We look at the division of 51389798 by 209 
We want to divide 51389798 by 209.

Advancing to step 1:
The number 209 fits into 5 0 times, leaving a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Include the next digit (1) from the dividend after 5, then repeat: 51 / 209

Moving on to step 2:
51 divided by 209 is 0 with a remainder of 51.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 51 after subtracting 0 from 51.
Bring next digit (3) of the dividend behind the 51 and repeat the process: 513 / 209

Moving on to step 3:
When dividing 513 by 209, we get 2 with a remainder of 95.
The next digit of our result is 2. 
Result so far: 2.0
If we subtract 418 from 513, we get 95.
Append the next digit (8) from the dividend to 95 and continue with: 958 / 209

Step 4:
If we divide 958 by 209, we get 4 and a remainder of 122.
Put 4 as the next digit of the answer. 
Result so far: 24.0
The remainder is 122 after subtracting 836 from 958.
Include the next digit (9) from the dividend after 122, then repeat: 1229 / 209

Moving on to step 5:
209 can be fit into 1229 5 times, resulting in a remainder of 184.
The next digit of our result is 5. 
Result so far: 245.0
If we subtract 1045 from 1229, we get 184.
Include the next digit (7) from the dividend after 184, then repeat: 1847 / 209

Going ahead to step 6:
209 goes into 1847 8 times with a remainder of 175.
The next digit of our result is 8. 
Result so far: 2458.0
The remainder is 175 after subtracting 1672 from 1847.
Include the next digit (9) from the dividend after 175, then repeat: 1759 / 209

On to step 7:
When dividing 1759 by 209, we get 8 with a remainder of 87.
The number 8 becomes the next digit in our result. 
Result so far: 24588.0
If we take 1672 away from 1759, we end up with 87.
Append the next digit (8) from the dividend to 87 and continue with: 878 / 209

Step 8:
When dividing 878 by 209, we get 4 with a remainder of 42.
The number 4 becomes the next digit in our result. 
Result so far: 245884.0
Deduct 836 from 878 and we're left with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Step 9:
The number 209 fits into 420 2 times, leaving a remainder of 2.
The number 2 becomes the next digit in our result. 
Result so far: 245884.2
If we subtract 418 from 420, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 10:
When dividing 20 by 209, we get 0 with a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 245884.2
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 11:
209 goes into 200 0 times with a remainder of 200.
Record the quotient 0 as the next digit in the result. 
Result so far: 245884.2
If we subtract 0 from 200, we get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

The quotient of the division is 245884.2, and the remainder is 0.02.
