We're dividing 36172 by 30 
We want to divide 36172 by 30.

Advancing to step 1:
The number 30 fits into 3 0 times, leaving a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Include the next digit (6) from the dividend after 3, then repeat: 36 / 30

Step 2:
30 goes into 36 1 times with a remainder of 6.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 30 from 36 and we're left with 6.
Grab the next digit (1) from the dividend, add it to 6, then carry on: 61 / 30

Moving on to step 3:
30 goes into 61 2 times with a remainder of 1.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
The remainder is 1 after subtracting 60 from 61.
Fetch the next digit (7) from the dividend, attach it to 1 and continue: 17 / 30

Advancing to step 4:
30 can be fit into 17 0 times, resulting in a remainder of 17.
The next digit of our result is 0. 
Result so far: 120.0
The remainder is 17 after subtracting 0 from 17.
Fetch the next digit (2) from the dividend, attach it to 17 and continue: 172 / 30

Let's proceed to step 5:
If we divide 172 by 30, we get 5 and a remainder of 22.
Put 5 as the next digit of the answer. 
Result so far: 1205.0
Subtracting 150 from 172 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 6:
When dividing 220 by 30, we get 7 with a remainder of 10.
Use 7 as the next digit of our solution. 
Result so far: 1205.7
Subtracting 210 from 220 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 7:
If we divide 100 by 30, we get 3 and a remainder of 10.
The number 3 becomes the next digit in our result. 
Result so far: 1205.73
Deduct 90 from 100 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 8:
The number 30 fits into 100 3 times, leaving a remainder of 10.
Write down 3 as next digit of the result. 
Result so far: 1205.733
If we take 90 away from 100, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

After the division, we end up with 1205.733 and a remainder of 0.001.
