76850443 ÷ 510 
We're looking to find how many times 510 goes into 76850443.

Moving on to step 1:
The number 510 fits into 7 0 times, leaving a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Take the next digit (6) from the dividend and append it to 7, then repeat: 76 / 510

Step 2:
510 goes into 76 0 times with a remainder of 76.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 76 and we're left with 76.
Include the next digit (8) from the dividend after 76, then repeat: 768 / 510

Going ahead to step 3:
768 divided by 510 is 1 with a remainder of 258.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 510 from 768 to get 258.
Fetch the next digit (5) from the dividend, attach it to 258 and continue: 2585 / 510

Advancing to step 4:
510 can be fit into 2585 5 times, resulting in a remainder of 35.
Record the quotient 5 as the next digit in the result. 
Result so far: 15.0
Subtract 2550 from 2585 to get 35.
Fetch the next digit (0) from the dividend, attach it to 35 and continue: 350 / 510

Going ahead to step 5:
The number 510 fits into 350 0 times, leaving a remainder of 350.
Use 0 as the next digit of our solution. 
Result so far: 150.0
If we take 0 away from 350, we end up with 350.
Grab the next digit (4) from the dividend, add it to 350, then carry on: 3504 / 510

Going ahead to step 6:
510 goes into 3504 6 times with a remainder of 444.
Write down 6 as next digit of the result. 
Result so far: 1506.0
Deduct 3060 from 3504 and we're left with 444.
Grab the next digit (4) from the dividend, add it to 444, then carry on: 4444 / 510

Step 7:
If we divide 4444 by 510, we get 8 and a remainder of 364.
Record the quotient 8 as the next digit in the result. 
Result so far: 15068.0
If we subtract 4080 from 4444, we get 364.
Include the next digit (3) from the dividend after 364, then repeat: 3643 / 510

Step 8:
3643 divided by 510 is 7 with a remainder of 73.
The number 7 becomes the next digit in our result. 
Result so far: 150687.0
The remainder is 73 after subtracting 3570 from 3643.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Let's proceed to step 9:
If we divide 730 by 510, we get 1 and a remainder of 220.
Record the quotient 1 as the next digit in the result. 
Result so far: 150687.1
Subtracting 510 from 730 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.

Advancing to step 10:
If we divide 2200 by 510, we get 4 and a remainder of 160.
Write down 4 as next digit of the result. 
Result so far: 150687.14
If we subtract 2040 from 2200, we get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Step 11:
1600 divided by 510 is 3 with a remainder of 70.
Record the quotient 3 as the next digit in the result. 
Result so far: 150687.143
Subtract 1530 from 1600 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

On to step 12:
When dividing 700 by 510, we get 1 with a remainder of 190.
Write down 1 as next digit of the result. 
Result so far: 150687.1431
Subtract 510 from 700 to get 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

On to step 13:
1900 divided by 510 is 3 with a remainder of 370.
Put 3 as the next digit of the answer. 
Result so far: 150687.14313
The remainder is 370 after subtracting 1530 from 1900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3700, and continue the process.

On to step 14:
When dividing 3700 by 510, we get 7 with a remainder of 130.
The number 7 becomes the next digit in our result. 
Result so far: 150687.143137
Subtract 3570 from 3700 to get 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Moving on to step 15:
When dividing 1300 by 510, we get 2 with a remainder of 280.
Use 2 as the next digit of our solution. 
Result so far: 150687.1431372
Subtract 1020 from 1300 to get 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Going ahead to step 16:
If we divide 2800 by 510, we get 5 and a remainder of 250.
Record the quotient 5 as the next digit in the result. 
Result so far: 150687.14313725
If we subtract 2550 from 2800, we get 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

After the division, we end up with 150687.14313725 and a remainder of 2.5e-07.
