We look at the division of 820345 by 43 
We want to figure out the number of times 820345 can be divided by 43.

Step 1:
When dividing 8 by 43, we get 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Take the next digit (2) from the dividend and append it to 8, then repeat: 82 / 43

Going ahead to step 2:
When dividing 82 by 43, we get 1 with a remainder of 39.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 43 from 82, we get 39.
Bring next digit (0) of the dividend behind the 39 and repeat the process: 390 / 43

Advancing 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
Subtract 387 from 390 to get 3.
Take the next digit (3) from the dividend and append it to 3, then repeat: 33 / 43

Let's proceed to step 4:
33 divided by 43 is 0 with a remainder of 33.
Write down 0 as next digit of the result. 
Result so far: 190.0
Deduct 0 from 33 and we're left with 33.
Bring next digit (4) of the dividend behind the 33 and repeat the process: 334 / 43

Moving on to step 5:
The number 43 fits into 334 7 times, leaving a remainder of 33.
The next digit of our result is 7. 
Result so far: 1907.0
The remainder is 33 after subtracting 301 from 334.
Include the next digit (5) from the dividend after 33, then repeat: 335 / 43

On to step 6:
43 goes into 335 7 times with a remainder of 34.
Write down 7 as next digit of the result. 
Result so far: 19077.0
If we take 301 away from 335, we end up with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

On to step 7:
The number 43 fits into 340 7 times, leaving a remainder of 39.
The number 7 becomes the next digit in our result. 
Result so far: 19077.7
Deduct 301 from 340 and we're left with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Advancing to step 8:
If we divide 390 by 43, we get 9 and a remainder of 3.
Record the quotient 9 as the next digit in the result. 
Result so far: 19077.79
If we subtract 387 from 390, we 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.

Going ahead to step 9:
43 can be fit into 30 0 times, resulting in a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 19077.79
The remainder is 30 after subtracting 0 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 10:
If we divide 300 by 43, we get 6 and a remainder of 42.
Record the quotient 6 as the next digit in the result. 
Result so far: 19077.7906
If we take 258 away from 300, we end up with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

On to step 11:
The number 43 fits into 420 9 times, leaving a remainder of 33.
Record the quotient 9 as the next digit in the result. 
Result so far: 19077.79069
If we take 387 away from 420, we end up 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.

On to step 12:
43 can be fit into 330 7 times, resulting in a remainder of 29.
Use 7 as the next digit of our solution. 
Result so far: 19077.790697
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.

On to step 13:
43 can be fit into 290 6 times, resulting in a remainder of 32.
Record the quotient 6 as the next digit in the result. 
Result so far: 19077.7906976
If we take 258 away from 290, we end up 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 14:
43 can be fit into 320 7 times, resulting in a remainder of 19.
The next digit of our result is 7. 
Result so far: 19077.79069767
The remainder is 19 after subtracting 301 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

After the division, we end up with 19077.79069767 and a remainder of 1.9e-08.
