We're dividing 86945520 by 807 
Our goal is to divide 86945520 by 807.

On to step 1:
8 divided by 807 is 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Fetch the next digit (6) from the dividend, attach it to 8 and continue: 86 / 807

On to step 2:
807 can be fit into 86 0 times, resulting in a remainder of 86.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 86 leaves us with 86.
Fetch the next digit (9) from the dividend, attach it to 86 and continue: 869 / 807

Let's proceed to step 3:
807 can be fit into 869 1 times, resulting in a remainder of 62.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 807 away from 869, we end up with 62.
Bring next digit (4) of the dividend behind the 62 and repeat the process: 624 / 807

Advancing to step 4:
When dividing 624 by 807, we get 0 with a remainder of 624.
The next digit of our result is 0. 
Result so far: 10.0
If we subtract 0 from 624, we get 624.
Append the next digit (5) from the dividend to 624 and continue with: 6245 / 807

Step 5:
6245 divided by 807 is 7 with a remainder of 596.
Record the quotient 7 as the next digit in the result. 
Result so far: 107.0
The remainder is 596 after subtracting 5649 from 6245.
Take the next digit (5) from the dividend and append it to 596, then repeat: 5965 / 807

Going ahead to step 6:
When dividing 5965 by 807, we get 7 with a remainder of 316.
The next digit of our result is 7. 
Result so far: 1077.0
Deduct 5649 from 5965 and we're left with 316.
Include the next digit (2) from the dividend after 316, then repeat: 3162 / 807

Moving on to step 7:
807 goes into 3162 3 times with a remainder of 741.
Write down 3 as next digit of the result. 
Result so far: 10773.0
Subtracting 2421 from 3162 leaves us with 741.
Append the next digit (0) from the dividend to 741 and continue with: 7410 / 807

On to step 8:
If we divide 7410 by 807, we get 9 and a remainder of 147.
The next digit of our result is 9. 
Result so far: 107739.0
If we subtract 7263 from 7410, we get 147.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1470, and continue the process.

Step 9:
The number 807 fits into 1470 1 times, leaving a remainder of 663.
Put 1 as the next digit of the answer. 
Result so far: 107739.1
The remainder is 663 after subtracting 807 from 1470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6630, and continue the process.

Moving on to step 10:
The number 807 fits into 6630 8 times, leaving a remainder of 174.
Use 8 as the next digit of our solution. 
Result so far: 107739.18
Subtract 6456 from 6630 to get 174.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1740, and continue the process.

Let's proceed to step 11:
If we divide 1740 by 807, we get 2 and a remainder of 126.
Record the quotient 2 as the next digit in the result. 
Result so far: 107739.182
Subtract 1614 from 1740 to get 126.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

Moving on to step 12:
When dividing 1260 by 807, we get 1 with a remainder of 453.
Write down 1 as next digit of the result. 
Result so far: 107739.1821
Subtracting 807 from 1260 leaves us with 453.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4530, and continue the process.

On to step 13:
4530 divided by 807 is 5 with a remainder of 495.
The next digit of our result is 5. 
Result so far: 107739.18215
Deduct 4035 from 4530 and we're left with 495.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4950, and continue the process.

Let's proceed to step 14:
807 can be fit into 4950 6 times, resulting in a remainder of 108.
Put 6 as the next digit of the answer. 
Result so far: 107739.182156
Subtract 4842 from 4950 to get 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Advancing to step 15:
The number 807 fits into 1080 1 times, leaving a remainder of 273.
The number 1 becomes the next digit in our result. 
Result so far: 107739.1821561
Subtract 807 from 1080 to get 273.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2730, and continue the process.

Going ahead to step 16:
2730 divided by 807 is 3 with a remainder of 309.
Write down 3 as next digit of the result. 
Result so far: 107739.18215613
If we subtract 2421 from 2730, we get 309.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3090, and continue the process.

The final outcome is 107739.18215613, with a leftover of 3.09e-07.
