76587129 ÷ 381 
We want to divide 76587129 by 381.

Moving on to step 1:
381 can be fit into 7 0 times, resulting in a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Bring next digit (6) of the dividend behind the 7 and repeat the process: 76 / 381

Step 2:
381 goes into 76 0 times with a remainder of 76.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 76 to get 76.
Include the next digit (5) from the dividend after 76, then repeat: 765 / 381

Step 3:
381 can be fit into 765 2 times, resulting in a remainder of 3.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we subtract 762 from 765, we get 3.
Fetch the next digit (8) from the dividend, attach it to 3 and continue: 38 / 381

Let's proceed to step 4:
If we divide 38 by 381, we get 0 and a remainder of 38.
The number 0 becomes the next digit in our result. 
Result so far: 20.0
Subtract 0 from 38 to get 38.
Take the next digit (7) from the dividend and append it to 38, then repeat: 387 / 381

On to step 5:
When dividing 387 by 381, we get 1 with a remainder of 6.
The next digit of our result is 1. 
Result so far: 201.0
Subtracting 381 from 387 leaves us with 6.
Append the next digit (1) from the dividend to 6 and continue with: 61 / 381

On to step 6:
If we divide 61 by 381, we get 0 and a remainder of 61.
The number 0 becomes the next digit in our result. 
Result so far: 2010.0
Subtracting 0 from 61 leaves us with 61.
Bring next digit (2) of the dividend behind the 61 and repeat the process: 612 / 381

Advancing to step 7:
If we divide 612 by 381, we get 1 and a remainder of 231.
Put 1 as the next digit of the answer. 
Result so far: 20101.0
If we subtract 381 from 612, we get 231.
Include the next digit (9) from the dividend after 231, then repeat: 2319 / 381

Moving on to step 8:
When dividing 2319 by 381, we get 6 with a remainder of 33.
Record the quotient 6 as the next digit in the result. 
Result so far: 201016.0
The remainder is 33 after subtracting 2286 from 2319.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Advancing to step 9:
381 can be fit into 330 0 times, resulting in a remainder of 330.
Write down 0 as next digit of the result. 
Result so far: 201016.0
Subtract 0 from 330 to get 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

On to step 10:
When dividing 3300 by 381, we get 8 with a remainder of 252.
The next digit of our result is 8. 
Result so far: 201016.08
Subtracting 3048 from 3300 leaves us with 252.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2520, and continue the process.

Moving on to step 11:
If we divide 2520 by 381, we get 6 and a remainder of 234.
Write down 6 as next digit of the result. 
Result so far: 201016.086
If we subtract 2286 from 2520, we get 234.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2340, and continue the process.

On to step 12:
381 goes into 2340 6 times with a remainder of 54.
The number 6 becomes the next digit in our result. 
Result so far: 201016.0866
Deduct 2286 from 2340 and we're left with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

The quotient of the division is 201016.0866, and the remainder is 0.00054.
