We look at the division of 20089010 by 921 
We're looking to find how many times 921 goes into 20089010.

Let's proceed to step 1:
921 can be fit into 2 0 times, resulting in a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Fetch the next digit (0) from the dividend, attach it to 2 and continue: 20 / 921

Going ahead to step 2:
When dividing 20 by 921, we get 0 with a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 20, we get 20.
Fetch the next digit (0) from the dividend, attach it to 20 and continue: 200 / 921

Advancing to step 3:
200 divided by 921 is 0 with a remainder of 200.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 200 leaves us with 200.
Include the next digit (8) from the dividend after 200, then repeat: 2008 / 921

Going ahead to step 4:
2008 divided by 921 is 2 with a remainder of 166.
Put 2 as the next digit of the answer. 
Result so far: 2.0
The remainder is 166 after subtracting 1842 from 2008.
Append the next digit (9) from the dividend to 166 and continue with: 1669 / 921

Step 5:
921 can be fit into 1669 1 times, resulting in a remainder of 748.
Write down 1 as next digit of the result. 
Result so far: 21.0
Subtracting 921 from 1669 leaves us with 748.
Fetch the next digit (0) from the dividend, attach it to 748 and continue: 7480 / 921

Let's proceed to step 6:
When dividing 7480 by 921, we get 8 with a remainder of 112.
Record the quotient 8 as the next digit in the result. 
Result so far: 218.0
If we subtract 7368 from 7480, we get 112.
Take the next digit (1) from the dividend and append it to 112, then repeat: 1121 / 921

Advancing to step 7:
If we divide 1121 by 921, we get 1 and a remainder of 200.
Put 1 as the next digit of the answer. 
Result so far: 2181.0
The remainder is 200 after subtracting 921 from 1121.
Take the next digit (0) from the dividend and append it to 200, then repeat: 2000 / 921

Going ahead to step 8:
2000 divided by 921 is 2 with a remainder of 158.
The next digit of our result is 2. 
Result so far: 21812.0
If we take 1842 away from 2000, we end up with 158.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1580, and continue the process.

Step 9:
When dividing 1580 by 921, we get 1 with a remainder of 659.
Write down 1 as next digit of the result. 
Result so far: 21812.1
Subtracting 921 from 1580 leaves us with 659.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6590, and continue the process.

Let's proceed to step 10:
When dividing 6590 by 921, we get 7 with a remainder of 143.
The next digit of our result is 7. 
Result so far: 21812.17
Subtract 6447 from 6590 to get 143.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1430, and continue the process.

Moving on to step 11:
921 goes into 1430 1 times with a remainder of 509.
The number 1 becomes the next digit in our result. 
Result so far: 21812.171
Subtracting 921 from 1430 leaves us with 509.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5090, and continue the process.

Step 12:
When dividing 5090 by 921, we get 5 with a remainder of 485.
The next digit of our result is 5. 
Result so far: 21812.1715
The remainder is 485 after subtracting 4605 from 5090.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4850, and continue the process.

Advancing to step 13:
4850 divided by 921 is 5 with a remainder of 245.
Put 5 as the next digit of the answer. 
Result so far: 21812.17155
Subtract 4605 from 4850 to get 245.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2450, and continue the process.

The final result is 21812.17155 with a remainder of 0.000245.
