We're dividing 77521743 by 387 
Let's see how many times 387 fits into 77521743.

Moving on to step 1:
When dividing 7 by 387, we get 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Take the next digit (7) from the dividend and append it to 7, then repeat: 77 / 387

Step 2:
If we divide 77 by 387, we get 0 and a remainder of 77.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 77 leaves us with 77.
Take the next digit (5) from the dividend and append it to 77, then repeat: 775 / 387

Moving on to step 3:
387 can be fit into 775 2 times, resulting in a remainder of 1.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we take 774 away from 775, we end up with 1.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 387

Advancing to step 4:
387 can be fit into 12 0 times, resulting in a remainder of 12.
Record the quotient 0 as the next digit in the result. 
Result so far: 20.0
If we take 0 away from 12, we end up with 12.
Include the next digit (1) from the dividend after 12, then repeat: 121 / 387

Going ahead to step 5:
If we divide 121 by 387, we get 0 and a remainder of 121.
Use 0 as the next digit of our solution. 
Result so far: 200.0
Subtracting 0 from 121 leaves us with 121.
Append the next digit (7) from the dividend to 121 and continue with: 1217 / 387

On to step 6:
387 can be fit into 1217 3 times, resulting in a remainder of 56.
The number 3 becomes the next digit in our result. 
Result so far: 2003.0
The remainder is 56 after subtracting 1161 from 1217.
Include the next digit (4) from the dividend after 56, then repeat: 564 / 387

On to step 7:
387 can be fit into 564 1 times, resulting in a remainder of 177.
The next digit of our result is 1. 
Result so far: 20031.0
If we subtract 387 from 564, we get 177.
Take the next digit (3) from the dividend and append it to 177, then repeat: 1773 / 387

Advancing to step 8:
1773 divided by 387 is 4 with a remainder of 225.
The next digit of our result is 4. 
Result so far: 200314.0
If we subtract 1548 from 1773, we get 225.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2250, and continue the process.

Advancing to step 9:
2250 divided by 387 is 5 with a remainder of 315.
The number 5 becomes the next digit in our result. 
Result so far: 200314.5
Deduct 1935 from 2250 and we're left with 315.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3150, and continue the process.

On to step 10:
The number 387 fits into 3150 8 times, leaving a remainder of 54.
Write down 8 as next digit of the result. 
Result so far: 200314.58
Subtract 3096 from 3150 to get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Moving on to step 11:
387 goes into 540 1 times with a remainder of 153.
The next digit of our result is 1. 
Result so far: 200314.581
If we take 387 away from 540, we end up with 153.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1530, and continue the process.

Going ahead to step 12:
1530 divided by 387 is 3 with a remainder of 369.
Use 3 as the next digit of our solution. 
Result so far: 200314.5813
Subtract 1161 from 1530 to get 369.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3690, and continue the process.

Let's proceed to step 13:
When dividing 3690 by 387, we get 9 with a remainder of 207.
The number 9 becomes the next digit in our result. 
Result so far: 200314.58139
Deduct 3483 from 3690 and we're left with 207.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2070, and continue the process.

Let's proceed to step 14:
If we divide 2070 by 387, we get 5 and a remainder of 135.
The number 5 becomes the next digit in our result. 
Result so far: 200314.581395
Subtracting 1935 from 2070 leaves us with 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

Moving on to step 15:
The number 387 fits into 1350 3 times, leaving a remainder of 189.
The next digit of our result is 3. 
Result so far: 200314.5813953
If we subtract 1161 from 1350, we get 189.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1890, and continue the process.

Let's proceed to step 16:
387 can be fit into 1890 4 times, resulting in a remainder of 342.
The number 4 becomes the next digit in our result. 
Result so far: 200314.58139534
If we subtract 1548 from 1890, we get 342.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3420, and continue the process.

After the division, we end up with 200314.58139534 and a remainder of 3.42e-07.
