We look at the division of 452665 by 78 
The aim is to understand the frequency of 78 in 452665.

Let's proceed to step 1:
78 can be fit into 4 0 times, resulting in a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Take the next digit (5) from the dividend and append it to 4, then repeat: 45 / 78

Let's proceed to step 2:
78 can be fit into 45 0 times, resulting in a remainder of 45.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 45 after subtracting 0 from 45.
Grab the next digit (2) from the dividend, add it to 45, then carry on: 452 / 78

Let's proceed to step 3:
If we divide 452 by 78, we get 5 and a remainder of 62.
Use 5 as the next digit of our solution. 
Result so far: 5.0
Subtracting 390 from 452 leaves us with 62.
Append the next digit (6) from the dividend to 62 and continue with: 626 / 78

Moving on to step 4:
The number 78 fits into 626 8 times, leaving a remainder of 2.
Use 8 as the next digit of our solution. 
Result so far: 58.0
Subtract 624 from 626 to get 2.
Bring next digit (6) of the dividend behind the 2 and repeat the process: 26 / 78

On to step 5:
If we divide 26 by 78, we get 0 and a remainder of 26.
Write down 0 as next digit of the result. 
Result so far: 580.0
Subtracting 0 from 26 leaves us with 26.
Append the next digit (5) from the dividend to 26 and continue with: 265 / 78

On to step 6:
The number 78 fits into 265 3 times, leaving a remainder of 31.
Put 3 as the next digit of the answer. 
Result so far: 5803.0
Subtract 234 from 265 to 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:
310 divided by 78 is 3 with a remainder of 76.
Use 3 as the next digit of our solution. 
Result so far: 5803.3
Subtracting 234 from 310 leaves us 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.

Advancing to step 8:
78 can be fit into 760 9 times, resulting in a remainder of 58.
Write down 9 as next digit of the result. 
Result so far: 5803.39
Deduct 702 from 760 and we're left 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.

Moving on to step 9:
If we divide 580 by 78, we get 7 and a remainder of 34.
The number 7 becomes the next digit in our result. 
Result so far: 5803.397
Deduct 546 from 580 and we're left 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.

Advancing to step 10:
When dividing 340 by 78, we get 4 with a remainder of 28.
Use 4 as the next digit of our solution. 
Result so far: 5803.3974
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.

Going ahead to step 11:
The number 78 fits into 280 3 times, leaving a remainder of 46.
Put 3 as the next digit of the answer. 
Result so far: 5803.39743
The remainder is 46 after subtracting 234 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Moving on to step 12:
78 goes into 460 5 times with a remainder of 70.
Write down 5 as next digit of the result. 
Result so far: 5803.397435
Subtracting 390 from 460 leaves us 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.

On to step 13:
78 goes into 700 8 times with a remainder of 76.
Put 8 as the next digit of the answer. 
Result so far: 5803.3974358
Subtracting 624 from 700 leaves us 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.

Advancing to step 14:
760 divided by 78 is 9 with a remainder of 58.
Record the quotient 9 as the next digit in the result. 
Result so far: 5803.39743589
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.

The final result is 5803.39743589 with a remainder of 5.8e-08.
