We look at the division of 173160 by 43 
We want to figure out the number of times 173160 can be divided by 43.

Going ahead to step 1:
If we divide 1 by 43, we get 0 and a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Include the next digit (7) from the dividend after 1, then repeat: 17 / 43

On to step 2:
43 goes into 17 0 times with a remainder of 17.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 17 after subtracting 0 from 17.
Bring next digit (3) of the dividend behind the 17 and repeat the process: 173 / 43

Moving on to step 3:
The number 43 fits into 173 4 times, leaving a remainder of 1.
The next digit of our result is 4. 
Result so far: 4.0
Deduct 172 from 173 and we're left with 1.
Include the next digit (1) from the dividend after 1, then repeat: 11 / 43

Moving on to step 4:
11 divided by 43 is 0 with a remainder of 11.
The number 0 becomes the next digit in our result. 
Result so far: 40.0
Subtract 0 from 11 to get 11.
Fetch the next digit (6) from the dividend, attach it to 11 and continue: 116 / 43

Moving on to step 5:
The number 43 fits into 116 2 times, leaving a remainder of 30.
The number 2 becomes the next digit in our result. 
Result so far: 402.0
If we take 86 away from 116, we end up with 30.
Append the next digit (0) from the dividend to 30 and continue with: 300 / 43

Advancing to step 6:
When dividing 300 by 43, we get 6 with a remainder of 42.
The number 6 becomes the next digit in our result. 
Result so far: 4026.0
If we subtract 258 from 300, we 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.

Moving on to step 7:
The number 43 fits into 420 9 times, leaving a remainder of 33.
Write down 9 as next digit of the result. 
Result so far: 4026.9
Deduct 387 from 420 and we're left 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.

Advancing to step 8:
When dividing 330 by 43, we get 7 with a remainder of 29.
Record the quotient 7 as the next digit in the result. 
Result so far: 4026.97
If we take 301 away from 330, we end up with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Step 9:
If we divide 290 by 43, we get 6 and a remainder of 32.
Record the quotient 6 as the next digit in the result. 
Result so far: 4026.976
Deduct 258 from 290 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 10:
320 divided by 43 is 7 with a remainder of 19.
Write down 7 as next digit of the result. 
Result so far: 4026.9767
If we take 301 away from 320, we end up with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Step 11:
When dividing 190 by 43, we get 4 with a remainder of 18.
Put 4 as the next digit of the answer. 
Result so far: 4026.97674
If we subtract 172 from 190, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 12:
When dividing 180 by 43, we get 4 with a remainder of 8.
Write down 4 as next digit of the result. 
Result so far: 4026.976744
Subtract 172 from 180 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

In conclusion, the division gives 4026.976744 with a balance of 8e-07.
