21057316 ÷ 887 
We're looking to find how many times 887 goes into 21057316.

Let's proceed to step 1:
When dividing 2 by 887, 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.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 887

Let's proceed to step 2:
887 goes into 21 0 times with a remainder of 21.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 21 to get 21.
Append the next digit (0) from the dividend to 21 and continue with: 210 / 887

Advancing to step 3:
887 goes into 210 0 times with a remainder of 210.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 210 leaves us with 210.
Take the next digit (5) from the dividend and append it to 210, then repeat: 2105 / 887

Advancing to step 4:
887 goes into 2105 2 times with a remainder of 331.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtract 1774 from 2105 to get 331.
Include the next digit (7) from the dividend after 331, then repeat: 3317 / 887

Moving on to step 5:
3317 divided by 887 is 3 with a remainder of 656.
The next digit of our result is 3. 
Result so far: 23.0
If we take 2661 away from 3317, we end up with 656.
Bring next digit (3) of the dividend behind the 656 and repeat the process: 6563 / 887

Going ahead to step 6:
When dividing 6563 by 887, we get 7 with a remainder of 354.
Use 7 as the next digit of our solution. 
Result so far: 237.0
Subtracting 6209 from 6563 leaves us with 354.
Bring next digit (1) of the dividend behind the 354 and repeat the process: 3541 / 887

Going ahead to step 7:
The number 887 fits into 3541 3 times, leaving a remainder of 880.
Write down 3 as next digit of the result. 
Result so far: 2373.0
Subtract 2661 from 3541 to get 880.
Fetch the next digit (6) from the dividend, attach it to 880 and continue: 8806 / 887

Step 8:
The number 887 fits into 8806 9 times, leaving a remainder of 823.
Put 9 as the next digit of the answer. 
Result so far: 23739.0
Subtract 7983 from 8806 to get 823.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8230, and continue the process.

Advancing to step 9:
8230 divided by 887 is 9 with a remainder of 247.
The next digit of our result is 9. 
Result so far: 23739.9
Deduct 7983 from 8230 and we're left with 247.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2470, and continue the process.

Step 10:
887 goes into 2470 2 times with a remainder of 696.
Use 2 as the next digit of our solution. 
Result so far: 23739.92
The remainder is 696 after subtracting 1774 from 2470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6960, and continue the process.

Let's proceed to step 11:
The number 887 fits into 6960 7 times, leaving a remainder of 751.
Use 7 as the next digit of our solution. 
Result so far: 23739.927
Subtract 6209 from 6960 to get 751.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7510, and continue the process.

On to step 12:
If we divide 7510 by 887, we get 8 and a remainder of 414.
Record the quotient 8 as the next digit in the result. 
Result so far: 23739.9278
The remainder is 414 after subtracting 7096 from 7510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4140, and continue the process.

Step 13:
887 goes into 4140 4 times with a remainder of 592.
Use 4 as the next digit of our solution. 
Result so far: 23739.92784
Subtract 3548 from 4140 to get 592.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5920, and continue the process.

Let's proceed to step 14:
The number 887 fits into 5920 6 times, leaving a remainder of 598.
Use 6 as the next digit of our solution. 
Result so far: 23739.927846
Subtract 5322 from 5920 to get 598.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5980, and continue the process.

Moving on to step 15:
If we divide 5980 by 887, we get 6 and a remainder of 658.
Record the quotient 6 as the next digit in the result. 
Result so far: 23739.9278466
Deduct 5322 from 5980 and we're left with 658.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6580, and continue the process.

The final result is 23739.9278466 with a remainder of 6.58e-06.
