Let's divide 23139569 by 561
We're looking to find how many times 561 goes into 23139569.

Let's proceed to step 1:
When dividing 2 by 561, we get 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Take the next digit (3) from the dividend and append it to 2, then repeat: 23 / 561

Advancing to step 2:
561 goes into 23 0 times with a remainder of 23.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 23 to get 23.
Fetch the next digit (1) from the dividend, attach it to 23 and continue: 231 / 561

On to step 3:
561 goes into 231 0 times with a remainder of 231.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 231 after subtracting 0 from 231.
Bring next digit (3) of the dividend behind the 231 and repeat the process: 2313 / 561

On to step 4:
561 can be fit into 2313 4 times, resulting in a remainder of 69.
The next digit of our result is 4. 
Result so far: 4.0
Subtract 2244 from 2313 to get 69.
Append the next digit (9) from the dividend to 69 and continue with: 699 / 561

Moving on to step 5:
561 goes into 699 1 times with a remainder of 138.
Record the quotient 1 as the next digit in the result. 
Result so far: 41.0
The remainder is 138 after subtracting 561 from 699.
Bring next digit (5) of the dividend behind the 138 and repeat the process: 1385 / 561

On to step 6:
561 goes into 1385 2 times with a remainder of 263.
Write down 2 as next digit of the result. 
Result so far: 412.0
If we take 1122 away from 1385, we end up with 263.
Bring next digit (6) of the dividend behind the 263 and repeat the process: 2636 / 561

Going ahead to step 7:
2636 divided by 561 is 4 with a remainder of 392.
Record the quotient 4 as the next digit in the result. 
Result so far: 4124.0
If we subtract 2244 from 2636, we get 392.
Append the next digit (9) from the dividend to 392 and continue with: 3929 / 561

Advancing to step 8:
561 can be fit into 3929 7 times, resulting in a remainder of 2.
Write down 7 as next digit of the result. 
Result so far: 41247.0
The remainder is 2 after subtracting 3927 from 3929.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 9:
When dividing 20 by 561, we get 0 with a remainder of 20.
The next digit of our result is 0. 
Result so far: 41247.0
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 10:
The number 561 fits into 200 0 times, leaving a remainder of 200.
Record the quotient 0 as the next digit in the result. 
Result so far: 41247.0
If we subtract 0 from 200, we get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

After the division, we end up with 41247.0 and a remainder of 0.2.
