We're dividing 91178206 by 309 
We want to divide 91178206 by 309.

Let's proceed to step 1:
The number 309 fits into 9 0 times, leaving a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Grab the next digit (1) from the dividend, add it to 9, then carry on: 91 / 309

Moving on to step 2:
If we divide 91 by 309, we get 0 and a remainder of 91.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 91 and we're left with 91.
Append the next digit (1) from the dividend to 91 and continue with: 911 / 309

On to step 3:
911 divided by 309 is 2 with a remainder of 293.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtracting 618 from 911 leaves us with 293.
Bring next digit (7) of the dividend behind the 293 and repeat the process: 2937 / 309

Going ahead to step 4:
309 goes into 2937 9 times with a remainder of 156.
Record the quotient 9 as the next digit in the result. 
Result so far: 29.0
The remainder is 156 after subtracting 2781 from 2937.
Bring next digit (8) of the dividend behind the 156 and repeat the process: 1568 / 309

On to step 5:
If we divide 1568 by 309, we get 5 and a remainder of 23.
The number 5 becomes the next digit in our result. 
Result so far: 295.0
If we take 1545 away from 1568, we end up with 23.
Fetch the next digit (2) from the dividend, attach it to 23 and continue: 232 / 309

On to step 6:
When dividing 232 by 309, we get 0 with a remainder of 232.
Put 0 as the next digit of the answer. 
Result so far: 2950.0
Subtract 0 from 232 to get 232.
Grab the next digit (0) from the dividend, add it to 232, then carry on: 2320 / 309

Moving on to step 7:
309 goes into 2320 7 times with a remainder of 157.
Use 7 as the next digit of our solution. 
Result so far: 29507.0
Deduct 2163 from 2320 and we're left with 157.
Include the next digit (6) from the dividend after 157, then repeat: 1576 / 309

Let's proceed to step 8:
When dividing 1576 by 309, we get 5 with a remainder of 31.
Put 5 as the next digit of the answer. 
Result so far: 295075.0
Subtracting 1545 from 1576 leaves us with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Moving on to step 9:
310 divided by 309 is 1 with a remainder of 1.
Record the quotient 1 as the next digit in the result. 
Result so far: 295075.1
The remainder is 1 after subtracting 309 from 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 10:
309 goes into 10 0 times with a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 295075.1
If we take 0 away from 10, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 11:
The number 309 fits into 100 0 times, leaving a remainder of 100.
Write down 0 as next digit of the result. 
Result so far: 295075.1
If we subtract 0 from 100, we get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

The final outcome is 295075.1, with a leftover of 0.01.
