We look at the division of 90300803 by 886 
We want to figure out the number of times 90300803 can be divided by 886.

Going ahead to step 1:
886 can be fit into 9 0 times, resulting in a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Grab the next digit (0) from the dividend, add it to 9, then carry on: 90 / 886

Advancing to step 2:
The number 886 fits into 90 0 times, leaving a remainder of 90.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 90 leaves us with 90.
Append the next digit (3) from the dividend to 90 and continue with: 903 / 886

Step 3:
The number 886 fits into 903 1 times, leaving a remainder of 17.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 886 from 903 leaves us with 17.
Append the next digit (0) from the dividend to 17 and continue with: 170 / 886

Going ahead to step 4:
When dividing 170 by 886, we get 0 with a remainder of 170.
Use 0 as the next digit of our solution. 
Result so far: 10.0
If we take 0 away from 170, we end up with 170.
Take the next digit (0) from the dividend and append it to 170, then repeat: 1700 / 886

On to step 5:
The number 886 fits into 1700 1 times, leaving a remainder of 814.
Record the quotient 1 as the next digit in the result. 
Result so far: 101.0
Subtracting 886 from 1700 leaves us with 814.
Append the next digit (8) from the dividend to 814 and continue with: 8148 / 886

On to step 6:
When dividing 8148 by 886, we get 9 with a remainder of 174.
Record the quotient 9 as the next digit in the result. 
Result so far: 1019.0
Subtracting 7974 from 8148 leaves us with 174.
Fetch the next digit (0) from the dividend, attach it to 174 and continue: 1740 / 886

Moving on to step 7:
The number 886 fits into 1740 1 times, leaving a remainder of 854.
The next digit of our result is 1. 
Result so far: 10191.0
The remainder is 854 after subtracting 886 from 1740.
Take the next digit (3) from the dividend and append it to 854, then repeat: 8543 / 886

Moving on to step 8:
8543 divided by 886 is 9 with a remainder of 569.
The number 9 becomes the next digit in our result. 
Result so far: 101919.0
Subtract 7974 from 8543 to get 569.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5690, and continue the process.

Let's proceed to step 9:
If we divide 5690 by 886, we get 6 and a remainder of 374.
Record the quotient 6 as the next digit in the result. 
Result so far: 101919.6
If we take 5316 away from 5690, we end up with 374.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3740, and continue the process.

Moving on to step 10:
3740 divided by 886 is 4 with a remainder of 196.
Write down 4 as next digit of the result. 
Result so far: 101919.64
Deduct 3544 from 3740 and we're left with 196.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1960, and continue the process.

Step 11:
If we divide 1960 by 886, we get 2 and a remainder of 188.
Record the quotient 2 as the next digit in the result. 
Result so far: 101919.642
Subtract 1772 from 1960 to get 188.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1880, and continue the process.

Step 12:
If we divide 1880 by 886, we get 2 and a remainder of 108.
Write down 2 as next digit of the result. 
Result so far: 101919.6422
Subtract 1772 from 1880 to get 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

After the division, we end up with 101919.6422 and a remainder of 0.00108.
