We're dividing 78104973 by 824 
The aim is to understand the frequency of 824 in 78104973.

On to step 1:
7 divided by 824 is 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Fetch the next digit (8) from the dividend, attach it to 7 and continue: 78 / 824

Step 2:
824 can be fit into 78 0 times, resulting in a remainder of 78.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 78, we end up with 78.
Grab the next digit (1) from the dividend, add it to 78, then carry on: 781 / 824

Let's proceed to step 3:
When dividing 781 by 824, we get 0 with a remainder of 781.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 781 to get 781.
Append the next digit (0) from the dividend to 781 and continue with: 7810 / 824

On to step 4:
824 goes into 7810 9 times with a remainder of 394.
Put 9 as the next digit of the answer. 
Result so far: 9.0
Deduct 7416 from 7810 and we're left with 394.
Grab the next digit (4) from the dividend, add it to 394, then carry on: 3944 / 824

Advancing to step 5:
824 goes into 3944 4 times with a remainder of 648.
Use 4 as the next digit of our solution. 
Result so far: 94.0
If we take 3296 away from 3944, we end up with 648.
Append the next digit (9) from the dividend to 648 and continue with: 6489 / 824

Going ahead to step 6:
When dividing 6489 by 824, we get 7 with a remainder of 721.
Write down 7 as next digit of the result. 
Result so far: 947.0
Deduct 5768 from 6489 and we're left with 721.
Append the next digit (7) from the dividend to 721 and continue with: 7217 / 824

On to step 7:
When dividing 7217 by 824, we get 8 with a remainder of 625.
Write down 8 as next digit of the result. 
Result so far: 9478.0
The remainder is 625 after subtracting 6592 from 7217.
Fetch the next digit (3) from the dividend, attach it to 625 and continue: 6253 / 824

Going ahead to step 8:
824 can be fit into 6253 7 times, resulting in a remainder of 485.
The next digit of our result is 7. 
Result so far: 94787.0
Subtract 5768 from 6253 to get 485.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4850, and continue the process.

Moving on to step 9:
824 goes into 4850 5 times with a remainder of 730.
Record the quotient 5 as the next digit in the result. 
Result so far: 94787.5
If we subtract 4120 from 4850, we get 730.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7300, and continue the process.

Advancing to step 10:
7300 divided by 824 is 8 with a remainder of 708.
Use 8 as the next digit of our solution. 
Result so far: 94787.58
The remainder is 708 after subtracting 6592 from 7300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7080, and continue the process.

Moving on to step 11:
824 can be fit into 7080 8 times, resulting in a remainder of 488.
The next digit of our result is 8. 
Result so far: 94787.588
Deduct 6592 from 7080 and we're left with 488.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4880, and continue the process.

After the division, we end up with 94787.588 and a remainder of 0.0488.
