We look at the division of 172138 by 36 
We want to divide 172138 by 36.

On to step 1:
36 goes into 1 0 times with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Take the next digit (7) from the dividend and append it to 1, then repeat: 17 / 36

Moving on to step 2:
36 can be fit into 17 0 times, resulting in a remainder of 17.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 17, we get 17.
Grab the next digit (2) from the dividend, add it to 17, then carry on: 172 / 36

Going ahead to step 3:
172 divided by 36 is 4 with a remainder of 28.
The next digit of our result is 4. 
Result so far: 4.0
Subtracting 144 from 172 leaves us with 28.
Take the next digit (1) from the dividend and append it to 28, then repeat: 281 / 36

Step 4:
36 can be fit into 281 7 times, resulting in a remainder of 29.
Write down 7 as next digit of the result. 
Result so far: 47.0
If we subtract 252 from 281, we get 29.
Fetch the next digit (3) from the dividend, attach it to 29 and continue: 293 / 36

On to step 5:
When dividing 293 by 36, we get 8 with a remainder of 5.
Use 8 as the next digit of our solution. 
Result so far: 478.0
If we take 288 away from 293, we end up with 5.
Include the next digit (8) from the dividend after 5, then repeat: 58 / 36

Advancing to step 6:
36 can be fit into 58 1 times, resulting in a remainder of 22.
The number 1 becomes the next digit in our result. 
Result so far: 4781.0
Deduct 36 from 58 and we're left 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.

Going ahead to step 7:
When dividing 220 by 36, we get 6 with a remainder of 4.
The number 6 becomes the next digit in our result. 
Result so far: 4781.6
Subtract 216 from 220 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.

On to step 8:
When dividing 40 by 36, we get 1 with a remainder of 4.
The number 1 becomes the next digit in our result. 
Result so far: 4781.61
The remainder is 4 after subtracting 36 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 9:
The number 36 fits into 40 1 times, leaving a remainder of 4.
Use 1 as the next digit of our solution. 
Result so far: 4781.611
Subtracting 36 from 40 leaves us 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 quotient of the division is 4781.611, and the remainder is 0.0004.
