We're dividing 81099710 by 807 
Let's see how many times 807 fits into 81099710.

Let's proceed to step 1:
When dividing 8 by 807, we get 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Take the next digit (1) from the dividend and append it to 8, then repeat: 81 / 807

Moving on to step 2:
81 divided by 807 is 0 with a remainder of 81.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 81 leaves us with 81.
Fetch the next digit (0) from the dividend, attach it to 81 and continue: 810 / 807

Advancing to step 3:
The number 807 fits into 810 1 times, leaving a remainder of 3.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 807 from 810, we get 3.
Grab the next digit (9) from the dividend, add it to 3, then carry on: 39 / 807

Step 4:
When dividing 39 by 807, we get 0 with a remainder of 39.
Write down 0 as next digit of the result. 
Result so far: 10.0
If we take 0 away from 39, we end up with 39.
Bring next digit (9) of the dividend behind the 39 and repeat the process: 399 / 807

On to step 5:
399 divided by 807 is 0 with a remainder of 399.
Record the quotient 0 as the next digit in the result. 
Result so far: 100.0
If we subtract 0 from 399, we get 399.
Take the next digit (7) from the dividend and append it to 399, then repeat: 3997 / 807

On to step 6:
If we divide 3997 by 807, we get 4 and a remainder of 769.
Record the quotient 4 as the next digit in the result. 
Result so far: 1004.0
If we subtract 3228 from 3997, we get 769.
Append the next digit (1) from the dividend to 769 and continue with: 7691 / 807

On to step 7:
7691 divided by 807 is 9 with a remainder of 428.
The next digit of our result is 9. 
Result so far: 10049.0
The remainder is 428 after subtracting 7263 from 7691.
Grab the next digit (0) from the dividend, add it to 428, then carry on: 4280 / 807

Let's proceed to step 8:
If we divide 4280 by 807, we get 5 and a remainder of 245.
The next digit of our result is 5. 
Result so far: 100495.0
Subtract 4035 from 4280 to get 245.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2450, and continue the process.

Moving on to step 9:
The number 807 fits into 2450 3 times, leaving a remainder of 29.
The next digit of our result is 3. 
Result so far: 100495.3
Deduct 2421 from 2450 and we're left with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Going ahead to step 10:
290 divided by 807 is 0 with a remainder of 290.
Put 0 as the next digit of the answer. 
Result so far: 100495.3
Deduct 0 from 290 and we're left with 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

Let's proceed to step 11:
807 can be fit into 2900 3 times, resulting in a remainder of 479.
Use 3 as the next digit of our solution. 
Result so far: 100495.303
If we take 2421 away from 2900, we end up with 479.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4790, and continue the process.

On to step 12:
807 can be fit into 4790 5 times, resulting in a remainder of 755.
The number 5 becomes the next digit in our result. 
Result so far: 100495.3035
Subtracting 4035 from 4790 leaves us with 755.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7550, and continue the process.

Moving on to step 13:
The number 807 fits into 7550 9 times, leaving a remainder of 287.
Record the quotient 9 as the next digit in the result. 
Result so far: 100495.30359
If we take 7263 away from 7550, we end up with 287.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2870, and continue the process.

Step 14:
807 can be fit into 2870 3 times, resulting in a remainder of 449.
Put 3 as the next digit of the answer. 
Result so far: 100495.303593
If we take 2421 away from 2870, we end up with 449.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4490, and continue the process.

Let's proceed to step 15:
The number 807 fits into 4490 5 times, leaving a remainder of 455.
The next digit of our result is 5. 
Result so far: 100495.3035935
If we take 4035 away from 4490, we end up with 455.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4550, and continue the process.

Step 16:
The number 807 fits into 4550 5 times, leaving a remainder of 515.
Use 5 as the next digit of our solution. 
Result so far: 100495.30359355
If we subtract 4035 from 4550, we get 515.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5150, and continue the process.

After the division, we end up with 100495.30359355 and a remainder of 5.15e-07.
