We're dividing 2999145 by 839 
We're looking to find how many times 839 goes into 2999145.

Moving on to step 1:
The number 839 fits into 2 0 times, leaving a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Take the next digit (9) from the dividend and append it to 2, then repeat: 29 / 839

Going ahead to step 2:
839 can be fit into 29 0 times, resulting in a remainder of 29.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 29, we get 29.
Append the next digit (9) from the dividend to 29 and continue with: 299 / 839

Moving on to step 3:
839 can be fit into 299 0 times, resulting in a remainder of 299.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 299, we get 299.
Include the next digit (9) from the dividend after 299, then repeat: 2999 / 839

Step 4:
When dividing 2999 by 839, we get 3 with a remainder of 482.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we subtract 2517 from 2999, we get 482.
Append the next digit (1) from the dividend to 482 and continue with: 4821 / 839

Moving on to step 5:
The number 839 fits into 4821 5 times, leaving a remainder of 626.
The number 5 becomes the next digit in our result. 
Result so far: 35.0
The remainder is 626 after subtracting 4195 from 4821.
Take the next digit (4) from the dividend and append it to 626, then repeat: 6264 / 839

Step 6:
If we divide 6264 by 839, we get 7 and a remainder of 391.
Record the quotient 7 as the next digit in the result. 
Result so far: 357.0
Deduct 5873 from 6264 and we're left with 391.
Include the next digit (5) from the dividend after 391, then repeat: 3915 / 839

Going ahead to step 7:
When dividing 3915 by 839, we get 4 with a remainder of 559.
Use 4 as the next digit of our solution. 
Result so far: 3574.0
If we subtract 3356 from 3915, we get 559.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5590, and continue the process.

On to step 8:
5590 divided by 839 is 6 with a remainder of 556.
Record the quotient 6 as the next digit in the result. 
Result so far: 3574.6
Subtracting 5034 from 5590 leaves us with 556.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5560, and continue the process.

Going ahead to step 9:
When dividing 5560 by 839, we get 6 with a remainder of 526.
Put 6 as the next digit of the answer. 
Result so far: 3574.66
If we take 5034 away from 5560, we end up with 526.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5260, and continue the process.

After the division, we end up with 3574.66 and a remainder of 0.526.
