Let's divide 15165229 by 28
Our goal is to divide 15165229 by 28.

Moving on to step 1:
If we divide 1 by 28, we get 0 and a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Bring next digit (5) of the dividend behind the 1 and repeat the process: 15 / 28

Let's proceed to step 2:
28 can be fit into 15 0 times, resulting in a remainder of 15.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 15, we end up with 15.
Include the next digit (1) from the dividend after 15, then repeat: 151 / 28

On to step 3:
151 divided by 28 is 5 with a remainder of 11.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
If we subtract 140 from 151, we get 11.
Take the next digit (6) from the dividend and append it to 11, then repeat: 116 / 28

Moving on to step 4:
When dividing 116 by 28, we get 4 with a remainder of 4.
Put 4 as the next digit of the answer. 
Result so far: 54.0
Subtract 112 from 116 to get 4.
Grab the next digit (5) from the dividend, add it to 4, then carry on: 45 / 28

Step 5:
28 can be fit into 45 1 times, resulting in a remainder of 17.
Write down 1 as next digit of the result. 
Result so far: 541.0
Deduct 28 from 45 and we're left with 17.
Bring next digit (2) of the dividend behind the 17 and repeat the process: 172 / 28

On to step 6:
If we divide 172 by 28, we get 6 and a remainder of 4.
Put 6 as the next digit of the answer. 
Result so far: 5416.0
If we take 168 away from 172, we end up with 4.
Grab the next digit (2) from the dividend, add it to 4, then carry on: 42 / 28

On to step 7:
When dividing 42 by 28, we get 1 with a remainder of 14.
Record the quotient 1 as the next digit in the result. 
Result so far: 54161.0
Deduct 28 from 42 and we're left with 14.
Append the next digit (9) from the dividend to 14 and continue with: 149 / 28

Going ahead to step 8:
If we divide 149 by 28, we get 5 and a remainder of 9.
Put 5 as the next digit of the answer. 
Result so far: 541615.0
Subtracting 140 from 149 leaves us with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Step 9:
90 divided by 28 is 3 with a remainder of 6.
The next digit of our result is 3. 
Result so far: 541615.3
The remainder is 6 after subtracting 84 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 10:
When dividing 60 by 28, we get 2 with a remainder of 4.
Record the quotient 2 as the next digit in the result. 
Result so far: 541615.32
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.

Going ahead to step 11:
The number 28 fits into 40 1 times, leaving a remainder of 12.
Write down 1 as next digit of the result. 
Result so far: 541615.321
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.

Moving on to step 12:
120 divided by 28 is 4 with a remainder of 8.
The next digit of our result is 4. 
Result so far: 541615.3214
The remainder is 8 after subtracting 112 from 120.
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 13:
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: 541615.32142
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.

Moving on to step 14:
28 goes into 240 8 times with a remainder of 16.
Write down 8 as next digit of the result. 
Result so far: 541615.321428
Subtract 224 from 240 to 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 15:
28 can be fit into 160 5 times, resulting in a remainder of 20.
The number 5 becomes the next digit in our result. 
Result so far: 541615.3214285
If we take 140 away from 160, 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.

Step 16:
28 goes into 200 7 times with a remainder of 4.
The number 7 becomes the next digit in our result. 
Result so far: 541615.32142857
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 outcome is 541615.32142857, with a leftover of 4e-09.
