Let's divide 19780809 by 839
Our goal is to divide 19780809 by 839.

Advancing to step 1:
839 can be fit into 1 0 times, resulting in a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Take the next digit (9) from the dividend and append it to 1, then repeat: 19 / 839

Advancing to step 2:
19 divided by 839 is 0 with a remainder of 19.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 19 leaves us with 19.
Fetch the next digit (7) from the dividend, attach it to 19 and continue: 197 / 839

Step 3:
197 divided by 839 is 0 with a remainder of 197.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 197, we get 197.
Bring next digit (8) of the dividend behind the 197 and repeat the process: 1978 / 839

Let's proceed to step 4:
The number 839 fits into 1978 2 times, leaving a remainder of 300.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Deduct 1678 from 1978 and we're left with 300.
Include the next digit (0) from the dividend after 300, then repeat: 3000 / 839

Let's proceed to step 5:
When dividing 3000 by 839, we get 3 with a remainder of 483.
Use 3 as the next digit of our solution. 
Result so far: 23.0
Deduct 2517 from 3000 and we're left with 483.
Append the next digit (8) from the dividend to 483 and continue with: 4838 / 839

Let's proceed to step 6:
839 can be fit into 4838 5 times, resulting in a remainder of 643.
Put 5 as the next digit of the answer. 
Result so far: 235.0
Deduct 4195 from 4838 and we're left with 643.
Bring next digit (0) of the dividend behind the 643 and repeat the process: 6430 / 839

Moving on to step 7:
839 can be fit into 6430 7 times, resulting in a remainder of 557.
Use 7 as the next digit of our solution. 
Result so far: 2357.0
Subtract 5873 from 6430 to get 557.
Fetch the next digit (9) from the dividend, attach it to 557 and continue: 5579 / 839

Moving on to step 8:
839 can be fit into 5579 6 times, resulting in a remainder of 545.
Use 6 as the next digit of our solution. 
Result so far: 23576.0
The remainder is 545 after subtracting 5034 from 5579.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5450, and continue the process.

Let's proceed to step 9:
839 goes into 5450 6 times with a remainder of 416.
Record the quotient 6 as the next digit in the result. 
Result so far: 23576.6
Deduct 5034 from 5450 and we're left with 416.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4160, and continue the process.

Moving on to step 10:
839 can be fit into 4160 4 times, resulting in a remainder of 804.
Write down 4 as next digit of the result. 
Result so far: 23576.64
If we subtract 3356 from 4160, we get 804.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8040, and continue the process.

Going ahead to step 11:
When dividing 8040 by 839, we get 9 with a remainder of 489.
Write down 9 as next digit of the result. 
Result so far: 23576.649
Subtracting 7551 from 8040 leaves us with 489.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4890, and continue the process.

Step 12:
When dividing 4890 by 839, we get 5 with a remainder of 695.
Write down 5 as next digit of the result. 
Result so far: 23576.6495
Deduct 4195 from 4890 and we're left with 695.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6950, and continue the process.

Advancing to step 13:
When dividing 6950 by 839, we get 8 with a remainder of 238.
Use 8 as the next digit of our solution. 
Result so far: 23576.64958
Deduct 6712 from 6950 and we're left with 238.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2380, and continue the process.

Moving on to step 14:
When dividing 2380 by 839, we get 2 with a remainder of 702.
Record the quotient 2 as the next digit in the result. 
Result so far: 23576.649582
The remainder is 702 after subtracting 1678 from 2380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7020, and continue the process.

Going ahead to step 15:
7020 divided by 839 is 8 with a remainder of 308.
Put 8 as the next digit of the answer. 
Result so far: 23576.6495828
If we take 6712 away from 7020, we end up with 308.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3080, and continue the process.

Step 16:
839 goes into 3080 3 times with a remainder of 563.
Use 3 as the next digit of our solution. 
Result so far: 23576.64958283
The remainder is 563 after subtracting 2517 from 3080.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5630, and continue the process.

Our division results in 23576.64958283 with a remaining 5.63e-07.
