We look at the division of 31921815 by 581 
Our goal is to divide 31921815 by 581.

On to step 1:
581 can be fit into 3 0 times, resulting in 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.
Grab the next digit (1) from the dividend, add it to 3, then carry on: 31 / 581

Let's proceed to step 2:
The number 581 fits into 31 0 times, leaving a remainder of 31.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 31 to get 31.
Take the next digit (9) from the dividend and append it to 31, then repeat: 319 / 581

Going ahead to step 3:
The number 581 fits into 319 0 times, leaving a remainder of 319.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 319 to get 319.
Grab the next digit (2) from the dividend, add it to 319, then carry on: 3192 / 581

On to step 4:
581 can be fit into 3192 5 times, resulting in a remainder of 287.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
Subtracting 2905 from 3192 leaves us with 287.
Append the next digit (1) from the dividend to 287 and continue with: 2871 / 581

Step 5:
581 can be fit into 2871 4 times, resulting in a remainder of 547.
Put 4 as the next digit of the answer. 
Result so far: 54.0
If we take 2324 away from 2871, we end up with 547.
Append the next digit (8) from the dividend to 547 and continue with: 5478 / 581

Let's proceed to step 6:
The number 581 fits into 5478 9 times, leaving a remainder of 249.
The number 9 becomes the next digit in our result. 
Result so far: 549.0
If we take 5229 away from 5478, we end up with 249.
Append the next digit (1) from the dividend to 249 and continue with: 2491 / 581

Let's proceed to step 7:
581 goes into 2491 4 times with a remainder of 167.
The next digit of our result is 4. 
Result so far: 5494.0
Subtract 2324 from 2491 to get 167.
Append the next digit (5) from the dividend to 167 and continue with: 1675 / 581

Advancing to step 8:
When dividing 1675 by 581, we get 2 with a remainder of 513.
Record the quotient 2 as the next digit in the result. 
Result so far: 54942.0
Deduct 1162 from 1675 and we're left with 513.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5130, and continue the process.

Advancing to step 9:
When dividing 5130 by 581, we get 8 with a remainder of 482.
Write down 8 as next digit of the result. 
Result so far: 54942.8
If we take 4648 away from 5130, we end up with 482.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4820, and continue the process.

Moving on to step 10:
581 goes into 4820 8 times with a remainder of 172.
Write down 8 as next digit of the result. 
Result so far: 54942.88
If we subtract 4648 from 4820, we get 172.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

The final outcome is 54942.88, with a leftover of 0.172.
