We're dividing 54480099 by 319 
Our goal is to divide 54480099 by 319.

On to step 1:
When dividing 5 by 319, we get 0 with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Bring next digit (4) of the dividend behind the 5 and repeat the process: 54 / 319

Step 2:
When dividing 54 by 319, we get 0 with a remainder of 54.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 54 to get 54.
Grab the next digit (4) from the dividend, add it to 54, then carry on: 544 / 319

Going ahead to step 3:
The number 319 fits into 544 1 times, leaving a remainder of 225.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 319 away from 544, we end up with 225.
Append the next digit (8) from the dividend to 225 and continue with: 2258 / 319

Let's proceed to step 4:
When dividing 2258 by 319, we get 7 with a remainder of 25.
Put 7 as the next digit of the answer. 
Result so far: 17.0
If we subtract 2233 from 2258, we get 25.
Append the next digit (0) from the dividend to 25 and continue with: 250 / 319

Advancing to step 5:
319 can be fit into 250 0 times, resulting in a remainder of 250.
The next digit of our result is 0. 
Result so far: 170.0
If we subtract 0 from 250, we get 250.
Grab the next digit (0) from the dividend, add it to 250, then carry on: 2500 / 319

Let's proceed to step 6:
If we divide 2500 by 319, we get 7 and a remainder of 267.
Record the quotient 7 as the next digit in the result. 
Result so far: 1707.0
Subtracting 2233 from 2500 leaves us with 267.
Grab the next digit (9) from the dividend, add it to 267, then carry on: 2679 / 319

Moving on to step 7:
2679 divided by 319 is 8 with a remainder of 127.
The next digit of our result is 8. 
Result so far: 17078.0
Subtract 2552 from 2679 to get 127.
Grab the next digit (9) from the dividend, add it to 127, then carry on: 1279 / 319

Advancing to step 8:
319 goes into 1279 4 times with a remainder of 3.
The next digit of our result is 4. 
Result so far: 170784.0
Subtract 1276 from 1279 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 9:
30 divided by 319 is 0 with a remainder of 30.
The next digit of our result is 0. 
Result so far: 170784.0
The remainder is 30 after subtracting 0 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 10:
319 can be fit into 300 0 times, resulting in a remainder of 300.
The next digit of our result is 0. 
Result so far: 170784.0
Deduct 0 from 300 and we're left with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Our division results in 170784.0 with a remaining 0.3.
