We look at the division of 9992103 by 857 
The aim is to understand the frequency of 857 in 9992103.

Step 1:
If we divide 9 by 857, we get 0 and a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Include the next digit (9) from the dividend after 9, then repeat: 99 / 857

On to step 2:
857 can be fit into 99 0 times, resulting in a remainder of 99.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 99 after subtracting 0 from 99.
Append the next digit (9) from the dividend to 99 and continue with: 999 / 857

Moving on to step 3:
999 divided by 857 is 1 with a remainder of 142.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 857 from 999 leaves us with 142.
Include the next digit (2) from the dividend after 142, then repeat: 1422 / 857

Advancing to step 4:
857 goes into 1422 1 times with a remainder of 565.
Use 1 as the next digit of our solution. 
Result so far: 11.0
The remainder is 565 after subtracting 857 from 1422.
Include the next digit (1) from the dividend after 565, then repeat: 5651 / 857

On to step 5:
857 can be fit into 5651 6 times, resulting in a remainder of 509.
Write down 6 as next digit of the result. 
Result so far: 116.0
Subtracting 5142 from 5651 leaves us with 509.
Bring next digit (0) of the dividend behind the 509 and repeat the process: 5090 / 857

Step 6:
857 can be fit into 5090 5 times, resulting in a remainder of 805.
Record the quotient 5 as the next digit in the result. 
Result so far: 1165.0
The remainder is 805 after subtracting 4285 from 5090.
Grab the next digit (3) from the dividend, add it to 805, then carry on: 8053 / 857

Step 7:
If we divide 8053 by 857, we get 9 and a remainder of 340.
Use 9 as the next digit of our solution. 
Result so far: 11659.0
Deduct 7713 from 8053 and we're left with 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Moving on to step 8:
857 goes into 3400 3 times with a remainder of 829.
Use 3 as the next digit of our solution. 
Result so far: 11659.3
If we subtract 2571 from 3400, we get 829.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8290, and continue the process.

Moving on to step 9:
857 goes into 8290 9 times with a remainder of 577.
The next digit of our result is 9. 
Result so far: 11659.39
The remainder is 577 after subtracting 7713 from 8290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5770, and continue the process.

Advancing to step 10:
When dividing 5770 by 857, we get 6 with a remainder of 628.
The number 6 becomes the next digit in our result. 
Result so far: 11659.396
If we take 5142 away from 5770, we end up with 628.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6280, and continue the process.

Let's proceed to step 11:
The number 857 fits into 6280 7 times, leaving a remainder of 281.
Record the quotient 7 as the next digit in the result. 
Result so far: 11659.3967
The remainder is 281 after subtracting 5999 from 6280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2810, and continue the process.

Moving on to step 12:
If we divide 2810 by 857, we get 3 and a remainder of 239.
Put 3 as the next digit of the answer. 
Result so far: 11659.39673
If we subtract 2571 from 2810, we get 239.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2390, and continue the process.

Step 13:
857 goes into 2390 2 times with a remainder of 676.
Record the quotient 2 as the next digit in the result. 
Result so far: 11659.396732
If we subtract 1714 from 2390, we get 676.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6760, and continue the process.

Going ahead to step 14:
The number 857 fits into 6760 7 times, leaving a remainder of 761.
The number 7 becomes the next digit in our result. 
Result so far: 11659.3967327
Deduct 5999 from 6760 and we're left with 761.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7610, and continue the process.

Step 15:
The number 857 fits into 7610 8 times, leaving a remainder of 754.
Use 8 as the next digit of our solution. 
Result so far: 11659.39673278
If we take 6856 away from 7610, we end up with 754.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7540, and continue the process.

In conclusion, the division gives 11659.39673278 with a balance of 7.54e-07.
