256147 ÷ 78 
The aim is to understand the frequency of 78 in 256147.

On to step 1:
If we divide 2 by 78, we get 0 and a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Take the next digit (5) from the dividend and append it to 2, then repeat: 25 / 78

On to step 2:
The number 78 fits into 25 0 times, leaving a remainder of 25.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 25 after subtracting 0 from 25.
Fetch the next digit (6) from the dividend, attach it to 25 and continue: 256 / 78

Let's proceed to step 3:
78 can be fit into 256 3 times, resulting in a remainder of 22.
Write down 3 as next digit of the result. 
Result so far: 3.0
If we take 234 away from 256, we end up with 22.
Fetch the next digit (1) from the dividend, attach it to 22 and continue: 221 / 78

Let's proceed to step 4:
When dividing 221 by 78, we get 2 with a remainder of 65.
Write down 2 as next digit of the result. 
Result so far: 32.0
Deduct 156 from 221 and we're left with 65.
Bring next digit (4) of the dividend behind the 65 and repeat the process: 654 / 78

Let's proceed to step 5:
If we divide 654 by 78, we get 8 and a remainder of 30.
The next digit of our result is 8. 
Result so far: 328.0
The remainder is 30 after subtracting 624 from 654.
Fetch the next digit (7) from the dividend, attach it to 30 and continue: 307 / 78

Going ahead to step 6:
78 can be fit into 307 3 times, resulting in a remainder of 73.
The next digit of our result is 3. 
Result so far: 3283.0
The remainder is 73 after subtracting 234 from 307.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Step 7:
78 can be fit into 730 9 times, resulting in a remainder of 28.
The number 9 becomes the next digit in our result. 
Result so far: 3283.9
If we take 702 away from 730, we end up with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

On to step 8:
280 divided by 78 is 3 with a remainder of 46.
Record the quotient 3 as the next digit in the result. 
Result so far: 3283.93
Subtracting 234 from 280 leaves us with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

On to step 9:
The number 78 fits into 460 5 times, leaving a remainder of 70.
Put 5 as the next digit of the answer. 
Result so far: 3283.935
Deduct 390 from 460 and we're left with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Step 10:
700 divided by 78 is 8 with a remainder of 76.
Record the quotient 8 as the next digit in the result. 
Result so far: 3283.9358
If we take 624 away from 700, we end up with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Step 11:
78 goes into 760 9 times with a remainder of 58.
Write down 9 as next digit of the result. 
Result so far: 3283.93589
The remainder is 58 after subtracting 702 from 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

On to step 12:
78 can be fit into 580 7 times, resulting in a remainder of 34.
Record the quotient 7 as the next digit in the result. 
Result so far: 3283.935897
If we subtract 546 from 580, we get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Let's proceed to step 13:
78 goes into 340 4 times with a remainder of 28.
Write down 4 as next digit of the result. 
Result so far: 3283.9358974
The remainder is 28 after subtracting 312 from 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Step 14:
280 divided by 78 is 3 with a remainder of 46.
Use 3 as the next digit of our solution. 
Result so far: 3283.93589743
If we take 234 away from 280, we end up with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

The final outcome is 3283.93589743, with a leftover of 4.6e-08.
