51599276 ÷ 104 
Let's see how many times 104 fits into 51599276.

Step 1:
If we divide 5 by 104, we get 0 and a remainder of 5.
Write down 0 as next digit of 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 / 104

Step 2:
51 divided by 104 is 0 with a remainder of 51.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 51, we end up with 51.
Bring next digit (5) of the dividend behind the 51 and repeat the process: 515 / 104

On to step 3:
If we divide 515 by 104, we get 4 and a remainder of 99.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Deduct 416 from 515 and we're left with 99.
Grab the next digit (9) from the dividend, add it to 99, then carry on: 999 / 104

Advancing to step 4:
If we divide 999 by 104, we get 9 and a remainder of 63.
The next digit of our result is 9. 
Result so far: 49.0
Subtract 936 from 999 to get 63.
Grab the next digit (9) from the dividend, add it to 63, then carry on: 639 / 104

Advancing to step 5:
104 goes into 639 6 times with a remainder of 15.
Write down 6 as next digit of the result. 
Result so far: 496.0
Subtracting 624 from 639 leaves us with 15.
Append the next digit (2) from the dividend to 15 and continue with: 152 / 104

Advancing to step 6:
When dividing 152 by 104, we get 1 with a remainder of 48.
The number 1 becomes the next digit in our result. 
Result so far: 4961.0
Subtract 104 from 152 to get 48.
Fetch the next digit (7) from the dividend, attach it to 48 and continue: 487 / 104

On to step 7:
If we divide 487 by 104, we get 4 and a remainder of 71.
The number 4 becomes the next digit in our result. 
Result so far: 49614.0
Deduct 416 from 487 and we're left with 71.
Grab the next digit (6) from the dividend, add it to 71, then carry on: 716 / 104

On to step 8:
104 can be fit into 716 6 times, resulting in a remainder of 92.
The next digit of our result is 6. 
Result so far: 496146.0
Subtract 624 from 716 to get 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Let's proceed to step 9:
104 can be fit into 920 8 times, resulting in a remainder of 88.
Write down 8 as next digit of the result. 
Result so far: 496146.8
Deduct 832 from 920 and we're left with 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Moving on to step 10:
880 divided by 104 is 8 with a remainder of 48.
The next digit of our result is 8. 
Result so far: 496146.88
Deduct 832 from 880 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Our division results in 496146.88 with a remaining 0.048.
