Let's divide 43691485 by 684
We want to divide 43691485 by 684.

Advancing to step 1:
If we divide 4 by 684, we get 0 and a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Include the next digit (3) from the dividend after 4, then repeat: 43 / 684

Step 2:
43 divided by 684 is 0 with a remainder of 43.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 43 and we're left with 43.
Take the next digit (6) from the dividend and append it to 43, then repeat: 436 / 684

Step 3:
684 can be fit into 436 0 times, resulting in a remainder of 436.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 436, we end up with 436.
Append the next digit (9) from the dividend to 436 and continue with: 4369 / 684

Advancing to step 4:
684 goes into 4369 6 times with a remainder of 265.
Use 6 as the next digit of our solution. 
Result so far: 6.0
The remainder is 265 after subtracting 4104 from 4369.
Append the next digit (1) from the dividend to 265 and continue with: 2651 / 684

Step 5:
If we divide 2651 by 684, we get 3 and a remainder of 599.
The number 3 becomes the next digit in our result. 
Result so far: 63.0
Subtract 2052 from 2651 to get 599.
Grab the next digit (4) from the dividend, add it to 599, then carry on: 5994 / 684

Step 6:
684 goes into 5994 8 times with a remainder of 522.
Record the quotient 8 as the next digit in the result. 
Result so far: 638.0
Subtract 5472 from 5994 to get 522.
Grab the next digit (8) from the dividend, add it to 522, then carry on: 5228 / 684

Let's proceed to step 7:
684 goes into 5228 7 times with a remainder of 440.
The next digit of our result is 7. 
Result so far: 6387.0
If we take 4788 away from 5228, we end up with 440.
Take the next digit (5) from the dividend and append it to 440, then repeat: 4405 / 684

On to step 8:
4405 divided by 684 is 6 with a remainder of 301.
The next digit of our result is 6. 
Result so far: 63876.0
Deduct 4104 from 4405 and we're left with 301.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3010, and continue the process.

Step 9:
684 can be fit into 3010 4 times, resulting in a remainder of 274.
Record the quotient 4 as the next digit in the result. 
Result so far: 63876.4
Subtracting 2736 from 3010 leaves us with 274.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2740, and continue the process.

On to step 10:
684 can be fit into 2740 4 times, resulting in a remainder of 4.
Use 4 as the next digit of our solution. 
Result so far: 63876.44
If we take 2736 away from 2740, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

The quotient of the division is 63876.44, and the remainder is 0.004.
