293857 divided by 77 
The aim is to understand the frequency of 77 in 293857.

Advancing to step 1:
77 goes into 2 0 times with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Include the next digit (9) from the dividend after 2, then repeat: 29 / 77

Step 2:
If we divide 29 by 77, we get 0 and a remainder of 29.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 29, we get 29.
Grab the next digit (3) from the dividend, add it to 29, then carry on: 293 / 77

Moving on to step 3:
77 can be fit into 293 3 times, resulting in a remainder of 62.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we take 231 away from 293, we end up with 62.
Grab the next digit (8) from the dividend, add it to 62, then carry on: 628 / 77

Advancing to step 4:
When dividing 628 by 77, we get 8 with a remainder of 12.
The number 8 becomes the next digit in our result. 
Result so far: 38.0
If we take 616 away from 628, we end up with 12.
Bring next digit (5) of the dividend behind the 12 and repeat the process: 125 / 77

Let's proceed to step 5:
When dividing 125 by 77, we get 1 with a remainder of 48.
Write down 1 as next digit of the result. 
Result so far: 381.0
The remainder is 48 after subtracting 77 from 125.
Append the next digit (7) from the dividend to 48 and continue with: 487 / 77

Moving on to step 6:
77 goes into 487 6 times with a remainder of 25.
The number 6 becomes the next digit in our result. 
Result so far: 3816.0
If we take 462 away from 487, we end up 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.

Moving on to step 7:
When dividing 250 by 77, we get 3 with a remainder of 19.
Use 3 as the next digit of our solution. 
Result so far: 3816.3
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.

Step 8:
77 goes into 190 2 times with a remainder of 36.
Write down 2 as next digit of the result. 
Result so far: 3816.32
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 9:
When dividing 360 by 77, we get 4 with a remainder of 52.
The next digit of our result is 4. 
Result so far: 3816.324
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 10:
When dividing 520 by 77, we get 6 with a remainder of 58.
The number 6 becomes the next digit in our result. 
Result so far: 3816.3246
If we subtract 462 from 520, we 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.

On to step 11:
580 divided by 77 is 7 with a remainder of 41.
Put 7 as the next digit of the answer. 
Result so far: 3816.32467
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 12:
The number 77 fits into 410 5 times, leaving a remainder of 25.
Record the quotient 5 as the next digit in the result. 
Result so far: 3816.324675
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 13:
The number 77 fits into 250 3 times, leaving a remainder of 19.
Use 3 as the next digit of our solution. 
Result so far: 3816.3246753
Deduct 231 from 250 and we're left 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.

Going ahead to step 14:
If we divide 190 by 77, we get 2 and a remainder of 36.
Put 2 as the next digit of the answer. 
Result so far: 3816.32467532
The remainder is 36 after subtracting 154 from 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

The final outcome is 3816.32467532, with a leftover of 3.6e-08.
