We look at the division of 53683215 by 775 
The aim is to understand the frequency of 775 in 53683215.

Let's proceed to step 1:
775 can be fit into 5 0 times, resulting in a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Take the next digit (3) from the dividend and append it to 5, then repeat: 53 / 775

On to step 2:
When dividing 53 by 775, we get 0 with a remainder of 53.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 53, we get 53.
Fetch the next digit (6) from the dividend, attach it to 53 and continue: 536 / 775

Step 3:
When dividing 536 by 775, we get 0 with a remainder of 536.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 536, we end up with 536.
Append the next digit (8) from the dividend to 536 and continue with: 5368 / 775

Let's proceed to step 4:
775 can be fit into 5368 6 times, resulting in a remainder of 718.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
The remainder is 718 after subtracting 4650 from 5368.
Include the next digit (3) from the dividend after 718, then repeat: 7183 / 775

On to step 5:
775 goes into 7183 9 times with a remainder of 208.
The next digit of our result is 9. 
Result so far: 69.0
If we take 6975 away from 7183, we end up with 208.
Bring next digit (2) of the dividend behind the 208 and repeat the process: 2082 / 775

Step 6:
2082 divided by 775 is 2 with a remainder of 532.
Write down 2 as next digit of the result. 
Result so far: 692.0
If we take 1550 away from 2082, we end up with 532.
Grab the next digit (1) from the dividend, add it to 532, then carry on: 5321 / 775

Going ahead to step 7:
775 can be fit into 5321 6 times, resulting in a remainder of 671.
The number 6 becomes the next digit in our result. 
Result so far: 6926.0
Deduct 4650 from 5321 and we're left with 671.
Fetch the next digit (5) from the dividend, attach it to 671 and continue: 6715 / 775

Going ahead to step 8:
775 can be fit into 6715 8 times, resulting in a remainder of 515.
Write down 8 as next digit of the result. 
Result so far: 69268.0
Subtracting 6200 from 6715 leaves us with 515.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5150, and continue the process.

On to step 9:
If we divide 5150 by 775, we get 6 and a remainder of 500.
The number 6 becomes the next digit in our result. 
Result so far: 69268.6
If we subtract 4650 from 5150, we get 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

Step 10:
The number 775 fits into 5000 6 times, leaving a remainder of 350.
The number 6 becomes the next digit in our result. 
Result so far: 69268.66
Subtracting 4650 from 5000 leaves us with 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

The final result is 69268.66 with a remainder of 0.35.
