103429 divided by 52 
The aim is to understand the frequency of 52 in 103429.

Going ahead to step 1:
When dividing 1 by 52, we get 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Bring next digit (0) of the dividend behind the 1 and repeat the process: 10 / 52

Moving on to step 2:
52 can be fit into 10 0 times, resulting in a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 10, we end up with 10.
Grab the next digit (3) from the dividend, add it to 10, then carry on: 103 / 52

Advancing to step 3:
103 divided by 52 is 1 with a remainder of 51.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 52 from 103 and we're left with 51.
Include the next digit (4) from the dividend after 51, then repeat: 514 / 52

Step 4:
The number 52 fits into 514 9 times, leaving a remainder of 46.
The next digit of our result is 9. 
Result so far: 19.0
If we subtract 468 from 514, we get 46.
Bring next digit (2) of the dividend behind the 46 and repeat the process: 462 / 52

Going ahead to step 5:
If we divide 462 by 52, we get 8 and a remainder of 46.
The next digit of our result is 8. 
Result so far: 198.0
If we take 416 away from 462, we end up with 46.
Fetch the next digit (9) from the dividend, attach it to 46 and continue: 469 / 52

Let's proceed to step 6:
469 divided by 52 is 9 with a remainder of 1.
The next digit of our result is 9. 
Result so far: 1989.0
If we take 468 away from 469, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 7:
When dividing 10 by 52, we get 0 with a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 1989.0
Subtract 0 from 10 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 8:
When dividing 100 by 52, we get 1 with a remainder of 48.
Write down 1 as next digit of the result. 
Result so far: 1989.01
If we subtract 52 from 100, we get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Moving on to step 9:
If we divide 480 by 52, we get 9 and a remainder of 12.
Put 9 as the next digit of the answer. 
Result so far: 1989.019
Deduct 468 from 480 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 10:
When dividing 120 by 52, we get 2 with a remainder of 16.
The number 2 becomes the next digit in our result. 
Result so far: 1989.0192
The remainder is 16 after subtracting 104 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 11:
The number 52 fits into 160 3 times, leaving a remainder of 4.
The number 3 becomes the next digit in our result. 
Result so far: 1989.01923
Deduct 156 from 160 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 12:
The number 52 fits into 40 0 times, leaving a remainder of 40.
The next digit of our result is 0. 
Result so far: 1989.01923
Deduct 0 from 40 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 13:
52 can be fit into 400 7 times, resulting in a remainder of 36.
Write down 7 as next digit of the result. 
Result so far: 1989.0192307
Deduct 364 from 400 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Moving on to step 14:
52 can be fit into 360 6 times, resulting in a remainder of 48.
Record the quotient 6 as the next digit in the result. 
Result so far: 1989.01923076
Deduct 312 from 360 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

The final outcome is 1989.01923076, with a leftover of 4.8e-08.
