We look at the division of 77403555 by 52 
The aim is to understand the frequency of 52 in 77403555.

Moving on to step 1:
The number 52 fits into 7 0 times, leaving a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Append the next digit (7) from the dividend to 7 and continue with: 77 / 52

On to step 2:
52 goes into 77 1 times with a remainder of 25.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 25 after subtracting 52 from 77.
Include the next digit (4) from the dividend after 25, then repeat: 254 / 52

Step 3:
52 can be fit into 254 4 times, resulting in a remainder of 46.
The next digit of our result is 4. 
Result so far: 14.0
Subtracting 208 from 254 leaves us with 46.
Include the next digit (0) from the dividend after 46, then repeat: 460 / 52

Advancing to step 4:
When dividing 460 by 52, we get 8 with a remainder of 44.
Record the quotient 8 as the next digit in the result. 
Result so far: 148.0
If we take 416 away from 460, we end up with 44.
Include the next digit (3) from the dividend after 44, then repeat: 443 / 52

Let's proceed to step 5:
52 goes into 443 8 times with a remainder of 27.
Write down 8 as next digit of the result. 
Result so far: 1488.0
If we subtract 416 from 443, we get 27.
Append the next digit (5) from the dividend to 27 and continue with: 275 / 52

Going ahead to step 6:
If we divide 275 by 52, we get 5 and a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 14885.0
Subtract 260 from 275 to get 15.
Append the next digit (5) from the dividend to 15 and continue with: 155 / 52

Step 7:
52 can be fit into 155 2 times, resulting in a remainder of 51.
Record the quotient 2 as the next digit in the result. 
Result so far: 148852.0
Subtract 104 from 155 to get 51.
Fetch the next digit (5) from the dividend, attach it to 51 and continue: 515 / 52

Let's proceed to step 8:
If we divide 515 by 52, we get 9 and a remainder of 47.
Put 9 as the next digit of the answer. 
Result so far: 1488529.0
If we subtract 468 from 515, we get 47.
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 9:
52 can be fit into 470 9 times, resulting in a remainder of 2.
Use 9 as the next digit of our solution. 
Result so far: 1488529.9
Deduct 468 from 470 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 10:
When dividing 20 by 52, we get 0 with a remainder of 20.
The next digit of our result is 0. 
Result so far: 1488529.9
Subtract 0 from 20 to get 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 11:
200 divided by 52 is 3 with a remainder of 44.
Put 3 as the next digit of the answer. 
Result so far: 1488529.903
If we subtract 156 from 200, we get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Let's proceed to step 12:
440 divided by 52 is 8 with a remainder of 24.
Write down 8 as next digit of the result. 
Result so far: 1488529.9038
If we take 416 away from 440, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 13:
When dividing 240 by 52, we get 4 with a remainder of 32.
Use 4 as the next digit of our solution. 
Result so far: 1488529.90384
The remainder is 32 after subtracting 208 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 14:
The number 52 fits into 320 6 times, leaving a remainder of 8.
Put 6 as the next digit of the answer. 
Result so far: 1488529.903846
Subtract 312 from 320 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.

On to step 15:
The number 52 fits into 80 1 times, leaving a remainder of 28.
Write down 1 as next digit of the result. 
Result so far: 1488529.9038461
If we take 52 away from 80, we end up with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

On to step 16:
The number 52 fits into 280 5 times, leaving a remainder of 20.
Use 5 as the next digit of our solution. 
Result so far: 1488529.90384615
Subtracting 260 from 280 leaves us 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 result is 1488529.90384615 with a remainder of 2e-08.
