We're dividing 530253 by 77 
The aim is to understand the frequency of 77 in 530253.

Moving on to step 1:
5 divided by 77 is 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Append the next digit (3) from the dividend to 5 and continue with: 53 / 77

Moving on to step 2:
If we divide 53 by 77, we get 0 and a remainder of 53.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 53 leaves us with 53.
Include the next digit (0) from the dividend after 53, then repeat: 530 / 77

Going ahead to step 3:
The number 77 fits into 530 6 times, leaving a remainder of 68.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
Subtract 462 from 530 to get 68.
Grab the next digit (2) from the dividend, add it to 68, then carry on: 682 / 77

Step 4:
If we divide 682 by 77, we get 8 and a remainder of 66.
Use 8 as the next digit of our solution. 
Result so far: 68.0
Subtract 616 from 682 to get 66.
Fetch the next digit (5) from the dividend, attach it to 66 and continue: 665 / 77

Moving on to step 5:
665 divided by 77 is 8 with a remainder of 49.
Record the quotient 8 as the next digit in the result. 
Result so far: 688.0
Subtract 616 from 665 to get 49.
Include the next digit (3) from the dividend after 49, then repeat: 493 / 77

Going ahead to step 6:
493 divided by 77 is 6 with a remainder of 31.
Use 6 as the next digit of our solution. 
Result so far: 6886.0
If we subtract 462 from 493, we get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Moving on to step 7:
The number 77 fits into 310 4 times, leaving a remainder of 2.
Record the quotient 4 as the next digit in the result. 
Result so far: 6886.4
Deduct 308 from 310 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 8:
20 divided by 77 is 0 with a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 6886.4
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 9:
77 can be fit into 200 2 times, resulting in a remainder of 46.
Record the quotient 2 as the next digit in the result. 
Result so far: 6886.402
Subtract 154 from 200 to get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

On to step 10:
If we divide 460 by 77, we get 5 and a remainder of 75.
Write down 5 as next digit of the result. 
Result so far: 6886.4025
The remainder is 75 after subtracting 385 from 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Let's proceed to step 11:
The number 77 fits into 750 9 times, leaving a remainder of 57.
Use 9 as the next digit of our solution. 
Result so far: 6886.40259
Deduct 693 from 750 and we're left with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

On to step 12:
If we divide 570 by 77, we get 7 and a remainder of 31.
Write down 7 as next digit of the result. 
Result so far: 6886.402597
Deduct 539 from 570 and we're left with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

On to step 13:
77 can be fit into 310 4 times, resulting in a remainder of 2.
Put 4 as the next digit of the answer. 
Result so far: 6886.4025974
If we subtract 308 from 310, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 14:
77 can be fit into 20 0 times, resulting in a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 6886.4025974
If we take 0 away from 20, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The final outcome is 6886.4025974, with a leftover of 2e-08.
