Let's divide 8404 by 54
We want to figure out the number of times 8404 can be divided by 54.

Advancing to step 1:
54 goes into 8 0 times with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Append the next digit (4) from the dividend to 8 and continue with: 84 / 54

Advancing to step 2:
When dividing 84 by 54, we get 1 with a remainder of 30.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 54 from 84 and we're left with 30.
Append the next digit (0) from the dividend to 30 and continue with: 300 / 54

On to step 3:
300 divided by 54 is 5 with a remainder of 30.
The next digit of our result is 5. 
Result so far: 15.0
Subtracting 270 from 300 leaves us with 30.
Fetch the next digit (4) from the dividend, attach it to 30 and continue: 304 / 54

Advancing to step 4:
If we divide 304 by 54, we get 5 and a remainder of 34.
Use 5 as the next digit of our solution. 
Result so far: 155.0
Subtract 270 from 304 to get 34.
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 5:
340 divided by 54 is 6 with a remainder of 16.
Write down 6 as next digit of the result. 
Result so far: 155.6
Subtracting 324 from 340 leaves us 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.

Moving on to step 6:
If we divide 160 by 54, we get 2 and a remainder of 52.
Use 2 as the next digit of our solution. 
Result so far: 155.62
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.

On to step 7:
54 goes into 520 9 times with a remainder of 34.
The next digit of our result is 9. 
Result so far: 155.629
If we subtract 486 from 520, we get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Step 8:
The number 54 fits into 340 6 times, leaving a remainder of 16.
Write down 6 as next digit of the result. 
Result so far: 155.6296
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.

Let's proceed to step 9:
54 can be fit into 160 2 times, resulting in a remainder of 52.
The next digit of our result is 2. 
Result so far: 155.62962
If we subtract 108 from 160, we get 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 10:
54 can be fit into 520 9 times, resulting in a remainder of 34.
The next digit of our result is 9. 
Result so far: 155.629629
Deduct 486 from 520 and we're left 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.

Moving on to step 11:
340 divided by 54 is 6 with a remainder of 16.
The next digit of our result is 6. 
Result so far: 155.6296296
Subtract 324 from 340 to get 16.
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 12:
If we divide 160 by 54, we get 2 and a remainder of 52.
Write down 2 as next digit of the result. 
Result so far: 155.62962962
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.

Our division results in 155.62962962 with a remaining 5.2e-08.
