We look at the division of 820390 by 43 
We want to figure out the number of times 820390 can be divided by 43.

Let's proceed to step 1:
43 goes into 8 0 times with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Grab the next digit (2) from the dividend, add it to 8, then carry on: 82 / 43

Moving on to step 2:
The number 43 fits into 82 1 times, leaving a remainder of 39.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 43 from 82 leaves us with 39.
Bring next digit (0) of the dividend behind the 39 and repeat the process: 390 / 43

Going ahead to step 3:
43 can be fit into 390 9 times, resulting in a remainder of 3.
The next digit of our result is 9. 
Result so far: 19.0
The remainder is 3 after subtracting 387 from 390.
Take the next digit (3) from the dividend and append it to 3, then repeat: 33 / 43

Moving on to step 4:
When dividing 33 by 43, we get 0 with a remainder of 33.
The number 0 becomes the next digit in our result. 
Result so far: 190.0
If we take 0 away from 33, we end up with 33.
Grab the next digit (9) from the dividend, add it to 33, then carry on: 339 / 43

Moving on to step 5:
When dividing 339 by 43, we get 7 with a remainder of 38.
Write down 7 as next digit of the result. 
Result so far: 1907.0
If we subtract 301 from 339, we get 38.
Include the next digit (0) from the dividend after 38, then repeat: 380 / 43

Step 6:
The number 43 fits into 380 8 times, leaving a remainder of 36.
Put 8 as the next digit of the answer. 
Result so far: 19078.0
If we subtract 344 from 380, 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.

Moving on to step 7:
360 divided by 43 is 8 with a remainder of 16.
The number 8 becomes the next digit in our result. 
Result so far: 19078.8
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.

Going ahead to step 8:
The number 43 fits into 160 3 times, leaving a remainder of 31.
The next digit of our result is 3. 
Result so far: 19078.83
If we subtract 129 from 160, we get 31.
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:
When dividing 310 by 43, we get 7 with a remainder of 9.
The next digit of our result is 7. 
Result so far: 19078.837
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.

Moving on to step 10:
90 divided by 43 is 2 with a remainder of 4.
The number 2 becomes the next digit in our result. 
Result so far: 19078.8372
If we take 86 away from 90, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 11:
43 goes into 40 0 times with a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 19078.8372
Deduct 0 from 40 and we're left 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.

Let's proceed to step 12:
The number 43 fits into 400 9 times, leaving a remainder of 13.
The next digit of our result is 9. 
Result so far: 19078.837209
Subtract 387 from 400 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Let's proceed to step 13:
43 goes into 130 3 times with a remainder of 1.
Record the quotient 3 as the next digit in the result. 
Result so far: 19078.8372093
Subtracting 129 from 130 leaves us 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.

Going ahead to step 14:
When dividing 10 by 43, we get 0 with a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 19078.8372093
If we take 0 away from 10, we end up with 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 19078.8372093 with a remaining 1e-08.
