Let's divide 552728 by 77
The aim is to understand the frequency of 77 in 552728.

On to step 1:
The number 77 fits into 5 0 times, leaving a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Take the next digit (5) from the dividend and append it to 5, then repeat: 55 / 77

Let's proceed to step 2:
77 can be fit into 55 0 times, resulting in a remainder of 55.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 55 after subtracting 0 from 55.
Bring next digit (2) of the dividend behind the 55 and repeat the process: 552 / 77

Let's proceed to step 3:
If we divide 552 by 77, we get 7 and a remainder of 13.
Put 7 as the next digit of the answer. 
Result so far: 7.0
Subtracting 539 from 552 leaves us with 13.
Append the next digit (7) from the dividend to 13 and continue with: 137 / 77

Moving on to step 4:
77 can be fit into 137 1 times, resulting in a remainder of 60.
The next digit of our result is 1. 
Result so far: 71.0
The remainder is 60 after subtracting 77 from 137.
Take the next digit (2) from the dividend and append it to 60, then repeat: 602 / 77

On to step 5:
If we divide 602 by 77, we get 7 and a remainder of 63.
Use 7 as the next digit of our solution. 
Result so far: 717.0
Deduct 539 from 602 and we're left with 63.
Include the next digit (8) from the dividend after 63, then repeat: 638 / 77

Step 6:
77 can be fit into 638 8 times, resulting in a remainder of 22.
Put 8 as the next digit of the answer. 
Result so far: 7178.0
If we subtract 616 from 638, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 7:
When dividing 220 by 77, we get 2 with a remainder of 66.
Put 2 as the next digit of the answer. 
Result so far: 7178.2
If we take 154 away from 220, we end up with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Step 8:
When dividing 660 by 77, we get 8 with a remainder of 44.
The next digit of our result is 8. 
Result so far: 7178.28
Subtract 616 from 660 to get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Moving on to step 9:
When dividing 440 by 77, we get 5 with a remainder of 55.
Use 5 as the next digit of our solution. 
Result so far: 7178.285
Deduct 385 from 440 and we're left with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Let's proceed to step 10:
550 divided by 77 is 7 with a remainder of 11.
Use 7 as the next digit of our solution. 
Result so far: 7178.2857
Deduct 539 from 550 and we're left with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 11:
When dividing 110 by 77, we get 1 with a remainder of 33.
The next digit of our result is 1. 
Result so far: 7178.28571
If we subtract 77 from 110, we get 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Going ahead to step 12:
77 can be fit into 330 4 times, resulting in a remainder of 22.
Record the quotient 4 as the next digit in the result. 
Result so far: 7178.285714
Deduct 308 from 330 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 13:
220 divided by 77 is 2 with a remainder of 66.
The number 2 becomes the next digit in our result. 
Result so far: 7178.2857142
Subtracting 154 from 220 leaves us with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Going ahead to step 14:
660 divided by 77 is 8 with a remainder of 44.
The next digit of our result is 8. 
Result so far: 7178.28571428
Deduct 616 from 660 and we're left with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

The quotient of the division is 7178.28571428, and the remainder is 4.4e-08.
