21188977 divided by 903 
We want to divide 21188977 by 903.

Advancing to step 1:
When dividing 2 by 903, we get 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 903

Going ahead to step 2:
When dividing 21 by 903, we get 0 with a remainder of 21.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 21 to get 21.
Append the next digit (1) from the dividend to 21 and continue with: 211 / 903

Advancing to step 3:
903 goes into 211 0 times with a remainder of 211.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 211 to get 211.
Append the next digit (8) from the dividend to 211 and continue with: 2118 / 903

Advancing to step 4:
When dividing 2118 by 903, we get 2 with a remainder of 312.
Write down 2 as next digit of the result. 
Result so far: 2.0
The remainder is 312 after subtracting 1806 from 2118.
Grab the next digit (8) from the dividend, add it to 312, then carry on: 3128 / 903

Let's proceed to step 5:
3128 divided by 903 is 3 with a remainder of 419.
Use 3 as the next digit of our solution. 
Result so far: 23.0
Deduct 2709 from 3128 and we're left with 419.
Fetch the next digit (9) from the dividend, attach it to 419 and continue: 4199 / 903

Going ahead to step 6:
903 goes into 4199 4 times with a remainder of 587.
The number 4 becomes the next digit in our result. 
Result so far: 234.0
If we take 3612 away from 4199, we end up with 587.
Take the next digit (7) from the dividend and append it to 587, then repeat: 5877 / 903

Advancing to step 7:
If we divide 5877 by 903, we get 6 and a remainder of 459.
Put 6 as the next digit of the answer. 
Result so far: 2346.0
If we subtract 5418 from 5877, we get 459.
Grab the next digit (7) from the dividend, add it to 459, then carry on: 4597 / 903

On to step 8:
If we divide 4597 by 903, we get 5 and a remainder of 82.
Record the quotient 5 as the next digit in the result. 
Result so far: 23465.0
If we take 4515 away from 4597, we end up with 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Step 9:
903 can be fit into 820 0 times, resulting in a remainder of 820.
The number 0 becomes the next digit in our result. 
Result so far: 23465.0
If we take 0 away from 820, we end up with 820.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8200, and continue the process.

Moving on to step 10:
903 can be fit into 8200 9 times, resulting in a remainder of 73.
Write down 9 as next digit of the result. 
Result so far: 23465.09
Deduct 8127 from 8200 and we're left with 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Moving on to step 11:
903 can be fit into 730 0 times, resulting in a remainder of 730.
Put 0 as the next digit of the answer. 
Result so far: 23465.09
The remainder is 730 after subtracting 0 from 730.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7300, and continue the process.

Moving on to step 12:
The number 903 fits into 7300 8 times, leaving a remainder of 76.
Record the quotient 8 as the next digit in the result. 
Result so far: 23465.0908
Subtract 7224 from 7300 to get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Let's proceed to step 13:
When dividing 760 by 903, we get 0 with a remainder of 760.
The next digit of our result is 0. 
Result so far: 23465.0908
If we subtract 0 from 760, we get 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7600, and continue the process.

Let's proceed to step 14:
When dividing 7600 by 903, we get 8 with a remainder of 376.
The number 8 becomes the next digit in our result. 
Result so far: 23465.090808
Subtract 7224 from 7600 to get 376.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3760, and continue the process.

Advancing to step 15:
3760 divided by 903 is 4 with a remainder of 148.
Put 4 as the next digit of the answer. 
Result so far: 23465.0908084
The remainder is 148 after subtracting 3612 from 3760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

Step 16:
903 can be fit into 1480 1 times, resulting in a remainder of 577.
Use 1 as the next digit of our solution. 
Result so far: 23465.09080841
If we take 903 away from 1480, we end up with 577.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5770, and continue the process.

The final result is 23465.09080841 with a remainder of 5.77e-07.
