13389659 ÷ 396 
The aim is to understand the frequency of 396 in 13389659.

Going ahead to step 1:
396 can be fit into 1 0 times, resulting in a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Bring next digit (3) of the dividend behind the 1 and repeat the process: 13 / 396

On to step 2:
The number 396 fits into 13 0 times, leaving a remainder of 13.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 13 and we're left with 13.
Bring next digit (3) of the dividend behind the 13 and repeat the process: 133 / 396

Step 3:
If we divide 133 by 396, we get 0 and a remainder of 133.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 133, we end up with 133.
Grab the next digit (8) from the dividend, add it to 133, then carry on: 1338 / 396

Step 4:
1338 divided by 396 is 3 with a remainder of 150.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtracting 1188 from 1338 leaves us with 150.
Bring next digit (9) of the dividend behind the 150 and repeat the process: 1509 / 396

Moving on to step 5:
1509 divided by 396 is 3 with a remainder of 321.
The next digit of our result is 3. 
Result so far: 33.0
If we take 1188 away from 1509, we end up with 321.
Grab the next digit (6) from the dividend, add it to 321, then carry on: 3216 / 396

Step 6:
The number 396 fits into 3216 8 times, leaving a remainder of 48.
The next digit of our result is 8. 
Result so far: 338.0
If we take 3168 away from 3216, we end up with 48.
Include the next digit (5) from the dividend after 48, then repeat: 485 / 396

Step 7:
396 can be fit into 485 1 times, resulting in a remainder of 89.
Use 1 as the next digit of our solution. 
Result so far: 3381.0
Deduct 396 from 485 and we're left with 89.
Grab the next digit (9) from the dividend, add it to 89, then carry on: 899 / 396

Advancing to step 8:
The number 396 fits into 899 2 times, leaving a remainder of 107.
Use 2 as the next digit of our solution. 
Result so far: 33812.0
Subtracting 792 from 899 leaves us with 107.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1070, and continue the process.

Moving on to step 9:
1070 divided by 396 is 2 with a remainder of 278.
Record the quotient 2 as the next digit in the result. 
Result so far: 33812.2
If we subtract 792 from 1070, we get 278.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2780, and continue the process.

Moving on to step 10:
2780 divided by 396 is 7 with a remainder of 8.
The next digit of our result is 7. 
Result so far: 33812.27
If we take 2772 away from 2780, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 11:
The number 396 fits into 80 0 times, leaving a remainder of 80.
Record the quotient 0 as the next digit in the result. 
Result so far: 33812.27
If we take 0 away from 80, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Advancing to step 12:
396 can be fit into 800 2 times, resulting in a remainder of 8.
The next digit of our result is 2. 
Result so far: 33812.2702
If we subtract 792 from 800, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 13:
The number 396 fits into 80 0 times, leaving a remainder of 80.
Put 0 as the next digit of the answer. 
Result so far: 33812.2702
The remainder is 80 after subtracting 0 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Moving on to step 14:
When dividing 800 by 396, we get 2 with a remainder of 8.
The next digit of our result is 2. 
Result so far: 33812.270202
The remainder is 8 after subtracting 792 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 15:
80 divided by 396 is 0 with a remainder of 80.
Write down 0 as next digit of the result. 
Result so far: 33812.270202
If we take 0 away from 80, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Moving on to step 16:
396 can be fit into 800 2 times, resulting in a remainder of 8.
Record the quotient 2 as the next digit in the result. 
Result so far: 33812.27020202
Subtracting 792 from 800 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Our division results in 33812.27020202 with a remaining 8e-09.
