806477 ÷ 78 
The aim is to understand the frequency of 78 in 806477.

Advancing to step 1:
78 goes into 8 0 times with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Include the next digit (0) from the dividend after 8, then repeat: 80 / 78

Going ahead to step 2:
80 divided by 78 is 1 with a remainder of 2.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 78 from 80 to get 2.
Fetch the next digit (6) from the dividend, attach it to 2 and continue: 26 / 78

On to step 3:
78 can be fit into 26 0 times, resulting in a remainder of 26.
The next digit of our result is 0. 
Result so far: 10.0
If we subtract 0 from 26, we get 26.
Grab the next digit (4) from the dividend, add it to 26, then carry on: 264 / 78

On to step 4:
264 divided by 78 is 3 with a remainder of 30.
Use 3 as the next digit of our solution. 
Result so far: 103.0
Deduct 234 from 264 and we're left with 30.
Include the next digit (7) from the dividend after 30, then repeat: 307 / 78

Let's proceed to step 5:
307 divided by 78 is 3 with a remainder of 73.
The number 3 becomes the next digit in our result. 
Result so far: 1033.0
Subtract 234 from 307 to get 73.
Bring next digit (7) of the dividend behind the 73 and repeat the process: 737 / 78

Advancing to step 6:
The number 78 fits into 737 9 times, leaving a remainder of 35.
Use 9 as the next digit of our solution. 
Result so far: 10339.0
If we take 702 away from 737, we end up with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Going ahead to step 7:
When dividing 350 by 78, we get 4 with a remainder of 38.
The number 4 becomes the next digit in our result. 
Result so far: 10339.4
Deduct 312 from 350 and we're left with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Advancing to step 8:
380 divided by 78 is 4 with a remainder of 68.
Use 4 as the next digit of our solution. 
Result so far: 10339.44
Subtracting 312 from 380 leaves us with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Our division results in 10339.44 with a remaining 0.068.
