We divide 3115259 by 821
We want to divide 3115259 by 821.

Step 1:
When dividing 3 by 821, we get 0 with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Grab the next digit (1) from the dividend, add it to 3, then carry on: 31 / 821

Let's proceed to step 2:
If we divide 31 by 821, we get 0 and a remainder of 31.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 31, we get 31.
Take the next digit (1) from the dividend and append it to 31, then repeat: 311 / 821

Let's proceed to step 3:
821 goes into 311 0 times with a remainder of 311.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 311 after subtracting 0 from 311.
Take the next digit (5) from the dividend and append it to 311, then repeat: 3115 / 821

Advancing to step 4:
When dividing 3115 by 821, we get 3 with a remainder of 652.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we take 2463 away from 3115, we end up with 652.
Take the next digit (2) from the dividend and append it to 652, then repeat: 6522 / 821

Moving on to step 5:
821 goes into 6522 7 times with a remainder of 775.
The next digit of our result is 7. 
Result so far: 37.0
If we take 5747 away from 6522, we end up with 775.
Append the next digit (5) from the dividend to 775 and continue with: 7755 / 821

Step 6:
When dividing 7755 by 821, we get 9 with a remainder of 366.
The next digit of our result is 9. 
Result so far: 379.0
Deduct 7389 from 7755 and we're left with 366.
Take the next digit (9) from the dividend and append it to 366, then repeat: 3669 / 821

On to step 7:
When dividing 3669 by 821, we get 4 with a remainder of 385.
The number 4 becomes the next digit in our result. 
Result so far: 3794.0
Subtracting 3284 from 3669 leaves us with 385.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3850, and continue the process.

Let's proceed to step 8:
3850 divided by 821 is 4 with a remainder of 566.
Use 4 as the next digit of our solution. 
Result so far: 3794.4
Deduct 3284 from 3850 and we're left with 566.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5660, and continue the process.

Advancing to step 9:
The number 821 fits into 5660 6 times, leaving a remainder of 734.
Write down 6 as next digit of the result. 
Result so far: 3794.46
Subtracting 4926 from 5660 leaves us with 734.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7340, and continue the process.

Moving on to step 10:
821 goes into 7340 8 times with a remainder of 772.
Write down 8 as next digit of the result. 
Result so far: 3794.468
If we subtract 6568 from 7340, we get 772.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7720, and continue the process.

Going ahead to step 11:
If we divide 7720 by 821, we get 9 and a remainder of 331.
Put 9 as the next digit of the answer. 
Result so far: 3794.4689
Deduct 7389 from 7720 and we're left with 331.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3310, and continue the process.

Going ahead to step 12:
3310 divided by 821 is 4 with a remainder of 26.
Write down 4 as next digit of the result. 
Result so far: 3794.46894
Subtracting 3284 from 3310 leaves us with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Step 13:
If we divide 260 by 821, we get 0 and a remainder of 260.
Use 0 as the next digit of our solution. 
Result so far: 3794.46894
Subtracting 0 from 260 leaves us with 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Advancing to step 14:
821 goes into 2600 3 times with a remainder of 137.
Write down 3 as next digit of the result. 
Result so far: 3794.4689403
The remainder is 137 after subtracting 2463 from 2600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1370, and continue the process.

Let's proceed to step 15:
The number 821 fits into 1370 1 times, leaving a remainder of 549.
Use 1 as the next digit of our solution. 
Result so far: 3794.46894031
The remainder is 549 after subtracting 821 from 1370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5490, and continue the process.

Our division results in 3794.46894031 with a remaining 5.49e-07.
