Let's divide 1983448 by 509
We're looking to find how many times 509 goes into 1983448.

Going ahead to step 1:
509 goes into 1 0 times with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Grab the next digit (9) from the dividend, add it to 1, then carry on: 19 / 509

On to step 2:
If we divide 19 by 509, we get 0 and a remainder of 19.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 19 to get 19.
Bring next digit (8) of the dividend behind the 19 and repeat the process: 198 / 509

Step 3:
509 goes into 198 0 times with a remainder of 198.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 198, we end up with 198.
Take the next digit (3) from the dividend and append it to 198, then repeat: 1983 / 509

Going ahead to step 4:
1983 divided by 509 is 3 with a remainder of 456.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Subtracting 1527 from 1983 leaves us with 456.
Fetch the next digit (4) from the dividend, attach it to 456 and continue: 4564 / 509

Moving on to step 5:
If we divide 4564 by 509, we get 8 and a remainder of 492.
The number 8 becomes the next digit in our result. 
Result so far: 38.0
The remainder is 492 after subtracting 4072 from 4564.
Take the next digit (4) from the dividend and append it to 492, then repeat: 4924 / 509

Going ahead to step 6:
When dividing 4924 by 509, we get 9 with a remainder of 343.
Record the quotient 9 as the next digit in the result. 
Result so far: 389.0
Subtracting 4581 from 4924 leaves us with 343.
Fetch the next digit (8) from the dividend, attach it to 343 and continue: 3438 / 509

Moving on to step 7:
3438 divided by 509 is 6 with a remainder of 384.
Write down 6 as next digit of the result. 
Result so far: 3896.0
Subtracting 3054 from 3438 leaves us with 384.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

Let's proceed to step 8:
If we divide 3840 by 509, we get 7 and a remainder of 277.
Use 7 as the next digit of our solution. 
Result so far: 3896.7
Subtracting 3563 from 3840 leaves us with 277.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2770, and continue the process.

Moving on to step 9:
The number 509 fits into 2770 5 times, leaving a remainder of 225.
Use 5 as the next digit of our solution. 
Result so far: 3896.75
If we take 2545 away from 2770, we end up with 225.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2250, and continue the process.

Moving on to step 10:
When dividing 2250 by 509, we get 4 with a remainder of 214.
The number 4 becomes the next digit in our result. 
Result so far: 3896.754
The remainder is 214 after subtracting 2036 from 2250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2140, and continue the process.

Step 11:
When dividing 2140 by 509, we get 4 with a remainder of 104.
Write down 4 as next digit of the result. 
Result so far: 3896.7544
Deduct 2036 from 2140 and we're left with 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Our division results in 3896.7544 with a remaining 0.00104.
