97438789 ÷ 450 
We want to figure out the number of times 97438789 can be divided by 450.

Step 1:
When dividing 9 by 450, we get 0 with a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Take the next digit (7) from the dividend and append it to 9, then repeat: 97 / 450

On to step 2:
97 divided by 450 is 0 with a remainder of 97.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 97 leaves us with 97.
Bring next digit (4) of the dividend behind the 97 and repeat the process: 974 / 450

Advancing to step 3:
450 goes into 974 2 times with a remainder of 74.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Deduct 900 from 974 and we're left with 74.
Grab the next digit (3) from the dividend, add it to 74, then carry on: 743 / 450

On to step 4:
450 can be fit into 743 1 times, resulting in a remainder of 293.
The next digit of our result is 1. 
Result so far: 21.0
If we subtract 450 from 743, we get 293.
Append the next digit (8) from the dividend to 293 and continue with: 2938 / 450

Step 5:
When dividing 2938 by 450, we get 6 with a remainder of 238.
The number 6 becomes the next digit in our result. 
Result so far: 216.0
If we subtract 2700 from 2938, we get 238.
Include the next digit (7) from the dividend after 238, then repeat: 2387 / 450

On to step 6:
When dividing 2387 by 450, we get 5 with a remainder of 137.
Use 5 as the next digit of our solution. 
Result so far: 2165.0
Deduct 2250 from 2387 and we're left with 137.
Include the next digit (8) from the dividend after 137, then repeat: 1378 / 450

Let's proceed to step 7:
450 goes into 1378 3 times with a remainder of 28.
Write down 3 as next digit of the result. 
Result so far: 21653.0
Deduct 1350 from 1378 and we're left with 28.
Bring next digit (9) of the dividend behind the 28 and repeat the process: 289 / 450

Let's proceed to step 8:
If we divide 289 by 450, we get 0 and a remainder of 289.
Write down 0 as next digit of the result. 
Result so far: 216530.0
The remainder is 289 after subtracting 0 from 289.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2890, and continue the process.

Step 9:
If we divide 2890 by 450, we get 6 and a remainder of 190.
Put 6 as the next digit of the answer. 
Result so far: 216530.6
If we take 2700 away from 2890, we end up with 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Going ahead to step 10:
If we divide 1900 by 450, we get 4 and a remainder of 100.
Use 4 as the next digit of our solution. 
Result so far: 216530.64
Subtract 1800 from 1900 to get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Let's proceed to step 11:
450 goes into 1000 2 times with a remainder of 100.
The number 2 becomes the next digit in our result. 
Result so far: 216530.642
Subtract 900 from 1000 to get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Advancing to step 12:
450 goes into 1000 2 times with a remainder of 100.
Use 2 as the next digit of our solution. 
Result so far: 216530.6422
The remainder is 100 after subtracting 900 from 1000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

In conclusion, the division gives 216530.6422 with a balance of 0.001.
