545523 divided by 77 
The aim is to understand the frequency of 77 in 545523.

Going ahead to step 1:
5 divided by 77 is 0 with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Fetch the next digit (4) from the dividend, attach it to 5 and continue: 54 / 77

Let's proceed to step 2:
77 goes into 54 0 times with a remainder of 54.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 54, we get 54.
Take the next digit (5) from the dividend and append it to 54, then repeat: 545 / 77

On to step 3:
545 divided by 77 is 7 with a remainder of 6.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
Deduct 539 from 545 and we're left with 6.
Grab the next digit (5) from the dividend, add it to 6, then carry on: 65 / 77

Moving on to step 4:
If we divide 65 by 77, we get 0 and a remainder of 65.
The next digit of our result is 0. 
Result so far: 70.0
The remainder is 65 after subtracting 0 from 65.
Grab the next digit (2) from the dividend, add it to 65, then carry on: 652 / 77

Advancing to step 5:
The number 77 fits into 652 8 times, leaving a remainder of 36.
The number 8 becomes the next digit in our result. 
Result so far: 708.0
Subtracting 616 from 652 leaves us with 36.
Bring next digit (3) of the dividend behind the 36 and repeat the process: 363 / 77

Moving on to step 6:
77 goes into 363 4 times with a remainder of 55.
The number 4 becomes the next digit in our result. 
Result so far: 7084.0
If we take 308 away from 363, we end up 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 7:
550 divided by 77 is 7 with a remainder of 11.
Record the quotient 7 as the next digit in the result. 
Result so far: 7084.7
The remainder is 11 after subtracting 539 from 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 8:
110 divided by 77 is 1 with a remainder of 33.
The next digit of our result is 1. 
Result so far: 7084.71
Subtract 77 from 110 to 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.

Let's proceed to step 9:
If we divide 330 by 77, we get 4 and a remainder of 22.
The next digit of our result is 4. 
Result so far: 7084.714
Subtract 308 from 330 to 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.

Going ahead to step 10:
220 divided by 77 is 2 with a remainder of 66.
Record the quotient 2 as the next digit in the result. 
Result so far: 7084.7142
If we subtract 154 from 220, we get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

On to step 11:
77 can be fit into 660 8 times, resulting in a remainder of 44.
The next digit of our result is 8. 
Result so far: 7084.71428
The remainder is 44 after subtracting 616 from 660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Going ahead to step 12:
If we divide 440 by 77, we get 5 and a remainder of 55.
Write down 5 as next digit of the result. 
Result so far: 7084.714285
Subtracting 385 from 440 leaves us 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.

Going ahead to step 13:
77 goes into 550 7 times with a remainder of 11.
Use 7 as the next digit of our solution. 
Result so far: 7084.7142857
Subtracting 539 from 550 leaves us 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.

Going ahead to step 14:
When dividing 110 by 77, we get 1 with a remainder of 33.
The next digit of our result is 1. 
Result so far: 7084.71428571
Subtract 77 from 110 to 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.

The quotient of the division is 7084.71428571, and the remainder is 3.3e-08.
