We divide 400480 by 54
Let's see how many times 54 fits into 400480.

Advancing to step 1:
4 divided by 54 is 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Grab the next digit (0) from the dividend, add it to 4, then carry on: 40 / 54

Advancing to step 2:
If we divide 40 by 54, we get 0 and a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 40 leaves us with 40.
Take the next digit (0) from the dividend and append it to 40, then repeat: 400 / 54

Moving on to step 3:
400 divided by 54 is 7 with a remainder of 22.
Put 7 as the next digit of the answer. 
Result so far: 7.0
Subtracting 378 from 400 leaves us with 22.
Take the next digit (4) from the dividend and append it to 22, then repeat: 224 / 54

Moving on to step 4:
224 divided by 54 is 4 with a remainder of 8.
Put 4 as the next digit of the answer. 
Result so far: 74.0
Subtract 216 from 224 to get 8.
Bring next digit (8) of the dividend behind the 8 and repeat the process: 88 / 54

Moving on to step 5:
The number 54 fits into 88 1 times, leaving a remainder of 34.
Record the quotient 1 as the next digit in the result. 
Result so far: 741.0
Subtract 54 from 88 to get 34.
Fetch the next digit (0) from the dividend, attach it to 34 and continue: 340 / 54

Going ahead to step 6:
If we divide 340 by 54, we get 6 and a remainder of 16.
Write down 6 as next digit of the result. 
Result so far: 7416.0
If we take 324 away from 340, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 7:
The number 54 fits into 160 2 times, leaving a remainder of 52.
Record the quotient 2 as the next digit in the result. 
Result so far: 7416.2
Deduct 108 from 160 and we're left with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

On to step 8:
54 can be fit into 520 9 times, resulting in a remainder of 34.
The number 9 becomes the next digit in our result. 
Result so far: 7416.29
If we take 486 away from 520, we end up with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Going ahead to step 9:
54 can be fit into 340 6 times, resulting in a remainder of 16.
Write down 6 as next digit of the result. 
Result so far: 7416.296
The remainder is 16 after subtracting 324 from 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 10:
160 divided by 54 is 2 with a remainder of 52.
The next digit of our result is 2. 
Result so far: 7416.2962
If we take 108 away from 160, we end up with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Moving on to step 11:
54 goes into 520 9 times with a remainder of 34.
Record the quotient 9 as the next digit in the result. 
Result so far: 7416.29629
The remainder is 34 after subtracting 486 from 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Moving on to step 12:
340 divided by 54 is 6 with a remainder of 16.
The number 6 becomes the next digit in our result. 
Result so far: 7416.296296
The remainder is 16 after subtracting 324 from 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 13:
54 can be fit into 160 2 times, resulting in a remainder of 52.
Use 2 as the next digit of our solution. 
Result so far: 7416.2962962
The remainder is 52 after subtracting 108 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

On to step 14:
54 can be fit into 520 9 times, resulting in a remainder of 34.
Write down 9 as next digit of the result. 
Result so far: 7416.29629629
Subtracting 486 from 520 leaves us with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

The final result is 7416.29629629 with a remainder of 3.4e-08.
