We look at the division of 25355539 by 528 
We want to divide 25355539 by 528.

Step 1:
When dividing 2 by 528, we get 0 with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Fetch the next digit (5) from the dividend, attach it to 2 and continue: 25 / 528

Advancing to step 2:
The number 528 fits into 25 0 times, leaving a remainder of 25.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 25 and we're left with 25.
Take the next digit (3) from the dividend and append it to 25, then repeat: 253 / 528

Advancing to step 3:
528 goes into 253 0 times with a remainder of 253.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 253, we end up with 253.
Bring next digit (5) of the dividend behind the 253 and repeat the process: 2535 / 528

Step 4:
528 goes into 2535 4 times with a remainder of 423.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Deduct 2112 from 2535 and we're left with 423.
Include the next digit (5) from the dividend after 423, then repeat: 4235 / 528

Advancing to step 5:
The number 528 fits into 4235 8 times, leaving a remainder of 11.
The number 8 becomes the next digit in our result. 
Result so far: 48.0
If we subtract 4224 from 4235, we get 11.
Include the next digit (5) from the dividend after 11, then repeat: 115 / 528

On to step 6:
The number 528 fits into 115 0 times, leaving a remainder of 115.
Put 0 as the next digit of the answer. 
Result so far: 480.0
If we take 0 away from 115, we end up with 115.
Grab the next digit (3) from the dividend, add it to 115, then carry on: 1153 / 528

Step 7:
528 goes into 1153 2 times with a remainder of 97.
Use 2 as the next digit of our solution. 
Result so far: 4802.0
Subtracting 1056 from 1153 leaves us with 97.
Take the next digit (9) from the dividend and append it to 97, then repeat: 979 / 528

Moving on to step 8:
If we divide 979 by 528, we get 1 and a remainder of 451.
Record the quotient 1 as the next digit in the result. 
Result so far: 48021.0
Subtract 528 from 979 to get 451.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4510, and continue the process.

Advancing to step 9:
If we divide 4510 by 528, we get 8 and a remainder of 286.
Put 8 as the next digit of the answer. 
Result so far: 48021.8
If we subtract 4224 from 4510, we get 286.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2860, and continue the process.

Moving on to step 10:
If we divide 2860 by 528, we get 5 and a remainder of 220.
Write down 5 as next digit of the result. 
Result so far: 48021.85
If we take 2640 away from 2860, we end up with 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Going ahead to step 11:
The number 528 fits into 2200 4 times, leaving a remainder of 88.
Put 4 as the next digit of the answer. 
Result so far: 48021.854
If we subtract 2112 from 2200, 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.

Going ahead to step 12:
The number 528 fits into 880 1 times, leaving a remainder of 352.
The next digit of our result is 1. 
Result so far: 48021.8541
Subtract 528 from 880 to get 352.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

Moving on to step 13:
528 can be fit into 3520 6 times, resulting in a remainder of 352.
Put 6 as the next digit of the answer. 
Result so far: 48021.85416
If we take 3168 away from 3520, we end up with 352.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

Moving on to step 14:
When dividing 3520 by 528, we get 6 with a remainder of 352.
Put 6 as the next digit of the answer. 
Result so far: 48021.854166
Subtracting 3168 from 3520 leaves us with 352.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

The final result is 48021.854166 with a remainder of 3.52e-05.
