We're dividing 3080404 by 839 
We want to divide 3080404 by 839.

Step 1:
When dividing 3 by 839, we get 0 with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Take the next digit (0) from the dividend and append it to 3, then repeat: 30 / 839

Let's proceed to step 2:
839 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: 0.0
Subtracting 0 from 30 leaves us with 30.
Bring next digit (8) of the dividend behind the 30 and repeat the process: 308 / 839

Moving on to step 3:
308 divided by 839 is 0 with a remainder of 308.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 308 to get 308.
Include the next digit (0) from the dividend after 308, then repeat: 3080 / 839

Going ahead to step 4:
When dividing 3080 by 839, we get 3 with a remainder of 563.
Use 3 as the next digit of our solution. 
Result so far: 3.0
The remainder is 563 after subtracting 2517 from 3080.
Include the next digit (4) from the dividend after 563, then repeat: 5634 / 839

Moving on to step 5:
The number 839 fits into 5634 6 times, leaving a remainder of 600.
Record the quotient 6 as the next digit in the result. 
Result so far: 36.0
Deduct 5034 from 5634 and we're left with 600.
Append the next digit (0) from the dividend to 600 and continue with: 6000 / 839

Step 6:
6000 divided by 839 is 7 with a remainder of 127.
The number 7 becomes the next digit in our result. 
Result so far: 367.0
Subtracting 5873 from 6000 leaves us with 127.
Take the next digit (4) from the dividend and append it to 127, then repeat: 1274 / 839

On to step 7:
The number 839 fits into 1274 1 times, leaving a remainder of 435.
The number 1 becomes the next digit in our result. 
Result so far: 3671.0
If we subtract 839 from 1274, we get 435.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4350, and continue the process.

Let's proceed to step 8:
If we divide 4350 by 839, we get 5 and a remainder of 155.
The number 5 becomes the next digit in our result. 
Result so far: 3671.5
If we subtract 4195 from 4350, we get 155.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1550, and continue the process.

Going ahead to step 9:
When dividing 1550 by 839, we get 1 with a remainder of 711.
Put 1 as the next digit of the answer. 
Result so far: 3671.51
The remainder is 711 after subtracting 839 from 1550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7110, and continue the process.

Advancing to step 10:
The number 839 fits into 7110 8 times, leaving a remainder of 398.
Write down 8 as next digit of the result. 
Result so far: 3671.518
If we take 6712 away from 7110, we end up with 398.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3980, and continue the process.

Let's proceed to step 11:
839 goes into 3980 4 times with a remainder of 624.
The next digit of our result is 4. 
Result so far: 3671.5184
If we take 3356 away from 3980, we end up with 624.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6240, and continue the process.

Going ahead to step 12:
839 can be fit into 6240 7 times, resulting in a remainder of 367.
Record the quotient 7 as the next digit in the result. 
Result so far: 3671.51847
The remainder is 367 after subtracting 5873 from 6240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3670, and continue the process.

Going ahead to step 13:
The number 839 fits into 3670 4 times, leaving a remainder of 314.
Use 4 as the next digit of our solution. 
Result so far: 3671.518474
If we take 3356 away from 3670, we end up with 314.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3140, and continue the process.

Let's proceed to step 14:
3140 divided by 839 is 3 with a remainder of 623.
Use 3 as the next digit of our solution. 
Result so far: 3671.5184743
Subtracting 2517 from 3140 leaves us with 623.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6230, and continue the process.

Step 15:
The number 839 fits into 6230 7 times, leaving a remainder of 357.
Write down 7 as next digit of the result. 
Result so far: 3671.51847437
If we subtract 5873 from 6230, we get 357.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3570, and continue the process.

The final outcome is 3671.51847437, with a leftover of 3.57e-07.
