31520891 ÷ 581 
Our goal is to divide 31520891 by 581.

Going ahead to step 1:
When dividing 3 by 581, we get 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Take the next digit (1) from the dividend and append it to 3, then repeat: 31 / 581

Let's proceed to step 2:
The number 581 fits into 31 0 times, leaving a remainder of 31.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 31, we get 31.
Grab the next digit (5) from the dividend, add it to 31, then carry on: 315 / 581

Step 3:
315 divided by 581 is 0 with a remainder of 315.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 315, we get 315.
Take the next digit (2) from the dividend and append it to 315, then repeat: 3152 / 581

Advancing to step 4:
If we divide 3152 by 581, we get 5 and a remainder of 247.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
Deduct 2905 from 3152 and we're left with 247.
Bring next digit (0) of the dividend behind the 247 and repeat the process: 2470 / 581

Advancing to step 5:
When dividing 2470 by 581, we get 4 with a remainder of 146.
Put 4 as the next digit of the answer. 
Result so far: 54.0
If we subtract 2324 from 2470, we get 146.
Grab the next digit (8) from the dividend, add it to 146, then carry on: 1468 / 581

Going ahead to step 6:
If we divide 1468 by 581, we get 2 and a remainder of 306.
The next digit of our result is 2. 
Result so far: 542.0
If we take 1162 away from 1468, we end up with 306.
Include the next digit (9) from the dividend after 306, then repeat: 3069 / 581

Step 7:
3069 divided by 581 is 5 with a remainder of 164.
Record the quotient 5 as the next digit in the result. 
Result so far: 5425.0
Subtracting 2905 from 3069 leaves us with 164.
Append the next digit (1) from the dividend to 164 and continue with: 1641 / 581

Advancing to step 8:
581 goes into 1641 2 times with a remainder of 479.
The number 2 becomes the next digit in our result. 
Result so far: 54252.0
If we subtract 1162 from 1641, we get 479.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4790, and continue the process.

On to step 9:
4790 divided by 581 is 8 with a remainder of 142.
The next digit of our result is 8. 
Result so far: 54252.8
Deduct 4648 from 4790 and we're left with 142.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1420, and continue the process.

Let's proceed to step 10:
The number 581 fits into 1420 2 times, leaving a remainder of 258.
Record the quotient 2 as the next digit in the result. 
Result so far: 54252.82
Deduct 1162 from 1420 and we're left with 258.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2580, and continue the process.

On to step 11:
When dividing 2580 by 581, we get 4 with a remainder of 256.
The number 4 becomes the next digit in our result. 
Result so far: 54252.824
Subtracting 2324 from 2580 leaves us with 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

Going ahead to step 12:
When dividing 2560 by 581, we get 4 with a remainder of 236.
Write down 4 as next digit of the result. 
Result so far: 54252.8244
Subtracting 2324 from 2560 leaves us with 236.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2360, and continue the process.

After the division, we end up with 54252.8244 and a remainder of 0.00236.
