608413 divided by 77 
The aim is to understand the frequency of 77 in 608413.

Moving on to step 1:
6 divided by 77 is 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Bring next digit (0) of the dividend behind the 6 and repeat the process: 60 / 77

Going ahead to step 2:
77 goes into 60 0 times with a remainder of 60.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 60 and we're left with 60.
Take the next digit (8) from the dividend and append it to 60, then repeat: 608 / 77

Step 3:
77 goes into 608 7 times with a remainder of 69.
Use 7 as the next digit of our solution. 
Result so far: 7.0
Subtracting 539 from 608 leaves us with 69.
Append the next digit (4) from the dividend to 69 and continue with: 694 / 77

Going ahead to step 4:
77 can be fit into 694 9 times, resulting in a remainder of 1.
Use 9 as the next digit of our solution. 
Result so far: 79.0
The remainder is 1 after subtracting 693 from 694.
Append the next digit (1) from the dividend to 1 and continue with: 11 / 77

Step 5:
When dividing 11 by 77, we get 0 with a remainder of 11.
The next digit of our result is 0. 
Result so far: 790.0
The remainder is 11 after subtracting 0 from 11.
Bring next digit (3) of the dividend behind the 11 and repeat the process: 113 / 77

Step 6:
77 can be fit into 113 1 times, resulting in a remainder of 36.
Put 1 as the next digit of the answer. 
Result so far: 7901.0
If we take 77 away from 113, we end up with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Let's proceed to step 7:
The number 77 fits into 360 4 times, leaving a remainder of 52.
The next digit of our result is 4. 
Result so far: 7901.4
Subtracting 308 from 360 leaves us with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Moving on to step 8:
When dividing 520 by 77, we get 6 with a remainder of 58.
Write down 6 as next digit of the result. 
Result so far: 7901.46
The remainder is 58 after subtracting 462 from 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Step 9:
The number 77 fits into 580 7 times, leaving a remainder of 41.
Use 7 as the next digit of our solution. 
Result so far: 7901.467
The remainder is 41 after subtracting 539 from 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Step 10:
77 goes into 410 5 times with a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 7901.4675
If we subtract 385 from 410, we get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Let's proceed to step 11:
77 goes into 250 3 times with a remainder of 19.
The number 3 becomes the next digit in our result. 
Result so far: 7901.46753
Subtracting 231 from 250 leaves us with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Advancing to step 12:
77 can be fit into 190 2 times, resulting in a remainder of 36.
Write down 2 as next digit of the result. 
Result so far: 7901.467532
If we subtract 154 from 190, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

On to step 13:
When dividing 360 by 77, we get 4 with a remainder of 52.
The number 4 becomes the next digit in our result. 
Result so far: 7901.4675324
The remainder is 52 after subtracting 308 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Step 14:
When dividing 520 by 77, we get 6 with a remainder of 58.
Record the quotient 6 as the next digit in the result. 
Result so far: 7901.46753246
Subtract 462 from 520 to 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.

After the division, we end up with 7901.46753246 and a remainder of 5.8e-08.
