173039 divided by 43 
We're looking to find how many times 43 goes into 173039.

On to step 1:
The number 43 fits into 1 0 times, leaving a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Fetch the next digit (7) from the dividend, attach it to 1 and continue: 17 / 43

Advancing to step 2:
The number 43 fits into 17 0 times, leaving a remainder of 17.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 17, we get 17.
Fetch the next digit (3) from the dividend, attach it to 17 and continue: 173 / 43

Step 3:
When dividing 173 by 43, we get 4 with a remainder of 1.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
The remainder is 1 after subtracting 172 from 173.
Take the next digit (0) from the dividend and append it to 1, then repeat: 10 / 43

On to step 4:
When dividing 10 by 43, we get 0 with a remainder of 10.
The next digit of our result is 0. 
Result so far: 40.0
If we subtract 0 from 10, we get 10.
Append the next digit (3) from the dividend to 10 and continue with: 103 / 43

Step 5:
When dividing 103 by 43, we get 2 with a remainder of 17.
Put 2 as the next digit of the answer. 
Result so far: 402.0
Subtract 86 from 103 to get 17.
Include the next digit (9) from the dividend after 17, then repeat: 179 / 43

Step 6:
43 goes into 179 4 times with a remainder of 7.
Use 4 as the next digit of our solution. 
Result so far: 4024.0
If we take 172 away from 179, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 7:
43 can be fit into 70 1 times, resulting in a remainder of 27.
Use 1 as the next digit of our solution. 
Result so far: 4024.1
Subtracting 43 from 70 leaves us with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

On to step 8:
When dividing 270 by 43, we get 6 with a remainder of 12.
The number 6 becomes the next digit in our result. 
Result so far: 4024.16
Deduct 258 from 270 and we're left 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.

Step 9:
The number 43 fits into 120 2 times, leaving a remainder of 34.
Write down 2 as next digit of the result. 
Result so far: 4024.162
Deduct 86 from 120 and we're left with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Step 10:
43 can be fit into 340 7 times, resulting in a remainder of 39.
Write down 7 as next digit of the result. 
Result so far: 4024.1627
The remainder is 39 after subtracting 301 from 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Step 11:
If we divide 390 by 43, we get 9 and a remainder of 3.
Write down 9 as next digit of the result. 
Result so far: 4024.16279
If we take 387 away from 390, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 12:
If we divide 30 by 43, we get 0 and a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 4024.16279
Deduct 0 from 30 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 13:
If we divide 300 by 43, we get 6 and a remainder of 42.
Write down 6 as next digit of the result. 
Result so far: 4024.1627906
Subtract 258 from 300 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Going ahead to step 14:
When dividing 420 by 43, we get 9 with a remainder of 33.
The next digit of our result is 9. 
Result so far: 4024.16279069
If we take 387 away from 420, we end up with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

After the division, we end up with 4024.16279069 and a remainder of 3.3e-08.
