23435402 ÷ 510 
We want to divide 23435402 by 510.

Going ahead to step 1:
The number 510 fits into 2 0 times, leaving a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Bring next digit (3) of the dividend behind the 2 and repeat the process: 23 / 510

Step 2:
If we divide 23 by 510, we get 0 and a remainder of 23.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 23 after subtracting 0 from 23.
Bring next digit (4) of the dividend behind the 23 and repeat the process: 234 / 510

Advancing to step 3:
234 divided by 510 is 0 with a remainder of 234.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 234 leaves us with 234.
Take the next digit (3) from the dividend and append it to 234, then repeat: 2343 / 510

Moving on to step 4:
If we divide 2343 by 510, we get 4 and a remainder of 303.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Deduct 2040 from 2343 and we're left with 303.
Include the next digit (5) from the dividend after 303, then repeat: 3035 / 510

Going ahead to step 5:
The number 510 fits into 3035 5 times, leaving a remainder of 485.
Put 5 as the next digit of the answer. 
Result so far: 45.0
Subtract 2550 from 3035 to get 485.
Fetch the next digit (4) from the dividend, attach it to 485 and continue: 4854 / 510

Moving on to step 6:
4854 divided by 510 is 9 with a remainder of 264.
Use 9 as the next digit of our solution. 
Result so far: 459.0
If we subtract 4590 from 4854, we get 264.
Grab the next digit (0) from the dividend, add it to 264, then carry on: 2640 / 510

On to step 7:
510 can be fit into 2640 5 times, resulting in a remainder of 90.
Write down 5 as next digit of the result. 
Result so far: 4595.0
The remainder is 90 after subtracting 2550 from 2640.
Include the next digit (2) from the dividend after 90, then repeat: 902 / 510

Let's proceed to step 8:
When dividing 902 by 510, we get 1 with a remainder of 392.
Use 1 as the next digit of our solution. 
Result so far: 45951.0
If we take 510 away from 902, we end up with 392.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3920, and continue the process.

On to step 9:
The number 510 fits into 3920 7 times, leaving a remainder of 350.
The number 7 becomes the next digit in our result. 
Result so far: 45951.7
Deduct 3570 from 3920 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.

Let's proceed to step 10:
510 goes into 3500 6 times with a remainder of 440.
The next digit of our result is 6. 
Result so far: 45951.76
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 11:
If we divide 4400 by 510, we get 8 and a remainder of 320.
The next digit of our result is 8. 
Result so far: 45951.768
If we subtract 4080 from 4400, we get 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Let's proceed to step 12:
3200 divided by 510 is 6 with a remainder of 140.
The number 6 becomes the next digit in our result. 
Result so far: 45951.7686
Subtracting 3060 from 3200 leaves us with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

On to step 13:
510 goes into 1400 2 times with a remainder of 380.
Record the quotient 2 as the next digit in the result. 
Result so far: 45951.76862
If we subtract 1020 from 1400, we get 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Moving on to step 14:
When dividing 3800 by 510, we get 7 with a remainder of 230.
Record the quotient 7 as the next digit in the result. 
Result so far: 45951.768627
The remainder is 230 after subtracting 3570 from 3800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

On to step 15:
510 goes into 2300 4 times with a remainder of 260.
The next digit of our result is 4. 
Result so far: 45951.7686274
The remainder is 260 after subtracting 2040 from 2300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

On to step 16:
The number 510 fits into 2600 5 times, leaving a remainder of 50.
Use 5 as the next digit of our solution. 
Result so far: 45951.76862745
Subtract 2550 from 2600 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

After the division, we end up with 45951.76862745 and a remainder of 5e-08.
