We're dividing 2993634 by 858 
Our goal is to divide 2993634 by 858.

Advancing to step 1:
858 can be fit into 2 0 times, resulting in a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Include the next digit (9) from the dividend after 2, then repeat: 29 / 858

Advancing to step 2:
When dividing 29 by 858, we get 0 with a remainder of 29.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 29, we end up with 29.
Grab the next digit (9) from the dividend, add it to 29, then carry on: 299 / 858

Step 3:
If we divide 299 by 858, we get 0 and a remainder of 299.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 299 after subtracting 0 from 299.
Take the next digit (3) from the dividend and append it to 299, then repeat: 2993 / 858

On to step 4:
858 can be fit into 2993 3 times, resulting in a remainder of 419.
Write down 3 as next digit of the result. 
Result so far: 3.0
If we take 2574 away from 2993, we end up with 419.
Fetch the next digit (6) from the dividend, attach it to 419 and continue: 4196 / 858

Moving on to step 5:
858 can be fit into 4196 4 times, resulting in a remainder of 764.
The next digit of our result is 4. 
Result so far: 34.0
If we subtract 3432 from 4196, we get 764.
Include the next digit (3) from the dividend after 764, then repeat: 7643 / 858

On to step 6:
858 goes into 7643 8 times with a remainder of 779.
The next digit of our result is 8. 
Result so far: 348.0
Subtracting 6864 from 7643 leaves us with 779.
Append the next digit (4) from the dividend to 779 and continue with: 7794 / 858

Going ahead to step 7:
When dividing 7794 by 858, we get 9 with a remainder of 72.
The next digit of our result is 9. 
Result so far: 3489.0
Subtracting 7722 from 7794 leaves us with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

On to step 8:
When dividing 720 by 858, we get 0 with a remainder of 720.
Write down 0 as next digit of the result. 
Result so far: 3489.0
Subtract 0 from 720 to get 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7200, and continue the process.

Going ahead to step 9:
858 can be fit into 7200 8 times, resulting in a remainder of 336.
The next digit of our result is 8. 
Result so far: 3489.08
Deduct 6864 from 7200 and we're left with 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 10:
3360 divided by 858 is 3 with a remainder of 786.
The number 3 becomes the next digit in our result. 
Result so far: 3489.083
Deduct 2574 from 3360 and we're left with 786.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7860, and continue the process.

On to step 11:
If we divide 7860 by 858, we get 9 and a remainder of 138.
The number 9 becomes the next digit in our result. 
Result so far: 3489.0839
If we subtract 7722 from 7860, we get 138.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1380, and continue the process.

Let's proceed to step 12:
858 goes into 1380 1 times with a remainder of 522.
Use 1 as the next digit of our solution. 
Result so far: 3489.08391
Subtract 858 from 1380 to get 522.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5220, and continue the process.

Moving on to step 13:
5220 divided by 858 is 6 with a remainder of 72.
The next digit of our result is 6. 
Result so far: 3489.083916
If we take 5148 away from 5220, we end up with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Let's proceed to step 14:
If we divide 720 by 858, we get 0 and a remainder of 720.
Write down 0 as next digit of the result. 
Result so far: 3489.083916
If we subtract 0 from 720, we get 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7200, and continue the process.

Moving on to step 15:
If we divide 7200 by 858, we get 8 and a remainder of 336.
The next digit of our result is 8. 
Result so far: 3489.08391608
Subtract 6864 from 7200 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.

After the division, we end up with 3489.08391608 and a remainder of 3.36e-07.
