Let's divide 3091823 by 439
We want to divide 3091823 by 439.

On to step 1:
The number 439 fits into 3 0 times, leaving a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Fetch the next digit (0) from the dividend, attach it to 3 and continue: 30 / 439

Moving on to step 2:
When dividing 30 by 439, we get 0 with 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.
Include the next digit (9) from the dividend after 30, then repeat: 309 / 439

Going ahead to step 3:
439 goes into 309 0 times with a remainder of 309.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 309 after subtracting 0 from 309.
Bring next digit (1) of the dividend behind the 309 and repeat the process: 3091 / 439

Step 4:
If we divide 3091 by 439, we get 7 and a remainder of 18.
The next digit of our result is 7. 
Result so far: 7.0
The remainder is 18 after subtracting 3073 from 3091.
Take the next digit (8) from the dividend and append it to 18, then repeat: 188 / 439

Moving on to step 5:
If we divide 188 by 439, we get 0 and a remainder of 188.
The next digit of our result is 0. 
Result so far: 70.0
The remainder is 188 after subtracting 0 from 188.
Take the next digit (2) from the dividend and append it to 188, then repeat: 1882 / 439

Going ahead to step 6:
1882 divided by 439 is 4 with a remainder of 126.
Write down 4 as next digit of the result. 
Result so far: 704.0
If we subtract 1756 from 1882, we get 126.
Bring next digit (3) of the dividend behind the 126 and repeat the process: 1263 / 439

On to step 7:
1263 divided by 439 is 2 with a remainder of 385.
Record the quotient 2 as the next digit in the result. 
Result so far: 7042.0
If we subtract 878 from 1263, we get 385.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3850, and continue the process.

On to step 8:
If we divide 3850 by 439, we get 8 and a remainder of 338.
Record the quotient 8 as the next digit in the result. 
Result so far: 7042.8
If we take 3512 away from 3850, we end up with 338.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3380, and continue the process.

Step 9:
When dividing 3380 by 439, we get 7 with a remainder of 307.
Use 7 as the next digit of our solution. 
Result so far: 7042.87
The remainder is 307 after subtracting 3073 from 3380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3070, and continue the process.

On to step 10:
The number 439 fits into 3070 6 times, leaving a remainder of 436.
Put 6 as the next digit of the answer. 
Result so far: 7042.876
The remainder is 436 after subtracting 2634 from 3070.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4360, and continue the process.

On to step 11:
The number 439 fits into 4360 9 times, leaving a remainder of 409.
The next digit of our result is 9. 
Result so far: 7042.8769
If we subtract 3951 from 4360, we get 409.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4090, and continue the process.

Advancing to step 12:
If we divide 4090 by 439, we get 9 and a remainder of 139.
The number 9 becomes the next digit in our result. 
Result so far: 7042.87699
If we take 3951 away from 4090, we end up with 139.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1390, and continue the process.

Our division results in 7042.87699 with a remaining 0.000139.
