We divide 21331581 by 873
We want to figure out the number of times 21331581 can be divided by 873.

Advancing to step 1:
873 goes into 2 0 times with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 873

Advancing to step 2:
873 goes into 21 0 times with a remainder of 21.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 21 and we're left with 21.
Include the next digit (3) from the dividend after 21, then repeat: 213 / 873

On to step 3:
213 divided by 873 is 0 with a remainder of 213.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 213 to get 213.
Grab the next digit (3) from the dividend, add it to 213, then carry on: 2133 / 873

Let's proceed to step 4:
When dividing 2133 by 873, we get 2 with a remainder of 387.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we take 1746 away from 2133, we end up with 387.
Grab the next digit (1) from the dividend, add it to 387, then carry on: 3871 / 873

Let's proceed to step 5:
873 goes into 3871 4 times with a remainder of 379.
The number 4 becomes the next digit in our result. 
Result so far: 24.0
The remainder is 379 after subtracting 3492 from 3871.
Grab the next digit (5) from the dividend, add it to 379, then carry on: 3795 / 873

Let's proceed to step 6:
When dividing 3795 by 873, we get 4 with a remainder of 303.
Record the quotient 4 as the next digit in the result. 
Result so far: 244.0
Subtracting 3492 from 3795 leaves us with 303.
Take the next digit (8) from the dividend and append it to 303, then repeat: 3038 / 873

Let's proceed to step 7:
The number 873 fits into 3038 3 times, leaving a remainder of 419.
Write down 3 as next digit of the result. 
Result so far: 2443.0
Deduct 2619 from 3038 and we're left with 419.
Append the next digit (1) from the dividend to 419 and continue with: 4191 / 873

On to step 8:
873 goes into 4191 4 times with a remainder of 699.
Put 4 as the next digit of the answer. 
Result so far: 24434.0
Subtract 3492 from 4191 to get 699.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6990, and continue the process.

Let's proceed to step 9:
The number 873 fits into 6990 8 times, leaving a remainder of 6.
Write down 8 as next digit of the result. 
Result so far: 24434.8
Deduct 6984 from 6990 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 10:
873 can be fit into 60 0 times, resulting in a remainder of 60.
Record the quotient 0 as the next digit in the result. 
Result so far: 24434.8
Deduct 0 from 60 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 11:
600 divided by 873 is 0 with a remainder of 600.
Put 0 as the next digit of the answer. 
Result so far: 24434.8
The remainder is 600 after subtracting 0 from 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 24434.8 with a remainder of 0.06.
