91547430 divided by 52 
The aim is to understand the frequency of 52 in 91547430.

Step 1:
52 can be fit into 9 0 times, resulting in a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Take the next digit (1) from the dividend and append it to 9, then repeat: 91 / 52

Going ahead to step 2:
52 goes into 91 1 times with a remainder of 39.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 52 from 91 and we're left with 39.
Grab the next digit (5) from the dividend, add it to 39, then carry on: 395 / 52

Advancing to step 3:
52 goes into 395 7 times with a remainder of 31.
The number 7 becomes the next digit in our result. 
Result so far: 17.0
Subtracting 364 from 395 leaves us with 31.
Fetch the next digit (4) from the dividend, attach it to 31 and continue: 314 / 52

Moving on to step 4:
The number 52 fits into 314 6 times, leaving a remainder of 2.
Write down 6 as next digit of the result. 
Result so far: 176.0
Subtracting 312 from 314 leaves us with 2.
Bring next digit (7) of the dividend behind the 2 and repeat the process: 27 / 52

Let's proceed to step 5:
The number 52 fits into 27 0 times, leaving a remainder of 27.
The number 0 becomes the next digit in our result. 
Result so far: 1760.0
If we take 0 away from 27, we end up with 27.
Include the next digit (4) from the dividend after 27, then repeat: 274 / 52

Moving on to step 6:
52 goes into 274 5 times with a remainder of 14.
Write down 5 as next digit of the result. 
Result so far: 17605.0
If we subtract 260 from 274, we get 14.
Bring next digit (3) of the dividend behind the 14 and repeat the process: 143 / 52

Advancing to step 7:
If we divide 143 by 52, we get 2 and a remainder of 39.
Record the quotient 2 as the next digit in the result. 
Result so far: 176052.0
If we subtract 104 from 143, we get 39.
Include the next digit (0) from the dividend after 39, then repeat: 390 / 52

Let's proceed to step 8:
52 can be fit into 390 7 times, resulting in a remainder of 26.
Write down 7 as next digit of the result. 
Result so far: 1760527.0
Subtracting 364 from 390 leaves us with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Moving on to step 9:
If we divide 260 by 52, we get 5 and a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 1760527.5
Deduct 260 from 260 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 10:
If we divide 0 by 52, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 1760527.5
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 11:
If we divide 0 by 52, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 1760527.5
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 1760527.5 and a remainder of 0.0.
