We're dividing 126429 by 28 
We're looking to find how many times 28 goes into 126429.

On to step 1:
1 divided by 28 is 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Take the next digit (2) from the dividend and append it to 1, then repeat: 12 / 28

Going ahead to step 2:
When dividing 12 by 28, we get 0 with a remainder of 12.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 12 after subtracting 0 from 12.
Fetch the next digit (6) from the dividend, attach it to 12 and continue: 126 / 28

Moving on to step 3:
The number 28 fits into 126 4 times, leaving a remainder of 14.
Write down 4 as next digit of the result. 
Result so far: 4.0
Subtracting 112 from 126 leaves us with 14.
Grab the next digit (4) from the dividend, add it to 14, then carry on: 144 / 28

Let's proceed to step 4:
If we divide 144 by 28, we get 5 and a remainder of 4.
Use 5 as the next digit of our solution. 
Result so far: 45.0
If we subtract 140 from 144, we get 4.
Append the next digit (2) from the dividend to 4 and continue with: 42 / 28

Moving on to step 5:
The number 28 fits into 42 1 times, leaving a remainder of 14.
The number 1 becomes the next digit in our result. 
Result so far: 451.0
Deduct 28 from 42 and we're left with 14.
Take the next digit (9) from the dividend and append it to 14, then repeat: 149 / 28

Moving on to step 6:
28 can be fit into 149 5 times, resulting in a remainder of 9.
The next digit of our result is 5. 
Result so far: 4515.0
If we subtract 140 from 149, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Advancing to step 7:
28 can be fit into 90 3 times, resulting in a remainder of 6.
Record the quotient 3 as the next digit in the result. 
Result so far: 4515.3
Deduct 84 from 90 and we're left 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:
The number 28 fits into 60 2 times, leaving a remainder of 4.
The number 2 becomes the next digit in our result. 
Result so far: 4515.32
Subtract 56 from 60 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.

Step 9:
40 divided by 28 is 1 with a remainder of 12.
Put 1 as the next digit of the answer. 
Result so far: 4515.321
Deduct 28 from 40 and we're left 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.

Step 10:
28 can be fit into 120 4 times, resulting in a remainder of 8.
Put 4 as the next digit of the answer. 
Result so far: 4515.3214
Subtract 112 from 120 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 11:
28 can be fit into 80 2 times, resulting in a remainder of 24.
Record the quotient 2 as the next digit in the result. 
Result so far: 4515.32142
If we subtract 56 from 80, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 12:
The number 28 fits into 240 8 times, leaving a remainder of 16.
Write down 8 as next digit of the result. 
Result so far: 4515.321428
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:
When dividing 160 by 28, we get 5 with a remainder of 20.
Record the quotient 5 as the next digit in the result. 
Result so far: 4515.3214285
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.

Step 14:
The number 28 fits into 200 7 times, leaving a remainder of 4.
Write down 7 as next digit of the result. 
Result so far: 4515.32142857
Deduct 196 from 200 and we're left 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.

The final result is 4515.32142857 with a remainder of 4e-09.
