We look at the division of 35002521 by 663 
Our goal is to divide 35002521 by 663.

Moving on to step 1:
663 goes into 3 0 times with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Include the next digit (5) from the dividend after 3, then repeat: 35 / 663

Going ahead to step 2:
663 can be fit into 35 0 times, resulting in a remainder of 35.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 35, we end up with 35.
Take the next digit (0) from the dividend and append it to 35, then repeat: 350 / 663

Advancing to step 3:
663 can be fit into 350 0 times, resulting in a remainder of 350.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 350 leaves us with 350.
Take the next digit (0) from the dividend and append it to 350, then repeat: 3500 / 663

Moving on to step 4:
663 can be fit into 3500 5 times, resulting in a remainder of 185.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
Deduct 3315 from 3500 and we're left with 185.
Bring next digit (2) of the dividend behind the 185 and repeat the process: 1852 / 663

Moving on to step 5:
663 can be fit into 1852 2 times, resulting in a remainder of 526.
The number 2 becomes the next digit in our result. 
Result so far: 52.0
Subtracting 1326 from 1852 leaves us with 526.
Take the next digit (5) from the dividend and append it to 526, then repeat: 5265 / 663

Advancing to step 6:
When dividing 5265 by 663, we get 7 with a remainder of 624.
Use 7 as the next digit of our solution. 
Result so far: 527.0
Subtract 4641 from 5265 to get 624.
Fetch the next digit (2) from the dividend, attach it to 624 and continue: 6242 / 663

On to step 7:
6242 divided by 663 is 9 with a remainder of 275.
The next digit of our result is 9. 
Result so far: 5279.0
Subtracting 5967 from 6242 leaves us with 275.
Take the next digit (1) from the dividend and append it to 275, then repeat: 2751 / 663

Moving on to step 8:
When dividing 2751 by 663, we get 4 with a remainder of 99.
Write down 4 as next digit of the result. 
Result so far: 52794.0
If we subtract 2652 from 2751, we get 99.
Since there are no more digits in the dividend, we add a zero to the remainder making it 990, and continue the process.

Moving on to step 9:
663 goes into 990 1 times with a remainder of 327.
Write down 1 as next digit of the result. 
Result so far: 52794.1
Subtracting 663 from 990 leaves us with 327.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3270, and continue the process.

Going ahead to step 10:
663 can be fit into 3270 4 times, resulting in a remainder of 618.
Write down 4 as next digit of the result. 
Result so far: 52794.14
If we take 2652 away from 3270, we end up with 618.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6180, and continue the process.

On to step 11:
663 goes into 6180 9 times with a remainder of 213.
The number 9 becomes the next digit in our result. 
Result so far: 52794.149
Deduct 5967 from 6180 and we're left with 213.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2130, and continue the process.

Moving on to step 12:
When dividing 2130 by 663, we get 3 with a remainder of 141.
The number 3 becomes the next digit in our result. 
Result so far: 52794.1493
Subtracting 1989 from 2130 leaves us with 141.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1410, and continue the process.

Going ahead to step 13:
If we divide 1410 by 663, we get 2 and a remainder of 84.
Put 2 as the next digit of the answer. 
Result so far: 52794.14932
Subtracting 1326 from 1410 leaves us with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

On to step 14:
840 divided by 663 is 1 with a remainder of 177.
Record the quotient 1 as the next digit in the result. 
Result so far: 52794.149321
The remainder is 177 after subtracting 663 from 840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1770, and continue the process.

Advancing to step 15:
The number 663 fits into 1770 2 times, leaving a remainder of 444.
Write down 2 as next digit of the result. 
Result so far: 52794.1493212
Deduct 1326 from 1770 and we're left with 444.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4440, and continue the process.

Going ahead to step 16:
The number 663 fits into 4440 6 times, leaving a remainder of 462.
The number 6 becomes the next digit in our result. 
Result so far: 52794.14932126
If we take 3978 away from 4440, we end up with 462.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4620, and continue the process.

The final outcome is 52794.14932126, with a leftover of 4.62e-07.
