429991 ÷ 28 
We're looking to find how many times 28 goes into 429991.

Advancing to step 1:
28 goes into 4 0 times with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Include the next digit (2) from the dividend after 4, then repeat: 42 / 28

Going ahead to step 2:
28 can be fit into 42 1 times, resulting in a remainder of 14.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 14 after subtracting 28 from 42.
Grab the next digit (9) from the dividend, add it to 14, then carry on: 149 / 28

Going ahead to step 3:
28 goes into 149 5 times with a remainder of 9.
Use 5 as the next digit of our solution. 
Result so far: 15.0
Subtracting 140 from 149 leaves us with 9.
Bring next digit (9) of the dividend behind the 9 and repeat the process: 99 / 28

Advancing to step 4:
99 divided by 28 is 3 with a remainder of 15.
The next digit of our result is 3. 
Result so far: 153.0
If we take 84 away from 99, we end up with 15.
Append the next digit (9) from the dividend to 15 and continue with: 159 / 28

On to step 5:
159 divided by 28 is 5 with a remainder of 19.
The number 5 becomes the next digit in our result. 
Result so far: 1535.0
The remainder is 19 after subtracting 140 from 159.
Append the next digit (1) from the dividend to 19 and continue with: 191 / 28

Moving on to step 6:
The number 28 fits into 191 6 times, leaving a remainder of 23.
Use 6 as the next digit of our solution. 
Result so far: 15356.0
If we take 168 away from 191, we end up with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Going ahead to step 7:
The number 28 fits into 230 8 times, leaving a remainder of 6.
Write down 8 as next digit of the result. 
Result so far: 15356.8
Subtracting 224 from 230 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 8:
28 can be fit into 60 2 times, resulting in a remainder of 4.
The number 2 becomes the next digit in our result. 
Result so far: 15356.82
If we take 56 away from 60, we end up 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.

Advancing to step 9:
28 goes into 40 1 times with a remainder of 12.
Put 1 as the next digit of the answer. 
Result so far: 15356.821
If we subtract 28 from 40, 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.

Step 10:
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: 15356.8214
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.

Moving on to step 11:
80 divided by 28 is 2 with a remainder of 24.
The next digit of our result is 2. 
Result so far: 15356.82142
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.

Going ahead to step 12:
If we divide 240 by 28, we get 8 and a remainder of 16.
Write down 8 as next digit of the result. 
Result so far: 15356.821428
The remainder is 16 after subtracting 224 from 240.
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 13:
If we divide 160 by 28, we get 5 and a remainder of 20.
The number 5 becomes the next digit in our result. 
Result so far: 15356.8214285
If we subtract 140 from 160, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 14:
200 divided by 28 is 7 with a remainder of 4.
Record the quotient 7 as the next digit in the result. 
Result so far: 15356.82142857
Subtract 196 from 200 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

After the division, we end up with 15356.82142857 and a remainder of 4e-09.
