80412172 ÷ 844 
Our goal is to divide 80412172 by 844.

Step 1:
When dividing 8 by 844, we get 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Grab the next digit (0) from the dividend, add it to 8, then carry on: 80 / 844

Advancing to step 2:
80 divided by 844 is 0 with a remainder of 80.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 80 to get 80.
Take the next digit (4) from the dividend and append it to 80, then repeat: 804 / 844

Moving on to step 3:
When dividing 804 by 844, we get 0 with a remainder of 804.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 804 after subtracting 0 from 804.
Include the next digit (1) from the dividend after 804, then repeat: 8041 / 844

On to step 4:
844 can be fit into 8041 9 times, resulting in a remainder of 445.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
If we subtract 7596 from 8041, we get 445.
Grab the next digit (2) from the dividend, add it to 445, then carry on: 4452 / 844

Going ahead to step 5:
4452 divided by 844 is 5 with a remainder of 232.
Record the quotient 5 as the next digit in the result. 
Result so far: 95.0
If we take 4220 away from 4452, we end up with 232.
Take the next digit (1) from the dividend and append it to 232, then repeat: 2321 / 844

Let's proceed to step 6:
844 goes into 2321 2 times with a remainder of 633.
The next digit of our result is 2. 
Result so far: 952.0
If we take 1688 away from 2321, we end up with 633.
Include the next digit (7) from the dividend after 633, then repeat: 6337 / 844

Step 7:
844 can be fit into 6337 7 times, resulting in a remainder of 429.
The number 7 becomes the next digit in our result. 
Result so far: 9527.0
Subtract 5908 from 6337 to get 429.
Include the next digit (2) from the dividend after 429, then repeat: 4292 / 844

Let's proceed to step 8:
If we divide 4292 by 844, we get 5 and a remainder of 72.
The next digit of our result is 5. 
Result so far: 95275.0
Subtracting 4220 from 4292 leaves us with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Advancing to step 9:
The number 844 fits into 720 0 times, leaving a remainder of 720.
Use 0 as the next digit of our solution. 
Result so far: 95275.0
The remainder is 720 after subtracting 0 from 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7200, and continue the process.

Moving on to step 10:
The number 844 fits into 7200 8 times, leaving a remainder of 448.
The next digit of our result is 8. 
Result so far: 95275.08
Deduct 6752 from 7200 and we're left with 448.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4480, and continue the process.

On to step 11:
The number 844 fits into 4480 5 times, leaving a remainder of 260.
The number 5 becomes the next digit in our result. 
Result so far: 95275.085
Subtracting 4220 from 4480 leaves us with 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Let's proceed to step 12:
844 can be fit into 2600 3 times, resulting in a remainder of 68.
Put 3 as the next digit of the answer. 
Result so far: 95275.0853
Deduct 2532 from 2600 and we're left with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Let's proceed to step 13:
680 divided by 844 is 0 with a remainder of 680.
Use 0 as the next digit of our solution. 
Result so far: 95275.0853
Subtract 0 from 680 to get 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6800, and continue the process.

Let's proceed to step 14:
6800 divided by 844 is 8 with a remainder of 48.
Put 8 as the next digit of the answer. 
Result so far: 95275.085308
If we take 6752 away from 6800, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Advancing to step 15:
The number 844 fits into 480 0 times, leaving a remainder of 480.
Use 0 as the next digit of our solution. 
Result so far: 95275.085308
The remainder is 480 after subtracting 0 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

On to step 16:
4800 divided by 844 is 5 with a remainder of 580.
The next digit of our result is 5. 
Result so far: 95275.08530805
Deduct 4220 from 4800 and we're left with 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5800, and continue the process.

After the division, we end up with 95275.08530805 and a remainder of 5.8e-07.
