We're dividing 53501389 by 775 
The aim is to understand the frequency of 775 in 53501389.

On to step 1:
The number 775 fits into 5 0 times, leaving a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Grab the next digit (3) from the dividend, add it to 5, then carry on: 53 / 775

Going ahead to step 2:
775 goes into 53 0 times with a remainder of 53.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 53 to get 53.
Fetch the next digit (5) from the dividend, attach it to 53 and continue: 535 / 775

Moving on to step 3:
775 goes into 535 0 times with a remainder of 535.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 535 leaves us with 535.
Append the next digit (0) from the dividend to 535 and continue with: 5350 / 775

Step 4:
When dividing 5350 by 775, we get 6 with a remainder of 700.
The next digit of our result is 6. 
Result so far: 6.0
Subtract 4650 from 5350 to get 700.
Include the next digit (1) from the dividend after 700, then repeat: 7001 / 775

Moving on to step 5:
When dividing 7001 by 775, we get 9 with a remainder of 26.
Write down 9 as next digit of the result. 
Result so far: 69.0
Subtract 6975 from 7001 to get 26.
Include the next digit (3) from the dividend after 26, then repeat: 263 / 775

Step 6:
775 can be fit into 263 0 times, resulting in a remainder of 263.
The next digit of our result is 0. 
Result so far: 690.0
If we subtract 0 from 263, we get 263.
Append the next digit (8) from the dividend to 263 and continue with: 2638 / 775

Moving on to step 7:
2638 divided by 775 is 3 with a remainder of 313.
Write down 3 as next digit of the result. 
Result so far: 6903.0
The remainder is 313 after subtracting 2325 from 2638.
Append the next digit (9) from the dividend to 313 and continue with: 3139 / 775

Going ahead to step 8:
The number 775 fits into 3139 4 times, leaving a remainder of 39.
Use 4 as the next digit of our solution. 
Result so far: 69034.0
Deduct 3100 from 3139 and we're left with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Moving on to step 9:
775 can be fit into 390 0 times, resulting in a remainder of 390.
Put 0 as the next digit of the answer. 
Result so far: 69034.0
Deduct 0 from 390 and we're left with 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3900, and continue the process.

Moving on to step 10:
When dividing 3900 by 775, we get 5 with a remainder of 25.
Record the quotient 5 as the next digit in the result. 
Result so far: 69034.05
If we take 3875 away from 3900, 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:
When dividing 250 by 775, we get 0 with a remainder of 250.
Put 0 as the next digit of the answer. 
Result so far: 69034.05
Subtracting 0 from 250 leaves us with 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Moving on to step 12:
775 can be fit into 2500 3 times, resulting in a remainder of 175.
The next digit of our result is 3. 
Result so far: 69034.0503
If we take 2325 away from 2500, we end up with 175.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

Going ahead to step 13:
1750 divided by 775 is 2 with a remainder of 200.
Write down 2 as next digit of the result. 
Result so far: 69034.05032
If we take 1550 away from 1750, we end up with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Moving on to step 14:
If we divide 2000 by 775, we get 2 and a remainder of 450.
Use 2 as the next digit of our solution. 
Result so far: 69034.050322
Deduct 1550 from 2000 and we're left with 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

After the division, we end up with 69034.050322 and a remainder of 4.5e-05.
