We're dividing 25453059 by 561 
We want to figure out the number of times 25453059 can be divided by 561.

On to step 1:
If we divide 2 by 561, we get 0 and a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Append the next digit (5) from the dividend to 2 and continue with: 25 / 561

On to step 2:
If we divide 25 by 561, we get 0 and a remainder of 25.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 25, we get 25.
Fetch the next digit (4) from the dividend, attach it to 25 and continue: 254 / 561

Let's proceed to step 3:
When dividing 254 by 561, we get 0 with a remainder of 254.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 254 and we're left with 254.
Take the next digit (5) from the dividend and append it to 254, then repeat: 2545 / 561

Advancing to step 4:
561 can be fit into 2545 4 times, resulting in a remainder of 301.
Use 4 as the next digit of our solution. 
Result so far: 4.0
The remainder is 301 after subtracting 2244 from 2545.
Append the next digit (3) from the dividend to 301 and continue with: 3013 / 561

On to step 5:
The number 561 fits into 3013 5 times, leaving a remainder of 208.
The next digit of our result is 5. 
Result so far: 45.0
Subtract 2805 from 3013 to get 208.
Take the next digit (0) from the dividend and append it to 208, then repeat: 2080 / 561

Moving on to step 6:
The number 561 fits into 2080 3 times, leaving a remainder of 397.
The next digit of our result is 3. 
Result so far: 453.0
Subtracting 1683 from 2080 leaves us with 397.
Bring next digit (5) of the dividend behind the 397 and repeat the process: 3975 / 561

Moving on to step 7:
The number 561 fits into 3975 7 times, leaving a remainder of 48.
Record the quotient 7 as the next digit in the result. 
Result so far: 4537.0
If we take 3927 away from 3975, we end up with 48.
Bring next digit (9) of the dividend behind the 48 and repeat the process: 489 / 561

Moving on to step 8:
The number 561 fits into 489 0 times, leaving a remainder of 489.
The next digit of our result is 0. 
Result so far: 45370.0
If we subtract 0 from 489, we get 489.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4890, and continue the process.

On to step 9:
When dividing 4890 by 561, we get 8 with a remainder of 402.
Write down 8 as next digit of the result. 
Result so far: 45370.8
Deduct 4488 from 4890 and we're left with 402.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4020, and continue the process.

Moving on to step 10:
The number 561 fits into 4020 7 times, leaving a remainder of 93.
The number 7 becomes the next digit in our result. 
Result so far: 45370.87
Subtracting 3927 from 4020 leaves us with 93.
Since there are no more digits in the dividend, we add a zero to the remainder making it 930, and continue the process.

Advancing to step 11:
561 goes into 930 1 times with a remainder of 369.
The number 1 becomes the next digit in our result. 
Result so far: 45370.871
If we take 561 away from 930, we end up with 369.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3690, and continue the process.

On to step 12:
561 goes into 3690 6 times with a remainder of 324.
The next digit of our result is 6. 
Result so far: 45370.8716
If we take 3366 away from 3690, 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.

Step 13:
The number 561 fits into 3240 5 times, leaving a remainder of 435.
Write down 5 as next digit of the result. 
Result so far: 45370.87165
If we subtract 2805 from 3240, we get 435.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4350, and continue the process.

On to step 14:
The number 561 fits into 4350 7 times, leaving a remainder of 423.
The number 7 becomes the next digit in our result. 
Result so far: 45370.871657
If we subtract 3927 from 4350, we get 423.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4230, and continue the process.

Advancing to step 15:
The number 561 fits into 4230 7 times, leaving a remainder of 303.
Use 7 as the next digit of our solution. 
Result so far: 45370.8716577
Subtracting 3927 from 4230 leaves us with 303.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3030, and continue the process.

The quotient of the division is 45370.8716577, and the remainder is 3.03e-06.
