We look at the division of 35716099 by 663 
Let's see how many times 663 fits into 35716099.

On to step 1:
663 goes into 3 0 times with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Fetch the next digit (5) from the dividend, attach it to 3 and continue: 35 / 663

Step 2:
If we divide 35 by 663, we get 0 and a remainder of 35.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 35 leaves us with 35.
Include the next digit (7) from the dividend after 35, then repeat: 357 / 663

Moving on to step 3:
663 goes into 357 0 times with a remainder of 357.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 357 and we're left with 357.
Include the next digit (1) from the dividend after 357, then repeat: 3571 / 663

Moving on to step 4:
663 can be fit into 3571 5 times, resulting in a remainder of 256.
The next digit of our result is 5. 
Result so far: 5.0
Deduct 3315 from 3571 and we're left with 256.
Fetch the next digit (6) from the dividend, attach it to 256 and continue: 2566 / 663

Let's proceed to step 5:
If we divide 2566 by 663, we get 3 and a remainder of 577.
Record the quotient 3 as the next digit in the result. 
Result so far: 53.0
The remainder is 577 after subtracting 1989 from 2566.
Take the next digit (0) from the dividend and append it to 577, then repeat: 5770 / 663

Step 6:
5770 divided by 663 is 8 with a remainder of 466.
Put 8 as the next digit of the answer. 
Result so far: 538.0
If we take 5304 away from 5770, we end up with 466.
Grab the next digit (9) from the dividend, add it to 466, then carry on: 4669 / 663

Going ahead to step 7:
The number 663 fits into 4669 7 times, leaving a remainder of 28.
The number 7 becomes the next digit in our result. 
Result so far: 5387.0
If we subtract 4641 from 4669, we get 28.
Fetch the next digit (9) from the dividend, attach it to 28 and continue: 289 / 663

On to step 8:
289 divided by 663 is 0 with a remainder of 289.
The next digit of our result is 0. 
Result so far: 53870.0
The remainder is 289 after subtracting 0 from 289.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2890, and continue the process.

Step 9:
2890 divided by 663 is 4 with a remainder of 238.
Use 4 as the next digit of our solution. 
Result so far: 53870.4
Subtracting 2652 from 2890 leaves us with 238.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2380, and continue the process.

Advancing to step 10:
2380 divided by 663 is 3 with a remainder of 391.
Put 3 as the next digit of the answer. 
Result so far: 53870.43
If we subtract 1989 from 2380, we get 391.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3910, and continue the process.

Advancing to step 11:
If we divide 3910 by 663, we get 5 and a remainder of 595.
Record the quotient 5 as the next digit in the result. 
Result so far: 53870.435
If we subtract 3315 from 3910, we get 595.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5950, and continue the process.

Going ahead to step 12:
663 can be fit into 5950 8 times, resulting in a remainder of 646.
The number 8 becomes the next digit in our result. 
Result so far: 53870.4358
Subtract 5304 from 5950 to get 646.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6460, and continue the process.

Step 13:
When dividing 6460 by 663, we get 9 with a remainder of 493.
Write down 9 as next digit of the result. 
Result so far: 53870.43589
Subtract 5967 from 6460 to get 493.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4930, and continue the process.

Let's proceed to step 14:
If we divide 4930 by 663, we get 7 and a remainder of 289.
Use 7 as the next digit of our solution. 
Result so far: 53870.435897
If we take 4641 away from 4930, we end up with 289.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2890, and continue the process.

Step 15:
663 goes into 2890 4 times with a remainder of 238.
Record the quotient 4 as the next digit in the result. 
Result so far: 53870.4358974
Subtracting 2652 from 2890 leaves us with 238.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2380, and continue the process.

Step 16:
If we divide 2380 by 663, we get 3 and a remainder of 391.
The number 3 becomes the next digit in our result. 
Result so far: 53870.43589743
The remainder is 391 after subtracting 1989 from 2380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3910, and continue the process.

The final outcome is 53870.43589743, with a leftover of 3.91e-07.
