349990 ÷ 28 
Our goal is to divide 349990 by 28.

Advancing to step 1:
3 divided by 28 is 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Append the next digit (4) from the dividend to 3 and continue with: 34 / 28

Moving on to step 2:
The number 28 fits into 34 1 times, leaving a remainder of 6.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 28 from 34 and we're left with 6.
Bring next digit (9) of the dividend behind the 6 and repeat the process: 69 / 28

Moving on to step 3:
28 goes into 69 2 times with a remainder of 13.
The next digit of our result is 2. 
Result so far: 12.0
If we subtract 56 from 69, we get 13.
Fetch the next digit (9) from the dividend, attach it to 13 and continue: 139 / 28

Moving on to step 4:
If we divide 139 by 28, we get 4 and a remainder of 27.
Put 4 as the next digit of the answer. 
Result so far: 124.0
Deduct 112 from 139 and we're left with 27.
Take the next digit (9) from the dividend and append it to 27, then repeat: 279 / 28

Step 5:
If we divide 279 by 28, we get 9 and a remainder of 27.
The number 9 becomes the next digit in our result. 
Result so far: 1249.0
Deduct 252 from 279 and we're left with 27.
Grab the next digit (0) from the dividend, add it to 27, then carry on: 270 / 28

Moving on to step 6:
270 divided by 28 is 9 with a remainder of 18.
Record the quotient 9 as the next digit in the result. 
Result so far: 12499.0
If we subtract 252 from 270, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 7:
28 goes into 180 6 times with a remainder of 12.
Record the quotient 6 as the next digit in the result. 
Result so far: 12499.6
If we subtract 168 from 180, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 8:
When dividing 120 by 28, we get 4 with a remainder of 8.
Record the quotient 4 as the next digit in the result. 
Result so far: 12499.64
If we take 112 away from 120, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 9:
When dividing 80 by 28, we get 2 with a remainder of 24.
Put 2 as the next digit of the answer. 
Result so far: 12499.642
Deduct 56 from 80 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 10:
28 can be fit into 240 8 times, resulting in a remainder of 16.
Record the quotient 8 as the next digit in the result. 
Result so far: 12499.6428
If we subtract 224 from 240, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 11:
160 divided by 28 is 5 with a remainder of 20.
Write down 5 as next digit of the result. 
Result so far: 12499.64285
Subtracting 140 from 160 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 12:
28 can be fit into 200 7 times, resulting in a remainder of 4.
The next digit of our result is 7. 
Result so far: 12499.642857
Subtracting 196 from 200 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 13:
28 can be fit into 40 1 times, resulting in a remainder of 12.
Use 1 as the next digit of our solution. 
Result so far: 12499.6428571
If we take 28 away from 40, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 14:
The number 28 fits into 120 4 times, leaving a remainder of 8.
Use 4 as the next digit of our solution. 
Result so far: 12499.64285714
Subtracting 112 from 120 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Our division results in 12499.64285714 with a remaining 8e-09.
