552853 ÷ 78 
The aim is to understand the frequency of 78 in 552853.

On to step 1:
5 divided by 78 is 0 with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Append the next digit (5) from the dividend to 5 and continue with: 55 / 78

Going ahead to step 2:
55 divided by 78 is 0 with a remainder of 55.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 55 to get 55.
Grab the next digit (2) from the dividend, add it to 55, then carry on: 552 / 78

Moving on to step 3:
The number 78 fits into 552 7 times, leaving a remainder of 6.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
Subtracting 546 from 552 leaves us with 6.
Append the next digit (8) from the dividend to 6 and continue with: 68 / 78

Let's proceed to step 4:
The number 78 fits into 68 0 times, leaving a remainder of 68.
Use 0 as the next digit of our solution. 
Result so far: 70.0
Subtracting 0 from 68 leaves us with 68.
Bring next digit (5) of the dividend behind the 68 and repeat the process: 685 / 78

Going ahead to step 5:
If we divide 685 by 78, we get 8 and a remainder of 61.
Write down 8 as next digit of the result. 
Result so far: 708.0
Deduct 624 from 685 and we're left with 61.
Take the next digit (3) from the dividend and append it to 61, then repeat: 613 / 78

Advancing to step 6:
78 goes into 613 7 times with a remainder of 67.
Put 7 as the next digit of the answer. 
Result so far: 7087.0
Subtract 546 from 613 to get 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Step 7:
If we divide 670 by 78, we get 8 and a remainder of 46.
The number 8 becomes the next digit in our result. 
Result so far: 7087.8
Subtract 624 from 670 to 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.

Going ahead to step 8:
78 can be fit into 460 5 times, resulting in a remainder of 70.
The number 5 becomes the next digit in our result. 
Result so far: 7087.85
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.

On to step 9:
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: 7087.858
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.

Going ahead to step 10:
78 can be fit into 760 9 times, resulting in a remainder of 58.
The number 9 becomes the next digit in our result. 
Result so far: 7087.8589
If we take 702 away from 760, we end up 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.

Step 11:
When dividing 580 by 78, we get 7 with a remainder of 34.
Put 7 as the next digit of the answer. 
Result so far: 7087.85897
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.

Let's proceed to step 12:
The number 78 fits into 340 4 times, leaving a remainder of 28.
The next digit of our result is 4. 
Result so far: 7087.858974
Deduct 312 from 340 and we're left 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.

Going ahead to step 13:
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: 7087.8589743
Subtract 234 from 280 to 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.

Moving on to step 14:
78 goes into 460 5 times with a remainder of 70.
The next digit of our result is 5. 
Result so far: 7087.85897435
The remainder is 70 after subtracting 390 from 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Our division results in 7087.85897435 with a remaining 7e-08.
