the next digit (8) from the dividend to 682 and continue with: 6828 / 878

Step 6:
When dividing 6828 by 878, we get 7 with a remainder of 682.
Write down 7 as next digit of the result. 
Result so far: 827.0
If we take 6146 away from 6828, we end up with 682.
Fetch the next digit (3) from the dividend, attach it to 682 and continue: 6823 / 878

Let's proceed to step 7:
The number 878 fits into 6823 7 times, leaving a remainder of 677.
The next digit of our result is 7. 
Result so far: 8277.0
Subtract 6146 from 6823 to get 677.
Include the next digit (2) from the dividend after 677, then repeat: 6772 / 878

On to step 8:
If we divide 6772 by 878, we get 7 and a remainder of 626.
The next digit of our result is 7. 
Result so far: 82777.0
The remainder is 626 after subtracting 6146 from 6772.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6260, and continue the process.

Let's proceed to step 9:
If we divide 6260 by 878, we get 7 and a remainder of 114.
Write down 7 as next digit of the result. 
Result so far: 82777.7
Subtract 6146 from 6260 to get 114.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

On to step 10:
878 can be fit into 1140 1 times, resulting in a remainder of 262.
Put 1 as the next digit of the answer. 
Result so far: 82777.71
Subtracting 878 from 1140 leaves us with 262.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2620, and continue the process.

Step 11:
If we divide 2620 by 878, we get 2 and a remainder of 864.
Write down 2 as next digit of the result. 
Result so far: 82777.712
Deduct 1756 from 2620 and we're left with 864.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8640, and continue the process.

Let's proceed to step 12:
878 goes into 8640 9 times with a remainder of 738.
The next digit of our result is 9. 
Result so far: 82777.7129
The remainder is 738 after subtracting 7902 from 8640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7380, and continue the process.

Moving on to step 13:
The number 878 fits into 7380 8 times, leaving a remainder of 356.
Use 8 as the next digit of our solution. 
Result so far: 82777.71298
Subtract 7024 from 7380 to get 356.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3560, and continue the process.

On to step 14:
The number 878 fits into 3560 4 times, leaving a remainder of 48.
Write down 4 as next digit of the result. 
Result so far: 82777.712984
Subtracting 3512 from 3560 leaves us 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.

Step 15:
When dividing 480 by 878, we get 0 with a remainder of 480.
The number 0 becomes the next digit in our result. 
Result so far: 82777.712984
Subtract 0 from 480 to get 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Let's proceed to step 16:
The number 878 fits into 4800 5 times, leaving a remainder of 410.
The next digit of our result is 5. 
Result so far: 82777.71298405
If we take 4390 away from 4800, we end up with 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4100, and continue the process.

After the division, we end up with 82777.71298405 and a remainder of 4.1e-07.
