We look at the division of 16786665 by 806 
The aim is to understand the frequency of 806 in 16786665.

Let's proceed to step 1:
The number 806 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.
Bring next digit (6) of the dividend behind the 1 and repeat the process: 16 / 806

Let's proceed to step 2:
The number 806 fits into 16 0 times, leaving a remainder of 16.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 16, we end up with 16.
Grab the next digit (7) from the dividend, add it to 16, then carry on: 167 / 806

Going ahead to step 3:
167 divided by 806 is 0 with a remainder of 167.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 167 and we're left with 167.
Append the next digit (8) from the dividend to 167 and continue with: 1678 / 806

Moving on to step 4:
If we divide 1678 by 806, we get 2 and a remainder of 66.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we subtract 1612 from 1678, we get 66.
Grab the next digit (6) from the dividend, add it to 66, then carry on: 666 / 806

Step 5:
When dividing 666 by 806, we get 0 with a remainder of 666.
Record the quotient 0 as the next digit in the result. 
Result so far: 20.0
If we take 0 away from 666, we end up with 666.
Bring next digit (6) of the dividend behind the 666 and repeat the process: 6666 / 806

Advancing to step 6:
806 can be fit into 6666 8 times, resulting in a remainder of 218.
Put 8 as the next digit of the answer. 
Result so far: 208.0
Subtracting 6448 from 6666 leaves us with 218.
Bring next digit (6) of the dividend behind the 218 and repeat the process: 2186 / 806

Moving on to step 7:
806 can be fit into 2186 2 times, resulting in a remainder of 574.
Record the quotient 2 as the next digit in the result. 
Result so far: 2082.0
If we take 1612 away from 2186, we end up with 574.
Take the next digit (5) from the dividend and append it to 574, then repeat: 5745 / 806

Moving on to step 8:
806 goes into 5745 7 times with a remainder of 103.
The next digit of our result is 7. 
Result so far: 20827.0
Subtracting 5642 from 5745 leaves us with 103.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1030, and continue the process.

On to step 9:
1030 divided by 806 is 1 with a remainder of 224.
The next digit of our result is 1. 
Result so far: 20827.1
Subtract 806 from 1030 to get 224.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

Step 10:
2240 divided by 806 is 2 with a remainder of 628.
The number 2 becomes the next digit in our result. 
Result so far: 20827.12
Subtract 1612 from 2240 to get 628.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6280, and continue the process.

Going ahead to step 11:
If we divide 6280 by 806, we get 7 and a remainder of 638.
The number 7 becomes the next digit in our result. 
Result so far: 20827.127
Subtracting 5642 from 6280 leaves us with 638.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6380, and continue the process.

On to step 12:
When dividing 6380 by 806, we get 7 with a remainder of 738.
Use 7 as the next digit of our solution. 
Result so far: 20827.1277
Subtracting 5642 from 6380 leaves us with 738.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7380, and continue the process.

In conclusion, the division gives 20827.1277 with a balance of 0.00738.
