We divide 54657751 by 78
The aim is to understand the frequency of 78 in 54657751.

Advancing to step 1:
78 goes into 5 0 times with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Include the next digit (4) from the dividend after 5, then repeat: 54 / 78

Let's proceed to step 2:
When dividing 54 by 78, we get 0 with a remainder of 54.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 54, we end up with 54.
Bring next digit (6) of the dividend behind the 54 and repeat the process: 546 / 78

Advancing to step 3:
The number 78 fits into 546 7 times, leaving a remainder of 0.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
The remainder is 0 after subtracting 546 from 546.
Bring next digit (5) of the dividend behind the 0 and repeat the process: 5 / 78

On to step 4:
If we divide 5 by 78, we get 0 and a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 70.0
If we take 0 away from 5, we end up with 5.
Bring next digit (7) of the dividend behind the 5 and repeat the process: 57 / 78

Advancing to step 5:
78 can be fit into 57 0 times, resulting in a remainder of 57.
The number 0 becomes the next digit in our result. 
Result so far: 700.0
Deduct 0 from 57 and we're left with 57.
Include the next digit (7) from the dividend after 57, then repeat: 577 / 78

Advancing to step 6:
When dividing 577 by 78, we get 7 with a remainder of 31.
Record the quotient 7 as the next digit in the result. 
Result so far: 7007.0
If we subtract 546 from 577, we get 31.
Take the next digit (5) from the dividend and append it to 31, then repeat: 315 / 78

Step 7:
The number 78 fits into 315 4 times, leaving a remainder of 3.
Use 4 as the next digit of our solution. 
Result so far: 70074.0
If we subtract 312 from 315, we get 3.
Grab the next digit (1) from the dividend, add it to 3, then carry on: 31 / 78

Going ahead to step 8:
When dividing 31 by 78, we get 0 with a remainder of 31.
The next digit of our result is 0. 
Result so far: 700740.0
The remainder is 31 after subtracting 0 from 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 9:
The number 78 fits into 310 3 times, leaving a remainder of 76.
Put 3 as the next digit of the answer. 
Result so far: 700740.3
Subtract 234 from 310 to get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

On to step 10:
760 divided by 78 is 9 with a remainder of 58.
Put 9 as the next digit of the answer. 
Result so far: 700740.39
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.

Going ahead to step 11:
78 can be fit into 580 7 times, resulting in a remainder of 34.
Put 7 as the next digit of the answer. 
Result so far: 700740.397
The remainder is 34 after subtracting 546 from 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Moving on to step 12:
78 goes into 340 4 times with a remainder of 28.
Write down 4 as next digit of the result. 
Result so far: 700740.3974
If we take 312 away from 340, we end up 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.

Let's proceed to step 13:
If we divide 280 by 78, we get 3 and a remainder of 46.
The next digit of our result is 3. 
Result so far: 700740.39743
Subtracting 234 from 280 leaves us with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

On to step 14:
460 divided by 78 is 5 with a remainder of 70.
The next digit of our result is 5. 
Result so far: 700740.397435
If we take 390 away from 460, we end up 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.

Advancing to step 15:
The number 78 fits into 700 8 times, leaving a remainder of 76.
Use 8 as the next digit of our solution. 
Result so far: 700740.3974358
Subtract 624 from 700 to get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

On to step 16:
If we divide 760 by 78, we get 9 and a remainder of 58.
Record the quotient 9 as the next digit in the result. 
Result so far: 700740.39743589
If we subtract 702 from 760, we 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.

In conclusion, the division gives 700740.39743589 with a balance of 5.8e-08.
