Let's divide 80215947 by 429
We're looking to find how many times 429 goes into 80215947.

Advancing to step 1:
If we divide 8 by 429, we get 0 and a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Take the next digit (0) from the dividend and append it to 8, then repeat: 80 / 429

Let's proceed to step 2:
80 divided by 429 is 0 with a remainder of 80.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 80, we get 80.
Fetch the next digit (2) from the dividend, attach it to 80 and continue: 802 / 429

Step 3:
802 divided by 429 is 1 with a remainder of 373.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 429 from 802 leaves us with 373.
Fetch the next digit (1) from the dividend, attach it to 373 and continue: 3731 / 429

Moving on to step 4:
3731 divided by 429 is 8 with a remainder of 299.
Write down 8 as next digit of the result. 
Result so far: 18.0
Subtracting 3432 from 3731 leaves us with 299.
Grab the next digit (5) from the dividend, add it to 299, then carry on: 2995 / 429

On to step 5:
429 can be fit into 2995 6 times, resulting in a remainder of 421.
Use 6 as the next digit of our solution. 
Result so far: 186.0
Subtract 2574 from 2995 to get 421.
Take the next digit (9) from the dividend and append it to 421, then repeat: 4219 / 429

Going ahead to step 6:
If we divide 4219 by 429, we get 9 and a remainder of 358.
Write down 9 as next digit of the result. 
Result so far: 1869.0
Deduct 3861 from 4219 and we're left with 358.
Append the next digit (4) from the dividend to 358 and continue with: 3584 / 429

Let's proceed to step 7:
429 goes into 3584 8 times with a remainder of 152.
The number 8 becomes the next digit in our result. 
Result so far: 18698.0
The remainder is 152 after subtracting 3432 from 3584.
Append the next digit (7) from the dividend to 152 and continue with: 1527 / 429

On to step 8:
429 can be fit into 1527 3 times, resulting in a remainder of 240.
The number 3 becomes the next digit in our result. 
Result so far: 186983.0
If we subtract 1287 from 1527, we get 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Moving on to step 9:
When dividing 2400 by 429, we get 5 with a remainder of 255.
Put 5 as the next digit of the answer. 
Result so far: 186983.5
If we subtract 2145 from 2400, we get 255.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2550, and continue the process.

Advancing to step 10:
When dividing 2550 by 429, we get 5 with a remainder of 405.
Use 5 as the next digit of our solution. 
Result so far: 186983.55
If we subtract 2145 from 2550, we get 405.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4050, and continue the process.

The final result is 186983.55 with a remainder of 0.405.
