We're dividing 54241151 by 509 
We want to divide 54241151 by 509.

Step 1:
When dividing 5 by 509, we get 0 with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Grab the next digit (4) from the dividend, add it to 5, then carry on: 54 / 509

On to step 2:
509 goes into 54 0 times with a remainder of 54.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 54 and we're left with 54.
Bring next digit (2) of the dividend behind the 54 and repeat the process: 542 / 509

Moving on to step 3:
If we divide 542 by 509, we get 1 and a remainder of 33.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 509 from 542 and we're left with 33.
Fetch the next digit (4) from the dividend, attach it to 33 and continue: 334 / 509

Step 4:
If we divide 334 by 509, we get 0 and a remainder of 334.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
The remainder is 334 after subtracting 0 from 334.
Fetch the next digit (1) from the dividend, attach it to 334 and continue: 3341 / 509

Step 5:
509 goes into 3341 6 times with a remainder of 287.
Put 6 as the next digit of the answer. 
Result so far: 106.0
Subtract 3054 from 3341 to get 287.
Grab the next digit (1) from the dividend, add it to 287, then carry on: 2871 / 509

Let's proceed to step 6:
2871 divided by 509 is 5 with a remainder of 326.
Use 5 as the next digit of our solution. 
Result so far: 1065.0
The remainder is 326 after subtracting 2545 from 2871.
Take the next digit (5) from the dividend and append it to 326, then repeat: 3265 / 509

Moving on to step 7:
The number 509 fits into 3265 6 times, leaving a remainder of 211.
The number 6 becomes the next digit in our result. 
Result so far: 10656.0
Deduct 3054 from 3265 and we're left with 211.
Fetch the next digit (1) from the dividend, attach it to 211 and continue: 2111 / 509

On to step 8:
If we divide 2111 by 509, we get 4 and a remainder of 75.
Write down 4 as next digit of the result. 
Result so far: 106564.0
If we subtract 2036 from 2111, we get 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Going ahead to step 9:
509 can be fit into 750 1 times, resulting in a remainder of 241.
Use 1 as the next digit of our solution. 
Result so far: 106564.1
If we subtract 509 from 750, we get 241.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2410, and continue the process.

On to step 10:
509 goes into 2410 4 times with a remainder of 374.
The number 4 becomes the next digit in our result. 
Result so far: 106564.14
If we subtract 2036 from 2410, we get 374.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3740, and continue the process.

Going ahead to step 11:
509 can be fit into 3740 7 times, resulting in a remainder of 177.
Put 7 as the next digit of the answer. 
Result so far: 106564.147
If we subtract 3563 from 3740, we get 177.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1770, and continue the process.

Going ahead to step 12:
The number 509 fits into 1770 3 times, leaving a remainder of 243.
The next digit of our result is 3. 
Result so far: 106564.1473
If we take 1527 away from 1770, we end up with 243.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2430, and continue the process.

Advancing to step 13:
509 goes into 2430 4 times with a remainder of 394.
Write down 4 as next digit of the result. 
Result so far: 106564.14734
The remainder is 394 after subtracting 2036 from 2430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3940, and continue the process.

Advancing to step 14:
509 can be fit into 3940 7 times, resulting in a remainder of 377.
Use 7 as the next digit of our solution. 
Result so far: 106564.147347
If we subtract 3563 from 3940, we get 377.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3770, and continue the process.

Going ahead to step 15:
509 goes into 3770 7 times with a remainder of 207.
Use 7 as the next digit of our solution. 
Result so far: 106564.1473477
If we subtract 3563 from 3770, we get 207.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2070, and continue the process.

The final outcome is 106564.1473477, with a leftover of 2.07e-06.
