506205 divided by 77 
The aim is to understand the frequency of 77 in 506205.

Step 1:
77 can be fit into 5 0 times, resulting in a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Fetch the next digit (0) from the dividend, attach it to 5 and continue: 50 / 77

Going ahead to step 2:
77 goes into 50 0 times with a remainder of 50.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 50 and we're left with 50.
Fetch the next digit (6) from the dividend, attach it to 50 and continue: 506 / 77

Going ahead to step 3:
77 goes into 506 6 times with a remainder of 44.
The next digit of our result is 6. 
Result so far: 6.0
Subtract 462 from 506 to get 44.
Take the next digit (2) from the dividend and append it to 44, then repeat: 442 / 77

Moving on to step 4:
If we divide 442 by 77, we get 5 and a remainder of 57.
Use 5 as the next digit of our solution. 
Result so far: 65.0
If we subtract 385 from 442, we get 57.
Append the next digit (0) from the dividend to 57 and continue with: 570 / 77

Let's proceed to step 5:
570 divided by 77 is 7 with a remainder of 31.
The next digit of our result is 7. 
Result so far: 657.0
If we subtract 539 from 570, we get 31.
Include the next digit (5) from the dividend after 31, then repeat: 315 / 77

On to step 6:
315 divided by 77 is 4 with a remainder of 7.
Use 4 as the next digit of our solution. 
Result so far: 6574.0
If we take 308 away from 315, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 7:
If we divide 70 by 77, we get 0 and a remainder of 70.
Write down 0 as next digit of the result. 
Result so far: 6574.0
Subtract 0 from 70 to get 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 8:
If we divide 700 by 77, we get 9 and a remainder of 7.
The number 9 becomes the next digit in our result. 
Result so far: 6574.09
If we subtract 693 from 700, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

On to step 9:
70 divided by 77 is 0 with a remainder of 70.
Use 0 as the next digit of our solution. 
Result so far: 6574.09
Subtracting 0 from 70 leaves us 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.

Going ahead to step 10:
The number 77 fits into 700 9 times, leaving a remainder of 7.
The next digit of our result is 9. 
Result so far: 6574.0909
The remainder is 7 after subtracting 693 from 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 11:
77 goes into 70 0 times with a remainder of 70.
Put 0 as the next digit of the answer. 
Result so far: 6574.0909
Subtract 0 from 70 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Step 12:
77 goes into 700 9 times with a remainder of 7.
Record the quotient 9 as the next digit in the result. 
Result so far: 6574.090909
If we take 693 away from 700, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

On to step 13:
77 goes into 70 0 times with a remainder of 70.
Record the quotient 0 as the next digit in the result. 
Result so far: 6574.090909
If we take 0 away from 70, 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.

Moving on to step 14:
If we divide 700 by 77, we get 9 and a remainder of 7.
The number 9 becomes the next digit in our result. 
Result so far: 6574.09090909
If we subtract 693 from 700, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Our division results in 6574.09090909 with a remaining 7e-09.
