We look at the division of 6428794 by 392 
The aim is to understand the frequency of 392 in 6428794.

Advancing to step 1:
When dividing 6 by 392, we get 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Take the next digit (4) from the dividend and append it to 6, then repeat: 64 / 392

Moving on to step 2:
392 can be fit into 64 0 times, resulting in a remainder of 64.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 64 leaves us with 64.
Take the next digit (2) from the dividend and append it to 64, then repeat: 642 / 392

Advancing to step 3:
When dividing 642 by 392, we get 1 with a remainder of 250.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 392 from 642 to get 250.
Take the next digit (8) from the dividend and append it to 250, then repeat: 2508 / 392

On to step 4:
392 goes into 2508 6 times with a remainder of 156.
Use 6 as the next digit of our solution. 
Result so far: 16.0
If we subtract 2352 from 2508, we get 156.
Bring next digit (7) of the dividend behind the 156 and repeat the process: 1567 / 392

Moving on to step 5:
392 can be fit into 1567 3 times, resulting in a remainder of 391.
The next digit of our result is 3. 
Result so far: 163.0
If we subtract 1176 from 1567, we get 391.
Fetch the next digit (9) from the dividend, attach it to 391 and continue: 3919 / 392

Going ahead to step 6:
3919 divided by 392 is 9 with a remainder of 391.
Use 9 as the next digit of our solution. 
Result so far: 1639.0
Deduct 3528 from 3919 and we're left with 391.
Append the next digit (4) from the dividend to 391 and continue with: 3914 / 392

Moving on to step 7:
392 goes into 3914 9 times with a remainder of 386.
The next digit of our result is 9. 
Result so far: 16399.0
Deduct 3528 from 3914 and we're left with 386.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3860, and continue the process.

Let's proceed to step 8:
3860 divided by 392 is 9 with a remainder of 332.
Record the quotient 9 as the next digit in the result. 
Result so far: 16399.9
Subtracting 3528 from 3860 leaves us with 332.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3320, and continue the process.

Going ahead to step 9:
When dividing 3320 by 392, we get 8 with a remainder of 184.
Write down 8 as next digit of the result. 
Result so far: 16399.98
If we take 3136 away from 3320, we end up with 184.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

Advancing to step 10:
If we divide 1840 by 392, we get 4 and a remainder of 272.
The next digit of our result is 4. 
Result so far: 16399.984
Subtracting 1568 from 1840 leaves us with 272.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2720, and continue the process.

Let's proceed to step 11:
If we divide 2720 by 392, we get 6 and a remainder of 368.
Use 6 as the next digit of our solution. 
Result so far: 16399.9846
Deduct 2352 from 2720 and we're left with 368.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

Going ahead to step 12:
392 goes into 3680 9 times with a remainder of 152.
Put 9 as the next digit of the answer. 
Result so far: 16399.98469
Deduct 3528 from 3680 and we're left with 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

Let's proceed to step 13:
The number 392 fits into 1520 3 times, leaving a remainder of 344.
Put 3 as the next digit of the answer. 
Result so far: 16399.984693
The remainder is 344 after subtracting 1176 from 1520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3440, and continue the process.

Let's proceed to step 14:
392 goes into 3440 8 times with a remainder of 304.
The next digit of our result is 8. 
Result so far: 16399.9846938
Subtract 3136 from 3440 to get 304.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

Moving on to step 15:
392 can be fit into 3040 7 times, resulting in a remainder of 296.
Use 7 as the next digit of our solution. 
Result so far: 16399.98469387
Subtracting 2744 from 3040 leaves us with 296.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2960, and continue the process.

The final result is 16399.98469387 with a remainder of 2.96e-07.
