80504608 ÷ 430 
Our goal is to divide 80504608 by 430.

Let's proceed to step 1:
The number 430 fits into 8 0 times, leaving a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Append the next digit (0) from the dividend to 8 and continue with: 80 / 430

Going ahead to step 2:
80 divided by 430 is 0 with a remainder of 80.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 80, we get 80.
Bring next digit (5) of the dividend behind the 80 and repeat the process: 805 / 430

On to step 3:
430 can be fit into 805 1 times, resulting in a remainder of 375.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 430 from 805, we get 375.
Take the next digit (0) from the dividend and append it to 375, then repeat: 3750 / 430

Advancing to step 4:
If we divide 3750 by 430, we get 8 and a remainder of 310.
Record the quotient 8 as the next digit in the result. 
Result so far: 18.0
If we subtract 3440 from 3750, we get 310.
Grab the next digit (4) from the dividend, add it to 310, then carry on: 3104 / 430

Going ahead to step 5:
430 can be fit into 3104 7 times, resulting in a remainder of 94.
Use 7 as the next digit of our solution. 
Result so far: 187.0
Deduct 3010 from 3104 and we're left with 94.
Append the next digit (6) from the dividend to 94 and continue with: 946 / 430

Let's proceed to step 6:
The number 430 fits into 946 2 times, leaving a remainder of 86.
Write down 2 as next digit of the result. 
Result so far: 1872.0
Deduct 860 from 946 and we're left with 86.
Include the next digit (0) from the dividend after 86, then repeat: 860 / 430

Going ahead to step 7:
When dividing 860 by 430, we get 2 with a remainder of 0.
Record the quotient 2 as the next digit in the result. 
Result so far: 18722.0
Subtract 860 from 860 to get 0.
Grab the next digit (8) from the dividend, add it to 0, then carry on: 8 / 430

Step 8:
430 can be fit into 8 0 times, resulting in a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 187220.0
Subtracting 0 from 8 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 9:
430 can be fit into 80 0 times, resulting in a remainder of 80.
The next digit of our result is 0. 
Result so far: 187220.0
If we take 0 away from 80, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

On to step 10:
800 divided by 430 is 1 with a remainder of 370.
Use 1 as the next digit of our solution. 
Result so far: 187220.01
Subtracting 430 from 800 leaves us with 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3700, and continue the process.

Let's proceed to step 11:
If we divide 3700 by 430, we get 8 and a remainder of 260.
Use 8 as the next digit of our solution. 
Result so far: 187220.018
If we subtract 3440 from 3700, we get 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Advancing to step 12:
When dividing 2600 by 430, we get 6 with a remainder of 20.
The number 6 becomes the next digit in our result. 
Result so far: 187220.0186
If we subtract 2580 from 2600, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 13:
430 can be fit into 200 0 times, resulting in a remainder of 200.
Record the quotient 0 as the next digit in the result. 
Result so far: 187220.0186
Deduct 0 from 200 and we're left with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Let's proceed to step 14:
2000 divided by 430 is 4 with a remainder of 280.
The next digit of our result is 4. 
Result so far: 187220.018604
The remainder is 280 after subtracting 1720 from 2000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Advancing to step 15:
The number 430 fits into 2800 6 times, leaving a remainder of 220.
The next digit of our result is 6. 
Result so far: 187220.0186046
If we subtract 2580 from 2800, we get 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

On to step 16:
The number 430 fits into 2200 5 times, leaving a remainder of 50.
Put 5 as the next digit of the answer. 
Result so far: 187220.01860465
Deduct 2150 from 2200 and we're left 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.

In conclusion, the division gives 187220.01860465 with a balance of 5e-08.
