Let's divide 78829186 by 309
We want to figure out the number of times 78829186 can be divided by 309.

Moving on to step 1:
309 can be fit into 7 0 times, resulting in a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Take the next digit (8) from the dividend and append it to 7, then repeat: 78 / 309

Moving on to step 2:
309 goes into 78 0 times with a remainder of 78.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 78 and we're left with 78.
Take the next digit (8) from the dividend and append it to 78, then repeat: 788 / 309

Step 3:
309 goes into 788 2 times with a remainder of 170.
The next digit of our result is 2. 
Result so far: 2.0
The remainder is 170 after subtracting 618 from 788.
Append the next digit (2) from the dividend to 170 and continue with: 1702 / 309

Moving on to step 4:
309 goes into 1702 5 times with a remainder of 157.
Use 5 as the next digit of our solution. 
Result so far: 25.0
If we subtract 1545 from 1702, we get 157.
Include the next digit (9) from the dividend after 157, then repeat: 1579 / 309

Advancing to step 5:
309 can be fit into 1579 5 times, resulting in a remainder of 34.
Write down 5 as next digit of the result. 
Result so far: 255.0
Subtract 1545 from 1579 to get 34.
Append the next digit (1) from the dividend to 34 and continue with: 341 / 309

Moving on to step 6:
When dividing 341 by 309, we get 1 with a remainder of 32.
Use 1 as the next digit of our solution. 
Result so far: 2551.0
Subtract 309 from 341 to get 32.
Take the next digit (8) from the dividend and append it to 32, then repeat: 328 / 309

Advancing to step 7:
328 divided by 309 is 1 with a remainder of 19.
Use 1 as the next digit of our solution. 
Result so far: 25511.0
Subtract 309 from 328 to get 19.
Include the next digit (6) from the dividend after 19, then repeat: 196 / 309

Moving on to step 8:
The number 309 fits into 196 0 times, leaving a remainder of 196.
The next digit of our result is 0. 
Result so far: 255110.0
Subtracting 0 from 196 leaves us with 196.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1960, and continue the process.

Step 9:
1960 divided by 309 is 6 with a remainder of 106.
Write down 6 as next digit of the result. 
Result so far: 255110.6
Subtracting 1854 from 1960 leaves us with 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

Going ahead to step 10:
1060 divided by 309 is 3 with a remainder of 133.
Write down 3 as next digit of the result. 
Result so far: 255110.63
Subtract 927 from 1060 to get 133.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1330, and continue the process.

Moving on to step 11:
The number 309 fits into 1330 4 times, leaving a remainder of 94.
The next digit of our result is 4. 
Result so far: 255110.634
If we take 1236 away from 1330, we end up with 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

Step 12:
309 goes into 940 3 times with a remainder of 13.
Record the quotient 3 as the next digit in the result. 
Result so far: 255110.6343
The remainder is 13 after subtracting 927 from 940.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Going ahead to step 13:
The number 309 fits into 130 0 times, leaving a remainder of 130.
Use 0 as the next digit of our solution. 
Result so far: 255110.6343
Subtracting 0 from 130 leaves us with 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Moving on to step 14:
When dividing 1300 by 309, we get 4 with a remainder of 64.
Write down 4 as next digit of the result. 
Result so far: 255110.634304
The remainder is 64 after subtracting 1236 from 1300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Advancing to step 15:
640 divided by 309 is 2 with a remainder of 22.
The number 2 becomes the next digit in our result. 
Result so far: 255110.6343042
If we take 618 away from 640, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 16:
The number 309 fits into 220 0 times, leaving a remainder of 220.
Write down 0 as next digit of the result. 
Result so far: 255110.6343042
Deduct 0 from 220 and we're left with 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

In conclusion, the division gives 255110.6343042 with a balance of 2.2e-07.
