We're dividing 18100175 by 510 
We want to figure out the number of times 18100175 can be divided by 510.

Step 1:
The number 510 fits into 1 0 times, leaving a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Grab the next digit (8) from the dividend, add it to 1, then carry on: 18 / 510

Step 2:
18 divided by 510 is 0 with a remainder of 18.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 18 leaves us with 18.
Include the next digit (1) from the dividend after 18, then repeat: 181 / 510

On to step 3:
181 divided by 510 is 0 with a remainder of 181.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 181 leaves us with 181.
Grab the next digit (0) from the dividend, add it to 181, then carry on: 1810 / 510

Moving on to step 4:
When dividing 1810 by 510, we get 3 with a remainder of 280.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtracting 1530 from 1810 leaves us with 280.
Grab the next digit (0) from the dividend, add it to 280, then carry on: 2800 / 510

Let's proceed to step 5:
The number 510 fits into 2800 5 times, leaving a remainder of 250.
The number 5 becomes the next digit in our result. 
Result so far: 35.0
Subtracting 2550 from 2800 leaves us with 250.
Include the next digit (1) from the dividend after 250, then repeat: 2501 / 510

Advancing to step 6:
510 goes into 2501 4 times with a remainder of 461.
Write down 4 as next digit of the result. 
Result so far: 354.0
Subtracting 2040 from 2501 leaves us with 461.
Include the next digit (7) from the dividend after 461, then repeat: 4617 / 510

Let's proceed to step 7:
When dividing 4617 by 510, we get 9 with a remainder of 27.
The number 9 becomes the next digit in our result. 
Result so far: 3549.0
If we take 4590 away from 4617, we end up with 27.
Fetch the next digit (5) from the dividend, attach it to 27 and continue: 275 / 510

On to step 8:
510 can be fit into 275 0 times, resulting in a remainder of 275.
Use 0 as the next digit of our solution. 
Result so far: 35490.0
Deduct 0 from 275 and we're left with 275.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2750, and continue the process.

Step 9:
510 goes into 2750 5 times with a remainder of 200.
The next digit of our result is 5. 
Result so far: 35490.5
If we subtract 2550 from 2750, we get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Moving on to step 10:
510 can be fit into 2000 3 times, resulting in a remainder of 470.
The next digit of our result is 3. 
Result so far: 35490.53
Deduct 1530 from 2000 and we're left with 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4700, and continue the process.

Step 11:
510 can be fit into 4700 9 times, resulting in a remainder of 110.
Record the quotient 9 as the next digit in the result. 
Result so far: 35490.539
Deduct 4590 from 4700 and we're left with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Moving on to step 12:
The number 510 fits into 1100 2 times, leaving a remainder of 80.
Put 2 as the next digit of the answer. 
Result so far: 35490.5392
Deduct 1020 from 1100 and we're left with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Going ahead to step 13:
510 can be fit into 800 1 times, resulting in a remainder of 290.
Record the quotient 1 as the next digit in the result. 
Result so far: 35490.53921
Deduct 510 from 800 and we're left with 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

Advancing to step 14:
510 can be fit into 2900 5 times, resulting in a remainder of 350.
Use 5 as the next digit of our solution. 
Result so far: 35490.539215
Deduct 2550 from 2900 and we're left with 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

Step 15:
3500 divided by 510 is 6 with a remainder of 440.
Use 6 as the next digit of our solution. 
Result so far: 35490.5392156
Deduct 3060 from 3500 and we're left with 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

On to step 16:
4400 divided by 510 is 8 with a remainder of 320.
The next digit of our result is 8. 
Result so far: 35490.53921568
If we take 4080 away from 4400, we end up with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

After the division, we end up with 35490.53921568 and a remainder of 3.2e-07.
