We look at the division of 42031288 by 209 
Our goal is to divide 42031288 by 209.

Let's proceed to step 1:
When dividing 4 by 209, we get 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.
Append the next digit (2) from the dividend to 4 and continue with: 42 / 209

Let's proceed to step 2:
If we divide 42 by 209, we get 0 and a remainder of 42.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 42 and we're left with 42.
Take the next digit (0) from the dividend and append it to 42, then repeat: 420 / 209

Step 3:
209 can be fit into 420 2 times, resulting in a remainder of 2.
The next digit of our result is 2. 
Result so far: 2.0
If we subtract 418 from 420, we get 2.
Fetch the next digit (3) from the dividend, attach it to 2 and continue: 23 / 209

Let's proceed to step 4:
The number 209 fits into 23 0 times, leaving a remainder of 23.
Record the quotient 0 as the next digit in the result. 
Result so far: 20.0
Subtracting 0 from 23 leaves us with 23.
Fetch the next digit (1) from the dividend, attach it to 23 and continue: 231 / 209

Advancing to step 5:
231 divided by 209 is 1 with a remainder of 22.
Write down 1 as next digit of the result. 
Result so far: 201.0
If we subtract 209 from 231, we get 22.
Take the next digit (2) from the dividend and append it to 22, then repeat: 222 / 209

Advancing to step 6:
The number 209 fits into 222 1 times, leaving a remainder of 13.
Put 1 as the next digit of the answer. 
Result so far: 2011.0
The remainder is 13 after subtracting 209 from 222.
Fetch the next digit (8) from the dividend, attach it to 13 and continue: 138 / 209

Step 7:
The number 209 fits into 138 0 times, leaving a remainder of 138.
Write down 0 as next digit of the result. 
Result so far: 20110.0
The remainder is 138 after subtracting 0 from 138.
Take the next digit (8) from the dividend and append it to 138, then repeat: 1388 / 209

Advancing to step 8:
209 can be fit into 1388 6 times, resulting in a remainder of 134.
Record the quotient 6 as the next digit in the result. 
Result so far: 201106.0
Subtract 1254 from 1388 to get 134.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1340, and continue the process.

Let's proceed to step 9:
209 goes into 1340 6 times with a remainder of 86.
Record the quotient 6 as the next digit in the result. 
Result so far: 201106.6
Deduct 1254 from 1340 and we're left with 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Step 10:
860 divided by 209 is 4 with a remainder of 24.
Record the quotient 4 as the next digit in the result. 
Result so far: 201106.64
If we take 836 away from 860, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 11:
240 divided by 209 is 1 with a remainder of 31.
Write down 1 as next digit of the result. 
Result so far: 201106.641
The remainder is 31 after subtracting 209 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Step 12:
If we divide 310 by 209, we get 1 and a remainder of 101.
The number 1 becomes the next digit in our result. 
Result so far: 201106.6411
The remainder is 101 after subtracting 209 from 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1010, and continue the process.

In conclusion, the division gives 201106.6411 with a balance of 0.00101.
