We divide 78123736 by 305
Our goal is to divide 78123736 by 305.

Moving on to step 1:
7 divided by 305 is 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Grab the next digit (8) from the dividend, add it to 7, then carry on: 78 / 305

On to step 2:
If we divide 78 by 305, we get 0 and a remainder of 78.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 78 to get 78.
Append the next digit (1) from the dividend to 78 and continue with: 781 / 305

Step 3:
When dividing 781 by 305, we get 2 with a remainder of 171.
The next digit of our result is 2. 
Result so far: 2.0
The remainder is 171 after subtracting 610 from 781.
Grab the next digit (2) from the dividend, add it to 171, then carry on: 1712 / 305

Advancing to step 4:
1712 divided by 305 is 5 with a remainder of 187.
The number 5 becomes the next digit in our result. 
Result so far: 25.0
If we subtract 1525 from 1712, we get 187.
Take the next digit (3) from the dividend and append it to 187, then repeat: 1873 / 305

Going ahead to step 5:
305 goes into 1873 6 times with a remainder of 43.
The next digit of our result is 6. 
Result so far: 256.0
The remainder is 43 after subtracting 1830 from 1873.
Append the next digit (7) from the dividend to 43 and continue with: 437 / 305

Step 6:
305 can be fit into 437 1 times, resulting in a remainder of 132.
Write down 1 as next digit of the result. 
Result so far: 2561.0
Subtracting 305 from 437 leaves us with 132.
Bring next digit (3) of the dividend behind the 132 and repeat the process: 1323 / 305

Going ahead to step 7:
305 can be fit into 1323 4 times, resulting in a remainder of 103.
Write down 4 as next digit of the result. 
Result so far: 25614.0
If we take 1220 away from 1323, we end up with 103.
Take the next digit (6) from the dividend and append it to 103, then repeat: 1036 / 305

Step 8:
305 goes into 1036 3 times with a remainder of 121.
The number 3 becomes the next digit in our result. 
Result so far: 256143.0
Subtracting 915 from 1036 leaves us with 121.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1210, and continue the process.

Going ahead to step 9:
If we divide 1210 by 305, we get 3 and a remainder of 295.
The number 3 becomes the next digit in our result. 
Result so far: 256143.3
Deduct 915 from 1210 and we're left with 295.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2950, and continue the process.

Going ahead to step 10:
2950 divided by 305 is 9 with a remainder of 205.
Write down 9 as next digit of the result. 
Result so far: 256143.39
Subtract 2745 from 2950 to get 205.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2050, and continue the process.

Step 11:
When dividing 2050 by 305, we get 6 with a remainder of 220.
The number 6 becomes the next digit in our result. 
Result so far: 256143.396
Subtracting 1830 from 2050 leaves us 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.

Advancing to step 12:
When dividing 2200 by 305, we get 7 with a remainder of 65.
Record the quotient 7 as the next digit in the result. 
Result so far: 256143.3967
Deduct 2135 from 2200 and we're left with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Let's proceed to step 13:
The number 305 fits into 650 2 times, leaving a remainder of 40.
Record the quotient 2 as the next digit in the result. 
Result so far: 256143.39672
Subtract 610 from 650 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 14:
305 can be fit into 400 1 times, resulting in a remainder of 95.
Record the quotient 1 as the next digit in the result. 
Result so far: 256143.396721
Deduct 305 from 400 and we're left with 95.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

Let's proceed to step 15:
The number 305 fits into 950 3 times, leaving a remainder of 35.
Use 3 as the next digit of our solution. 
Result so far: 256143.3967213
Subtracting 915 from 950 leaves us with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Step 16:
305 goes into 350 1 times with a remainder of 45.
Put 1 as the next digit of the answer. 
Result so far: 256143.39672131
Subtracting 305 from 350 leaves us with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

After the division, we end up with 256143.39672131 and a remainder of 4.5e-08.
