53002115 divided by 392 
The aim is to understand the frequency of 392 in 53002115.

Let's proceed to step 1:
When dividing 5 by 392, we get 0 with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Bring next digit (3) of the dividend behind the 5 and repeat the process: 53 / 392

Advancing to step 2:
When dividing 53 by 392, we get 0 with a remainder of 53.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 53 and we're left with 53.
Fetch the next digit (0) from the dividend, attach it to 53 and continue: 530 / 392

Going ahead to step 3:
The number 392 fits into 530 1 times, leaving a remainder of 138.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 392 away from 530, we end up with 138.
Append the next digit (0) from the dividend to 138 and continue with: 1380 / 392

Advancing to step 4:
392 goes into 1380 3 times with a remainder of 204.
Write down 3 as next digit of the result. 
Result so far: 13.0
Subtract 1176 from 1380 to get 204.
Bring next digit (2) of the dividend behind the 204 and repeat the process: 2042 / 392

Step 5:
2042 divided by 392 is 5 with a remainder of 82.
The next digit of our result is 5. 
Result so far: 135.0
If we take 1960 away from 2042, we end up with 82.
Fetch the next digit (1) from the dividend, attach it to 82 and continue: 821 / 392

Step 6:
If we divide 821 by 392, we get 2 and a remainder of 37.
Put 2 as the next digit of the answer. 
Result so far: 1352.0
If we take 784 away from 821, we end up with 37.
Include the next digit (1) from the dividend after 37, then repeat: 371 / 392

Moving on to step 7:
371 divided by 392 is 0 with a remainder of 371.
Record the quotient 0 as the next digit in the result. 
Result so far: 13520.0
Subtracting 0 from 371 leaves us with 371.
Take the next digit (5) from the dividend and append it to 371, then repeat: 3715 / 392

Advancing to step 8:
If we divide 3715 by 392, we get 9 and a remainder of 187.
Use 9 as the next digit of our solution. 
Result so far: 135209.0
Subtracting 3528 from 3715 leaves us with 187.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1870, and continue the process.

On to step 9:
392 can be fit into 1870 4 times, resulting in a remainder of 302.
The number 4 becomes the next digit in our result. 
Result so far: 135209.4
The remainder is 302 after subtracting 1568 from 1870.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3020, and continue the process.

Moving on to step 10:
392 can be fit into 3020 7 times, resulting in a remainder of 276.
Use 7 as the next digit of our solution. 
Result so far: 135209.47
If we subtract 2744 from 3020, we get 276.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2760, and continue the process.

Let's proceed to step 11:
392 goes into 2760 7 times with a remainder of 16.
The next digit of our result is 7. 
Result so far: 135209.477
Deduct 2744 from 2760 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The quotient of the division is 135209.477, and the remainder is 0.0016.
