We're dividing 78571348 by 309 
We're looking to find how many times 309 goes into 78571348.

Let's proceed to step 1:
When dividing 7 by 309, we get 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Include the next digit (8) from the dividend after 7, then repeat: 78 / 309

Moving on to step 2:
78 divided by 309 is 0 with a remainder of 78.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 78 leaves us with 78.
Append the next digit (5) from the dividend to 78 and continue with: 785 / 309

Step 3:
The number 309 fits into 785 2 times, leaving a remainder of 167.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtracting 618 from 785 leaves us with 167.
Bring next digit (7) of the dividend behind the 167 and repeat the process: 1677 / 309

Let's proceed to step 4:
309 can be fit into 1677 5 times, resulting in a remainder of 132.
Put 5 as the next digit of the answer. 
Result so far: 25.0
Deduct 1545 from 1677 and we're left with 132.
Fetch the next digit (1) from the dividend, attach it to 132 and continue: 1321 / 309

Let's proceed to step 5:
If we divide 1321 by 309, we get 4 and a remainder of 85.
Record the quotient 4 as the next digit in the result. 
Result so far: 254.0
If we take 1236 away from 1321, we end up with 85.
Fetch the next digit (3) from the dividend, attach it to 85 and continue: 853 / 309

Let's proceed to step 6:
The number 309 fits into 853 2 times, leaving a remainder of 235.
The number 2 becomes the next digit in our result. 
Result so far: 2542.0
If we take 618 away from 853, we end up with 235.
Fetch the next digit (4) from the dividend, attach it to 235 and continue: 2354 / 309

Moving on to step 7:
When dividing 2354 by 309, we get 7 with a remainder of 191.
The next digit of our result is 7. 
Result so far: 25427.0
If we subtract 2163 from 2354, we get 191.
Take the next digit (8) from the dividend and append it to 191, then repeat: 1918 / 309

Advancing to step 8:
When dividing 1918 by 309, we get 6 with a remainder of 64.
Record the quotient 6 as the next digit in the result. 
Result so far: 254276.0
The remainder is 64 after subtracting 1854 from 1918.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Step 9:
When dividing 640 by 309, we get 2 with a remainder of 22.
Put 2 as the next digit of the answer. 
Result so far: 254276.2
Subtract 618 from 640 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 10:
The number 309 fits into 220 0 times, leaving a remainder of 220.
The next digit of our result is 0. 
Result so far: 254276.2
Subtract 0 from 220 to get 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Step 11:
309 goes into 2200 7 times with a remainder of 37.
Use 7 as the next digit of our solution. 
Result so far: 254276.207
If we subtract 2163 from 2200, we get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Advancing to step 12:
The number 309 fits into 370 1 times, leaving a remainder of 61.
Write down 1 as next digit of the result. 
Result so far: 254276.2071
Deduct 309 from 370 and we're left with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Step 13:
If we divide 610 by 309, we get 1 and a remainder of 301.
The number 1 becomes the next digit in our result. 
Result so far: 254276.20711
The remainder is 301 after subtracting 309 from 610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3010, and continue the process.

Our division results in 254276.20711 with a remaining 0.000301.
