We're dividing 999518 by 77 
The aim is to understand the frequency of 77 in 999518.

Moving on to step 1:
77 can be fit into 9 0 times, resulting in a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Include the next digit (9) from the dividend after 9, then repeat: 99 / 77

On to step 2:
77 goes into 99 1 times with a remainder of 22.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 77 from 99 leaves us with 22.
Grab the next digit (9) from the dividend, add it to 22, then carry on: 229 / 77

Moving on to step 3:
77 can be fit into 229 2 times, resulting in a remainder of 75.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
Deduct 154 from 229 and we're left with 75.
Bring next digit (5) of the dividend behind the 75 and repeat the process: 755 / 77

Moving on to step 4:
77 goes into 755 9 times with a remainder of 62.
Use 9 as the next digit of our solution. 
Result so far: 129.0
Subtracting 693 from 755 leaves us with 62.
Bring next digit (1) of the dividend behind the 62 and repeat the process: 621 / 77

Going ahead to step 5:
77 goes into 621 8 times with a remainder of 5.
The next digit of our result is 8. 
Result so far: 1298.0
Subtracting 616 from 621 leaves us with 5.
Append the next digit (8) from the dividend to 5 and continue with: 58 / 77

Going ahead to step 6:
The number 77 fits into 58 0 times, leaving a remainder of 58.
Record the quotient 0 as the next digit in the result. 
Result so far: 12980.0
Subtracting 0 from 58 leaves us with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Advancing to step 7:
If we divide 580 by 77, we get 7 and a remainder of 41.
Put 7 as the next digit of the answer. 
Result so far: 12980.7
Subtract 539 from 580 to get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Moving on to step 8:
77 goes into 410 5 times with a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 12980.75
Deduct 385 from 410 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Step 9:
The number 77 fits into 250 3 times, leaving a remainder of 19.
Put 3 as the next digit of the answer. 
Result so far: 12980.753
If we subtract 231 from 250, we get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Going ahead to step 10:
77 goes into 190 2 times with a remainder of 36.
The number 2 becomes the next digit in our result. 
Result so far: 12980.7532
If we take 154 away from 190, 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.

Step 11:
77 can be fit into 360 4 times, resulting in a remainder of 52.
Put 4 as the next digit of the answer. 
Result so far: 12980.75324
Subtract 308 from 360 to get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Step 12:
77 can be fit into 520 6 times, resulting in a remainder of 58.
The number 6 becomes the next digit in our result. 
Result so far: 12980.753246
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.

On to step 13:
When dividing 580 by 77, we get 7 with a remainder of 41.
Use 7 as the next digit of our solution. 
Result so far: 12980.7532467
Subtract 539 from 580 to get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Moving on to step 14:
410 divided by 77 is 5 with a remainder of 25.
Put 5 as the next digit of the answer. 
Result so far: 12980.75324675
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.

In conclusion, the division gives 12980.75324675 with a balance of 2.5e-08.
