Let's divide 16880707 by 838
The aim is to understand the frequency of 838 in 16880707.

On to step 1:
The number 838 fits into 1 0 times, leaving a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Take the next digit (6) from the dividend and append it to 1, then repeat: 16 / 838

Advancing to step 2:
838 can be fit into 16 0 times, resulting in a remainder of 16.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 16 leaves us with 16.
Grab the next digit (8) from the dividend, add it to 16, then carry on: 168 / 838

Step 3:
838 can be fit into 168 0 times, resulting in a remainder of 168.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 168 leaves us with 168.
Append the next digit (8) from the dividend to 168 and continue with: 1688 / 838

On to step 4:
If we divide 1688 by 838, we get 2 and a remainder of 12.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Deduct 1676 from 1688 and we're left with 12.
Append the next digit (0) from the dividend to 12 and continue with: 120 / 838

On to step 5:
838 goes into 120 0 times with a remainder of 120.
Use 0 as the next digit of our solution. 
Result so far: 20.0
If we subtract 0 from 120, we get 120.
Append the next digit (7) from the dividend to 120 and continue with: 1207 / 838

Going ahead to step 6:
If we divide 1207 by 838, we get 1 and a remainder of 369.
Use 1 as the next digit of our solution. 
Result so far: 201.0
If we take 838 away from 1207, we end up with 369.
Grab the next digit (0) from the dividend, add it to 369, then carry on: 3690 / 838

On to step 7:
3690 divided by 838 is 4 with a remainder of 338.
Use 4 as the next digit of our solution. 
Result so far: 2014.0
If we subtract 3352 from 3690, we get 338.
Append the next digit (7) from the dividend to 338 and continue with: 3387 / 838

Advancing to step 8:
The number 838 fits into 3387 4 times, leaving a remainder of 35.
Use 4 as the next digit of our solution. 
Result so far: 20144.0
If we subtract 3352 from 3387, we get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Advancing to step 9:
838 goes into 350 0 times with a remainder of 350.
The next digit of our result is 0. 
Result so far: 20144.0
Deduct 0 from 350 and we're left with 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

Let's proceed to step 10:
When dividing 3500 by 838, we get 4 with a remainder of 148.
The next digit of our result is 4. 
Result so far: 20144.04
If we take 3352 away from 3500, we end up with 148.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

On to step 11:
838 can be fit into 1480 1 times, resulting in a remainder of 642.
Put 1 as the next digit of the answer. 
Result so far: 20144.041
The remainder is 642 after subtracting 838 from 1480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6420, and continue the process.

Step 12:
The number 838 fits into 6420 7 times, leaving a remainder of 554.
The number 7 becomes the next digit in our result. 
Result so far: 20144.0417
If we subtract 5866 from 6420, we get 554.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5540, and continue the process.

Step 13:
If we divide 5540 by 838, we get 6 and a remainder of 512.
Use 6 as the next digit of our solution. 
Result so far: 20144.04176
Subtracting 5028 from 5540 leaves us with 512.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5120, and continue the process.

Going ahead to step 14:
5120 divided by 838 is 6 with a remainder of 92.
Put 6 as the next digit of the answer. 
Result so far: 20144.041766
Deduct 5028 from 5120 and we're left with 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Our division results in 20144.041766 with a remaining 9.2e-06.
