561771 divided by 54 
We're looking to find how many times 54 goes into 561771.

Moving on to step 1:
54 goes into 5 0 times with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Fetch the next digit (6) from the dividend, attach it to 5 and continue: 56 / 54

Moving on to step 2:
54 can be fit into 56 1 times, resulting in a remainder of 2.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 54 from 56 to get 2.
Append the next digit (1) from the dividend to 2 and continue with: 21 / 54

Step 3:
When dividing 21 by 54, we get 0 with a remainder of 21.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
The remainder is 21 after subtracting 0 from 21.
Bring next digit (7) of the dividend behind the 21 and repeat the process: 217 / 54

On to step 4:
When dividing 217 by 54, we get 4 with a remainder of 1.
Record the quotient 4 as the next digit in the result. 
Result so far: 104.0
Subtracting 216 from 217 leaves us with 1.
Append the next digit (7) from the dividend to 1 and continue with: 17 / 54

On to step 5:
17 divided by 54 is 0 with a remainder of 17.
Use 0 as the next digit of our solution. 
Result so far: 1040.0
If we take 0 away from 17, we end up with 17.
Fetch the next digit (1) from the dividend, attach it to 17 and continue: 171 / 54

Moving on to step 6:
54 goes into 171 3 times with a remainder of 9.
Write down 3 as next digit of the result. 
Result so far: 10403.0
If we subtract 162 from 171, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 7:
54 can be fit into 90 1 times, resulting in a remainder of 36.
Put 1 as the next digit of the answer. 
Result so far: 10403.1
If we take 54 away from 90, we end up with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 8:
The number 54 fits into 360 6 times, leaving a remainder of 36.
The next digit of our result is 6. 
Result so far: 10403.16
The remainder is 36 after subtracting 324 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Moving on to step 9:
360 divided by 54 is 6 with a remainder of 36.
Write down 6 as next digit of the result. 
Result so far: 10403.166
Subtracting 324 from 360 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

The final outcome is 10403.166, with a leftover of 0.0036.
