249474 divided by 77 
The aim is to understand the frequency of 77 in 249474.

Moving on to step 1:
If we divide 2 by 77, we get 0 and a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Include the next digit (4) from the dividend after 2, then repeat: 24 / 77

Going ahead to step 2:
77 can be fit into 24 0 times, resulting in a remainder of 24.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 24 and we're left with 24.
Bring next digit (9) of the dividend behind the 24 and repeat the process: 249 / 77

Going ahead to step 3:
249 divided by 77 is 3 with a remainder of 18.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Subtract 231 from 249 to get 18.
Append the next digit (4) from the dividend to 18 and continue with: 184 / 77

Moving on to step 4:
184 divided by 77 is 2 with a remainder of 30.
Put 2 as the next digit of the answer. 
Result so far: 32.0
The remainder is 30 after subtracting 154 from 184.
Include the next digit (7) from the dividend after 30, then repeat: 307 / 77

Going ahead to step 5:
The number 77 fits into 307 3 times, leaving a remainder of 76.
Record the quotient 3 as the next digit in the result. 
Result so far: 323.0
If we subtract 231 from 307, we get 76.
Bring next digit (4) of the dividend behind the 76 and repeat the process: 764 / 77

Moving on to step 6:
When dividing 764 by 77, we get 9 with a remainder of 71.
Write down 9 as next digit of the result. 
Result so far: 3239.0
If we take 693 away from 764, we end up with 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

On to step 7:
77 goes into 710 9 times with a remainder of 17.
Use 9 as the next digit of our solution. 
Result so far: 3239.9
If we take 693 away from 710, we end up with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Advancing to step 8:
77 goes into 170 2 times with a remainder of 16.
The number 2 becomes the next digit in our result. 
Result so far: 3239.92
If we subtract 154 from 170, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 9:
The number 77 fits into 160 2 times, leaving a remainder of 6.
The next digit of our result is 2. 
Result so far: 3239.922
Deduct 154 from 160 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

In conclusion, the division gives 3239.922 with a balance of 0.0006.
