We look at the division of 839660 by 43 
We want to figure out the number of times 839660 can be divided by 43.

Let's proceed to step 1:
43 can be fit into 8 0 times, resulting in a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Bring next digit (3) of the dividend behind the 8 and repeat the process: 83 / 43

Advancing to step 2:
The number 43 fits into 83 1 times, leaving a remainder of 40.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 43 from 83 and we're left with 40.
Take the next digit (9) from the dividend and append it to 40, then repeat: 409 / 43

On to step 3:
The number 43 fits into 409 9 times, leaving a remainder of 22.
Use 9 as the next digit of our solution. 
Result so far: 19.0
Subtract 387 from 409 to get 22.
Grab the next digit (6) from the dividend, add it to 22, then carry on: 226 / 43

On to step 4:
If we divide 226 by 43, we get 5 and a remainder of 11.
The number 5 becomes the next digit in our result. 
Result so far: 195.0
The remainder is 11 after subtracting 215 from 226.
Fetch the next digit (6) from the dividend, attach it to 11 and continue: 116 / 43

Advancing to step 5:
If we divide 116 by 43, we get 2 and a remainder of 30.
Write down 2 as next digit of the result. 
Result so far: 1952.0
Subtract 86 from 116 to get 30.
Append the next digit (0) from the dividend to 30 and continue with: 300 / 43

Let's proceed to step 6:
If we divide 300 by 43, we get 6 and a remainder of 42.
The number 6 becomes the next digit in our result. 
Result so far: 19526.0
Deduct 258 from 300 and we're left 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.

Advancing to step 7:
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: 19526.9
Subtracting 387 from 420 leaves us 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.

Going ahead to step 8:
When dividing 330 by 43, we get 7 with a remainder of 29.
Use 7 as the next digit of our solution. 
Result so far: 19526.97
Deduct 301 from 330 and we're left 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.

Let's proceed to step 9:
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: 19526.976
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.

Going ahead to step 10:
43 goes into 320 7 times with a remainder of 19.
Write down 7 as next digit of the result. 
Result so far: 19526.9767
Subtracting 301 from 320 leaves us 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.

Moving on to step 11:
190 divided by 43 is 4 with a remainder of 18.
The number 4 becomes the next digit in our result. 
Result so far: 19526.97674
Subtracting 172 from 190 leaves us 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.

On to step 12:
If we divide 180 by 43, we get 4 and a remainder of 8.
Write down 4 as next digit of the result. 
Result so far: 19526.976744
If we take 172 away from 180, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The final result is 19526.976744 with a remainder of 8e-07.
