53867703 ÷ 104 
Our goal is to divide 53867703 by 104.

Advancing to step 1:
104 goes into 5 0 times with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Bring next digit (3) of the dividend behind the 5 and repeat the process: 53 / 104

Step 2:
104 can be fit into 53 0 times, resulting in a remainder of 53.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 53, we get 53.
Append the next digit (8) from the dividend to 53 and continue with: 538 / 104

On to step 3:
When dividing 538 by 104, we get 5 with a remainder of 18.
Write down 5 as next digit of the result. 
Result so far: 5.0
If we take 520 away from 538, we end up with 18.
Include the next digit (6) from the dividend after 18, then repeat: 186 / 104

Let's proceed to step 4:
If we divide 186 by 104, we get 1 and a remainder of 82.
The next digit of our result is 1. 
Result so far: 51.0
Subtract 104 from 186 to get 82.
Grab the next digit (7) from the dividend, add it to 82, then carry on: 827 / 104

On to step 5:
The number 104 fits into 827 7 times, leaving a remainder of 99.
Record the quotient 7 as the next digit in the result. 
Result so far: 517.0
The remainder is 99 after subtracting 728 from 827.
Fetch the next digit (7) from the dividend, attach it to 99 and continue: 997 / 104

On to step 6:
104 goes into 997 9 times with a remainder of 61.
Record the quotient 9 as the next digit in the result. 
Result so far: 5179.0
The remainder is 61 after subtracting 936 from 997.
Append the next digit (0) from the dividend to 61 and continue with: 610 / 104

Going ahead to step 7:
When dividing 610 by 104, we get 5 with a remainder of 90.
Record the quotient 5 as the next digit in the result. 
Result so far: 51795.0
Subtract 520 from 610 to get 90.
Fetch the next digit (3) from the dividend, attach it to 90 and continue: 903 / 104

Going ahead to step 8:
When dividing 903 by 104, we get 8 with a remainder of 71.
Put 8 as the next digit of the answer. 
Result so far: 517958.0
Subtract 832 from 903 to get 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Step 9:
If we divide 710 by 104, we get 6 and a remainder of 86.
The next digit of our result is 6. 
Result so far: 517958.6
If we take 624 away from 710, we end up with 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

On to step 10:
104 goes into 860 8 times with a remainder of 28.
The number 8 becomes the next digit in our result. 
Result so far: 517958.68
Deduct 832 from 860 and we're left 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.

Advancing to step 11:
When dividing 280 by 104, we get 2 with a remainder of 72.
The next digit of our result is 2. 
Result so far: 517958.682
If we subtract 208 from 280, we get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Moving on to step 12:
If we divide 720 by 104, we get 6 and a remainder of 96.
Write down 6 as next digit of the result. 
Result so far: 517958.6826
Deduct 624 from 720 and we're left with 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

On to step 13:
960 divided by 104 is 9 with a remainder of 24.
Use 9 as the next digit of our solution. 
Result so far: 517958.68269
Subtract 936 from 960 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 14:
If we divide 240 by 104, we get 2 and a remainder of 32.
Record the quotient 2 as the next digit in the result. 
Result so far: 517958.682692
Subtracting 208 from 240 leaves us 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.

Moving on to step 15:
The number 104 fits into 320 3 times, leaving a remainder of 8.
Record the quotient 3 as the next digit in the result. 
Result so far: 517958.6826923
If we take 312 away from 320, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 16:
The number 104 fits into 80 0 times, leaving a remainder of 80.
Record the quotient 0 as the next digit in the result. 
Result so far: 517958.6826923
Subtracting 0 from 80 leaves us with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

After the division, we end up with 517958.6826923 and a remainder of 8e-08.
