600172 ÷ 28 
We're looking to find how many times 28 goes into 600172.

Going ahead to step 1:
The number 28 fits into 6 0 times, leaving a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Fetch the next digit (0) from the dividend, attach it to 6 and continue: 60 / 28

Advancing to step 2:
60 divided by 28 is 2 with a remainder of 4.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we take 56 away from 60, we end up with 4.
Fetch the next digit (0) from the dividend, attach it to 4 and continue: 40 / 28

On to step 3:
The number 28 fits into 40 1 times, leaving a remainder of 12.
The next digit of our result is 1. 
Result so far: 21.0
The remainder is 12 after subtracting 28 from 40.
Include the next digit (1) from the dividend after 12, then repeat: 121 / 28

Going ahead to step 4:
28 goes into 121 4 times with a remainder of 9.
Record the quotient 4 as the next digit in the result. 
Result so far: 214.0
Deduct 112 from 121 and we're left with 9.
Fetch the next digit (7) from the dividend, attach it to 9 and continue: 97 / 28

Moving on to step 5:
The number 28 fits into 97 3 times, leaving a remainder of 13.
The number 3 becomes the next digit in our result. 
Result so far: 2143.0
Subtracting 84 from 97 leaves us with 13.
Bring next digit (2) of the dividend behind the 13 and repeat the process: 132 / 28

Advancing to step 6:
The number 28 fits into 132 4 times, leaving a remainder of 20.
The next digit of our result is 4. 
Result so far: 21434.0
Subtract 112 from 132 to 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.

Advancing to step 7:
200 divided by 28 is 7 with a remainder of 4.
The next digit of our result is 7. 
Result so far: 21434.7
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.

On to step 8:
When dividing 40 by 28, we get 1 with a remainder of 12.
Write down 1 as next digit of the result. 
Result so far: 21434.71
The remainder is 12 after subtracting 28 from 40.
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 9:
When dividing 120 by 28, we get 4 with a remainder of 8.
Put 4 as the next digit of the answer. 
Result so far: 21434.714
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.

On to step 10:
If we divide 80 by 28, we get 2 and a remainder of 24.
The number 2 becomes the next digit in our result. 
Result so far: 21434.7142
Subtract 56 from 80 to 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.

Let's proceed to step 11:
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: 21434.71428
Deduct 224 from 240 and we're left 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.

Let's proceed to step 12:
When dividing 160 by 28, we get 5 with a remainder of 20.
Use 5 as the next digit of our solution. 
Result so far: 21434.714285
Deduct 140 from 160 and we're left 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.

Going ahead to step 13:
The number 28 fits into 200 7 times, leaving a remainder of 4.
Use 7 as the next digit of our solution. 
Result so far: 21434.7142857
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.

Step 14:
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: 21434.71428571
The remainder is 12 after subtracting 28 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

In conclusion, the division gives 21434.71428571 with a balance of 1.2e-08.
