We're dividing 860064 by 78 
The aim is to understand the frequency of 78 in 860064.

On to step 1:
The number 78 fits into 8 0 times, leaving a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Grab the next digit (6) from the dividend, add it to 8, then carry on: 86 / 78

Moving on to step 2:
86 divided by 78 is 1 with a remainder of 8.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 78 from 86 and we're left with 8.
Append the next digit (0) from the dividend to 8 and continue with: 80 / 78

Let's proceed to step 3:
When dividing 80 by 78, we get 1 with a remainder of 2.
Use 1 as the next digit of our solution. 
Result so far: 11.0
Deduct 78 from 80 and we're left with 2.
Take the next digit (0) from the dividend and append it to 2, then repeat: 20 / 78

Moving on to step 4:
78 goes into 20 0 times with a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 110.0
If we subtract 0 from 20, we get 20.
Bring next digit (6) of the dividend behind the 20 and repeat the process: 206 / 78

On to step 5:
78 can be fit into 206 2 times, resulting in a remainder of 50.
Record the quotient 2 as the next digit in the result. 
Result so far: 1102.0
If we take 156 away from 206, we end up with 50.
Append the next digit (4) from the dividend to 50 and continue with: 504 / 78

On to step 6:
78 goes into 504 6 times with a remainder of 36.
Put 6 as the next digit of the answer. 
Result so far: 11026.0
Subtracting 468 from 504 leaves us 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.

Step 7:
The number 78 fits into 360 4 times, leaving a remainder of 48.
The number 4 becomes the next digit in our result. 
Result so far: 11026.4
If we take 312 away from 360, we end up 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 8:
If we divide 480 by 78, we get 6 and a remainder of 12.
Write down 6 as next digit of the result. 
Result so far: 11026.46
Subtracting 468 from 480 leaves us 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 9:
If we divide 120 by 78, we get 1 and a remainder of 42.
Use 1 as the next digit of our solution. 
Result so far: 11026.461
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 10:
If we divide 420 by 78, we get 5 and a remainder of 30.
Record the quotient 5 as the next digit in the result. 
Result so far: 11026.4615
If we subtract 390 from 420, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 11:
78 can be fit into 300 3 times, resulting in a remainder of 66.
The next digit of our result is 3. 
Result so far: 11026.46153
If we take 234 away from 300, we end up with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Let's proceed to step 12:
When dividing 660 by 78, we get 8 with a remainder of 36.
Use 8 as the next digit of our solution. 
Result so far: 11026.461538
If we take 624 away from 660, we end up 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.

Going ahead to step 13:
360 divided by 78 is 4 with a remainder of 48.
Put 4 as the next digit of the answer. 
Result so far: 11026.4615384
If we subtract 312 from 360, we 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.

On to step 14:
When dividing 480 by 78, we get 6 with a remainder of 12.
Put 6 as the next digit of the answer. 
Result so far: 11026.46153846
If we take 468 away from 480, we end up 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.

The quotient of the division is 11026.46153846, and the remainder is 1.2e-08.
