We're dividing 945345 by 52 
The aim is to understand the frequency of 52 in 945345.

On to step 1:
52 goes into 9 0 times with a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Bring next digit (4) of the dividend behind the 9 and repeat the process: 94 / 52

Let's proceed to step 2:
When dividing 94 by 52, we get 1 with a remainder of 42.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 52 from 94 and we're left with 42.
Grab the next digit (5) from the dividend, add it to 42, then carry on: 425 / 52

Going ahead to step 3:
The number 52 fits into 425 8 times, leaving a remainder of 9.
The next digit of our result is 8. 
Result so far: 18.0
If we take 416 away from 425, we end up with 9.
Include the next digit (3) from the dividend after 9, then repeat: 93 / 52

Let's proceed to step 4:
52 goes into 93 1 times with a remainder of 41.
Put 1 as the next digit of the answer. 
Result so far: 181.0
Deduct 52 from 93 and we're left with 41.
Include the next digit (4) from the dividend after 41, then repeat: 414 / 52

Advancing to step 5:
When dividing 414 by 52, we get 7 with a remainder of 50.
Record the quotient 7 as the next digit in the result. 
Result so far: 1817.0
The remainder is 50 after subtracting 364 from 414.
Include the next digit (5) from the dividend after 50, then repeat: 505 / 52

Moving on to step 6:
The number 52 fits into 505 9 times, leaving a remainder of 37.
The next digit of our result is 9. 
Result so far: 18179.0
If we take 468 away from 505, we end up with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

On to step 7:
When dividing 370 by 52, we get 7 with a remainder of 6.
Use 7 as the next digit of our solution. 
Result so far: 18179.7
Subtracting 364 from 370 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 8:
60 divided by 52 is 1 with a remainder of 8.
Put 1 as the next digit of the answer. 
Result so far: 18179.71
If we subtract 52 from 60, we 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.

Let's proceed to step 9:
52 can be fit into 80 1 times, resulting in a remainder of 28.
The next digit of our result is 1. 
Result so far: 18179.711
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.

The quotient of the division is 18179.711, and the remainder is 0.0028.
