51253411 divided by 392 
The aim is to understand the frequency of 392 in 51253411.

Let's proceed to step 1:
5 divided by 392 is 0 with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Bring next digit (1) of the dividend behind the 5 and repeat the process: 51 / 392

Moving on to step 2:
If we divide 51 by 392, we get 0 and a remainder of 51.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 51 after subtracting 0 from 51.
Include the next digit (2) from the dividend after 51, then repeat: 512 / 392

Let's proceed to step 3:
392 goes into 512 1 times with a remainder of 120.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 392 from 512 and we're left with 120.
Append the next digit (5) from the dividend to 120 and continue with: 1205 / 392

On to step 4:
The number 392 fits into 1205 3 times, leaving a remainder of 29.
Use 3 as the next digit of our solution. 
Result so far: 13.0
Subtract 1176 from 1205 to get 29.
Bring next digit (3) of the dividend behind the 29 and repeat the process: 293 / 392

Going ahead to step 5:
392 goes into 293 0 times with a remainder of 293.
Write down 0 as next digit of the result. 
Result so far: 130.0
Subtracting 0 from 293 leaves us with 293.
Include the next digit (4) from the dividend after 293, then repeat: 2934 / 392

Let's proceed to step 6:
If we divide 2934 by 392, we get 7 and a remainder of 190.
Write down 7 as next digit of the result. 
Result so far: 1307.0
Subtracting 2744 from 2934 leaves us with 190.
Grab the next digit (1) from the dividend, add it to 190, then carry on: 1901 / 392

Going ahead to step 7:
If we divide 1901 by 392, we get 4 and a remainder of 333.
The next digit of our result is 4. 
Result so far: 13074.0
If we subtract 1568 from 1901, we get 333.
Fetch the next digit (1) from the dividend, attach it to 333 and continue: 3331 / 392

Going ahead to step 8:
The number 392 fits into 3331 8 times, leaving a remainder of 195.
Put 8 as the next digit of the answer. 
Result so far: 130748.0
If we subtract 3136 from 3331, we get 195.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1950, and continue the process.

Let's proceed to step 9:
When dividing 1950 by 392, we get 4 with a remainder of 382.
Record the quotient 4 as the next digit in the result. 
Result so far: 130748.4
Subtract 1568 from 1950 to get 382.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3820, and continue the process.

Step 10:
If we divide 3820 by 392, we get 9 and a remainder of 292.
Write down 9 as next digit of the result. 
Result so far: 130748.49
If we take 3528 away from 3820, we end up with 292.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2920, and continue the process.

Advancing to step 11:
392 can be fit into 2920 7 times, resulting in a remainder of 176.
Put 7 as the next digit of the answer. 
Result so far: 130748.497
Deduct 2744 from 2920 and we're left with 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

Going ahead to step 12:
The number 392 fits into 1760 4 times, leaving a remainder of 192.
The next digit of our result is 4. 
Result so far: 130748.4974
If we take 1568 away from 1760, we end up with 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

Going ahead to step 13:
392 goes into 1920 4 times with a remainder of 352.
The next digit of our result is 4. 
Result so far: 130748.49744
The remainder is 352 after subtracting 1568 from 1920.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

After the division, we end up with 130748.49744 and a remainder of 0.000352.
