We look at the division of 13337211 by 561 
We want to figure out the number of times 13337211 can be divided by 561.

Going ahead to step 1:
The number 561 fits into 1 0 times, leaving a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Include the next digit (3) from the dividend after 1, then repeat: 13 / 561

On to step 2:
The number 561 fits into 13 0 times, leaving a remainder of 13.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 13 and we're left with 13.
Take the next digit (3) from the dividend and append it to 13, then repeat: 133 / 561

Step 3:
When dividing 133 by 561, we get 0 with a remainder of 133.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 133 leaves us with 133.
Take the next digit (3) from the dividend and append it to 133, then repeat: 1333 / 561

Moving on to step 4:
1333 divided by 561 is 2 with a remainder of 211.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Deduct 1122 from 1333 and we're left with 211.
Append the next digit (7) from the dividend to 211 and continue with: 2117 / 561

Going ahead to step 5:
The number 561 fits into 2117 3 times, leaving a remainder of 434.
The number 3 becomes the next digit in our result. 
Result so far: 23.0
If we subtract 1683 from 2117, we get 434.
Include the next digit (2) from the dividend after 434, then repeat: 4342 / 561

Let's proceed to step 6:
When dividing 4342 by 561, we get 7 with a remainder of 415.
The next digit of our result is 7. 
Result so far: 237.0
If we take 3927 away from 4342, we end up with 415.
Include the next digit (1) from the dividend after 415, then repeat: 4151 / 561

Let's proceed to step 7:
The number 561 fits into 4151 7 times, leaving a remainder of 224.
The next digit of our result is 7. 
Result so far: 2377.0
Deduct 3927 from 4151 and we're left with 224.
Bring next digit (1) of the dividend behind the 224 and repeat the process: 2241 / 561

Advancing to step 8:
561 can be fit into 2241 3 times, resulting in a remainder of 558.
The number 3 becomes the next digit in our result. 
Result so far: 23773.0
Subtracting 1683 from 2241 leaves us with 558.
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 9:
If we divide 5580 by 561, we get 9 and a remainder of 531.
The number 9 becomes the next digit in our result. 
Result so far: 23773.9
Subtracting 5049 from 5580 leaves us with 531.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5310, and continue the process.

Let's proceed to step 10:
The number 561 fits into 5310 9 times, leaving a remainder of 261.
Use 9 as the next digit of our solution. 
Result so far: 23773.99
Deduct 5049 from 5310 and we're left with 261.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2610, and continue the process.

Our division results in 23773.99 with a remaining 0.261.
