Let's divide 78237006 by 309
We want to figure out the number of times 78237006 can be divided by 309.

Let's proceed to step 1:
7 divided by 309 is 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Grab the next digit (8) from the dividend, add it to 7, then carry on: 78 / 309

Moving on to step 2:
309 can be fit into 78 0 times, resulting in a remainder of 78.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 78 leaves us with 78.
Grab the next digit (2) from the dividend, add it to 78, then carry on: 782 / 309

Advancing to step 3:
If we divide 782 by 309, we get 2 and a remainder of 164.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Deduct 618 from 782 and we're left with 164.
Bring next digit (3) of the dividend behind the 164 and repeat the process: 1643 / 309

Step 4:
When dividing 1643 by 309, we get 5 with a remainder of 98.
Write down 5 as next digit of the result. 
Result so far: 25.0
The remainder is 98 after subtracting 1545 from 1643.
Fetch the next digit (7) from the dividend, attach it to 98 and continue: 987 / 309

Going ahead to step 5:
987 divided by 309 is 3 with a remainder of 60.
Use 3 as the next digit of our solution. 
Result so far: 253.0
If we subtract 927 from 987, we get 60.
Bring next digit (0) of the dividend behind the 60 and repeat the process: 600 / 309

On to step 6:
If we divide 600 by 309, we get 1 and a remainder of 291.
Write down 1 as next digit of the result. 
Result so far: 2531.0
Subtract 309 from 600 to get 291.
Append the next digit (0) from the dividend to 291 and continue with: 2910 / 309

Let's proceed to step 7:
2910 divided by 309 is 9 with a remainder of 129.
Use 9 as the next digit of our solution. 
Result so far: 25319.0
Subtracting 2781 from 2910 leaves us with 129.
Take the next digit (6) from the dividend and append it to 129, then repeat: 1296 / 309

Going ahead to step 8:
The number 309 fits into 1296 4 times, leaving a remainder of 60.
The number 4 becomes the next digit in our result. 
Result so far: 253194.0
If we subtract 1236 from 1296, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 9:
309 goes into 600 1 times with a remainder of 291.
Record the quotient 1 as the next digit in the result. 
Result so far: 253194.1
If we take 309 away from 600, we end up with 291.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2910, and continue the process.

Advancing to step 10:
2910 divided by 309 is 9 with a remainder of 129.
Write down 9 as next digit of the result. 
Result so far: 253194.19
Deduct 2781 from 2910 and we're left with 129.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1290, and continue the process.

Going ahead to step 11:
1290 divided by 309 is 4 with a remainder of 54.
The next digit of our result is 4. 
Result so far: 253194.194
The remainder is 54 after subtracting 1236 from 1290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Going ahead to step 12:
309 can be fit into 540 1 times, resulting in a remainder of 231.
Write down 1 as next digit of the result. 
Result so far: 253194.1941
If we subtract 309 from 540, we get 231.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2310, and continue the process.

Let's proceed to step 13:
If we divide 2310 by 309, we get 7 and a remainder of 147.
Record the quotient 7 as the next digit in the result. 
Result so far: 253194.19417
The remainder is 147 after subtracting 2163 from 2310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1470, and continue the process.

Advancing to step 14:
When dividing 1470 by 309, we get 4 with a remainder of 234.
The next digit of our result is 4. 
Result so far: 253194.194174
If we subtract 1236 from 1470, we get 234.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2340, and continue the process.

Going ahead to step 15:
The number 309 fits into 2340 7 times, leaving a remainder of 177.
Write down 7 as next digit of the result. 
Result so far: 253194.1941747
If we subtract 2163 from 2340, we get 177.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1770, and continue the process.

On to step 16:
1770 divided by 309 is 5 with a remainder of 225.
The next digit of our result is 5. 
Result so far: 253194.19417475
Deduct 1545 from 1770 and we're left with 225.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2250, and continue the process.

The quotient of the division is 253194.19417475, and the remainder is 2.25e-07.
