126455 ÷ 78 
The aim is to understand the frequency of 78 in 126455.

On to step 1:
If we divide 1 by 78, we get 0 and a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 78

Let's proceed to step 2:
When dividing 12 by 78, we get 0 with a remainder of 12.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 12 after subtracting 0 from 12.
Fetch the next digit (6) from the dividend, attach it to 12 and continue: 126 / 78

Let's proceed to step 3:
126 divided by 78 is 1 with a remainder of 48.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 78 from 126 leaves us with 48.
Take the next digit (4) from the dividend and append it to 48, then repeat: 484 / 78

On to step 4:
484 divided by 78 is 6 with a remainder of 16.
Write down 6 as next digit of the result. 
Result so far: 16.0
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:
78 can be fit into 165 2 times, resulting in a remainder of 9.
The number 2 becomes the next digit in our result. 
Result so far: 162.0
Subtract 156 from 165 to get 9.
Fetch the next digit (5) from the dividend, attach it to 9 and continue: 95 / 78

Let's proceed to step 6:
The number 78 fits into 95 1 times, leaving a remainder of 17.
Put 1 as the next digit of the answer. 
Result so far: 1621.0
Subtract 78 from 95 to get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Step 7:
The number 78 fits into 170 2 times, leaving a remainder of 14.
The next digit of our result is 2. 
Result so far: 1621.2
Subtracting 156 from 170 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 8:
If we divide 140 by 78, we get 1 and a remainder of 62.
Put 1 as the next digit of the answer. 
Result so far: 1621.21
The remainder is 62 after subtracting 78 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Going ahead to step 9:
78 goes into 620 7 times with a remainder of 74.
Use 7 as the next digit of our solution. 
Result so far: 1621.217
If we take 546 away from 620, we end up with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Step 10:
740 divided by 78 is 9 with a remainder of 38.
Write down 9 as next digit of the result. 
Result so far: 1621.2179
If we take 702 away from 740, we end up 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.

Moving on to step 11:
78 can be fit into 380 4 times, resulting in a remainder of 68.
Record the quotient 4 as the next digit in the result. 
Result so far: 1621.21794
The remainder is 68 after subtracting 312 from 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Let's proceed to step 12:
The number 78 fits into 680 8 times, leaving a remainder of 56.
The number 8 becomes the next digit in our result. 
Result so far: 1621.217948
Subtract 624 from 680 to get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Going ahead to step 13:
78 can be fit into 560 7 times, resulting in a remainder of 14.
Record the quotient 7 as the next digit in the result. 
Result so far: 1621.2179487
If we subtract 546 from 560, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 14:
If we divide 140 by 78, we get 1 and a remainder of 62.
Record the quotient 1 as the next digit in the result. 
Result so far: 1621.21794871
If we subtract 78 from 140, we get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

In conclusion, the division gives 1621.21794871 with a balance of 6.2e-08.
