Let's divide 22643780 by 578
Our goal is to divide 22643780 by 578.

Moving on to step 1:
If we divide 2 by 578, we get 0 and a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Grab the next digit (2) from the dividend, add it to 2, then carry on: 22 / 578

Going ahead to step 2:
22 divided by 578 is 0 with a remainder of 22.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 22 after subtracting 0 from 22.
Include the next digit (6) from the dividend after 22, then repeat: 226 / 578

Going ahead to step 3:
226 divided by 578 is 0 with a remainder of 226.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 226 leaves us with 226.
Append the next digit (4) from the dividend to 226 and continue with: 2264 / 578

Going ahead to step 4:
578 can be fit into 2264 3 times, resulting in a remainder of 530.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
If we take 1734 away from 2264, we end up with 530.
Bring next digit (3) of the dividend behind the 530 and repeat the process: 5303 / 578

Advancing to step 5:
The number 578 fits into 5303 9 times, leaving a remainder of 101.
Put 9 as the next digit of the answer. 
Result so far: 39.0
If we subtract 5202 from 5303, we get 101.
Include the next digit (7) from the dividend after 101, then repeat: 1017 / 578

On to step 6:
578 can be fit into 1017 1 times, resulting in a remainder of 439.
Write down 1 as next digit of the result. 
Result so far: 391.0
Subtracting 578 from 1017 leaves us with 439.
Take the next digit (8) from the dividend and append it to 439, then repeat: 4398 / 578

Going ahead to step 7:
The number 578 fits into 4398 7 times, leaving a remainder of 352.
Use 7 as the next digit of our solution. 
Result so far: 3917.0
If we take 4046 away from 4398, we end up with 352.
Bring next digit (0) of the dividend behind the 352 and repeat the process: 3520 / 578

Advancing to step 8:
The number 578 fits into 3520 6 times, leaving a remainder of 52.
The next digit of our result is 6. 
Result so far: 39176.0
If we subtract 3468 from 3520, we get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

On to step 9:
578 can be fit into 520 0 times, resulting in a remainder of 520.
The next digit of our result is 0. 
Result so far: 39176.0
If we take 0 away from 520, we end up with 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

Moving on to step 10:
578 can be fit into 5200 8 times, resulting in a remainder of 576.
Put 8 as the next digit of the answer. 
Result so far: 39176.08
Subtracting 4624 from 5200 leaves us with 576.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5760, and continue the process.

Going ahead to step 11:
5760 divided by 578 is 9 with a remainder of 558.
Put 9 as the next digit of the answer. 
Result so far: 39176.089
The remainder is 558 after subtracting 5202 from 5760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5580, and continue the process.

On to step 12:
If we divide 5580 by 578, we get 9 and a remainder of 378.
The number 9 becomes the next digit in our result. 
Result so far: 39176.0899
Subtract 5202 from 5580 to get 378.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3780, and continue the process.

After the division, we end up with 39176.0899 and a remainder of 0.00378.
