We're dividing 250555 by 77 
The aim is to understand the frequency of 77 in 250555.

Let's proceed to step 1:
When dividing 2 by 77, we get 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Include the next digit (5) from the dividend after 2, then repeat: 25 / 77

Let's proceed to step 2:
77 can be fit into 25 0 times, resulting in a remainder of 25.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 25 leaves us with 25.
Append the next digit (0) from the dividend to 25 and continue with: 250 / 77

On to step 3:
When dividing 250 by 77, we get 3 with a remainder of 19.
Write down 3 as next digit of the result. 
Result so far: 3.0
Subtract 231 from 250 to get 19.
Take the next digit (5) from the dividend and append it to 19, then repeat: 195 / 77

Advancing to step 4:
When dividing 195 by 77, we get 2 with a remainder of 41.
Write down 2 as next digit of the result. 
Result so far: 32.0
Deduct 154 from 195 and we're left with 41.
Grab the next digit (5) from the dividend, add it to 41, then carry on: 415 / 77

Let's proceed to step 5:
The number 77 fits into 415 5 times, leaving a remainder of 30.
Record the quotient 5 as the next digit in the result. 
Result so far: 325.0
Subtracting 385 from 415 leaves us with 30.
Include the next digit (5) from the dividend after 30, then repeat: 305 / 77

Step 6:
77 can be fit into 305 3 times, resulting in a remainder of 74.
Record the quotient 3 as the next digit in the result. 
Result so far: 3253.0
Subtracting 231 from 305 leaves us with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Advancing to step 7:
When dividing 740 by 77, we get 9 with a remainder of 47.
The next digit of our result is 9. 
Result so far: 3253.9
The remainder is 47 after subtracting 693 from 740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

On to step 8:
If we divide 470 by 77, we get 6 and a remainder of 8.
The number 6 becomes the next digit in our result. 
Result so far: 3253.96
If we subtract 462 from 470, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 9:
When dividing 80 by 77, we get 1 with a remainder of 3.
Use 1 as the next digit of our solution. 
Result so far: 3253.961
If we subtract 77 from 80, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 10:
If we divide 30 by 77, we get 0 and a remainder of 30.
The next digit of our result is 0. 
Result so far: 3253.961
The remainder is 30 after subtracting 0 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 11:
77 can be fit into 300 3 times, resulting in a remainder of 69.
Write down 3 as next digit of the result. 
Result so far: 3253.96103
If we subtract 231 from 300, we get 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Step 12:
690 divided by 77 is 8 with a remainder of 74.
The next digit of our result is 8. 
Result so far: 3253.961038
The remainder is 74 after subtracting 616 from 690.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

On to step 13:
740 divided by 77 is 9 with a remainder of 47.
Use 9 as the next digit of our solution. 
Result so far: 3253.9610389
The remainder is 47 after subtracting 693 from 740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Moving on to step 14:
77 goes into 470 6 times with a remainder of 8.
Record the quotient 6 as the next digit in the result. 
Result so far: 3253.96103896
Subtract 462 from 470 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

After the division, we end up with 3253.96103896 and a remainder of 8e-09.
