We divide 153404 by 28
We want to figure out the number of times 153404 can be divided by 28.

Advancing to step 1:
When dividing 1 by 28, we get 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Take the next digit (5) from the dividend and append it to 1, then repeat: 15 / 28

Going ahead to step 2:
15 divided by 28 is 0 with a remainder of 15.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 15, we get 15.
Bring next digit (3) of the dividend behind the 15 and repeat the process: 153 / 28

Advancing to step 3:
The number 28 fits into 153 5 times, leaving a remainder of 13.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
If we subtract 140 from 153, we get 13.
Include the next digit (4) from the dividend after 13, then repeat: 134 / 28

Moving on to step 4:
134 divided by 28 is 4 with a remainder of 22.
Write down 4 as next digit of the result. 
Result so far: 54.0
Deduct 112 from 134 and we're left with 22.
Bring next digit (0) of the dividend behind the 22 and repeat the process: 220 / 28

On to step 5:
The number 28 fits into 220 7 times, leaving a remainder of 24.
The number 7 becomes the next digit in our result. 
Result so far: 547.0
Subtract 196 from 220 to get 24.
Bring next digit (4) of the dividend behind the 24 and repeat the process: 244 / 28

On to step 6:
244 divided by 28 is 8 with a remainder of 20.
Write down 8 as next digit of the result. 
Result so far: 5478.0
If we take 224 away from 244, we end up 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.

Moving on to step 7:
28 goes into 200 7 times with a remainder of 4.
Use 7 as the next digit of our solution. 
Result so far: 5478.7
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.

Let's proceed to step 8:
40 divided by 28 is 1 with a remainder of 12.
Put 1 as the next digit of the answer. 
Result so far: 5478.71
Subtract 28 from 40 to 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.

Advancing to step 9:
28 goes into 120 4 times with a remainder of 8.
The number 4 becomes the next digit in our result. 
Result so far: 5478.714
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.

Step 10:
28 goes into 80 2 times with a remainder of 24.
Record the quotient 2 as the next digit in the result. 
Result so far: 5478.7142
Subtracting 56 from 80 leaves us 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 11:
When dividing 240 by 28, we get 8 with a remainder of 16.
The next digit of our result is 8. 
Result so far: 5478.71428
Subtracting 224 from 240 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 12:
160 divided by 28 is 5 with a remainder of 20.
The next digit of our result is 5. 
Result so far: 5478.714285
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.

Going ahead to step 13:
When dividing 200 by 28, we get 7 with a remainder of 4.
The next digit of our result is 7. 
Result so far: 5478.7142857
If we subtract 196 from 200, we 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.

Let's proceed to step 14:
40 divided by 28 is 1 with a remainder of 12.
Record the quotient 1 as the next digit in the result. 
Result so far: 5478.71428571
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.

After the division, we end up with 5478.71428571 and a remainder of 1.2e-08.
