We're dividing 99039420 by 903 
Our goal is to divide 99039420 by 903.

Moving on to step 1:
When dividing 9 by 903, we get 0 with a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Grab the next digit (9) from the dividend, add it to 9, then carry on: 99 / 903

On to step 2:
When dividing 99 by 903, we get 0 with a remainder of 99.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 99 leaves us with 99.
Take the next digit (0) from the dividend and append it to 99, then repeat: 990 / 903

On to step 3:
990 divided by 903 is 1 with a remainder of 87.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 903 from 990 to get 87.
Append the next digit (3) from the dividend to 87 and continue with: 873 / 903

Moving on to step 4:
If we divide 873 by 903, we get 0 and a remainder of 873.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
Deduct 0 from 873 and we're left with 873.
Include the next digit (9) from the dividend after 873, then repeat: 8739 / 903

Going ahead to step 5:
903 goes into 8739 9 times with a remainder of 612.
The number 9 becomes the next digit in our result. 
Result so far: 109.0
The remainder is 612 after subtracting 8127 from 8739.
Bring next digit (4) of the dividend behind the 612 and repeat the process: 6124 / 903

Advancing to step 6:
6124 divided by 903 is 6 with a remainder of 706.
Record the quotient 6 as the next digit in the result. 
Result so far: 1096.0
If we take 5418 away from 6124, we end up with 706.
Fetch the next digit (2) from the dividend, attach it to 706 and continue: 7062 / 903

On to step 7:
7062 divided by 903 is 7 with a remainder of 741.
Write down 7 as next digit of the result. 
Result so far: 10967.0
Deduct 6321 from 7062 and we're left with 741.
Include the next digit (0) from the dividend after 741, then repeat: 7410 / 903

Let's proceed to step 8:
When dividing 7410 by 903, we get 8 with a remainder of 186.
The number 8 becomes the next digit in our result. 
Result so far: 109678.0
Subtracting 7224 from 7410 leaves us with 186.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1860, and continue the process.

Step 9:
If we divide 1860 by 903, we get 2 and a remainder of 54.
The next digit of our result is 2. 
Result so far: 109678.2
If we take 1806 away from 1860, we end up with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Let's proceed to step 10:
The number 903 fits into 540 0 times, leaving a remainder of 540.
Use 0 as the next digit of our solution. 
Result so far: 109678.2
Deduct 0 from 540 and we're left with 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5400, and continue the process.

Moving on to step 11:
903 goes into 5400 5 times with a remainder of 885.
Write down 5 as next digit of the result. 
Result so far: 109678.205
Subtracting 4515 from 5400 leaves us with 885.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8850, and continue the process.

Moving on to step 12:
The number 903 fits into 8850 9 times, leaving a remainder of 723.
The number 9 becomes the next digit in our result. 
Result so far: 109678.2059
Subtract 8127 from 8850 to get 723.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7230, and continue the process.

Moving on to step 13:
If we divide 7230 by 903, we get 8 and a remainder of 6.
The next digit of our result is 8. 
Result so far: 109678.20598
The remainder is 6 after subtracting 7224 from 7230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 14:
903 can be fit into 60 0 times, resulting in a remainder of 60.
The number 0 becomes the next digit in our result. 
Result so far: 109678.20598
The remainder is 60 after subtracting 0 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 15:
903 can be fit into 600 0 times, resulting in a remainder of 600.
Record the quotient 0 as the next digit in the result. 
Result so far: 109678.20598
Subtracting 0 from 600 leaves us with 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

The final result is 109678.20598 with a remainder of 6e-06.
