We look at the division of 16811694 by 339 
The aim is to understand the frequency of 339 in 16811694.

Advancing to step 1:
339 goes into 1 0 times with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Grab the next digit (6) from the dividend, add it to 1, then carry on: 16 / 339

Going ahead to step 2:
339 goes into 16 0 times with a remainder of 16.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 16, we end up with 16.
Include the next digit (8) from the dividend after 16, then repeat: 168 / 339

Moving on to step 3:
339 can be fit into 168 0 times, resulting in a remainder of 168.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 168 to get 168.
Include the next digit (1) from the dividend after 168, then repeat: 1681 / 339

On to step 4:
1681 divided by 339 is 4 with a remainder of 325.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Deduct 1356 from 1681 and we're left with 325.
Take the next digit (1) from the dividend and append it to 325, then repeat: 3251 / 339

On to step 5:
The number 339 fits into 3251 9 times, leaving a remainder of 200.
The next digit of our result is 9. 
Result so far: 49.0
The remainder is 200 after subtracting 3051 from 3251.
Grab the next digit (6) from the dividend, add it to 200, then carry on: 2006 / 339

Going ahead to step 6:
339 goes into 2006 5 times with a remainder of 311.
Record the quotient 5 as the next digit in the result. 
Result so far: 495.0
The remainder is 311 after subtracting 1695 from 2006.
Include the next digit (9) from the dividend after 311, then repeat: 3119 / 339

Moving on to step 7:
339 goes into 3119 9 times with a remainder of 68.
Record the quotient 9 as the next digit in the result. 
Result so far: 4959.0
Subtract 3051 from 3119 to get 68.
Append the next digit (4) from the dividend to 68 and continue with: 684 / 339

Advancing to step 8:
When dividing 684 by 339, we get 2 with a remainder of 6.
The next digit of our result is 2. 
Result so far: 49592.0
If we take 678 away from 684, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 9:
If we divide 60 by 339, we get 0 and a remainder of 60.
Record the quotient 0 as the next digit in the result. 
Result so far: 49592.0
Subtracting 0 from 60 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

On to step 10:
The number 339 fits into 600 1 times, leaving a remainder of 261.
Use 1 as the next digit of our solution. 
Result so far: 49592.01
The remainder is 261 after subtracting 339 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2610, and continue the process.

Let's proceed to step 11:
2610 divided by 339 is 7 with a remainder of 237.
Put 7 as the next digit of the answer. 
Result so far: 49592.017
Deduct 2373 from 2610 and we're left with 237.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2370, and continue the process.

Going ahead to step 12:
339 can be fit into 2370 6 times, resulting in a remainder of 336.
Write down 6 as next digit of the result. 
Result so far: 49592.0176
If we subtract 2034 from 2370, we get 336.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

Moving on to step 13:
339 goes into 3360 9 times with a remainder of 309.
Record the quotient 9 as the next digit in the result. 
Result so far: 49592.01769
If we subtract 3051 from 3360, we get 309.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3090, and continue the process.

Moving on to step 14:
339 goes into 3090 9 times with a remainder of 39.
The next digit of our result is 9. 
Result so far: 49592.017699
The remainder is 39 after subtracting 3051 from 3090.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Our division results in 49592.017699 with a remaining 3.9e-06.
