We look at the division of 13835389 by 792 
The aim is to understand the frequency of 792 in 13835389.

Advancing to step 1:
1 divided by 792 is 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Take the next digit (3) from the dividend and append it to 1, then repeat: 13 / 792

Going ahead to step 2:
The number 792 fits into 13 0 times, leaving a remainder of 13.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 13 after subtracting 0 from 13.
Grab the next digit (8) from the dividend, add it to 13, then carry on: 138 / 792

Going ahead to step 3:
When dividing 138 by 792, we get 0 with a remainder of 138.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 138, we end up with 138.
Take the next digit (3) from the dividend and append it to 138, then repeat: 1383 / 792

Going ahead to step 4:
1383 divided by 792 is 1 with a remainder of 591.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 591 after subtracting 792 from 1383.
Take the next digit (5) from the dividend and append it to 591, then repeat: 5915 / 792

On to step 5:
When dividing 5915 by 792, we get 7 with a remainder of 371.
Record the quotient 7 as the next digit in the result. 
Result so far: 17.0
Subtracting 5544 from 5915 leaves us with 371.
Bring next digit (3) of the dividend behind the 371 and repeat the process: 3713 / 792

Advancing to step 6:
If we divide 3713 by 792, we get 4 and a remainder of 545.
Use 4 as the next digit of our solution. 
Result so far: 174.0
The remainder is 545 after subtracting 3168 from 3713.
Take the next digit (8) from the dividend and append it to 545, then repeat: 5458 / 792

On to step 7:
5458 divided by 792 is 6 with a remainder of 706.
Write down 6 as next digit of the result. 
Result so far: 1746.0
Deduct 4752 from 5458 and we're left with 706.
Grab the next digit (9) from the dividend, add it to 706, then carry on: 7069 / 792

Let's proceed to step 8:
792 goes into 7069 8 times with a remainder of 733.
Put 8 as the next digit of the answer. 
Result so far: 17468.0
The remainder is 733 after subtracting 6336 from 7069.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7330, and continue the process.

Advancing to step 9:
792 goes into 7330 9 times with a remainder of 202.
Use 9 as the next digit of our solution. 
Result so far: 17468.9
If we subtract 7128 from 7330, we get 202.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2020, and continue the process.

Step 10:
When dividing 2020 by 792, we get 2 with a remainder of 436.
Put 2 as the next digit of the answer. 
Result so far: 17468.92
If we take 1584 away from 2020, we end up with 436.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4360, and continue the process.

Let's proceed to step 11:
4360 divided by 792 is 5 with a remainder of 400.
The next digit of our result is 5. 
Result so far: 17468.925
If we subtract 3960 from 4360, we get 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Moving on to step 12:
4000 divided by 792 is 5 with a remainder of 40.
The next digit of our result is 5. 
Result so far: 17468.9255
Deduct 3960 from 4000 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.

The quotient of the division is 17468.9255, and the remainder is 0.0004.
