We're dividing 43572001 by 336 
Let's see how many times 336 fits into 43572001.

Going ahead to step 1:
The number 336 fits into 4 0 times, leaving 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.
Take the next digit (3) from the dividend and append it to 4, then repeat: 43 / 336

Step 2:
The number 336 fits into 43 0 times, leaving a remainder of 43.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 43 leaves us with 43.
Include the next digit (5) from the dividend after 43, then repeat: 435 / 336

Moving on to step 3:
The number 336 fits into 435 1 times, leaving a remainder of 99.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 336 away from 435, we end up with 99.
Fetch the next digit (7) from the dividend, attach it to 99 and continue: 997 / 336

Moving on to step 4:
If we divide 997 by 336, we get 2 and a remainder of 325.
The next digit of our result is 2. 
Result so far: 12.0
If we take 672 away from 997, we end up with 325.
Append the next digit (2) from the dividend to 325 and continue with: 3252 / 336

Let's proceed to step 5:
336 can be fit into 3252 9 times, resulting in a remainder of 228.
The number 9 becomes the next digit in our result. 
Result so far: 129.0
Deduct 3024 from 3252 and we're left with 228.
Fetch the next digit (0) from the dividend, attach it to 228 and continue: 2280 / 336

Advancing to step 6:
336 can be fit into 2280 6 times, resulting in a remainder of 264.
Record the quotient 6 as the next digit in the result. 
Result so far: 1296.0
If we take 2016 away from 2280, we end up with 264.
Bring next digit (0) of the dividend behind the 264 and repeat the process: 2640 / 336

Going ahead to step 7:
336 goes into 2640 7 times with a remainder of 288.
Write down 7 as next digit of the result. 
Result so far: 12967.0
If we subtract 2352 from 2640, we get 288.
Grab the next digit (1) from the dividend, add it to 288, then carry on: 2881 / 336

Moving on to step 8:
336 goes into 2881 8 times with a remainder of 193.
The next digit of our result is 8. 
Result so far: 129678.0
If we subtract 2688 from 2881, we get 193.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1930, and continue the process.

Let's proceed to step 9:
336 goes into 1930 5 times with a remainder of 250.
The next digit of our result is 5. 
Result so far: 129678.5
Subtracting 1680 from 1930 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.

Advancing to step 10:
If we divide 2500 by 336, we get 7 and a remainder of 148.
Use 7 as the next digit of our solution. 
Result so far: 129678.57
Deduct 2352 from 2500 and we're left with 148.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

Going ahead to step 11:
336 can be fit into 1480 4 times, resulting in a remainder of 136.
Write down 4 as next digit of the result. 
Result so far: 129678.574
If we subtract 1344 from 1480, we get 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

On to step 12:
If we divide 1360 by 336, we get 4 and a remainder of 16.
Write down 4 as next digit of the result. 
Result so far: 129678.5744
If we subtract 1344 from 1360, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The quotient of the division is 129678.5744, and the remainder is 0.00016.
