We look at the division of 173212 by 23 
We're looking to find how many times 23 goes into 173212.

Going ahead to step 1:
23 can be fit into 1 0 times, resulting in 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.
Grab the next digit (7) from the dividend, add it to 1, then carry on: 17 / 23

Let's proceed to step 2:
When dividing 17 by 23, we get 0 with a remainder of 17.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 17, we get 17.
Take the next digit (3) from the dividend and append it to 17, then repeat: 173 / 23

Let's proceed to step 3:
When dividing 173 by 23, we get 7 with a remainder of 12.
Use 7 as the next digit of our solution. 
Result so far: 7.0
Subtract 161 from 173 to get 12.
Bring next digit (2) of the dividend behind the 12 and repeat the process: 122 / 23

Step 4:
23 can be fit into 122 5 times, resulting in a remainder of 7.
The next digit of our result is 5. 
Result so far: 75.0
The remainder is 7 after subtracting 115 from 122.
Include the next digit (1) from the dividend after 7, then repeat: 71 / 23

Moving on to step 5:
71 divided by 23 is 3 with a remainder of 2.
Record the quotient 3 as the next digit in the result. 
Result so far: 753.0
The remainder is 2 after subtracting 69 from 71.
Append the next digit (2) from the dividend to 2 and continue with: 22 / 23

Let's proceed to step 6:
23 goes into 22 0 times with a remainder of 22.
Write down 0 as next digit of the result. 
Result so far: 7530.0
Deduct 0 from 22 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.

Advancing to step 7:
The number 23 fits into 220 9 times, leaving a remainder of 13.
Use 9 as the next digit of our solution. 
Result so far: 7530.9
Subtract 207 from 220 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Going ahead to step 8:
130 divided by 23 is 5 with a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 7530.95
If we subtract 115 from 130, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 9:
The number 23 fits into 150 6 times, leaving a remainder of 12.
The next digit of our result is 6. 
Result so far: 7530.956
Subtracting 138 from 150 leaves us 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.

Advancing to step 10:
23 can be fit into 120 5 times, resulting in a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 7530.9565
Deduct 115 from 120 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 11:
23 can be fit into 50 2 times, resulting in a remainder of 4.
Use 2 as the next digit of our solution. 
Result so far: 7530.95652
The remainder is 4 after subtracting 46 from 50.
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 12:
When dividing 40 by 23, we get 1 with a remainder of 17.
Record the quotient 1 as the next digit in the result. 
Result so far: 7530.956521
The remainder is 17 after subtracting 23 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Let's proceed to step 13:
When dividing 170 by 23, we get 7 with a remainder of 9.
Use 7 as the next digit of our solution. 
Result so far: 7530.9565217
Subtract 161 from 170 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Going ahead to step 14:
90 divided by 23 is 3 with a remainder of 21.
Use 3 as the next digit of our solution. 
Result so far: 7530.95652173
If we take 69 away from 90, we end up with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Our division results in 7530.95652173 with a remaining 2.1e-08.
