8229488 divided by 391 
Our goal is to divide 8229488 by 391.

Advancing to step 1:
When dividing 8 by 391, we get 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Fetch the next digit (2) from the dividend, attach it to 8 and continue: 82 / 391

Moving on to step 2:
The number 391 fits into 82 0 times, leaving a remainder of 82.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 82 leaves us with 82.
Fetch the next digit (2) from the dividend, attach it to 82 and continue: 822 / 391

Step 3:
391 goes into 822 2 times with a remainder of 40.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we take 782 away from 822, we end up with 40.
Grab the next digit (9) from the dividend, add it to 40, then carry on: 409 / 391

Step 4:
409 divided by 391 is 1 with a remainder of 18.
Put 1 as the next digit of the answer. 
Result so far: 21.0
If we take 391 away from 409, we end up with 18.
Grab the next digit (4) from the dividend, add it to 18, then carry on: 184 / 391

Going ahead to step 5:
If we divide 184 by 391, we get 0 and a remainder of 184.
The next digit of our result is 0. 
Result so far: 210.0
If we take 0 away from 184, we end up with 184.
Bring next digit (8) of the dividend behind the 184 and repeat the process: 1848 / 391

Advancing to step 6:
391 can be fit into 1848 4 times, resulting in a remainder of 284.
The number 4 becomes the next digit in our result. 
Result so far: 2104.0
Subtract 1564 from 1848 to get 284.
Include the next digit (8) from the dividend after 284, then repeat: 2848 / 391

On to step 7:
The number 391 fits into 2848 7 times, leaving a remainder of 111.
Use 7 as the next digit of our solution. 
Result so far: 21047.0
Subtract 2737 from 2848 to get 111.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1110, and continue the process.

Advancing to step 8:
1110 divided by 391 is 2 with a remainder of 328.
Put 2 as the next digit of the answer. 
Result so far: 21047.2
The remainder is 328 after subtracting 782 from 1110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3280, and continue the process.

Moving on to step 9:
391 goes into 3280 8 times with a remainder of 152.
The next digit of our result is 8. 
Result so far: 21047.28
If we take 3128 away from 3280, we end up with 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

Let's proceed to step 10:
391 goes into 1520 3 times with a remainder of 347.
The next digit of our result is 3. 
Result so far: 21047.283
The remainder is 347 after subtracting 1173 from 1520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3470, and continue the process.

On to step 11:
391 can be fit into 3470 8 times, resulting in a remainder of 342.
The next digit of our result is 8. 
Result so far: 21047.2838
If we subtract 3128 from 3470, we get 342.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3420, and continue the process.

Step 12:
If we divide 3420 by 391, we get 8 and a remainder of 292.
The next digit of our result is 8. 
Result so far: 21047.28388
If we subtract 3128 from 3420, we get 292.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2920, and continue the process.

After the division, we end up with 21047.28388 and a remainder of 0.000292.
