Let's divide 19808151 by 857
The aim is to understand the frequency of 857 in 19808151.

Advancing to step 1:
When dividing 1 by 857, we get 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Append the next digit (9) from the dividend to 1 and continue with: 19 / 857

Let's proceed to step 2:
If we divide 19 by 857, we get 0 and a remainder of 19.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 19 leaves us with 19.
Grab the next digit (8) from the dividend, add it to 19, then carry on: 198 / 857

Advancing to step 3:
The number 857 fits into 198 0 times, leaving a remainder of 198.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 198 to get 198.
Bring next digit (0) of the dividend behind the 198 and repeat the process: 1980 / 857

Let's proceed to step 4:
857 can be fit into 1980 2 times, resulting in a remainder of 266.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtracting 1714 from 1980 leaves us with 266.
Append the next digit (8) from the dividend to 266 and continue with: 2668 / 857

On to step 5:
2668 divided by 857 is 3 with a remainder of 97.
Use 3 as the next digit of our solution. 
Result so far: 23.0
If we take 2571 away from 2668, we end up with 97.
Grab the next digit (1) from the dividend, add it to 97, then carry on: 971 / 857

Step 6:
857 can be fit into 971 1 times, resulting in a remainder of 114.
The next digit of our result is 1. 
Result so far: 231.0
Subtracting 857 from 971 leaves us with 114.
Append the next digit (5) from the dividend to 114 and continue with: 1145 / 857

Advancing to step 7:
857 goes into 1145 1 times with a remainder of 288.
The next digit of our result is 1. 
Result so far: 2311.0
Deduct 857 from 1145 and we're left with 288.
Include the next digit (1) from the dividend after 288, then repeat: 2881 / 857

Advancing to step 8:
857 goes into 2881 3 times with a remainder of 310.
The next digit of our result is 3. 
Result so far: 23113.0
Subtract 2571 from 2881 to get 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

Let's proceed to step 9:
857 goes into 3100 3 times with a remainder of 529.
Put 3 as the next digit of the answer. 
Result so far: 23113.3
Subtract 2571 from 3100 to get 529.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5290, and continue the process.

Advancing to step 10:
857 goes into 5290 6 times with a remainder of 148.
The number 6 becomes the next digit in our result. 
Result so far: 23113.36
If we take 5142 away from 5290, we end up with 148.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

Moving on to step 11:
The number 857 fits into 1480 1 times, leaving a remainder of 623.
The number 1 becomes the next digit in our result. 
Result so far: 23113.361
If we subtract 857 from 1480, we get 623.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6230, and continue the process.

Let's proceed to step 12:
If we divide 6230 by 857, we get 7 and a remainder of 231.
Use 7 as the next digit of our solution. 
Result so far: 23113.3617
If we subtract 5999 from 6230, we get 231.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2310, and continue the process.

Let's proceed to step 13:
857 can be fit into 2310 2 times, resulting in a remainder of 596.
Write down 2 as next digit of the result. 
Result so far: 23113.36172
The remainder is 596 after subtracting 1714 from 2310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5960, and continue the process.

Moving on to step 14:
When dividing 5960 by 857, we get 6 with a remainder of 818.
Use 6 as the next digit of our solution. 
Result so far: 23113.361726
Deduct 5142 from 5960 and we're left with 818.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8180, and continue the process.

Moving on to step 15:
857 can be fit into 8180 9 times, resulting in a remainder of 467.
Put 9 as the next digit of the answer. 
Result so far: 23113.3617269
The remainder is 467 after subtracting 7713 from 8180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4670, and continue the process.

Going ahead to step 16:
If we divide 4670 by 857, we get 5 and a remainder of 385.
The number 5 becomes the next digit in our result. 
Result so far: 23113.36172695
If we subtract 4285 from 4670, we get 385.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3850, and continue the process.

After the division, we end up with 23113.36172695 and a remainder of 3.85e-07.
