17719747 divided by 853 
The aim is to understand the frequency of 853 in 17719747.

Step 1:
If we divide 1 by 853, we get 0 and a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Fetch the next digit (7) from the dividend, attach it to 1 and continue: 17 / 853

Advancing to step 2:
The number 853 fits into 17 0 times, leaving a remainder of 17.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 17, we get 17.
Grab the next digit (7) from the dividend, add it to 17, then carry on: 177 / 853

Moving on to step 3:
When dividing 177 by 853, we get 0 with a remainder of 177.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 177 and we're left with 177.
Bring next digit (1) of the dividend behind the 177 and repeat the process: 1771 / 853

Moving on to step 4:
853 goes into 1771 2 times with a remainder of 65.
The next digit of our result is 2. 
Result so far: 2.0
Deduct 1706 from 1771 and we're left with 65.
Include the next digit (9) from the dividend after 65, then repeat: 659 / 853

Let's proceed to step 5:
853 goes into 659 0 times with a remainder of 659.
Put 0 as the next digit of the answer. 
Result so far: 20.0
If we take 0 away from 659, we end up with 659.
Bring next digit (7) of the dividend behind the 659 and repeat the process: 6597 / 853

Moving on to step 6:
The number 853 fits into 6597 7 times, leaving a remainder of 626.
Write down 7 as next digit of the result. 
Result so far: 207.0
Subtract 5971 from 6597 to get 626.
Include the next digit (4) from the dividend after 626, then repeat: 6264 / 853

Advancing to step 7:
853 can be fit into 6264 7 times, resulting in a remainder of 293.
The next digit of our result is 7. 
Result so far: 2077.0
Deduct 5971 from 6264 and we're left with 293.
Include the next digit (7) from the dividend after 293, then repeat: 2937 / 853

On to step 8:
When dividing 2937 by 853, we get 3 with a remainder of 378.
The number 3 becomes the next digit in our result. 
Result so far: 20773.0
Deduct 2559 from 2937 and we're left with 378.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3780, and continue the process.

Advancing to step 9:
When dividing 3780 by 853, we get 4 with a remainder of 368.
The next digit of our result is 4. 
Result so far: 20773.4
Subtract 3412 from 3780 to get 368.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

Advancing to step 10:
When dividing 3680 by 853, we get 4 with a remainder of 268.
Record the quotient 4 as the next digit in the result. 
Result so far: 20773.44
Subtract 3412 from 3680 to get 268.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2680, and continue the process.

The final result is 20773.44 with a remainder of 0.268.
