We look at the division of 26349013 by 521 
Our goal is to divide 26349013 by 521.

Step 1:
521 can be fit into 2 0 times, resulting in a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Fetch the next digit (6) from the dividend, attach it to 2 and continue: 26 / 521

On to step 2:
26 divided by 521 is 0 with a remainder of 26.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 26, we end up with 26.
Append the next digit (3) from the dividend to 26 and continue with: 263 / 521

Let's proceed to step 3:
521 goes into 263 0 times with a remainder of 263.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 263, we end up with 263.
Take the next digit (4) from the dividend and append it to 263, then repeat: 2634 / 521

Step 4:
521 goes into 2634 5 times with a remainder of 29.
Write down 5 as next digit of the result. 
Result so far: 5.0
The remainder is 29 after subtracting 2605 from 2634.
Bring next digit (9) of the dividend behind the 29 and repeat the process: 299 / 521

On to step 5:
The number 521 fits into 299 0 times, leaving a remainder of 299.
The next digit of our result is 0. 
Result so far: 50.0
Deduct 0 from 299 and we're left with 299.
Fetch the next digit (0) from the dividend, attach it to 299 and continue: 2990 / 521

On to step 6:
2990 divided by 521 is 5 with a remainder of 385.
Put 5 as the next digit of the answer. 
Result so far: 505.0
Subtracting 2605 from 2990 leaves us with 385.
Append the next digit (1) from the dividend to 385 and continue with: 3851 / 521

On to step 7:
If we divide 3851 by 521, we get 7 and a remainder of 204.
The number 7 becomes the next digit in our result. 
Result so far: 5057.0
Subtract 3647 from 3851 to get 204.
Bring next digit (3) of the dividend behind the 204 and repeat the process: 2043 / 521

Step 8:
When dividing 2043 by 521, we get 3 with a remainder of 480.
Use 3 as the next digit of our solution. 
Result so far: 50573.0
Deduct 1563 from 2043 and we're left with 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Advancing to step 9:
521 goes into 4800 9 times with a remainder of 111.
The next digit of our result is 9. 
Result so far: 50573.9
The remainder is 111 after subtracting 4689 from 4800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1110, and continue the process.

Let's proceed to step 10:
1110 divided by 521 is 2 with a remainder of 68.
Record the quotient 2 as the next digit in the result. 
Result so far: 50573.92
The remainder is 68 after subtracting 1042 from 1110.
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:
When dividing 680 by 521, we get 1 with a remainder of 159.
Write down 1 as next digit of the result. 
Result so far: 50573.921
The remainder is 159 after subtracting 521 from 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1590, and continue the process.

On to step 12:
521 can be fit into 1590 3 times, resulting in a remainder of 27.
Put 3 as the next digit of the answer. 
Result so far: 50573.9213
If we take 1563 away from 1590, we end up with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Advancing to step 13:
The number 521 fits into 270 0 times, leaving a remainder of 270.
Put 0 as the next digit of the answer. 
Result so far: 50573.9213
If we take 0 away from 270, we end up with 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

Going ahead to step 14:
521 can be fit into 2700 5 times, resulting in a remainder of 95.
Record the quotient 5 as the next digit in the result. 
Result so far: 50573.921305
If we subtract 2605 from 2700, we get 95.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

On to step 15:
When dividing 950 by 521, we get 1 with a remainder of 429.
Use 1 as the next digit of our solution. 
Result so far: 50573.9213051
If we take 521 away from 950, we end up with 429.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4290, and continue the process.

Step 16:
If we divide 4290 by 521, we get 8 and a remainder of 122.
Record the quotient 8 as the next digit in the result. 
Result so far: 50573.92130518
Subtract 4168 from 4290 to get 122.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

The final result is 50573.92130518 with a remainder of 1.22e-07.
