We look at the division of 557103 by 77 
The aim is to understand the frequency of 77 in 557103.

Moving on to step 1:
77 goes into 5 0 times with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Include the next digit (5) from the dividend after 5, then repeat: 55 / 77

Step 2:
The number 77 fits into 55 0 times, leaving a remainder of 55.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 55, we end up with 55.
Bring next digit (7) of the dividend behind the 55 and repeat the process: 557 / 77

Going ahead to step 3:
The number 77 fits into 557 7 times, leaving a remainder of 18.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
Subtract 539 from 557 to get 18.
Take the next digit (1) from the dividend and append it to 18, then repeat: 181 / 77

Going ahead to step 4:
77 goes into 181 2 times with a remainder of 27.
Put 2 as the next digit of the answer. 
Result so far: 72.0
Subtracting 154 from 181 leaves us with 27.
Grab the next digit (0) from the dividend, add it to 27, then carry on: 270 / 77

Advancing to step 5:
77 goes into 270 3 times with a remainder of 39.
The number 3 becomes the next digit in our result. 
Result so far: 723.0
Subtract 231 from 270 to get 39.
Include the next digit (3) from the dividend after 39, then repeat: 393 / 77

Let's proceed to step 6:
The number 77 fits into 393 5 times, leaving a remainder of 8.
Use 5 as the next digit of our solution. 
Result so far: 7235.0
If we take 385 away from 393, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 7:
If we divide 80 by 77, we get 1 and a remainder of 3.
Use 1 as the next digit of our solution. 
Result so far: 7235.1
If we take 77 away from 80, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 8:
If we divide 30 by 77, we get 0 and a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 7235.1
If we take 0 away from 30, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 9:
When dividing 300 by 77, we get 3 with a remainder of 69.
The next digit of our result is 3. 
Result so far: 7235.103
If we take 231 away from 300, we end up with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Let's proceed to step 10:
77 goes into 690 8 times with a remainder of 74.
Record the quotient 8 as the next digit in the result. 
Result so far: 7235.1038
Deduct 616 from 690 and we're left with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

On to step 11:
When dividing 740 by 77, we get 9 with a remainder of 47.
Use 9 as the next digit of our solution. 
Result so far: 7235.10389
If we subtract 693 from 740, we get 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Advancing to step 12:
77 goes into 470 6 times with a remainder of 8.
The number 6 becomes the next digit in our result. 
Result so far: 7235.103896
Deduct 462 from 470 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 13:
77 goes into 80 1 times with a remainder of 3.
The number 1 becomes the next digit in our result. 
Result so far: 7235.1038961
Deduct 77 from 80 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 14:
30 divided by 77 is 0 with a remainder of 30.
The next digit of our result is 0. 
Result so far: 7235.1038961
Deduct 0 from 30 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

The quotient of the division is 7235.1038961, and the remainder is 3e-08.
