81297036 ÷ 805 
We're looking to find how many times 805 goes into 81297036.

Advancing to step 1:
805 goes into 8 0 times with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Fetch the next digit (1) from the dividend, attach it to 8 and continue: 81 / 805

Moving on to step 2:
805 can be fit into 81 0 times, resulting in a remainder of 81.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 81 and we're left with 81.
Bring next digit (2) of the dividend behind the 81 and repeat the process: 812 / 805

Advancing to step 3:
805 goes into 812 1 times with a remainder of 7.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 805 from 812 to get 7.
Fetch the next digit (9) from the dividend, attach it to 7 and continue: 79 / 805

Going ahead to step 4:
805 can be fit into 79 0 times, resulting in a remainder of 79.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
If we subtract 0 from 79, we get 79.
Include the next digit (7) from the dividend after 79, then repeat: 797 / 805

Advancing to step 5:
805 can be fit into 797 0 times, resulting in a remainder of 797.
Record the quotient 0 as the next digit in the result. 
Result so far: 100.0
If we take 0 away from 797, we end up with 797.
Append the next digit (0) from the dividend to 797 and continue with: 7970 / 805

Going ahead to step 6:
When dividing 7970 by 805, we get 9 with a remainder of 725.
Put 9 as the next digit of the answer. 
Result so far: 1009.0
The remainder is 725 after subtracting 7245 from 7970.
Take the next digit (3) from the dividend and append it to 725, then repeat: 7253 / 805

Advancing to step 7:
7253 divided by 805 is 9 with a remainder of 8.
Use 9 as the next digit of our solution. 
Result so far: 10099.0
Subtracting 7245 from 7253 leaves us with 8.
Fetch the next digit (6) from the dividend, attach it to 8 and continue: 86 / 805

Advancing to step 8:
If we divide 86 by 805, we get 0 and a remainder of 86.
Write down 0 as next digit of the result. 
Result so far: 100990.0
The remainder is 86 after subtracting 0 from 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

On to step 9:
The number 805 fits into 860 1 times, leaving a remainder of 55.
The number 1 becomes the next digit in our result. 
Result so far: 100990.1
The remainder is 55 after subtracting 805 from 860.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Step 10:
When dividing 550 by 805, we get 0 with a remainder of 550.
Record the quotient 0 as the next digit in the result. 
Result so far: 100990.1
Subtract 0 from 550 to get 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5500, and continue the process.

Advancing to step 11:
If we divide 5500 by 805, we get 6 and a remainder of 670.
Put 6 as the next digit of the answer. 
Result so far: 100990.106
Subtracting 4830 from 5500 leaves us with 670.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6700, and continue the process.

Going ahead to step 12:
If we divide 6700 by 805, we get 8 and a remainder of 260.
Put 8 as the next digit of the answer. 
Result so far: 100990.1068
Subtract 6440 from 6700 to 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.

On to step 13:
805 goes into 2600 3 times with a remainder of 185.
The number 3 becomes the next digit in our result. 
Result so far: 100990.10683
If we subtract 2415 from 2600, we get 185.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1850, and continue the process.

Advancing to step 14:
The number 805 fits into 1850 2 times, leaving a remainder of 240.
Record the quotient 2 as the next digit in the result. 
Result so far: 100990.106832
Subtracting 1610 from 1850 leaves us with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

On to step 15:
805 can be fit into 2400 2 times, resulting in a remainder of 790.
The next digit of our result is 2. 
Result so far: 100990.1068322
If we subtract 1610 from 2400, we get 790.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7900, and continue the process.

Our division results in 100990.1068322 with a remaining 7.9e-06.
