43242035 ÷ 686 
Our goal is to divide 43242035 by 686.

Let's proceed to step 1:
4 divided by 686 is 0 with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Grab the next digit (3) from the dividend, add it to 4, then carry on: 43 / 686

Advancing to step 2:
When dividing 43 by 686, we get 0 with a remainder of 43.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 43, we get 43.
Take the next digit (2) from the dividend and append it to 43, then repeat: 432 / 686

Step 3:
If we divide 432 by 686, we get 0 and a remainder of 432.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 432 and we're left with 432.
Take the next digit (4) from the dividend and append it to 432, then repeat: 4324 / 686

Advancing to step 4:
The number 686 fits into 4324 6 times, leaving a remainder of 208.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
Subtracting 4116 from 4324 leaves us with 208.
Fetch the next digit (2) from the dividend, attach it to 208 and continue: 2082 / 686

Going ahead to step 5:
686 can be fit into 2082 3 times, resulting in a remainder of 24.
Write down 3 as next digit of the result. 
Result so far: 63.0
Subtract 2058 from 2082 to get 24.
Take the next digit (0) from the dividend and append it to 24, then repeat: 240 / 686

On to step 6:
686 can be fit into 240 0 times, resulting in a remainder of 240.
The number 0 becomes the next digit in our result. 
Result so far: 630.0
Deduct 0 from 240 and we're left with 240.
Bring next digit (3) of the dividend behind the 240 and repeat the process: 2403 / 686

Going ahead to step 7:
When dividing 2403 by 686, we get 3 with a remainder of 345.
Use 3 as the next digit of our solution. 
Result so far: 6303.0
If we subtract 2058 from 2403, we get 345.
Include the next digit (5) from the dividend after 345, then repeat: 3455 / 686

Step 8:
3455 divided by 686 is 5 with a remainder of 25.
Write down 5 as next digit of the result. 
Result so far: 63035.0
Subtracting 3430 from 3455 leaves us with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

On to step 9:
When dividing 250 by 686, we get 0 with a remainder of 250.
Use 0 as the next digit of our solution. 
Result so far: 63035.0
Subtracting 0 from 250 leaves us with 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Let's proceed to step 10:
686 can be fit into 2500 3 times, resulting in a remainder of 442.
The number 3 becomes the next digit in our result. 
Result so far: 63035.03
Deduct 2058 from 2500 and we're left with 442.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4420, and continue the process.

Step 11:
686 can be fit into 4420 6 times, resulting in a remainder of 304.
Put 6 as the next digit of the answer. 
Result so far: 63035.036
Subtracting 4116 from 4420 leaves us with 304.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

Let's proceed to step 12:
If we divide 3040 by 686, we get 4 and a remainder of 296.
Put 4 as the next digit of the answer. 
Result so far: 63035.0364
If we take 2744 away from 3040, 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.

Step 13:
686 goes into 2960 4 times with a remainder of 216.
The next digit of our result is 4. 
Result so far: 63035.03644
If we subtract 2744 from 2960, we get 216.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

The final result is 63035.03644 with a remainder of 0.000216.
