281154 divided by 78 
The aim is to understand the frequency of 78 in 281154.

On to step 1:
If we divide 2 by 78, we get 0 and a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Grab the next digit (8) from the dividend, add it to 2, then carry on: 28 / 78

Step 2:
78 goes into 28 0 times with a remainder of 28.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 28, we get 28.
Bring next digit (1) of the dividend behind the 28 and repeat the process: 281 / 78

On to step 3:
78 goes into 281 3 times with a remainder of 47.
Use 3 as the next digit of our solution. 
Result so far: 3.0
The remainder is 47 after subtracting 234 from 281.
Include the next digit (1) from the dividend after 47, then repeat: 471 / 78

Moving on to step 4:
When dividing 471 by 78, we get 6 with a remainder of 3.
The number 6 becomes the next digit in our result. 
Result so far: 36.0
Deduct 468 from 471 and we're left with 3.
Grab the next digit (5) from the dividend, add it to 3, then carry on: 35 / 78

Going ahead to step 5:
78 can be fit into 35 0 times, resulting in a remainder of 35.
Put 0 as the next digit of the answer. 
Result so far: 360.0
Subtracting 0 from 35 leaves us with 35.
Take the next digit (4) from the dividend and append it to 35, then repeat: 354 / 78

Step 6:
When dividing 354 by 78, we get 4 with a remainder of 42.
Use 4 as the next digit of our solution. 
Result so far: 3604.0
If we subtract 312 from 354, we get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Step 7:
420 divided by 78 is 5 with a remainder of 30.
Write down 5 as next digit of the result. 
Result so far: 3604.5
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.

Moving on to step 8:
300 divided by 78 is 3 with a remainder of 66.
Record the quotient 3 as the next digit in the result. 
Result so far: 3604.53
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 9:
660 divided by 78 is 8 with a remainder of 36.
Put 8 as the next digit of the answer. 
Result so far: 3604.538
If we subtract 624 from 660, we get 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 10:
360 divided by 78 is 4 with a remainder of 48.
Write down 4 as next digit of the result. 
Result so far: 3604.5384
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.

Advancing to step 11:
When dividing 480 by 78, we get 6 with a remainder of 12.
Record the quotient 6 as the next digit in the result. 
Result so far: 3604.53846
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 12:
When dividing 120 by 78, we get 1 with a remainder of 42.
Write down 1 as next digit of the result. 
Result so far: 3604.538461
If we subtract 78 from 120, we get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Let's proceed to step 13:
If we divide 420 by 78, we get 5 and a remainder of 30.
The number 5 becomes the next digit in our result. 
Result so far: 3604.5384615
Subtracting 390 from 420 leaves us 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.

Advancing to step 14:
78 can be fit into 300 3 times, resulting in a remainder of 66.
Record the quotient 3 as the next digit in the result. 
Result so far: 3604.53846153
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.

Our division results in 3604.53846153 with a remaining 6.6e-08.
