78597678 divided by 418 
Our goal is to divide 78597678 by 418.

On to step 1:
If we divide 7 by 418, we get 0 and a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Append the next digit (8) from the dividend to 7 and continue with: 78 / 418

Step 2:
If we divide 78 by 418, we get 0 and a remainder of 78.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 78 leaves us with 78.
Append the next digit (5) from the dividend to 78 and continue with: 785 / 418

Step 3:
The number 418 fits into 785 1 times, leaving a remainder of 367.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 418 away from 785, we end up with 367.
Fetch the next digit (9) from the dividend, attach it to 367 and continue: 3679 / 418

Let's proceed to step 4:
When dividing 3679 by 418, we get 8 with a remainder of 335.
The next digit of our result is 8. 
Result so far: 18.0
The remainder is 335 after subtracting 3344 from 3679.
Append the next digit (7) from the dividend to 335 and continue with: 3357 / 418

Moving on to step 5:
418 can be fit into 3357 8 times, resulting in a remainder of 13.
Record the quotient 8 as the next digit in the result. 
Result so far: 188.0
The remainder is 13 after subtracting 3344 from 3357.
Include the next digit (6) from the dividend after 13, then repeat: 136 / 418

Moving on to step 6:
If we divide 136 by 418, we get 0 and a remainder of 136.
Record the quotient 0 as the next digit in the result. 
Result so far: 1880.0
If we subtract 0 from 136, we get 136.
Take the next digit (7) from the dividend and append it to 136, then repeat: 1367 / 418

On to step 7:
The number 418 fits into 1367 3 times, leaving a remainder of 113.
The next digit of our result is 3. 
Result so far: 18803.0
Deduct 1254 from 1367 and we're left with 113.
Grab the next digit (8) from the dividend, add it to 113, then carry on: 1138 / 418

Step 8:
If we divide 1138 by 418, we get 2 and a remainder of 302.
Write down 2 as next digit of the result. 
Result so far: 188032.0
Subtracting 836 from 1138 leaves us with 302.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3020, and continue the process.

Step 9:
418 goes into 3020 7 times with a remainder of 94.
Record the quotient 7 as the next digit in the result. 
Result so far: 188032.7
Subtract 2926 from 3020 to get 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

On to step 10:
If we divide 940 by 418, we get 2 and a remainder of 104.
The number 2 becomes the next digit in our result. 
Result so far: 188032.72
Subtract 836 from 940 to get 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Going ahead to step 11:
When dividing 1040 by 418, we get 2 with a remainder of 204.
Put 2 as the next digit of the answer. 
Result so far: 188032.722
Subtracting 836 from 1040 leaves us with 204.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2040, and continue the process.

The final outcome is 188032.722, with a leftover of 0.0204.
