We're dividing 83543968 by 409 
We're looking to find how many times 409 goes into 83543968.

Advancing to step 1:
When dividing 8 by 409, we get 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Append the next digit (3) from the dividend to 8 and continue with: 83 / 409

Going ahead to step 2:
409 goes into 83 0 times with a remainder of 83.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 83 leaves us with 83.
Include the next digit (5) from the dividend after 83, then repeat: 835 / 409

Step 3:
409 goes into 835 2 times with a remainder of 17.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we take 818 away from 835, we end up with 17.
Take the next digit (4) from the dividend and append it to 17, then repeat: 174 / 409

Advancing to step 4:
409 goes into 174 0 times with a remainder of 174.
Write down 0 as next digit of the result. 
Result so far: 20.0
Deduct 0 from 174 and we're left with 174.
Include the next digit (3) from the dividend after 174, then repeat: 1743 / 409

Moving on to step 5:
When dividing 1743 by 409, we get 4 with a remainder of 107.
The number 4 becomes the next digit in our result. 
Result so far: 204.0
The remainder is 107 after subtracting 1636 from 1743.
Include the next digit (9) from the dividend after 107, then repeat: 1079 / 409

Let's proceed to step 6:
The number 409 fits into 1079 2 times, leaving a remainder of 261.
Use 2 as the next digit of our solution. 
Result so far: 2042.0
Subtracting 818 from 1079 leaves us with 261.
Include the next digit (6) from the dividend after 261, then repeat: 2616 / 409

On to step 7:
If we divide 2616 by 409, we get 6 and a remainder of 162.
Use 6 as the next digit of our solution. 
Result so far: 20426.0
The remainder is 162 after subtracting 2454 from 2616.
Bring next digit (8) of the dividend behind the 162 and repeat the process: 1628 / 409

Going ahead to step 8:
When dividing 1628 by 409, we get 3 with a remainder of 401.
The next digit of our result is 3. 
Result so far: 204263.0
If we subtract 1227 from 1628, we get 401.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4010, and continue the process.

Let's proceed to step 9:
The number 409 fits into 4010 9 times, leaving a remainder of 329.
Put 9 as the next digit of the answer. 
Result so far: 204263.9
Deduct 3681 from 4010 and we're left with 329.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3290, and continue the process.

Step 10:
If we divide 3290 by 409, we get 8 and a remainder of 18.
The next digit of our result is 8. 
Result so far: 204263.98
If we take 3272 away from 3290, 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.

Step 11:
180 divided by 409 is 0 with a remainder of 180.
The next digit of our result is 0. 
Result so far: 204263.98
Deduct 0 from 180 and we're left with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Step 12:
409 goes into 1800 4 times with a remainder of 164.
Record the quotient 4 as the next digit in the result. 
Result so far: 204263.9804
Subtract 1636 from 1800 to get 164.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

On to step 13:
1640 divided by 409 is 4 with a remainder of 4.
Write down 4 as next digit of the result. 
Result so far: 204263.98044
Subtracting 1636 from 1640 leaves us 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.

In conclusion, the division gives 204263.98044 with a balance of 4e-06.
