553920 ÷ 54 
We're looking to find how many times 54 goes into 553920.

Going ahead to step 1:
When dividing 5 by 54, we get 0 with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Grab the next digit (5) from the dividend, add it to 5, then carry on: 55 / 54

Step 2:
54 goes into 55 1 times with a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 54 from 55 and we're left with 1.
Take the next digit (3) from the dividend and append it to 1, then repeat: 13 / 54

Let's proceed to step 3:
The number 54 fits into 13 0 times, leaving a remainder of 13.
Use 0 as the next digit of our solution. 
Result so far: 10.0
The remainder is 13 after subtracting 0 from 13.
Grab the next digit (9) from the dividend, add it to 13, then carry on: 139 / 54

On to step 4:
139 divided by 54 is 2 with a remainder of 31.
Put 2 as the next digit of the answer. 
Result so far: 102.0
If we subtract 108 from 139, we get 31.
Bring next digit (2) of the dividend behind the 31 and repeat the process: 312 / 54

On to step 5:
312 divided by 54 is 5 with a remainder of 42.
Write down 5 as next digit of the result. 
Result so far: 1025.0
If we take 270 away from 312, we end up with 42.
Append the next digit (0) from the dividend to 42 and continue with: 420 / 54

Moving on to step 6:
When dividing 420 by 54, we get 7 with a remainder of 42.
The number 7 becomes the next digit in our result. 
Result so far: 10257.0
Subtract 378 from 420 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

On to step 7:
420 divided by 54 is 7 with a remainder of 42.
Record the quotient 7 as the next digit in the result. 
Result so far: 10257.7
Subtracting 378 from 420 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Step 8:
If we divide 420 by 54, we get 7 and a remainder of 42.
Write down 7 as next digit of the result. 
Result so far: 10257.77
If we subtract 378 from 420, we get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

The quotient of the division is 10257.77, and the remainder is 0.042.
