91316458 ÷ 807 
We want to figure out the number of times 91316458 can be divided by 807.

Step 1:
807 goes into 9 0 times with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Include the next digit (1) from the dividend after 9, then repeat: 91 / 807

On to step 2:
The number 807 fits into 91 0 times, leaving a remainder of 91.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 91, we get 91.
Bring next digit (3) of the dividend behind the 91 and repeat the process: 913 / 807

Let's proceed to step 3:
The number 807 fits into 913 1 times, leaving a remainder of 106.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 807 from 913, we get 106.
Take the next digit (1) from the dividend and append it to 106, then repeat: 1061 / 807

Moving on to step 4:
807 can be fit into 1061 1 times, resulting in a remainder of 254.
The next digit of our result is 1. 
Result so far: 11.0
If we subtract 807 from 1061, we get 254.
Append the next digit (6) from the dividend to 254 and continue with: 2546 / 807

Advancing to step 5:
807 can be fit into 2546 3 times, resulting in a remainder of 125.
Write down 3 as next digit of the result. 
Result so far: 113.0
Subtracting 2421 from 2546 leaves us with 125.
Grab the next digit (4) from the dividend, add it to 125, then carry on: 1254 / 807

Let's proceed to step 6:
807 goes into 1254 1 times with a remainder of 447.
The number 1 becomes the next digit in our result. 
Result so far: 1131.0
Subtract 807 from 1254 to get 447.
Bring next digit (5) of the dividend behind the 447 and repeat the process: 4475 / 807

Step 7:
If we divide 4475 by 807, we get 5 and a remainder of 440.
Put 5 as the next digit of the answer. 
Result so far: 11315.0
The remainder is 440 after subtracting 4035 from 4475.
Include the next digit (8) from the dividend after 440, then repeat: 4408 / 807

Moving on to step 8:
If we divide 4408 by 807, we get 5 and a remainder of 373.
Write down 5 as next digit of the result. 
Result so far: 113155.0
If we subtract 4035 from 4408, we get 373.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3730, and continue the process.

Going ahead to step 9:
The number 807 fits into 3730 4 times, leaving a remainder of 502.
Record the quotient 4 as the next digit in the result. 
Result so far: 113155.4
The remainder is 502 after subtracting 3228 from 3730.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5020, and continue the process.

Step 10:
5020 divided by 807 is 6 with a remainder of 178.
Record the quotient 6 as the next digit in the result. 
Result so far: 113155.46
Subtracting 4842 from 5020 leaves us with 178.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1780, and continue the process.

Step 11:
When dividing 1780 by 807, we get 2 with a remainder of 166.
Use 2 as the next digit of our solution. 
Result so far: 113155.462
If we take 1614 away from 1780, we end up with 166.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1660, and continue the process.

On to step 12:
1660 divided by 807 is 2 with a remainder of 46.
Record the quotient 2 as the next digit in the result. 
Result so far: 113155.4622
If we subtract 1614 from 1660, we get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Our division results in 113155.4622 with a remaining 0.00046.
