We're dividing 325515 by 77 
The aim is to understand the frequency of 77 in 325515.

Moving on to step 1:
If we divide 3 by 77, we get 0 and a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Fetch the next digit (2) from the dividend, attach it to 3 and continue: 32 / 77

Let's proceed to step 2:
77 can be fit into 32 0 times, resulting in a remainder of 32.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 32 to get 32.
Take the next digit (5) from the dividend and append it to 32, then repeat: 325 / 77

Moving on to step 3:
If we divide 325 by 77, we get 4 and a remainder of 17.
Write down 4 as next digit of the result. 
Result so far: 4.0
If we subtract 308 from 325, we get 17.
Take the next digit (5) from the dividend and append it to 17, then repeat: 175 / 77

On to step 4:
When dividing 175 by 77, we get 2 with a remainder of 21.
Write down 2 as next digit of the result. 
Result so far: 42.0
Subtract 154 from 175 to get 21.
Include the next digit (1) from the dividend after 21, then repeat: 211 / 77

Going ahead to step 5:
The number 77 fits into 211 2 times, leaving a remainder of 57.
Use 2 as the next digit of our solution. 
Result so far: 422.0
If we take 154 away from 211, we end up with 57.
Include the next digit (5) from the dividend after 57, then repeat: 575 / 77

Going ahead to step 6:
The number 77 fits into 575 7 times, leaving a remainder of 36.
Use 7 as the next digit of our solution. 
Result so far: 4227.0
If we take 539 away from 575, 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.

Moving on to step 7:
If we divide 360 by 77, we get 4 and a remainder of 52.
Put 4 as the next digit of the answer. 
Result so far: 4227.4
If we take 308 away from 360, we end up 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.

Step 8:
77 can be fit into 520 6 times, resulting in a remainder of 58.
Write down 6 as next digit of the result. 
Result so far: 4227.46
If we take 462 away from 520, we end up 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.

Moving on to step 9:
When dividing 580 by 77, we get 7 with a remainder of 41.
Write down 7 as next digit of the result. 
Result so far: 4227.467
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.

Going ahead to step 10:
If we divide 410 by 77, we get 5 and a remainder of 25.
The next digit of our result is 5. 
Result so far: 4227.4675
If we take 385 away from 410, 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.

Going ahead to step 11:
77 goes into 250 3 times with a remainder of 19.
Write down 3 as next digit of the result. 
Result so far: 4227.46753
The remainder is 19 after subtracting 231 from 250.
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:
If we divide 190 by 77, we get 2 and a remainder of 36.
Record the quotient 2 as the next digit in the result. 
Result so far: 4227.467532
Deduct 154 from 190 and we're left 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 13:
360 divided by 77 is 4 with a remainder of 52.
Write down 4 as next digit of the result. 
Result so far: 4227.4675324
Deduct 308 from 360 and we're left 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.

Step 14:
77 can be fit into 520 6 times, resulting in a remainder of 58.
Use 6 as the next digit of our solution. 
Result so far: 4227.46753246
If we take 462 away from 520, we end up 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.

The final result is 4227.46753246 with a remainder of 5.8e-08.
