We're dividing 42432420 by 200 
We want to divide 42432420 by 200.

Step 1:
200 can be fit into 4 0 times, resulting in a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Include the next digit (2) from the dividend after 4, then repeat: 42 / 200

Going ahead to step 2:
The number 200 fits into 42 0 times, leaving a remainder of 42.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 42 and we're left with 42.
Take the next digit (4) from the dividend and append it to 42, then repeat: 424 / 200

Going ahead to step 3:
If we divide 424 by 200, we get 2 and a remainder of 24.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Deduct 400 from 424 and we're left with 24.
Fetch the next digit (3) from the dividend, attach it to 24 and continue: 243 / 200

Step 4:
243 divided by 200 is 1 with a remainder of 43.
The number 1 becomes the next digit in our result. 
Result so far: 21.0
The remainder is 43 after subtracting 200 from 243.
Grab the next digit (2) from the dividend, add it to 43, then carry on: 432 / 200

Moving on to step 5:
When dividing 432 by 200, we get 2 with a remainder of 32.
Use 2 as the next digit of our solution. 
Result so far: 212.0
If we subtract 400 from 432, we get 32.
Bring next digit (4) of the dividend behind the 32 and repeat the process: 324 / 200

Step 6:
200 can be fit into 324 1 times, resulting in a remainder of 124.
Use 1 as the next digit of our solution. 
Result so far: 2121.0
If we subtract 200 from 324, we get 124.
Bring next digit (2) of the dividend behind the 124 and repeat the process: 1242 / 200

Step 7:
If we divide 1242 by 200, we get 6 and a remainder of 42.
Use 6 as the next digit of our solution. 
Result so far: 21216.0
Subtracting 1200 from 1242 leaves us with 42.
Bring next digit (0) of the dividend behind the 42 and repeat the process: 420 / 200

Going ahead to step 8:
If we divide 420 by 200, we get 2 and a remainder of 20.
Use 2 as the next digit of our solution. 
Result so far: 212162.0
If we take 400 away from 420, we end up 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.

On to step 9:
200 divided by 200 is 1 with a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 212162.1
Subtract 200 from 200 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 10:
0 divided by 200 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 212162.1
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 11:
0 divided by 200 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 212162.1
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 212162.1 with a remaining 0.0.
