We look at the division of 20843399 by 857 
We want to figure out the number of times 20843399 can be divided by 857.

Step 1:
If we divide 2 by 857, we get 0 and a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Include the next digit (0) from the dividend after 2, then repeat: 20 / 857

Going ahead to step 2:
The number 857 fits into 20 0 times, leaving a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 20 after subtracting 0 from 20.
Include the next digit (8) from the dividend after 20, then repeat: 208 / 857

Step 3:
857 goes into 208 0 times with a remainder of 208.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 208, we get 208.
Append the next digit (4) from the dividend to 208 and continue with: 2084 / 857

On to step 4:
When dividing 2084 by 857, we get 2 with a remainder of 370.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtracting 1714 from 2084 leaves us with 370.
Include the next digit (3) from the dividend after 370, then repeat: 3703 / 857

Step 5:
3703 divided by 857 is 4 with a remainder of 275.
Record the quotient 4 as the next digit in the result. 
Result so far: 24.0
Subtract 3428 from 3703 to get 275.
Grab the next digit (3) from the dividend, add it to 275, then carry on: 2753 / 857

On to step 6:
857 goes into 2753 3 times with a remainder of 182.
The next digit of our result is 3. 
Result so far: 243.0
If we take 2571 away from 2753, we end up with 182.
Bring next digit (9) of the dividend behind the 182 and repeat the process: 1829 / 857

Step 7:
When dividing 1829 by 857, we get 2 with a remainder of 115.
Write down 2 as next digit of the result. 
Result so far: 2432.0
If we take 1714 away from 1829, we end up with 115.
Fetch the next digit (9) from the dividend, attach it to 115 and continue: 1159 / 857

Step 8:
When dividing 1159 by 857, we get 1 with a remainder of 302.
Write down 1 as next digit of the result. 
Result so far: 24321.0
Subtract 857 from 1159 to get 302.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3020, and continue the process.

Going ahead to step 9:
The number 857 fits into 3020 3 times, leaving a remainder of 449.
Put 3 as the next digit of the answer. 
Result so far: 24321.3
Subtracting 2571 from 3020 leaves us with 449.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4490, and continue the process.

Let's proceed to step 10:
If we divide 4490 by 857, we get 5 and a remainder of 205.
Record the quotient 5 as the next digit in the result. 
Result so far: 24321.35
Deduct 4285 from 4490 and we're left with 205.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2050, and continue the process.

On to step 11:
If we divide 2050 by 857, we get 2 and a remainder of 336.
The next digit of our result is 2. 
Result so far: 24321.352
Subtract 1714 from 2050 to get 336.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

Let's proceed to step 12:
3360 divided by 857 is 3 with a remainder of 789.
The next digit of our result is 3. 
Result so far: 24321.3523
Deduct 2571 from 3360 and we're left with 789.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7890, and continue the process.

On to step 13:
857 goes into 7890 9 times with a remainder of 177.
Write down 9 as next digit of the result. 
Result so far: 24321.35239
Subtract 7713 from 7890 to get 177.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1770, and continue the process.

On to step 14:
When dividing 1770 by 857, we get 2 with a remainder of 56.
Use 2 as the next digit of our solution. 
Result so far: 24321.352392
The remainder is 56 after subtracting 1714 from 1770.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

On to step 15:
857 goes into 560 0 times with a remainder of 560.
The number 0 becomes the next digit in our result. 
Result so far: 24321.352392
Deduct 0 from 560 and we're left with 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

Advancing to step 16:
The number 857 fits into 5600 6 times, leaving a remainder of 458.
The number 6 becomes the next digit in our result. 
Result so far: 24321.35239206
The remainder is 458 after subtracting 5142 from 5600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4580, and continue the process.

In conclusion, the division gives 24321.35239206 with a balance of 4.58e-07.
