We look at the division of 16673410 by 836 
The aim is to understand the frequency of 836 in 16673410.

Step 1:
The number 836 fits into 1 0 times, leaving a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Include the next digit (6) from the dividend after 1, then repeat: 16 / 836

Let's proceed to step 2:
836 can be fit into 16 0 times, resulting in a remainder of 16.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 16 to get 16.
Fetch the next digit (6) from the dividend, attach it to 16 and continue: 166 / 836

Let's proceed to step 3:
If we divide 166 by 836, we get 0 and a remainder of 166.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 166 and we're left with 166.
Include the next digit (7) from the dividend after 166, then repeat: 1667 / 836

Going ahead to step 4:
836 goes into 1667 1 times with a remainder of 831.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 836 away from 1667, we end up with 831.
Append the next digit (3) from the dividend to 831 and continue with: 8313 / 836

Moving on to step 5:
The number 836 fits into 8313 9 times, leaving a remainder of 789.
The number 9 becomes the next digit in our result. 
Result so far: 19.0
Subtracting 7524 from 8313 leaves us with 789.
Append the next digit (4) from the dividend to 789 and continue with: 7894 / 836

On to step 6:
If we divide 7894 by 836, we get 9 and a remainder of 370.
The number 9 becomes the next digit in our result. 
Result so far: 199.0
If we subtract 7524 from 7894, we get 370.
Bring next digit (1) of the dividend behind the 370 and repeat the process: 3701 / 836

Going ahead to step 7:
The number 836 fits into 3701 4 times, leaving a remainder of 357.
The next digit of our result is 4. 
Result so far: 1994.0
The remainder is 357 after subtracting 3344 from 3701.
Bring next digit (0) of the dividend behind the 357 and repeat the process: 3570 / 836

Let's proceed to step 8:
If we divide 3570 by 836, we get 4 and a remainder of 226.
Put 4 as the next digit of the answer. 
Result so far: 19944.0
If we subtract 3344 from 3570, we get 226.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2260, and continue the process.

Moving on to step 9:
836 can be fit into 2260 2 times, resulting in a remainder of 588.
The number 2 becomes the next digit in our result. 
Result so far: 19944.2
If we subtract 1672 from 2260, we get 588.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5880, and continue the process.

Let's proceed to step 10:
When dividing 5880 by 836, we get 7 with a remainder of 28.
Record the quotient 7 as the next digit in the result. 
Result so far: 19944.27
The remainder is 28 after subtracting 5852 from 5880.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

On to step 11:
When dividing 280 by 836, we get 0 with a remainder of 280.
Use 0 as the next digit of our solution. 
Result so far: 19944.27
Subtracting 0 from 280 leaves us with 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Step 12:
When dividing 2800 by 836, we get 3 with a remainder of 292.
Write down 3 as next digit of the result. 
Result so far: 19944.2703
The remainder is 292 after subtracting 2508 from 2800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2920, and continue the process.

Moving on to step 13:
If we divide 2920 by 836, we get 3 and a remainder of 412.
Use 3 as the next digit of our solution. 
Result so far: 19944.27033
Deduct 2508 from 2920 and we're left with 412.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4120, and continue the process.

The quotient of the division is 19944.27033, and the remainder is 0.000412.
