We look at the division of 879386 by 43 
Our goal is to divide 879386 by 43.

Step 1:
43 goes into 8 0 times with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Fetch the next digit (7) from the dividend, attach it to 8 and continue: 87 / 43

Moving on to step 2:
43 goes into 87 2 times with a remainder of 1.
The next digit of our result is 2. 
Result so far: 2.0
Subtracting 86 from 87 leaves us with 1.
Take the next digit (9) from the dividend and append it to 1, then repeat: 19 / 43

Step 3:
The number 43 fits into 19 0 times, leaving a remainder of 19.
The number 0 becomes the next digit in our result. 
Result so far: 20.0
Subtracting 0 from 19 leaves us with 19.
Include the next digit (3) from the dividend after 19, then repeat: 193 / 43

Going ahead to step 4:
193 divided by 43 is 4 with a remainder of 21.
The number 4 becomes the next digit in our result. 
Result so far: 204.0
Deduct 172 from 193 and we're left with 21.
Grab the next digit (8) from the dividend, add it to 21, then carry on: 218 / 43

Let's proceed to step 5:
When dividing 218 by 43, we get 5 with a remainder of 3.
Write down 5 as next digit of the result. 
Result so far: 2045.0
The remainder is 3 after subtracting 215 from 218.
Bring next digit (6) of the dividend behind the 3 and repeat the process: 36 / 43

Moving on to step 6:
The number 43 fits into 36 0 times, leaving a remainder of 36.
Record the quotient 0 as the next digit in the result. 
Result so far: 20450.0
If we subtract 0 from 36, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 7:
The number 43 fits into 360 8 times, leaving a remainder of 16.
The next digit of our result is 8. 
Result so far: 20450.8
If we subtract 344 from 360, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 8:
If we divide 160 by 43, we get 3 and a remainder of 31.
Put 3 as the next digit of the answer. 
Result so far: 20450.83
The remainder is 31 after subtracting 129 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Step 9:
43 can be fit into 310 7 times, resulting in a remainder of 9.
The number 7 becomes the next digit in our result. 
Result so far: 20450.837
If we subtract 301 from 310, we 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 10:
If we divide 90 by 43, we get 2 and a remainder of 4.
The number 2 becomes the next digit in our result. 
Result so far: 20450.8372
Subtract 86 from 90 to get 4.
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 11:
The number 43 fits into 40 0 times, leaving a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 20450.8372
Subtracting 0 from 40 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 12:
400 divided by 43 is 9 with a remainder of 13.
Use 9 as the next digit of our solution. 
Result so far: 20450.837209
If we take 387 away from 400, we end up with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

On to step 13:
When dividing 130 by 43, we get 3 with a remainder of 1.
Record the quotient 3 as the next digit in the result. 
Result so far: 20450.8372093
Deduct 129 from 130 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 14:
43 goes into 10 0 times with a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 20450.8372093
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Our division results in 20450.8372093 with a remaining 1e-08.
