We're dividing 42216639 by 209 
Let's see how many times 209 fits into 42216639.

On to step 1:
If we divide 4 by 209, we get 0 and a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Take the next digit (2) from the dividend and append it to 4, then repeat: 42 / 209

Step 2:
209 goes into 42 0 times with a remainder of 42.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 42, we get 42.
Bring next digit (2) of the dividend behind the 42 and repeat the process: 422 / 209

Going ahead to step 3:
209 goes into 422 2 times with a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 2.0
Deduct 418 from 422 and we're left with 4.
Append the next digit (1) from the dividend to 4 and continue with: 41 / 209

On to step 4:
209 can be fit into 41 0 times, resulting in a remainder of 41.
Write down 0 as next digit of the result. 
Result so far: 20.0
Subtracting 0 from 41 leaves us with 41.
Grab the next digit (6) from the dividend, add it to 41, then carry on: 416 / 209

Let's proceed to step 5:
When dividing 416 by 209, we get 1 with a remainder of 207.
Record the quotient 1 as the next digit in the result. 
Result so far: 201.0
Subtract 209 from 416 to get 207.
Bring next digit (6) of the dividend behind the 207 and repeat the process: 2076 / 209

Moving on to step 6:
The number 209 fits into 2076 9 times, leaving a remainder of 195.
Use 9 as the next digit of our solution. 
Result so far: 2019.0
If we take 1881 away from 2076, we end up with 195.
Append the next digit (3) from the dividend to 195 and continue with: 1953 / 209

On to step 7:
209 can be fit into 1953 9 times, resulting in a remainder of 72.
Use 9 as the next digit of our solution. 
Result so far: 20199.0
If we take 1881 away from 1953, we end up with 72.
Take the next digit (9) from the dividend and append it to 72, then repeat: 729 / 209

Moving on to step 8:
When dividing 729 by 209, we get 3 with a remainder of 102.
The next digit of our result is 3. 
Result so far: 201993.0
The remainder is 102 after subtracting 627 from 729.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

Let's proceed to step 9:
If we divide 1020 by 209, we get 4 and a remainder of 184.
Record the quotient 4 as the next digit in the result. 
Result so far: 201993.4
Deduct 836 from 1020 and we're left with 184.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

Going ahead to step 10:
209 goes into 1840 8 times with a remainder of 168.
Put 8 as the next digit of the answer. 
Result so far: 201993.48
Deduct 1672 from 1840 and we're left with 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

Advancing to step 11:
1680 divided by 209 is 8 with a remainder of 8.
The next digit of our result is 8. 
Result so far: 201993.488
Deduct 1672 from 1680 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The final result is 201993.488 with a remainder of 0.0008.
