782800 ÷ 54 
We want to figure out the number of times 782800 can be divided by 54.

On to step 1:
The number 54 fits into 7 0 times, leaving a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Append the next digit (8) from the dividend to 7 and continue with: 78 / 54

Let's proceed to step 2:
54 can be fit into 78 1 times, resulting in a remainder of 24.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 54 from 78 to get 24.
Bring next digit (2) of the dividend behind the 24 and repeat the process: 242 / 54

Let's proceed to step 3:
54 can be fit into 242 4 times, resulting in a remainder of 26.
Record the quotient 4 as the next digit in the result. 
Result so far: 14.0
Deduct 216 from 242 and we're left with 26.
Include the next digit (8) from the dividend after 26, then repeat: 268 / 54

On to step 4:
When dividing 268 by 54, we get 4 with a remainder of 52.
Put 4 as the next digit of the answer. 
Result so far: 144.0
If we subtract 216 from 268, we get 52.
Append the next digit (0) from the dividend to 52 and continue with: 520 / 54

Going ahead to step 5:
The number 54 fits into 520 9 times, leaving a remainder of 34.
Use 9 as the next digit of our solution. 
Result so far: 1449.0
If we subtract 486 from 520, we get 34.
Grab the next digit (0) from the dividend, add it to 34, then carry on: 340 / 54

Step 6:
If we divide 340 by 54, we get 6 and a remainder of 16.
Record the quotient 6 as the next digit in the result. 
Result so far: 14496.0
Deduct 324 from 340 and we're left 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.

Advancing to step 7:
When dividing 160 by 54, we get 2 with a remainder of 52.
Write down 2 as next digit of the result. 
Result so far: 14496.2
Subtracting 108 from 160 leaves us 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:
The number 54 fits into 520 9 times, leaving a remainder of 34.
Record the quotient 9 as the next digit in the result. 
Result so far: 14496.29
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.

Moving on to step 9:
If we divide 340 by 54, we get 6 and a remainder of 16.
The number 6 becomes the next digit in our result. 
Result so far: 14496.296
If we subtract 324 from 340, we 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.

Step 10:
When dividing 160 by 54, we get 2 with a remainder of 52.
Use 2 as the next digit of our solution. 
Result so far: 14496.2962
Subtract 108 from 160 to 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.

Going ahead to step 11:
When dividing 520 by 54, we get 9 with a remainder of 34.
Put 9 as the next digit of the answer. 
Result so far: 14496.29629
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.

Advancing to step 12:
54 can be fit into 340 6 times, resulting in a remainder of 16.
Use 6 as the next digit of our solution. 
Result so far: 14496.296296
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.

Moving on to step 13:
If we divide 160 by 54, we get 2 and a remainder of 52.
Put 2 as the next digit of the answer. 
Result so far: 14496.2962962
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.

Moving on to step 14:
520 divided by 54 is 9 with a remainder of 34.
Put 9 as the next digit of the answer. 
Result so far: 14496.29629629
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.

The final outcome is 14496.29629629, with a leftover of 3.4e-08.
