We divide 51809 by 98
We want to divide 51809 by 98.

On to step 1:
When dividing 5 by 98, we get 0 with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Bring next digit (1) of the dividend behind the 5 and repeat the process: 51 / 98

Advancing to step 2:
The number 98 fits into 51 0 times, leaving a remainder of 51.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 51 leaves us with 51.
Fetch the next digit (8) from the dividend, attach it to 51 and continue: 518 / 98

Advancing to step 3:
98 goes into 518 5 times with a remainder of 28.
The next digit of our result is 5. 
Result so far: 5.0
Subtract 490 from 518 to get 28.
Bring next digit (0) of the dividend behind the 28 and repeat the process: 280 / 98

Going ahead to step 4:
If we divide 280 by 98, we get 2 and a remainder of 84.
Use 2 as the next digit of our solution. 
Result so far: 52.0
Subtract 196 from 280 to get 84.
Include the next digit (9) from the dividend after 84, then repeat: 849 / 98

Step 5:
98 goes into 849 8 times with a remainder of 65.
Record the quotient 8 as the next digit in the result. 
Result so far: 528.0
Deduct 784 from 849 and we're left with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Step 6:
98 goes into 650 6 times with a remainder of 62.
Record the quotient 6 as the next digit in the result. 
Result so far: 528.6
Subtracting 588 from 650 leaves us with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Let's proceed to step 7:
If we divide 620 by 98, we get 6 and a remainder of 32.
Write down 6 as next digit of the result. 
Result so far: 528.66
If we take 588 away from 620, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Our division results in 528.66 with a remaining 0.032.
