We're dividing 78987662 by 308 
We're looking to find how many times 308 goes into 78987662.

On to step 1:
308 goes into 7 0 times 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.
Fetch the next digit (8) from the dividend, attach it to 7 and continue: 78 / 308

Let's proceed to step 2:
308 can be fit into 78 0 times, resulting in a remainder of 78.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 78 after subtracting 0 from 78.
Grab the next digit (9) from the dividend, add it to 78, then carry on: 789 / 308

Going ahead to step 3:
308 goes into 789 2 times with a remainder of 173.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Deduct 616 from 789 and we're left with 173.
Append the next digit (8) from the dividend to 173 and continue with: 1738 / 308

Advancing to step 4:
308 goes into 1738 5 times with a remainder of 198.
The next digit of our result is 5. 
Result so far: 25.0
Deduct 1540 from 1738 and we're left with 198.
Fetch the next digit (7) from the dividend, attach it to 198 and continue: 1987 / 308

Advancing to step 5:
If we divide 1987 by 308, we get 6 and a remainder of 139.
Write down 6 as next digit of the result. 
Result so far: 256.0
Subtract 1848 from 1987 to get 139.
Fetch the next digit (6) from the dividend, attach it to 139 and continue: 1396 / 308

Step 6:
308 goes into 1396 4 times with a remainder of 164.
The next digit of our result is 4. 
Result so far: 2564.0
Deduct 1232 from 1396 and we're left with 164.
Take the next digit (6) from the dividend and append it to 164, then repeat: 1646 / 308

Moving on to step 7:
If we divide 1646 by 308, we get 5 and a remainder of 106.
The number 5 becomes the next digit in our result. 
Result so far: 25645.0
Deduct 1540 from 1646 and we're left with 106.
Grab the next digit (2) from the dividend, add it to 106, then carry on: 1062 / 308

Going ahead to step 8:
308 goes into 1062 3 times with a remainder of 138.
The number 3 becomes the next digit in our result. 
Result so far: 256453.0
If we subtract 924 from 1062, we get 138.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1380, and continue the process.

Step 9:
When dividing 1380 by 308, we get 4 with a remainder of 148.
Write down 4 as next digit of the result. 
Result so far: 256453.4
If we subtract 1232 from 1380, we get 148.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

Moving on to step 10:
308 goes into 1480 4 times with a remainder of 248.
Put 4 as the next digit of the answer. 
Result so far: 256453.44
If we take 1232 away from 1480, we end up with 248.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

The final result is 256453.44 with a remainder of 0.248.
