We're dividing 828450 by 78 
The aim is to understand the frequency of 78 in 828450.

On to step 1:
When dividing 8 by 78, we get 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Grab the next digit (2) from the dividend, add it to 8, then carry on: 82 / 78

On to step 2:
The number 78 fits into 82 1 times, leaving a remainder of 4.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 78 from 82 to get 4.
Include the next digit (8) from the dividend after 4, then repeat: 48 / 78

Moving on to step 3:
When dividing 48 by 78, we get 0 with a remainder of 48.
The next digit of our result is 0. 
Result so far: 10.0
Deduct 0 from 48 and we're left with 48.
Include the next digit (4) from the dividend after 48, then repeat: 484 / 78

Step 4:
78 can be fit into 484 6 times, resulting in a remainder of 16.
Use 6 as the next digit of our solution. 
Result so far: 106.0
Subtract 468 from 484 to get 16.
Fetch the next digit (5) from the dividend, attach it to 16 and continue: 165 / 78

Going ahead to step 5:
If we divide 165 by 78, we get 2 and a remainder of 9.
Put 2 as the next digit of the answer. 
Result so far: 1062.0
Subtract 156 from 165 to get 9.
Take the next digit (0) from the dividend and append it to 9, then repeat: 90 / 78

Let's proceed to step 6:
78 can be fit into 90 1 times, resulting in a remainder of 12.
The number 1 becomes the next digit in our result. 
Result so far: 10621.0
Deduct 78 from 90 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 7:
The number 78 fits into 120 1 times, leaving a remainder of 42.
Put 1 as the next digit of the answer. 
Result so far: 10621.1
The remainder is 42 after subtracting 78 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Step 8:
78 goes into 420 5 times with a remainder of 30.
Use 5 as the next digit of our solution. 
Result so far: 10621.15
The remainder is 30 after subtracting 390 from 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 9:
When dividing 300 by 78, we get 3 with a remainder of 66.
The number 3 becomes the next digit in our result. 
Result so far: 10621.153
The remainder is 66 after subtracting 234 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Advancing to step 10:
When dividing 660 by 78, we get 8 with a remainder of 36.
Record the quotient 8 as the next digit in the result. 
Result so far: 10621.1538
Deduct 624 from 660 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

On to step 11:
The number 78 fits into 360 4 times, leaving a remainder of 48.
Use 4 as the next digit of our solution. 
Result so far: 10621.15384
Subtract 312 from 360 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Moving on to step 12:
When dividing 480 by 78, we get 6 with a remainder of 12.
The number 6 becomes the next digit in our result. 
Result so far: 10621.153846
If we subtract 468 from 480, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 13:
78 can be fit into 120 1 times, resulting in a remainder of 42.
Put 1 as the next digit of the answer. 
Result so far: 10621.1538461
Deduct 78 from 120 and we're left with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Moving on to step 14:
420 divided by 78 is 5 with a remainder of 30.
Use 5 as the next digit of our solution. 
Result so far: 10621.15384615
Deduct 390 from 420 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

In conclusion, the division gives 10621.15384615 with a balance of 3e-08.
