581 can be fit into 3797 6 times, resulting in a remainder of 311.
Write down 6 as next digit of the result. 
Result so far: 146.0
Subtracting 3486 from 3797 leaves us with 311.
Take the next digit (3) from the dividend and append it to 311, then repeat: 3113 / 581

Step 6:
If we divide 3113 by 581, we get 5 and a remainder of 208.
The next digit of our result is 5. 
Result so far: 1465.0
Subtract 2905 from 3113 to get 208.
Grab the next digit (5) from the dividend, add it to 208, then carry on: 2085 / 581

Let's proceed to step 7:
581 can be fit into 2085 3 times, resulting in a remainder of 342.
Write down 3 as next digit of the result. 
Result so far: 14653.0
The remainder is 342 after subtracting 1743 from 2085.
Grab the next digit (4) from the dividend, add it to 342, then carry on: 3424 / 581

On to step 8:
3424 divided by 581 is 5 with a remainder of 519.
Record the quotient 5 as the next digit in the result. 
Result so far: 146535.0
Subtracting 2905 from 3424 leaves us with 519.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5190, and continue the process.

On to step 9:
5190 divided by 581 is 8 with a remainder of 542.
The next digit of our result is 8. 
Result so far: 146535.8
Subtract 4648 from 5190 to get 542.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5420, and continue the process.

Moving on to step 10:
5420 divided by 581 is 9 with a remainder of 191.
Use 9 as the next digit of our solution. 
Result so far: 146535.89
If we subtract 5229 from 5420, we get 191.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1910, and continue the process.

Moving on to step 11:
1910 divided by 581 is 3 with a remainder of 167.
Use 3 as the next digit of our solution. 
Result so far: 146535.893
The remainder is 167 after subtracting 1743 from 1910.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1670, and continue the process.

Going ahead to step 12:
When dividing 1670 by 581, we get 2 with a remainder of 508.
Record the quotient 2 as the next digit in the result. 
Result so far: 146535.8932
The remainder is 508 after subtracting 1162 from 1670.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5080, and continue the process.

Let's proceed to step 13:
When dividing 5080 by 581, we get 8 with a remainder of 432.
Put 8 as the next digit of the answer. 
Result so far: 146535.89328
Subtracting 4648 from 5080 leaves us with 432.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4320, and continue the process.

Step 14:
581 can be fit into 4320 7 times, resulting in a remainder of 253.
The number 7 becomes the next digit in our result. 
Result so far: 146535.893287
If we take 4067 away from 4320, we end up with 253.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2530, and continue the process.

Step 15:
When dividing 2530 by 581, we get 4 with a remainder of 206.
The next digit of our result is 4. 
Result so far: 146535.8932874
Subtracting 2324 from 2530 leaves us with 206.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2060, and continue the process.

Moving on to step 16:
If we divide 2060 by 581, we get 3 and a remainder of 317.
Use 3 as the next digit of our solution. 
Result so far: 146535.89328743
If we take 1743 away from 2060, we end up with 317.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3170, and continue the process.

The final result is 146535.89328743 with a remainder of 3.17e-07.
