53129033 ÷ 104 
We want to divide 53129033 by 104.

Let's proceed to step 1:
104 goes into 5 0 times with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Take the next digit (3) from the dividend and append it to 5, then repeat: 53 / 104

Going ahead to step 2:
The number 104 fits into 53 0 times, leaving a remainder of 53.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 53, we get 53.
Fetch the next digit (1) from the dividend, attach it to 53 and continue: 531 / 104

Step 3:
104 can be fit into 531 5 times, resulting in a remainder of 11.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
Deduct 520 from 531 and we're left with 11.
Grab the next digit (2) from the dividend, add it to 11, then carry on: 112 / 104

Moving on to step 4:
112 divided by 104 is 1 with a remainder of 8.
The next digit of our result is 1. 
Result so far: 51.0
The remainder is 8 after subtracting 104 from 112.
Append the next digit (9) from the dividend to 8 and continue with: 89 / 104

Going ahead to step 5:
When dividing 89 by 104, we get 0 with a remainder of 89.
Write down 0 as next digit of the result. 
Result so far: 510.0
If we take 0 away from 89, we end up with 89.
Take the next digit (0) from the dividend and append it to 89, then repeat: 890 / 104

Let's proceed to step 6:
The number 104 fits into 890 8 times, leaving a remainder of 58.
The next digit of our result is 8. 
Result so far: 5108.0
If we subtract 832 from 890, we get 58.
Take the next digit (3) from the dividend and append it to 58, then repeat: 583 / 104

Going ahead to step 7:
When dividing 583 by 104, we get 5 with a remainder of 63.
The number 5 becomes the next digit in our result. 
Result so far: 51085.0
If we take 520 away from 583, we end up with 63.
Take the next digit (3) from the dividend and append it to 63, then repeat: 633 / 104

Going ahead to step 8:
104 goes into 633 6 times with a remainder of 9.
Write down 6 as next digit of the result. 
Result so far: 510856.0
If we subtract 624 from 633, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 9:
90 divided by 104 is 0 with a remainder of 90.
Write down 0 as next digit of the result. 
Result so far: 510856.0
If we take 0 away from 90, we end up with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Step 10:
When dividing 900 by 104, we get 8 with a remainder of 68.
Write down 8 as next digit of the result. 
Result so far: 510856.08
Deduct 832 from 900 and we're left with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Step 11:
104 can be fit into 680 6 times, resulting in a remainder of 56.
The number 6 becomes the next digit in our result. 
Result so far: 510856.086
Subtract 624 from 680 to get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Let's proceed to step 12:
When dividing 560 by 104, we get 5 with a remainder of 40.
Record the quotient 5 as the next digit in the result. 
Result so far: 510856.0865
If we subtract 520 from 560, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 13:
104 goes into 400 3 times with a remainder of 88.
Write down 3 as next digit of the result. 
Result so far: 510856.08653
If we subtract 312 from 400, we get 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Advancing to step 14:
The number 104 fits into 880 8 times, leaving a remainder of 48.
The next digit of our result is 8. 
Result so far: 510856.086538
The remainder is 48 after subtracting 832 from 880.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Moving on to step 15:
480 divided by 104 is 4 with a remainder of 64.
Put 4 as the next digit of the answer. 
Result so far: 510856.0865384
Deduct 416 from 480 and we're left with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Let's proceed to step 16:
When dividing 640 by 104, we get 6 with a remainder of 16.
Use 6 as the next digit of our solution. 
Result so far: 510856.08653846
Deduct 624 from 640 and we're left 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.

Our division results in 510856.08653846 with a remaining 1.6e-08.
