We divide 71115663 by 309
We're looking to find how many times 309 goes into 71115663.

On to step 1:
If we divide 7 by 309, we get 0 and a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Grab the next digit (1) from the dividend, add it to 7, then carry on: 71 / 309

Let's proceed to step 2:
71 divided by 309 is 0 with a remainder of 71.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 71 leaves us with 71.
Grab the next digit (1) from the dividend, add it to 71, then carry on: 711 / 309

On to step 3:
When dividing 711 by 309, we get 2 with a remainder of 93.
The next digit of our result is 2. 
Result so far: 2.0
Subtract 618 from 711 to get 93.
Grab the next digit (1) from the dividend, add it to 93, then carry on: 931 / 309

Going ahead to step 4:
309 can be fit into 931 3 times, resulting in a remainder of 4.
Write down 3 as next digit of the result. 
Result so far: 23.0
Subtract 927 from 931 to get 4.
Grab the next digit (5) from the dividend, add it to 4, then carry on: 45 / 309

Moving on to step 5:
If we divide 45 by 309, we get 0 and a remainder of 45.
Write down 0 as next digit of the result. 
Result so far: 230.0
The remainder is 45 after subtracting 0 from 45.
Fetch the next digit (6) from the dividend, attach it to 45 and continue: 456 / 309

Going ahead to step 6:
456 divided by 309 is 1 with a remainder of 147.
Record the quotient 1 as the next digit in the result. 
Result so far: 2301.0
Subtracting 309 from 456 leaves us with 147.
Fetch the next digit (6) from the dividend, attach it to 147 and continue: 1476 / 309

Let's proceed to step 7:
If we divide 1476 by 309, we get 4 and a remainder of 240.
Record the quotient 4 as the next digit in the result. 
Result so far: 23014.0
The remainder is 240 after subtracting 1236 from 1476.
Append the next digit (3) from the dividend to 240 and continue with: 2403 / 309

Step 8:
309 can be fit into 2403 7 times, resulting in a remainder of 240.
Record the quotient 7 as the next digit in the result. 
Result so far: 230147.0
The remainder is 240 after subtracting 2163 from 2403.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Going ahead to step 9:
When dividing 2400 by 309, we get 7 with a remainder of 237.
The next digit of our result is 7. 
Result so far: 230147.7
Subtract 2163 from 2400 to get 237.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2370, and continue the process.

On to step 10:
309 can be fit into 2370 7 times, resulting in a remainder of 207.
Put 7 as the next digit of the answer. 
Result so far: 230147.77
The remainder is 207 after subtracting 2163 from 2370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2070, and continue the process.

Our division results in 230147.77 with a remaining 0.207.
