43682864 divided by 210 
We want to divide 43682864 by 210.

Step 1:
If we divide 4 by 210, we get 0 and a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Append the next digit (3) from the dividend to 4 and continue with: 43 / 210

Let's proceed to step 2:
210 goes into 43 0 times with a remainder of 43.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 43 leaves us with 43.
Include the next digit (6) from the dividend after 43, then repeat: 436 / 210

On to step 3:
210 goes into 436 2 times with a remainder of 16.
Write down 2 as next digit of the result. 
Result so far: 2.0
Deduct 420 from 436 and we're left with 16.
Take the next digit (8) from the dividend and append it to 16, then repeat: 168 / 210

Going ahead to step 4:
When dividing 168 by 210, we get 0 with a remainder of 168.
Put 0 as the next digit of the answer. 
Result so far: 20.0
If we subtract 0 from 168, we get 168.
Include the next digit (2) from the dividend after 168, then repeat: 1682 / 210

On to step 5:
If we divide 1682 by 210, we get 8 and a remainder of 2.
The number 8 becomes the next digit in our result. 
Result so far: 208.0
If we subtract 1680 from 1682, we get 2.
Fetch the next digit (8) from the dividend, attach it to 2 and continue: 28 / 210

Going ahead to step 6:
210 goes into 28 0 times with a remainder of 28.
Record the quotient 0 as the next digit in the result. 
Result so far: 2080.0
Subtracting 0 from 28 leaves us with 28.
Include the next digit (6) from the dividend after 28, then repeat: 286 / 210

Step 7:
210 can be fit into 286 1 times, resulting in a remainder of 76.
Use 1 as the next digit of our solution. 
Result so far: 20801.0
If we subtract 210 from 286, we get 76.
Bring next digit (4) of the dividend behind the 76 and repeat the process: 764 / 210

Step 8:
210 can be fit into 764 3 times, resulting in a remainder of 134.
The next digit of our result is 3. 
Result so far: 208013.0
Subtracting 630 from 764 leaves us with 134.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1340, and continue the process.

Advancing to step 9:
The number 210 fits into 1340 6 times, leaving a remainder of 80.
Write down 6 as next digit of the result. 
Result so far: 208013.6
The remainder is 80 after subtracting 1260 from 1340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Going ahead to step 10:
210 can be fit into 800 3 times, resulting in a remainder of 170.
The number 3 becomes the next digit in our result. 
Result so far: 208013.63
The remainder is 170 after subtracting 630 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Step 11:
210 can be fit into 1700 8 times, resulting in a remainder of 20.
Use 8 as the next digit of our solution. 
Result so far: 208013.638
Subtracting 1680 from 1700 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 12:
200 divided by 210 is 0 with a remainder of 200.
Record the quotient 0 as the next digit in the result. 
Result so far: 208013.638
The remainder is 200 after subtracting 0 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Advancing to step 13:
210 goes into 2000 9 times with a remainder of 110.
Record the quotient 9 as the next digit in the result. 
Result so far: 208013.63809
Subtracting 1890 from 2000 leaves us with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Moving on to step 14:
The number 210 fits into 1100 5 times, leaving a remainder of 50.
The next digit of our result is 5. 
Result so far: 208013.638095
If we take 1050 away from 1100, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 15:
The number 210 fits into 500 2 times, leaving a remainder of 80.
The number 2 becomes the next digit in our result. 
Result so far: 208013.6380952
Deduct 420 from 500 and we're left with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Step 16:
When dividing 800 by 210, we get 3 with a remainder of 170.
Write down 3 as next digit of the result. 
Result so far: 208013.63809523
If we subtract 630 from 800, we get 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

The final result is 208013.63809523 with a remainder of 1.7e-07.
