21939709 divided by 873 
We're looking to find how many times 873 goes into 21939709.

Step 1:
873 goes into 2 0 times with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 873

Moving on to step 2:
21 divided by 873 is 0 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.
Take the next digit (9) from the dividend and append it to 21, then repeat: 219 / 873

Advancing to step 3:
If we divide 219 by 873, we get 0 and a remainder of 219.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 219 to get 219.
Take the next digit (3) from the dividend and append it to 219, then repeat: 2193 / 873

Let's proceed to step 4:
873 goes into 2193 2 times with a remainder of 447.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtract 1746 from 2193 to get 447.
Take the next digit (9) from the dividend and append it to 447, then repeat: 4479 / 873

Moving on to step 5:
4479 divided by 873 is 5 with a remainder of 114.
Use 5 as the next digit of our solution. 
Result so far: 25.0
Subtracting 4365 from 4479 leaves us with 114.
Fetch the next digit (7) from the dividend, attach it to 114 and continue: 1147 / 873

Advancing to step 6:
873 goes into 1147 1 times with a remainder of 274.
Put 1 as the next digit of the answer. 
Result so far: 251.0
If we subtract 873 from 1147, we get 274.
Take the next digit (0) from the dividend and append it to 274, then repeat: 2740 / 873

Moving on to step 7:
2740 divided by 873 is 3 with a remainder of 121.
Use 3 as the next digit of our solution. 
Result so far: 2513.0
If we take 2619 away from 2740, we end up with 121.
Append the next digit (9) from the dividend to 121 and continue with: 1219 / 873

Moving on to step 8:
1219 divided by 873 is 1 with a remainder of 346.
Write down 1 as next digit of the result. 
Result so far: 25131.0
Deduct 873 from 1219 and we're left with 346.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3460, and continue the process.

Let's proceed to step 9:
The number 873 fits into 3460 3 times, leaving a remainder of 841.
Write down 3 as next digit of the result. 
Result so far: 25131.3
Subtracting 2619 from 3460 leaves us with 841.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8410, and continue the process.

Going ahead to step 10:
The number 873 fits into 8410 9 times, leaving a remainder of 553.
The next digit of our result is 9. 
Result so far: 25131.39
Deduct 7857 from 8410 and we're left with 553.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5530, and continue the process.

On to step 11:
When dividing 5530 by 873, we get 6 with a remainder of 292.
Write down 6 as next digit of the result. 
Result so far: 25131.396
If we take 5238 away from 5530, we end up with 292.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2920, and continue the process.

Step 12:
If we divide 2920 by 873, we get 3 and a remainder of 301.
Record the quotient 3 as the next digit in the result. 
Result so far: 25131.3963
Deduct 2619 from 2920 and we're left with 301.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3010, and continue the process.

Advancing to step 13:
873 goes into 3010 3 times with a remainder of 391.
Use 3 as the next digit of our solution. 
Result so far: 25131.39633
Subtract 2619 from 3010 to get 391.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3910, and continue the process.

The final outcome is 25131.39633, with a leftover of 0.000391.
