We're dividing 12122319 by 581 
We want to divide 12122319 by 581.

Going ahead to step 1:
When dividing 1 by 581, we get 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 581

Step 2:
If we divide 12 by 581, we get 0 and a remainder of 12.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 12 to get 12.
Grab the next digit (1) from the dividend, add it to 12, then carry on: 121 / 581

Advancing to step 3:
581 goes into 121 0 times with a remainder of 121.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 121 to get 121.
Append the next digit (2) from the dividend to 121 and continue with: 1212 / 581

On to step 4:
When dividing 1212 by 581, we get 2 with a remainder of 50.
The next digit of our result is 2. 
Result so far: 2.0
If we subtract 1162 from 1212, we get 50.
Bring next digit (2) of the dividend behind the 50 and repeat the process: 502 / 581

Moving on to step 5:
502 divided by 581 is 0 with a remainder of 502.
Use 0 as the next digit of our solution. 
Result so far: 20.0
If we take 0 away from 502, we end up with 502.
Take the next digit (3) from the dividend and append it to 502, then repeat: 5023 / 581

Moving on to step 6:
When dividing 5023 by 581, we get 8 with a remainder of 375.
Put 8 as the next digit of the answer. 
Result so far: 208.0
Deduct 4648 from 5023 and we're left with 375.
Bring next digit (1) of the dividend behind the 375 and repeat the process: 3751 / 581

Going ahead to step 7:
3751 divided by 581 is 6 with a remainder of 265.
Record the quotient 6 as the next digit in the result. 
Result so far: 2086.0
Subtract 3486 from 3751 to get 265.
Take the next digit (9) from the dividend and append it to 265, then repeat: 2659 / 581

Moving on to step 8:
The number 581 fits into 2659 4 times, leaving a remainder of 335.
Record the quotient 4 as the next digit in the result. 
Result so far: 20864.0
Deduct 2324 from 2659 and we're left with 335.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3350, and continue the process.

Advancing to step 9:
3350 divided by 581 is 5 with a remainder of 445.
Write down 5 as next digit of the result. 
Result so far: 20864.5
If we take 2905 away from 3350, we end up with 445.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4450, and continue the process.

Step 10:
When dividing 4450 by 581, we get 7 with a remainder of 383.
The number 7 becomes the next digit in our result. 
Result so far: 20864.57
Subtract 4067 from 4450 to get 383.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3830, and continue the process.

Moving on to step 11:
When dividing 3830 by 581, we get 6 with a remainder of 344.
The next digit of our result is 6. 
Result so far: 20864.576
Subtracting 3486 from 3830 leaves us with 344.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3440, and continue the process.

Advancing to step 12:
The number 581 fits into 3440 5 times, leaving a remainder of 535.
Record the quotient 5 as the next digit in the result. 
Result so far: 20864.5765
The remainder is 535 after subtracting 2905 from 3440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5350, and continue the process.

Going ahead to step 13:
581 can be fit into 5350 9 times, resulting in a remainder of 121.
Put 9 as the next digit of the answer. 
Result so far: 20864.57659
If we subtract 5229 from 5350, we get 121.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1210, and continue the process.

Step 14:
If we divide 1210 by 581, we get 2 and a remainder of 48.
Record the quotient 2 as the next digit in the result. 
Result so far: 20864.576592
Subtract 1162 from 1210 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Step 15:
The number 581 fits into 480 0 times, leaving a remainder of 480.
Record the quotient 0 as the next digit in the result. 
Result so far: 20864.576592
If we subtract 0 from 480, we get 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Advancing to step 16:
4800 divided by 581 is 8 with a remainder of 152.
Write down 8 as next digit of the result. 
Result so far: 20864.57659208
Subtract 4648 from 4800 to get 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

Our division results in 20864.57659208 with a remaining 1.52e-07.
