We're dividing 861673 by 43 
We want to figure out the number of times 861673 can be divided by 43.

Advancing to step 1:
8 divided by 43 is 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Take the next digit (6) from the dividend and append it to 8, then repeat: 86 / 43

Moving on to step 2:
If we divide 86 by 43, we get 2 and a remainder of 0.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtracting 86 from 86 leaves us with 0.
Take the next digit (1) from the dividend and append it to 0, then repeat: 1 / 43

On to step 3:
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: 20.0
If we subtract 0 from 1, we get 1.
Include the next digit (6) from the dividend after 1, then repeat: 16 / 43

Let's proceed to step 4:
43 goes into 16 0 times with a remainder of 16.
Use 0 as the next digit of our solution. 
Result so far: 200.0
Subtract 0 from 16 to get 16.
Bring next digit (7) of the dividend behind the 16 and repeat the process: 167 / 43

Going ahead to step 5:
43 can be fit into 167 3 times, resulting in a remainder of 38.
Put 3 as the next digit of the answer. 
Result so far: 2003.0
If we take 129 away from 167, we end up with 38.
Bring next digit (3) of the dividend behind the 38 and repeat the process: 383 / 43

Going ahead to step 6:
If we divide 383 by 43, we get 8 and a remainder of 39.
The next digit of our result is 8. 
Result so far: 20038.0
The remainder is 39 after subtracting 344 from 383.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Step 7:
390 divided by 43 is 9 with a remainder of 3.
Write down 9 as next digit of the result. 
Result so far: 20038.9
Subtract 387 from 390 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.

Advancing to step 8:
30 divided by 43 is 0 with a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 20038.9
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.

Step 9:
43 can be fit into 300 6 times, resulting in a remainder of 42.
Put 6 as the next digit of the answer. 
Result so far: 20038.906
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.

Step 10:
When dividing 420 by 43, we get 9 with a remainder of 33.
Write down 9 as next digit of the result. 
Result so far: 20038.9069
The remainder is 33 after subtracting 387 from 420.
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 11:
The number 43 fits into 330 7 times, leaving a remainder of 29.
The number 7 becomes the next digit in our result. 
Result so far: 20038.90697
Subtracting 301 from 330 leaves us 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 12:
When dividing 290 by 43, we get 6 with a remainder of 32.
Use 6 as the next digit of our solution. 
Result so far: 20038.906976
Subtract 258 from 290 to 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.

Let's proceed to step 13:
320 divided by 43 is 7 with a remainder of 19.
Record the quotient 7 as the next digit in the result. 
Result so far: 20038.9069767
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.

Advancing to step 14:
If we divide 190 by 43, we get 4 and a remainder of 18.
The number 4 becomes the next digit in our result. 
Result so far: 20038.90697674
If we take 172 away from 190, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

After the division, we end up with 20038.90697674 and a remainder of 1.8e-08.
