8243702 divided by 858 
Let's see how many times 858 fits into 8243702.

Step 1:
8 divided by 858 is 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Include the next digit (2) from the dividend after 8, then repeat: 82 / 858

Let's proceed to step 2:
82 divided by 858 is 0 with a remainder of 82.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 82 after subtracting 0 from 82.
Include the next digit (4) from the dividend after 82, then repeat: 824 / 858

Let's proceed to step 3:
When dividing 824 by 858, we get 0 with a remainder of 824.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 824, we get 824.
Take the next digit (3) from the dividend and append it to 824, then repeat: 8243 / 858

Moving on to step 4:
858 goes into 8243 9 times with a remainder of 521.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
If we subtract 7722 from 8243, we get 521.
Grab the next digit (7) from the dividend, add it to 521, then carry on: 5217 / 858

Let's proceed to step 5:
858 can be fit into 5217 6 times, resulting in a remainder of 69.
The number 6 becomes the next digit in our result. 
Result so far: 96.0
If we subtract 5148 from 5217, we get 69.
Append the next digit (0) from the dividend to 69 and continue with: 690 / 858

On to step 6:
If we divide 690 by 858, we get 0 and a remainder of 690.
The next digit of our result is 0. 
Result so far: 960.0
If we take 0 away from 690, we end up with 690.
Bring next digit (2) of the dividend behind the 690 and repeat the process: 6902 / 858

Advancing to step 7:
858 can be fit into 6902 8 times, resulting in a remainder of 38.
Use 8 as the next digit of our solution. 
Result so far: 9608.0
If we subtract 6864 from 6902, we get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

On to step 8:
858 can be fit into 380 0 times, resulting in a remainder of 380.
The number 0 becomes the next digit in our result. 
Result so far: 9608.0
The remainder is 380 after subtracting 0 from 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Moving on to step 9:
858 can be fit into 3800 4 times, resulting in a remainder of 368.
The number 4 becomes the next digit in our result. 
Result so far: 9608.04
If we subtract 3432 from 3800, we 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.

Going ahead to step 10:
If we divide 3680 by 858, we get 4 and a remainder of 248.
Put 4 as the next digit of the answer. 
Result so far: 9608.044
The remainder is 248 after subtracting 3432 from 3680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

After the division, we end up with 9608.044 and a remainder of 0.0248.
