Let's divide 29018208 by 686
The aim is to understand the frequency of 686 in 29018208.

Step 1:
The number 686 fits into 2 0 times, leaving a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Bring next digit (9) of the dividend behind the 2 and repeat the process: 29 / 686

On to step 2:
29 divided by 686 is 0 with a remainder of 29.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 29, we get 29.
Fetch the next digit (0) from the dividend, attach it to 29 and continue: 290 / 686

Advancing to step 3:
290 divided by 686 is 0 with a remainder of 290.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 290 to get 290.
Append the next digit (1) from the dividend to 290 and continue with: 2901 / 686

Step 4:
When dividing 2901 by 686, we get 4 with a remainder of 157.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Deduct 2744 from 2901 and we're left with 157.
Include the next digit (8) from the dividend after 157, then repeat: 1578 / 686

Advancing to step 5:
The number 686 fits into 1578 2 times, leaving a remainder of 206.
The next digit of our result is 2. 
Result so far: 42.0
Subtracting 1372 from 1578 leaves us with 206.
Include the next digit (2) from the dividend after 206, then repeat: 2062 / 686

Going ahead to step 6:
686 goes into 2062 3 times with a remainder of 4.
Use 3 as the next digit of our solution. 
Result so far: 423.0
Subtracting 2058 from 2062 leaves us with 4.
Bring next digit (0) of the dividend behind the 4 and repeat the process: 40 / 686

Let's proceed to step 7:
686 goes into 40 0 times with a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 4230.0
If we take 0 away from 40, we end up with 40.
Include the next digit (8) from the dividend after 40, then repeat: 408 / 686

Moving on to step 8:
686 can be fit into 408 0 times, resulting in a remainder of 408.
The number 0 becomes the next digit in our result. 
Result so far: 42300.0
Subtract 0 from 408 to get 408.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4080, and continue the process.

Going ahead to step 9:
4080 divided by 686 is 5 with a remainder of 650.
The number 5 becomes the next digit in our result. 
Result so far: 42300.5
Deduct 3430 from 4080 and we're left with 650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6500, and continue the process.

Advancing to step 10:
686 can be fit into 6500 9 times, resulting in a remainder of 326.
Put 9 as the next digit of the answer. 
Result so far: 42300.59
If we subtract 6174 from 6500, we get 326.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3260, and continue the process.

On to step 11:
When dividing 3260 by 686, we get 4 with a remainder of 516.
Put 4 as the next digit of the answer. 
Result so far: 42300.594
Deduct 2744 from 3260 and we're left with 516.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5160, and continue the process.

On to step 12:
686 goes into 5160 7 times with a remainder of 358.
Record the quotient 7 as the next digit in the result. 
Result so far: 42300.5947
Deduct 4802 from 5160 and we're left with 358.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3580, and continue the process.

Let's proceed to step 13:
If we divide 3580 by 686, we get 5 and a remainder of 150.
Write down 5 as next digit of the result. 
Result so far: 42300.59475
If we take 3430 away from 3580, we end up with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Advancing to step 14:
686 goes into 1500 2 times with a remainder of 128.
Write down 2 as next digit of the result. 
Result so far: 42300.594752
The remainder is 128 after subtracting 1372 from 1500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Step 15:
686 can be fit into 1280 1 times, resulting in a remainder of 594.
Use 1 as the next digit of our solution. 
Result so far: 42300.5947521
If we subtract 686 from 1280, we get 594.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5940, and continue the process.

Step 16:
686 can be fit into 5940 8 times, resulting in a remainder of 452.
Record the quotient 8 as the next digit in the result. 
Result so far: 42300.59475218
The remainder is 452 after subtracting 5488 from 5940.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4520, and continue the process.

After the division, we end up with 42300.59475218 and a remainder of 4.52e-07.
