We divide 31321621 by 863
We want to figure out the number of times 31321621 can be divided by 863.

On to step 1:
3 divided by 863 is 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Take the next digit (1) from the dividend and append it to 3, then repeat: 31 / 863

Step 2:
When dividing 31 by 863, we get 0 with a remainder of 31.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 31 after subtracting 0 from 31.
Append the next digit (3) from the dividend to 31 and continue with: 313 / 863

Advancing to step 3:
863 goes into 313 0 times with a remainder of 313.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 313 leaves us with 313.
Take the next digit (2) from the dividend and append it to 313, then repeat: 3132 / 863

Going ahead to step 4:
863 can be fit into 3132 3 times, resulting in a remainder of 543.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we take 2589 away from 3132, we end up with 543.
Fetch the next digit (1) from the dividend, attach it to 543 and continue: 5431 / 863

Moving on to step 5:
If we divide 5431 by 863, we get 6 and a remainder of 253.
Use 6 as the next digit of our solution. 
Result so far: 36.0
The remainder is 253 after subtracting 5178 from 5431.
Append the next digit (6) from the dividend to 253 and continue with: 2536 / 863

Step 6:
When dividing 2536 by 863, we get 2 with a remainder of 810.
Record the quotient 2 as the next digit in the result. 
Result so far: 362.0
Deduct 1726 from 2536 and we're left with 810.
Fetch the next digit (2) from the dividend, attach it to 810 and continue: 8102 / 863

On to step 7:
8102 divided by 863 is 9 with a remainder of 335.
Put 9 as the next digit of the answer. 
Result so far: 3629.0
If we take 7767 away from 8102, we end up with 335.
Fetch the next digit (1) from the dividend, attach it to 335 and continue: 3351 / 863

Step 8:
If we divide 3351 by 863, we get 3 and a remainder of 762.
Use 3 as the next digit of our solution. 
Result so far: 36293.0
The remainder is 762 after subtracting 2589 from 3351.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7620, and continue the process.

Let's proceed to step 9:
When dividing 7620 by 863, we get 8 with a remainder of 716.
Use 8 as the next digit of our solution. 
Result so far: 36293.8
If we subtract 6904 from 7620, we get 716.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7160, and continue the process.

Step 10:
7160 divided by 863 is 8 with a remainder of 256.
Use 8 as the next digit of our solution. 
Result so far: 36293.88
Subtract 6904 from 7160 to get 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

In conclusion, the division gives 36293.88 with a balance of 0.256.
