12258234 ÷ 564 
Let's see how many times 564 fits into 12258234.

Let's proceed to step 1:
1 divided by 564 is 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 564

Let's proceed to step 2:
When dividing 12 by 564, we get 0 with a remainder of 12.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 12, we get 12.
Take the next digit (2) from the dividend and append it to 12, then repeat: 122 / 564

Advancing to step 3:
If we divide 122 by 564, we get 0 and a remainder of 122.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 122 after subtracting 0 from 122.
Append the next digit (5) from the dividend to 122 and continue with: 1225 / 564

Moving on to step 4:
1225 divided by 564 is 2 with a remainder of 97.
The next digit of our result is 2. 
Result so far: 2.0
The remainder is 97 after subtracting 1128 from 1225.
Append the next digit (8) from the dividend to 97 and continue with: 978 / 564

Step 5:
564 goes into 978 1 times with a remainder of 414.
The number 1 becomes the next digit in our result. 
Result so far: 21.0
Deduct 564 from 978 and we're left with 414.
Fetch the next digit (2) from the dividend, attach it to 414 and continue: 4142 / 564

On to step 6:
The number 564 fits into 4142 7 times, leaving a remainder of 194.
The next digit of our result is 7. 
Result so far: 217.0
Subtracting 3948 from 4142 leaves us with 194.
Grab the next digit (3) from the dividend, add it to 194, then carry on: 1943 / 564

Going ahead to step 7:
The number 564 fits into 1943 3 times, leaving a remainder of 251.
Use 3 as the next digit of our solution. 
Result so far: 2173.0
Deduct 1692 from 1943 and we're left with 251.
Include the next digit (4) from the dividend after 251, then repeat: 2514 / 564

Let's proceed to step 8:
If we divide 2514 by 564, we get 4 and a remainder of 258.
Write down 4 as next digit of the result. 
Result so far: 21734.0
If we take 2256 away from 2514, we end up 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.

Let's proceed to step 9:
564 can be fit into 2580 4 times, resulting in a remainder of 324.
Record the quotient 4 as the next digit in the result. 
Result so far: 21734.4
If we take 2256 away from 2580, we end up with 324.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3240, and continue the process.

Advancing to step 10:
When dividing 3240 by 564, we get 5 with a remainder of 420.
Use 5 as the next digit of our solution. 
Result so far: 21734.45
If we subtract 2820 from 3240, we get 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

Step 11:
If we divide 4200 by 564, we get 7 and a remainder of 252.
Put 7 as the next digit of the answer. 
Result so far: 21734.457
Deduct 3948 from 4200 and we're left with 252.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2520, and continue the process.

Advancing to step 12:
The number 564 fits into 2520 4 times, leaving a remainder of 264.
Use 4 as the next digit of our solution. 
Result so far: 21734.4574
Subtracting 2256 from 2520 leaves us with 264.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2640, and continue the process.

On to step 13:
564 goes into 2640 4 times with a remainder of 384.
Use 4 as the next digit of our solution. 
Result so far: 21734.45744
Subtracting 2256 from 2640 leaves us with 384.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

The quotient of the division is 21734.45744, and the remainder is 0.000384.
