15664172 ÷ 450 
Our goal is to divide 15664172 by 450.

Advancing to step 1:
If we divide 1 by 450, we get 0 and a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Append the next digit (5) from the dividend to 1 and continue with: 15 / 450

Going ahead to step 2:
15 divided by 450 is 0 with a remainder of 15.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 15, we end up with 15.
Include the next digit (6) from the dividend after 15, then repeat: 156 / 450

Step 3:
450 can be fit into 156 0 times, resulting in a remainder of 156.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 156, we get 156.
Bring next digit (6) of the dividend behind the 156 and repeat the process: 1566 / 450

Step 4:
When dividing 1566 by 450, we get 3 with a remainder of 216.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
If we take 1350 away from 1566, we end up with 216.
Grab the next digit (4) from the dividend, add it to 216, then carry on: 2164 / 450

On to step 5:
450 can be fit into 2164 4 times, resulting in a remainder of 364.
Use 4 as the next digit of our solution. 
Result so far: 34.0
If we subtract 1800 from 2164, we get 364.
Take the next digit (1) from the dividend and append it to 364, then repeat: 3641 / 450

Let's proceed to step 6:
450 can be fit into 3641 8 times, resulting in a remainder of 41.
Put 8 as the next digit of the answer. 
Result so far: 348.0
The remainder is 41 after subtracting 3600 from 3641.
Fetch the next digit (7) from the dividend, attach it to 41 and continue: 417 / 450

On to step 7:
If we divide 417 by 450, we get 0 and a remainder of 417.
The number 0 becomes the next digit in our result. 
Result so far: 3480.0
Subtract 0 from 417 to get 417.
Grab the next digit (2) from the dividend, add it to 417, then carry on: 4172 / 450

Going ahead to step 8:
450 goes into 4172 9 times with a remainder of 122.
Record the quotient 9 as the next digit in the result. 
Result so far: 34809.0
If we take 4050 away from 4172, we end up with 122.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

Advancing to step 9:
When dividing 1220 by 450, we get 2 with a remainder of 320.
The number 2 becomes the next digit in our result. 
Result so far: 34809.2
Deduct 900 from 1220 and we're left with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Moving on to step 10:
If we divide 3200 by 450, we get 7 and a remainder of 50.
Record the quotient 7 as the next digit in the result. 
Result so far: 34809.27
If we take 3150 away from 3200, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 11:
500 divided by 450 is 1 with a remainder of 50.
Record the quotient 1 as the next digit in the result. 
Result so far: 34809.271
The remainder is 50 after subtracting 450 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 12:
If we divide 500 by 450, we get 1 and a remainder of 50.
The number 1 becomes the next digit in our result. 
Result so far: 34809.2711
Subtract 450 from 500 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

In conclusion, the division gives 34809.2711 with a balance of 0.0005.
