We look at the division of 206209 by 51 
We want to divide 206209 by 51.

Going ahead to step 1:
2 divided by 51 is 0 with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Take the next digit (0) from the dividend and append it to 2, then repeat: 20 / 51

On to step 2:
51 goes into 20 0 times with a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 20, we get 20.
Fetch the next digit (6) from the dividend, attach it to 20 and continue: 206 / 51

Advancing to step 3:
When dividing 206 by 51, we get 4 with a remainder of 2.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Subtract 204 from 206 to get 2.
Bring next digit (2) of the dividend behind the 2 and repeat the process: 22 / 51

Advancing to step 4:
The number 51 fits into 22 0 times, leaving a remainder of 22.
Write down 0 as next digit of the result. 
Result so far: 40.0
Deduct 0 from 22 and we're left with 22.
Append the next digit (0) from the dividend to 22 and continue with: 220 / 51

Advancing to step 5:
220 divided by 51 is 4 with a remainder of 16.
Record the quotient 4 as the next digit in the result. 
Result so far: 404.0
If we subtract 204 from 220, we get 16.
Fetch the next digit (9) from the dividend, attach it to 16 and continue: 169 / 51

On to step 6:
When dividing 169 by 51, we get 3 with a remainder of 16.
The number 3 becomes the next digit in our result. 
Result so far: 4043.0
If we take 153 away from 169, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 7:
160 divided by 51 is 3 with a remainder of 7.
Put 3 as the next digit of the answer. 
Result so far: 4043.3
If we subtract 153 from 160, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Moving on to step 8:
When dividing 70 by 51, we get 1 with a remainder of 19.
Put 1 as the next digit of the answer. 
Result so far: 4043.31
The remainder is 19 after subtracting 51 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Advancing to step 9:
The number 51 fits into 190 3 times, leaving a remainder of 37.
Write down 3 as next digit of the result. 
Result so far: 4043.313
If we take 153 away from 190, we end up with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Step 10:
370 divided by 51 is 7 with a remainder of 13.
Record the quotient 7 as the next digit in the result. 
Result so far: 4043.3137
Subtract 357 from 370 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Going ahead to step 11:
When dividing 130 by 51, we get 2 with a remainder of 28.
The number 2 becomes the next digit in our result. 
Result so far: 4043.31372
If we take 102 away from 130, we end up with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Let's proceed to step 12:
51 can be fit into 280 5 times, resulting in a remainder of 25.
Write down 5 as next digit of the result. 
Result so far: 4043.313725
Subtracting 255 from 280 leaves us with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Advancing to step 13:
The number 51 fits into 250 4 times, leaving a remainder of 46.
Put 4 as the next digit of the answer. 
Result so far: 4043.3137254
The remainder is 46 after subtracting 204 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Going ahead to step 14:
51 can be fit into 460 9 times, resulting in a remainder of 1.
The next digit of our result is 9. 
Result so far: 4043.31372549
Deduct 459 from 460 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

In conclusion, the division gives 4043.31372549 with a balance of 1e-09.
