Let's divide 12831806 by 406
The aim is to understand the frequency of 406 in 12831806.

Step 1:
406 goes into 1 0 times with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 406

On to step 2:
12 divided by 406 is 0 with a remainder of 12.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 12, we end up with 12.
Grab the next digit (8) from the dividend, add it to 12, then carry on: 128 / 406

Advancing to step 3:
406 can be fit into 128 0 times, resulting in a remainder of 128.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 128 to get 128.
Fetch the next digit (3) from the dividend, attach it to 128 and continue: 1283 / 406

Step 4:
The number 406 fits into 1283 3 times, leaving a remainder of 65.
Write down 3 as next digit of the result. 
Result so far: 3.0
Subtracting 1218 from 1283 leaves us with 65.
Bring next digit (1) of the dividend behind the 65 and repeat the process: 651 / 406

Let's proceed to step 5:
406 can be fit into 651 1 times, resulting in a remainder of 245.
Use 1 as the next digit of our solution. 
Result so far: 31.0
Subtract 406 from 651 to get 245.
Bring next digit (8) of the dividend behind the 245 and repeat the process: 2458 / 406

Going ahead to step 6:
If we divide 2458 by 406, we get 6 and a remainder of 22.
The number 6 becomes the next digit in our result. 
Result so far: 316.0
Deduct 2436 from 2458 and we're left with 22.
Fetch the next digit (0) from the dividend, attach it to 22 and continue: 220 / 406

Advancing to step 7:
When dividing 220 by 406, we get 0 with a remainder of 220.
The next digit of our result is 0. 
Result so far: 3160.0
Subtract 0 from 220 to get 220.
Fetch the next digit (6) from the dividend, attach it to 220 and continue: 2206 / 406

Let's proceed to step 8:
When dividing 2206 by 406, we get 5 with a remainder of 176.
Put 5 as the next digit of the answer. 
Result so far: 31605.0
If we take 2030 away from 2206, we end up with 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

Going ahead to step 9:
1760 divided by 406 is 4 with a remainder of 136.
The next digit of our result is 4. 
Result so far: 31605.4
Subtract 1624 from 1760 to get 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Let's proceed to step 10:
406 goes into 1360 3 times with a remainder of 142.
Record the quotient 3 as the next digit in the result. 
Result so far: 31605.43
If we take 1218 away from 1360, we end up with 142.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1420, and continue the process.

On to step 11:
1420 divided by 406 is 3 with a remainder of 202.
The next digit of our result is 3. 
Result so far: 31605.433
If we subtract 1218 from 1420, we get 202.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2020, and continue the process.

In conclusion, the division gives 31605.433 with a balance of 0.0202.
