Let's divide 43155503 by 387
Let's see how many times 387 fits into 43155503.

On to step 1:
387 goes into 4 0 times with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Include the next digit (3) from the dividend after 4, then repeat: 43 / 387

Advancing to step 2:
The number 387 fits into 43 0 times, leaving a remainder of 43.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 43 and we're left with 43.
Bring next digit (1) of the dividend behind the 43 and repeat the process: 431 / 387

Step 3:
431 divided by 387 is 1 with a remainder of 44.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 387 from 431 and we're left with 44.
Grab the next digit (5) from the dividend, add it to 44, then carry on: 445 / 387

Advancing to step 4:
When dividing 445 by 387, we get 1 with a remainder of 58.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
If we take 387 away from 445, we end up with 58.
Take the next digit (5) from the dividend and append it to 58, then repeat: 585 / 387

On to step 5:
585 divided by 387 is 1 with a remainder of 198.
The next digit of our result is 1. 
Result so far: 111.0
Subtracting 387 from 585 leaves us with 198.
Take the next digit (5) from the dividend and append it to 198, then repeat: 1985 / 387

Going ahead to step 6:
387 can be fit into 1985 5 times, resulting in a remainder of 50.
The next digit of our result is 5. 
Result so far: 1115.0
If we subtract 1935 from 1985, we get 50.
Grab the next digit (0) from the dividend, add it to 50, then carry on: 500 / 387

On to step 7:
If we divide 500 by 387, we get 1 and a remainder of 113.
Write down 1 as next digit of the result. 
Result so far: 11151.0
Subtract 387 from 500 to get 113.
Append the next digit (3) from the dividend to 113 and continue with: 1133 / 387

On to step 8:
The number 387 fits into 1133 2 times, leaving a remainder of 359.
The number 2 becomes the next digit in our result. 
Result so far: 111512.0
Deduct 774 from 1133 and we're left with 359.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3590, and continue the process.

Advancing to step 9:
387 goes into 3590 9 times with a remainder of 107.
Write down 9 as next digit of the result. 
Result so far: 111512.9
Deduct 3483 from 3590 and we're left with 107.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1070, and continue the process.

Step 10:
387 goes into 1070 2 times with a remainder of 296.
Put 2 as the next digit of the answer. 
Result so far: 111512.92
If we take 774 away from 1070, we end up with 296.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2960, and continue the process.

Let's proceed to step 11:
The number 387 fits into 2960 7 times, leaving a remainder of 251.
The number 7 becomes the next digit in our result. 
Result so far: 111512.927
If we take 2709 away from 2960, we end up with 251.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2510, and continue the process.

Let's proceed to step 12:
The number 387 fits into 2510 6 times, leaving a remainder of 188.
Record the quotient 6 as the next digit in the result. 
Result so far: 111512.9276
Deduct 2322 from 2510 and we're left with 188.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1880, and continue the process.

Moving on to step 13:
387 goes into 1880 4 times with a remainder of 332.
Write down 4 as next digit of the result. 
Result so far: 111512.92764
If we take 1548 away from 1880, we end up with 332.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3320, and continue the process.

Step 14:
3320 divided by 387 is 8 with a remainder of 224.
Write down 8 as next digit of the result. 
Result so far: 111512.927648
If we subtract 3096 from 3320, we get 224.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

Moving on to step 15:
If we divide 2240 by 387, we get 5 and a remainder of 305.
The number 5 becomes the next digit in our result. 
Result so far: 111512.9276485
Deduct 1935 from 2240 and we're left with 305.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3050, and continue the process.

Going ahead to step 16:
3050 divided by 387 is 7 with a remainder of 341.
The number 7 becomes the next digit in our result. 
Result so far: 111512.92764857
Deduct 2709 from 3050 and we're left with 341.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3410, and continue the process.

Our division results in 111512.92764857 with a remaining 3.41e-07.
