We look at the division of 180431 by 43 
We're looking to find how many times 43 goes into 180431.

Moving on 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
Deduct 0 from 1 and we're left with 1.
Bring next digit (8) of the dividend behind the 1 and repeat the process: 18 / 43

Step 2:
When dividing 18 by 43, we get 0 with a remainder of 18.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 18, we end up with 18.
Grab the next digit (0) from the dividend, add it to 18, then carry on: 180 / 43

Going ahead to step 3:
180 divided by 43 is 4 with a remainder of 8.
Put 4 as the next digit of the answer. 
Result so far: 4.0
If we subtract 172 from 180, we get 8.
Bring next digit (4) of the dividend behind the 8 and repeat the process: 84 / 43

Let's proceed to step 4:
If we divide 84 by 43, we get 1 and a remainder of 41.
The next digit of our result is 1. 
Result so far: 41.0
If we subtract 43 from 84, we get 41.
Bring next digit (3) of the dividend behind the 41 and repeat the process: 413 / 43

Advancing to step 5:
When dividing 413 by 43, we get 9 with a remainder of 26.
Put 9 as the next digit of the answer. 
Result so far: 419.0
If we subtract 387 from 413, we get 26.
Grab the next digit (1) from the dividend, add it to 26, then carry on: 261 / 43

Let's proceed to step 6:
261 divided by 43 is 6 with a remainder of 3.
The next digit of our result is 6. 
Result so far: 4196.0
Subtract 258 from 261 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 7:
43 goes into 30 0 times with a remainder of 30.
The next digit of our result is 0. 
Result so far: 4196.0
If we take 0 away from 30, we end up 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.

On to step 8:
43 can be fit into 300 6 times, resulting in a remainder of 42.
Write down 6 as next digit of the result. 
Result so far: 4196.06
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 9:
If we divide 420 by 43, we get 9 and a remainder of 33.
Use 9 as the next digit of our solution. 
Result so far: 4196.069
If we subtract 387 from 420, we get 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

On to step 10:
330 divided by 43 is 7 with a remainder of 29.
Put 7 as the next digit of the answer. 
Result so far: 4196.0697
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.

Advancing to step 11:
43 can be fit into 290 6 times, resulting in a remainder of 32.
Write down 6 as next digit of the result. 
Result so far: 4196.06976
If we subtract 258 from 290, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 12:
43 can be fit into 320 7 times, resulting in a remainder of 19.
Write down 7 as next digit of the result. 
Result so far: 4196.069767
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.

On to step 13:
43 can be fit into 190 4 times, resulting in a remainder of 18.
Record the quotient 4 as the next digit in the result. 
Result so far: 4196.0697674
Subtract 172 from 190 to 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.

Moving on to step 14:
When dividing 180 by 43, we get 4 with a remainder of 8.
The next digit of our result is 4. 
Result so far: 4196.06976744
If we subtract 172 from 180, we 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.

Our division results in 4196.06976744 with a remaining 8e-09.
