We look at the division of 21040930 by 891 
Let's see how many times 891 fits into 21040930.

Advancing to step 1:
2 divided by 891 is 0 with a remainder of 2.
The next digit of our result is 0. 
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 / 891

Step 2:
If we divide 21 by 891, we get 0 and a remainder of 21.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 21, we end up with 21.
Include the next digit (0) from the dividend after 21, then repeat: 210 / 891

Advancing to step 3:
When dividing 210 by 891, we get 0 with a remainder of 210.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 210 to get 210.
Take the next digit (4) from the dividend and append it to 210, then repeat: 2104 / 891

Let's proceed to step 4:
891 can be fit into 2104 2 times, resulting in a remainder of 322.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtract 1782 from 2104 to get 322.
Grab the next digit (0) from the dividend, add it to 322, then carry on: 3220 / 891

Going ahead to step 5:
891 can be fit into 3220 3 times, resulting in a remainder of 547.
Write down 3 as next digit of the result. 
Result so far: 23.0
Deduct 2673 from 3220 and we're left with 547.
Bring next digit (9) of the dividend behind the 547 and repeat the process: 5479 / 891

Moving on to step 6:
When dividing 5479 by 891, we get 6 with a remainder of 133.
Write down 6 as next digit of the result. 
Result so far: 236.0
Deduct 5346 from 5479 and we're left with 133.
Fetch the next digit (3) from the dividend, attach it to 133 and continue: 1333 / 891

Moving on to step 7:
When dividing 1333 by 891, we get 1 with a remainder of 442.
Use 1 as the next digit of our solution. 
Result so far: 2361.0
The remainder is 442 after subtracting 891 from 1333.
Append the next digit (0) from the dividend to 442 and continue with: 4420 / 891

Moving on to step 8:
When dividing 4420 by 891, we get 4 with a remainder of 856.
The next digit of our result is 4. 
Result so far: 23614.0
If we take 3564 away from 4420, we end up with 856.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8560, and continue the process.

Step 9:
891 goes into 8560 9 times with a remainder of 541.
The next digit of our result is 9. 
Result so far: 23614.9
Deduct 8019 from 8560 and we're left 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.

Going ahead to step 10:
The number 891 fits into 5410 6 times, leaving a remainder of 64.
Use 6 as the next digit of our solution. 
Result so far: 23614.96
The remainder is 64 after subtracting 5346 from 5410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Step 11:
When dividing 640 by 891, we get 0 with a remainder of 640.
The number 0 becomes the next digit in our result. 
Result so far: 23614.96
Subtracting 0 from 640 leaves us with 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

On to step 12:
891 goes into 6400 7 times with a remainder of 163.
Record the quotient 7 as the next digit in the result. 
Result so far: 23614.9607
Subtract 6237 from 6400 to get 163.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1630, and continue the process.

Step 13:
If we divide 1630 by 891, we get 1 and a remainder of 739.
Write down 1 as next digit of the result. 
Result so far: 23614.96071
Subtract 891 from 1630 to get 739.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7390, and continue the process.

Let's proceed to step 14:
When dividing 7390 by 891, we get 8 with a remainder of 262.
Put 8 as the next digit of the answer. 
Result so far: 23614.960718
If we take 7128 away from 7390, we end up with 262.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2620, and continue the process.

Let's proceed to step 15:
The number 891 fits into 2620 2 times, leaving a remainder of 838.
Use 2 as the next digit of our solution. 
Result so far: 23614.9607182
If we take 1782 away from 2620, we end up with 838.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8380, and continue the process.

Let's proceed to step 16:
891 goes into 8380 9 times with a remainder of 361.
The next digit of our result is 9. 
Result so far: 23614.96071829
The remainder is 361 after subtracting 8019 from 8380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3610, and continue the process.

The quotient of the division is 23614.96071829, and the remainder is 3.61e-07.
