3349011 ÷ 858 
Let's see how many times 858 fits into 3349011.

Advancing to step 1:
The number 858 fits into 3 0 times, leaving a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Take the next digit (3) from the dividend and append it to 3, then repeat: 33 / 858

On to step 2:
The number 858 fits into 33 0 times, leaving a remainder of 33.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 33 leaves us with 33.
Bring next digit (4) of the dividend behind the 33 and repeat the process: 334 / 858

Let's proceed to step 3:
858 goes into 334 0 times with a remainder of 334.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 334 after subtracting 0 from 334.
Include the next digit (9) from the dividend after 334, then repeat: 3349 / 858

Moving on to step 4:
The number 858 fits into 3349 3 times, leaving a remainder of 775.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
The remainder is 775 after subtracting 2574 from 3349.
Fetch the next digit (0) from the dividend, attach it to 775 and continue: 7750 / 858

On to step 5:
If we divide 7750 by 858, we get 9 and a remainder of 28.
The number 9 becomes the next digit in our result. 
Result so far: 39.0
Deduct 7722 from 7750 and we're left with 28.
Grab the next digit (1) from the dividend, add it to 28, then carry on: 281 / 858

Moving on to step 6:
858 goes into 281 0 times with a remainder of 281.
The next digit of our result is 0. 
Result so far: 390.0
If we subtract 0 from 281, we get 281.
Append the next digit (1) from the dividend to 281 and continue with: 2811 / 858

Moving on to step 7:
858 goes into 2811 3 times with a remainder of 237.
Write down 3 as next digit of the result. 
Result so far: 3903.0
Subtract 2574 from 2811 to get 237.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2370, and continue the process.

Let's proceed to step 8:
When dividing 2370 by 858, we get 2 with a remainder of 654.
Put 2 as the next digit of the answer. 
Result so far: 3903.2
Deduct 1716 from 2370 and we're left with 654.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6540, and continue the process.

Let's proceed to step 9:
The number 858 fits into 6540 7 times, leaving a remainder of 534.
Write down 7 as next digit of the result. 
Result so far: 3903.27
Deduct 6006 from 6540 and we're left with 534.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5340, and continue the process.

Going ahead to step 10:
When dividing 5340 by 858, we get 6 with a remainder of 192.
The number 6 becomes the next digit in our result. 
Result so far: 3903.276
Subtracting 5148 from 5340 leaves us with 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

Moving on to step 11:
858 goes into 1920 2 times with a remainder of 204.
The next digit of our result is 2. 
Result so far: 3903.2762
Subtract 1716 from 1920 to get 204.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2040, and continue the process.

Advancing to step 12:
If we divide 2040 by 858, we get 2 and a remainder of 324.
The number 2 becomes the next digit in our result. 
Result so far: 3903.27622
If we take 1716 away from 2040, we end up with 324.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3240, and continue the process.

The final result is 3903.27622 with a remainder of 0.000324.
