We're dividing 54473509 by 510 
We want to figure out the number of times 54473509 can be divided by 510.

Step 1:
510 can be fit into 5 0 times, resulting in a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Grab the next digit (4) from the dividend, add it to 5, then carry on: 54 / 510

Step 2:
The number 510 fits into 54 0 times, leaving a remainder of 54.
Use 0 as the next digit of our solution. 
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 / 510

Step 3:
If we divide 544 by 510, we get 1 and a remainder of 34.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 510 from 544, we get 34.
Fetch the next digit (7) from the dividend, attach it to 34 and continue: 347 / 510

Step 4:
If we divide 347 by 510, we get 0 and a remainder of 347.
The next digit of our result is 0. 
Result so far: 10.0
If we take 0 away from 347, we end up with 347.
Bring next digit (3) of the dividend behind the 347 and repeat the process: 3473 / 510

Advancing to step 5:
When dividing 3473 by 510, we get 6 with a remainder of 413.
The next digit of our result is 6. 
Result so far: 106.0
If we take 3060 away from 3473, we end up with 413.
Fetch the next digit (5) from the dividend, attach it to 413 and continue: 4135 / 510

Advancing to step 6:
If we divide 4135 by 510, we get 8 and a remainder of 55.
The next digit of our result is 8. 
Result so far: 1068.0
If we take 4080 away from 4135, we end up with 55.
Grab the next digit (0) from the dividend, add it to 55, then carry on: 550 / 510

Let's proceed to step 7:
When dividing 550 by 510, we get 1 with a remainder of 40.
Use 1 as the next digit of our solution. 
Result so far: 10681.0
The remainder is 40 after subtracting 510 from 550.
Append the next digit (9) from the dividend to 40 and continue with: 409 / 510

Advancing to step 8:
409 divided by 510 is 0 with a remainder of 409.
The number 0 becomes the next digit in our result. 
Result so far: 106810.0
Deduct 0 from 409 and we're left with 409.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4090, and continue the process.

On to step 9:
4090 divided by 510 is 8 with a remainder of 10.
Write down 8 as next digit of the result. 
Result so far: 106810.8
If we subtract 4080 from 4090, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 10:
100 divided by 510 is 0 with a remainder of 100.
Put 0 as the next digit of the answer. 
Result so far: 106810.8
Subtracting 0 from 100 leaves us with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

On to step 11:
The number 510 fits into 1000 1 times, leaving a remainder of 490.
Write down 1 as next digit of the result. 
Result so far: 106810.801
Deduct 510 from 1000 and we're left with 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4900, and continue the process.

Moving on to step 12:
When dividing 4900 by 510, we get 9 with a remainder of 310.
The number 9 becomes the next digit in our result. 
Result so far: 106810.8019
The remainder is 310 after subtracting 4590 from 4900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

On to step 13:
510 can be fit into 3100 6 times, resulting in a remainder of 40.
The next digit of our result is 6. 
Result so far: 106810.80196
If we take 3060 away from 3100, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 14:
510 goes into 400 0 times with a remainder of 400.
Record the quotient 0 as the next digit in the result. 
Result so far: 106810.80196
Deduct 0 from 400 and we're left with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Step 15:
510 goes into 4000 7 times with a remainder of 430.
The number 7 becomes the next digit in our result. 
Result so far: 106810.8019607
Deduct 3570 from 4000 and we're left with 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4300, and continue the process.

Going ahead to step 16:
510 goes into 4300 8 times with a remainder of 220.
Put 8 as the next digit of the answer. 
Result so far: 106810.80196078
Subtracting 4080 from 4300 leaves us with 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

The final outcome is 106810.80196078, with a leftover of 2.2e-07.
