Let's divide 21603043 by 881
Let's see how many times 881 fits into 21603043.

On to step 1:
881 can be fit into 2 0 times, resulting in a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 881

Going ahead to step 2:
881 can be fit into 21 0 times, resulting in a remainder of 21.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 21 to get 21.
Grab the next digit (6) from the dividend, add it to 21, then carry on: 216 / 881

Let's proceed to step 3:
When dividing 216 by 881, we get 0 with a remainder of 216.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 216 leaves us with 216.
Bring next digit (0) of the dividend behind the 216 and repeat the process: 2160 / 881

Step 4:
If we divide 2160 by 881, we get 2 and a remainder of 398.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Deduct 1762 from 2160 and we're left with 398.
Append the next digit (3) from the dividend to 398 and continue with: 3983 / 881

On to step 5:
When dividing 3983 by 881, we get 4 with a remainder of 459.
Write down 4 as next digit of the result. 
Result so far: 24.0
If we subtract 3524 from 3983, we get 459.
Bring next digit (0) of the dividend behind the 459 and repeat the process: 4590 / 881

Moving on to step 6:
When dividing 4590 by 881, we get 5 with a remainder of 185.
Write down 5 as next digit of the result. 
Result so far: 245.0
If we take 4405 away from 4590, we end up with 185.
Grab the next digit (4) from the dividend, add it to 185, then carry on: 1854 / 881

Moving on to step 7:
881 can be fit into 1854 2 times, resulting in a remainder of 92.
The next digit of our result is 2. 
Result so far: 2452.0
Deduct 1762 from 1854 and we're left with 92.
Grab the next digit (3) from the dividend, add it to 92, then carry on: 923 / 881

Step 8:
When dividing 923 by 881, we get 1 with a remainder of 42.
The number 1 becomes the next digit in our result. 
Result so far: 24521.0
If we take 881 away from 923, we end up with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Moving on to step 9:
If we divide 420 by 881, we get 0 and a remainder of 420.
The number 0 becomes the next digit in our result. 
Result so far: 24521.0
Subtract 0 from 420 to get 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

On to step 10:
The number 881 fits into 4200 4 times, leaving a remainder of 676.
Record the quotient 4 as the next digit in the result. 
Result so far: 24521.04
Deduct 3524 from 4200 and we're left with 676.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6760, and continue the process.

On to step 11:
881 can be fit into 6760 7 times, resulting in a remainder of 593.
The number 7 becomes the next digit in our result. 
Result so far: 24521.047
Subtracting 6167 from 6760 leaves us with 593.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5930, and continue the process.

On to step 12:
5930 divided by 881 is 6 with a remainder of 644.
Put 6 as the next digit of the answer. 
Result so far: 24521.0476
The remainder is 644 after subtracting 5286 from 5930.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6440, and continue the process.

Step 13:
The number 881 fits into 6440 7 times, leaving a remainder of 273.
The number 7 becomes the next digit in our result. 
Result so far: 24521.04767
If we subtract 6167 from 6440, we get 273.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2730, and continue the process.

Moving on to step 14:
When dividing 2730 by 881, we get 3 with a remainder of 87.
The number 3 becomes the next digit in our result. 
Result so far: 24521.047673
The remainder is 87 after subtracting 2643 from 2730.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

Moving on to step 15:
870 divided by 881 is 0 with a remainder of 870.
Write down 0 as next digit of the result. 
Result so far: 24521.047673
If we subtract 0 from 870, we get 870.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8700, and continue the process.

Going ahead to step 16:
If we divide 8700 by 881, we get 9 and a remainder of 771.
Use 9 as the next digit of our solution. 
Result so far: 24521.04767309
If we subtract 7929 from 8700, we get 771.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7710, and continue the process.

The final outcome is 24521.04767309, with a leftover of 7.71e-07.
