10203229 divided by 686 
The aim is to understand the frequency of 686 in 10203229.

Advancing to step 1:
686 goes into 1 0 times with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Grab the next digit (0) from the dividend, add it to 1, then carry on: 10 / 686

Advancing to step 2:
If we divide 10 by 686, we get 0 and a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 10, we get 10.
Take the next digit (2) from the dividend and append it to 10, then repeat: 102 / 686

Let's proceed to step 3:
686 goes into 102 0 times with a remainder of 102.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 102 after subtracting 0 from 102.
Take the next digit (0) from the dividend and append it to 102, then repeat: 1020 / 686

Let's proceed to step 4:
686 can be fit into 1020 1 times, resulting in a remainder of 334.
The next digit of our result is 1. 
Result so far: 1.0
If we take 686 away from 1020, we end up with 334.
Fetch the next digit (3) from the dividend, attach it to 334 and continue: 3343 / 686

Advancing to step 5:
3343 divided by 686 is 4 with a remainder of 599.
The number 4 becomes the next digit in our result. 
Result so far: 14.0
If we subtract 2744 from 3343, we get 599.
Append the next digit (2) from the dividend to 599 and continue with: 5992 / 686

Step 6:
686 can be fit into 5992 8 times, resulting in a remainder of 504.
Record the quotient 8 as the next digit in the result. 
Result so far: 148.0
If we subtract 5488 from 5992, we get 504.
Include the next digit (2) from the dividend after 504, then repeat: 5042 / 686

On to step 7:
When dividing 5042 by 686, we get 7 with a remainder of 240.
Use 7 as the next digit of our solution. 
Result so far: 1487.0
Subtract 4802 from 5042 to get 240.
Grab the next digit (9) from the dividend, add it to 240, then carry on: 2409 / 686

Going ahead to step 8:
686 goes into 2409 3 times with a remainder of 351.
Use 3 as the next digit of our solution. 
Result so far: 14873.0
The remainder is 351 after subtracting 2058 from 2409.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3510, and continue the process.

Moving on to step 9:
If we divide 3510 by 686, we get 5 and a remainder of 80.
Write down 5 as next digit of the result. 
Result so far: 14873.5
If we subtract 3430 from 3510, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Going ahead to step 10:
When dividing 800 by 686, we get 1 with a remainder of 114.
The next digit of our result is 1. 
Result so far: 14873.51
The remainder is 114 after subtracting 686 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

Advancing to step 11:
The number 686 fits into 1140 1 times, leaving a remainder of 454.
Put 1 as the next digit of the answer. 
Result so far: 14873.511
Subtracting 686 from 1140 leaves us with 454.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4540, and continue the process.

Our division results in 14873.511 with a remaining 0.0454.
