We're dividing 276697 by 78 
The aim is to understand the frequency of 78 in 276697.

Going ahead to step 1:
78 can be fit into 2 0 times, resulting in a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Grab the next digit (7) from the dividend, add it to 2, then carry on: 27 / 78

On to step 2:
27 divided by 78 is 0 with a remainder of 27.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 27, we end up with 27.
Append the next digit (6) from the dividend to 27 and continue with: 276 / 78

Moving on to step 3:
If we divide 276 by 78, we get 3 and a remainder of 42.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Subtracting 234 from 276 leaves us with 42.
Append the next digit (6) from the dividend to 42 and continue with: 426 / 78

Step 4:
If we divide 426 by 78, we get 5 and a remainder of 36.
Use 5 as the next digit of our solution. 
Result so far: 35.0
Subtract 390 from 426 to get 36.
Append the next digit (9) from the dividend to 36 and continue with: 369 / 78

Step 5:
If we divide 369 by 78, we get 4 and a remainder of 57.
Use 4 as the next digit of our solution. 
Result so far: 354.0
If we subtract 312 from 369, we get 57.
Bring next digit (7) of the dividend behind the 57 and repeat the process: 577 / 78

Going ahead to step 6:
If we divide 577 by 78, we get 7 and a remainder of 31.
The next digit of our result is 7. 
Result so far: 3547.0
If we subtract 546 from 577, we get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Advancing to step 7:
When dividing 310 by 78, we get 3 with a remainder of 76.
Use 3 as the next digit of our solution. 
Result so far: 3547.3
Deduct 234 from 310 and we're left 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.

Let's proceed to step 8:
When dividing 760 by 78, we get 9 with a remainder of 58.
Use 9 as the next digit of our solution. 
Result so far: 3547.39
Subtracting 702 from 760 leaves us with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Advancing to step 9:
The number 78 fits into 580 7 times, leaving a remainder of 34.
Use 7 as the next digit of our solution. 
Result so far: 3547.397
Subtracting 546 from 580 leaves us with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Going ahead to step 10:
If we divide 340 by 78, we get 4 and a remainder of 28.
Record the quotient 4 as the next digit in the result. 
Result so far: 3547.3974
Subtract 312 from 340 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 11:
If we divide 280 by 78, we get 3 and a remainder of 46.
Write down 3 as next digit of the result. 
Result so far: 3547.39743
If we subtract 234 from 280, we get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Step 12:
If we divide 460 by 78, we get 5 and a remainder of 70.
Record the quotient 5 as the next digit in the result. 
Result so far: 3547.397435
Subtract 390 from 460 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

On to step 13:
The number 78 fits into 700 8 times, leaving a remainder of 76.
The number 8 becomes the next digit in our result. 
Result so far: 3547.3974358
The remainder is 76 after subtracting 624 from 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Let's proceed to step 14:
78 goes into 760 9 times with a remainder of 58.
The next digit of our result is 9. 
Result so far: 3547.39743589
Subtract 702 from 760 to get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

The quotient of the division is 3547.39743589, and the remainder is 5.8e-08.
