21008242 ÷ 891 
Our goal is to divide 21008242 by 891.

Advancing to step 1:
891 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
Subtracting 0 from 2 leaves us with 2.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 891

Advancing to step 2:
21 divided by 891 is 0 with a remainder of 21.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 21 and we're left with 21.
Fetch the next digit (0) from the dividend, attach it to 21 and continue: 210 / 891

Going ahead to step 3:
891 can be fit into 210 0 times, resulting in a remainder of 210.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 210 leaves us with 210.
Bring next digit (0) of the dividend behind the 210 and repeat the process: 2100 / 891

Going ahead to step 4:
2100 divided by 891 is 2 with a remainder of 318.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we take 1782 away from 2100, we end up with 318.
Bring next digit (8) of the dividend behind the 318 and repeat the process: 3188 / 891

Moving on to step 5:
891 goes into 3188 3 times with a remainder of 515.
Put 3 as the next digit of the answer. 
Result so far: 23.0
Subtracting 2673 from 3188 leaves us with 515.
Append the next digit (2) from the dividend to 515 and continue with: 5152 / 891

On to step 6:
891 can be fit into 5152 5 times, resulting in a remainder of 697.
Write down 5 as next digit of the result. 
Result so far: 235.0
Subtracting 4455 from 5152 leaves us with 697.
Fetch the next digit (4) from the dividend, attach it to 697 and continue: 6974 / 891

Going ahead to step 7:
6974 divided by 891 is 7 with a remainder of 737.
Put 7 as the next digit of the answer. 
Result so far: 2357.0
If we subtract 6237 from 6974, we get 737.
Include the next digit (2) from the dividend after 737, then repeat: 7372 / 891

Step 8:
The number 891 fits into 7372 8 times, leaving a remainder of 244.
Use 8 as the next digit of our solution. 
Result so far: 23578.0
Subtract 7128 from 7372 to get 244.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2440, and continue the process.

Advancing to step 9:
891 can be fit into 2440 2 times, resulting in a remainder of 658.
Put 2 as the next digit of the answer. 
Result so far: 23578.2
If we subtract 1782 from 2440, we get 658.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6580, and continue the process.

On to step 10:
6580 divided by 891 is 7 with a remainder of 343.
Record the quotient 7 as the next digit in the result. 
Result so far: 23578.27
Subtracting 6237 from 6580 leaves us with 343.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3430, and continue the process.

Going ahead to step 11:
When dividing 3430 by 891, we get 3 with a remainder of 757.
The next digit of our result is 3. 
Result so far: 23578.273
Deduct 2673 from 3430 and we're left with 757.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7570, and continue the process.

Moving on to step 12:
891 goes into 7570 8 times with a remainder of 442.
Record the quotient 8 as the next digit in the result. 
Result so far: 23578.2738
Deduct 7128 from 7570 and we're left with 442.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4420, and continue the process.

Going ahead to step 13:
891 goes into 4420 4 times with a remainder of 856.
Record the quotient 4 as the next digit in the result. 
Result so far: 23578.27384
Subtract 3564 from 4420 to get 856.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8560, and continue the process.

Advancing to step 14:
891 goes into 8560 9 times with a remainder of 541.
Record the quotient 9 as the next digit in the result. 
Result so far: 23578.273849
If we take 8019 away from 8560, we end up with 541.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5410, and continue the process.

Moving on to step 15:
The number 891 fits into 5410 6 times, leaving a remainder of 64.
Put 6 as the next digit of the answer. 
Result so far: 23578.2738496
If we take 5346 away from 5410, we end up with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Going ahead to step 16:
640 divided by 891 is 0 with a remainder of 640.
The number 0 becomes the next digit in our result. 
Result so far: 23578.2738496
If we subtract 0 from 640, we get 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

Our division results in 23578.2738496 with a remaining 6.4e-07.
