307564 divided by 78 
We want to divide 307564 by 78.

Step 1:
If we divide 3 by 78, we get 0 and a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Append the next digit (0) from the dividend to 3 and continue with: 30 / 78

Advancing to step 2:
When dividing 30 by 78, we get 0 with a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 30 and we're left with 30.
Bring next digit (7) of the dividend behind the 30 and repeat the process: 307 / 78

Going ahead to step 3:
The number 78 fits into 307 3 times, leaving a remainder of 73.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Deduct 234 from 307 and we're left with 73.
Take the next digit (5) from the dividend and append it to 73, then repeat: 735 / 78

Step 4:
78 goes into 735 9 times with a remainder of 33.
Record the quotient 9 as the next digit in the result. 
Result so far: 39.0
If we take 702 away from 735, we end up with 33.
Fetch the next digit (6) from the dividend, attach it to 33 and continue: 336 / 78

Going ahead to step 5:
If we divide 336 by 78, we get 4 and a remainder of 24.
The next digit of our result is 4. 
Result so far: 394.0
Deduct 312 from 336 and we're left with 24.
Fetch the next digit (4) from the dividend, attach it to 24 and continue: 244 / 78

Let's proceed to step 6:
When dividing 244 by 78, we get 3 with a remainder of 10.
Record the quotient 3 as the next digit in the result. 
Result so far: 3943.0
Subtracting 234 from 244 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 7:
The number 78 fits into 100 1 times, leaving a remainder of 22.
Record the quotient 1 as the next digit in the result. 
Result so far: 3943.1
If we take 78 away from 100, 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.

Step 8:
When dividing 220 by 78, we get 2 with a remainder of 64.
Write down 2 as next digit of the result. 
Result so far: 3943.12
Subtract 156 from 220 to get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Let's proceed to step 9:
78 goes into 640 8 times with a remainder of 16.
Use 8 as the next digit of our solution. 
Result so far: 3943.128
The remainder is 16 after subtracting 624 from 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 10:
If we divide 160 by 78, we get 2 and a remainder of 4.
Put 2 as the next digit of the answer. 
Result so far: 3943.1282
If we take 156 away from 160, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 11:
The number 78 fits into 40 0 times, leaving a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 3943.1282
Deduct 0 from 40 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 12:
400 divided by 78 is 5 with a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 3943.128205
Subtract 390 from 400 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 13:
78 goes into 100 1 times with a remainder of 22.
The number 1 becomes the next digit in our result. 
Result so far: 3943.1282051
If we subtract 78 from 100, we 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.

Moving on to step 14:
When dividing 220 by 78, we get 2 with a remainder of 64.
Put 2 as the next digit of the answer. 
Result so far: 3943.12820512
Subtracting 156 from 220 leaves us with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

After the division, we end up with 3943.12820512 and a remainder of 6.4e-08.
