43976642 ÷ 387 
We want to divide 43976642 by 387.

Going ahead to step 1:
387 goes into 4 0 times with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Append the next digit (3) from the dividend to 4 and continue with: 43 / 387

Step 2:
If we divide 43 by 387, we get 0 and a remainder of 43.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 43, we end up with 43.
Fetch the next digit (9) from the dividend, attach it to 43 and continue: 439 / 387

On to step 3:
The number 387 fits into 439 1 times, leaving a remainder of 52.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 387 from 439 leaves us with 52.
Include the next digit (7) from the dividend after 52, then repeat: 527 / 387

Let's proceed to step 4:
387 can be fit into 527 1 times, resulting in a remainder of 140.
Use 1 as the next digit of our solution. 
Result so far: 11.0
If we subtract 387 from 527, we get 140.
Append the next digit (6) from the dividend to 140 and continue with: 1406 / 387

On to step 5:
387 goes into 1406 3 times with a remainder of 245.
Record the quotient 3 as the next digit in the result. 
Result so far: 113.0
If we subtract 1161 from 1406, we get 245.
Fetch the next digit (6) from the dividend, attach it to 245 and continue: 2456 / 387

Moving on to step 6:
387 can be fit into 2456 6 times, resulting in a remainder of 134.
The number 6 becomes the next digit in our result. 
Result so far: 1136.0
Subtracting 2322 from 2456 leaves us with 134.
Fetch the next digit (4) from the dividend, attach it to 134 and continue: 1344 / 387

Moving on to step 7:
387 goes into 1344 3 times with a remainder of 183.
Use 3 as the next digit of our solution. 
Result so far: 11363.0
Deduct 1161 from 1344 and we're left with 183.
Include the next digit (2) from the dividend after 183, then repeat: 1832 / 387

Advancing to step 8:
The number 387 fits into 1832 4 times, leaving a remainder of 284.
Use 4 as the next digit of our solution. 
Result so far: 113634.0
Deduct 1548 from 1832 and we're left with 284.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2840, and continue the process.

Let's proceed to step 9:
387 goes into 2840 7 times with a remainder of 131.
Record the quotient 7 as the next digit in the result. 
Result so far: 113634.7
Subtracting 2709 from 2840 leaves us with 131.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1310, and continue the process.

Moving on to step 10:
1310 divided by 387 is 3 with a remainder of 149.
Write down 3 as next digit of the result. 
Result so far: 113634.73
Subtracting 1161 from 1310 leaves us with 149.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1490, and continue the process.

Advancing to step 11:
The number 387 fits into 1490 3 times, leaving a remainder of 329.
The number 3 becomes the next digit in our result. 
Result so far: 113634.733
The remainder is 329 after subtracting 1161 from 1490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3290, and continue the process.

The quotient of the division is 113634.733, and the remainder is 0.0329.
