We look at the division of 9406890 by 450 
We want to figure out the number of times 9406890 can be divided by 450.

Let's proceed to step 1:
When dividing 9 by 450, we get 0 with a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Bring next digit (4) of the dividend behind the 9 and repeat the process: 94 / 450

Step 2:
450 goes into 94 0 times with a remainder of 94.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 94, we get 94.
Grab the next digit (0) from the dividend, add it to 94, then carry on: 940 / 450

Let's proceed to step 3:
450 goes into 940 2 times with a remainder of 40.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtracting 900 from 940 leaves us with 40.
Append the next digit (6) from the dividend to 40 and continue with: 406 / 450

Let's proceed to step 4:
450 goes into 406 0 times with a remainder of 406.
The next digit of our result is 0. 
Result so far: 20.0
Subtracting 0 from 406 leaves us with 406.
Take the next digit (8) from the dividend and append it to 406, then repeat: 4068 / 450

Let's proceed to step 5:
450 can be fit into 4068 9 times, resulting in a remainder of 18.
Put 9 as the next digit of the answer. 
Result so far: 209.0
If we take 4050 away from 4068, we end up with 18.
Grab the next digit (9) from the dividend, add it to 18, then carry on: 189 / 450

Let's proceed to step 6:
189 divided by 450 is 0 with a remainder of 189.
The number 0 becomes the next digit in our result. 
Result so far: 2090.0
If we take 0 away from 189, we end up with 189.
Include the next digit (0) from the dividend after 189, then repeat: 1890 / 450

Moving on to step 7:
450 can be fit into 1890 4 times, resulting in a remainder of 90.
Use 4 as the next digit of our solution. 
Result so far: 20904.0
Deduct 1800 from 1890 and we're left with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Going ahead to step 8:
900 divided by 450 is 2 with a remainder of 0.
Record the quotient 2 as the next digit in the result. 
Result so far: 20904.2
Subtract 900 from 900 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 9:
If we divide 0 by 450, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 20904.2
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 10:
450 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 20904.2
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The quotient of the division is 20904.2, and the remainder is 0.0.
