We divide 78366780 by 415
Our goal is to divide 78366780 by 415.

Let's proceed to step 1:
If we divide 7 by 415, we get 0 and a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Take the next digit (8) from the dividend and append it to 7, then repeat: 78 / 415

Advancing to step 2:
The number 415 fits into 78 0 times, leaving a remainder of 78.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 78 leaves us with 78.
Grab the next digit (3) from the dividend, add it to 78, then carry on: 783 / 415

Going ahead to step 3:
415 goes into 783 1 times with a remainder of 368.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 415 from 783 and we're left with 368.
Append the next digit (6) from the dividend to 368 and continue with: 3686 / 415

Advancing to step 4:
415 goes into 3686 8 times with a remainder of 366.
Put 8 as the next digit of the answer. 
Result so far: 18.0
The remainder is 366 after subtracting 3320 from 3686.
Append the next digit (6) from the dividend to 366 and continue with: 3666 / 415

Step 5:
If we divide 3666 by 415, we get 8 and a remainder of 346.
Write down 8 as next digit of the result. 
Result so far: 188.0
Subtracting 3320 from 3666 leaves us with 346.
Include the next digit (7) from the dividend after 346, then repeat: 3467 / 415

Step 6:
3467 divided by 415 is 8 with a remainder of 147.
Use 8 as the next digit of our solution. 
Result so far: 1888.0
If we subtract 3320 from 3467, we get 147.
Grab the next digit (8) from the dividend, add it to 147, then carry on: 1478 / 415

Advancing to step 7:
If we divide 1478 by 415, we get 3 and a remainder of 233.
Write down 3 as next digit of the result. 
Result so far: 18883.0
Deduct 1245 from 1478 and we're left with 233.
Fetch the next digit (0) from the dividend, attach it to 233 and continue: 2330 / 415

On to step 8:
If we divide 2330 by 415, we get 5 and a remainder of 255.
The next digit of our result is 5. 
Result so far: 188835.0
Deduct 2075 from 2330 and we're left with 255.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2550, and continue the process.

On to step 9:
415 goes into 2550 6 times with a remainder of 60.
Put 6 as the next digit of the answer. 
Result so far: 188835.6
Subtracting 2490 from 2550 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 10:
415 can be fit into 600 1 times, resulting in a remainder of 185.
Use 1 as the next digit of our solution. 
Result so far: 188835.61
If we subtract 415 from 600, we get 185.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1850, and continue the process.

Step 11:
The number 415 fits into 1850 4 times, leaving a remainder of 190.
Use 4 as the next digit of our solution. 
Result so far: 188835.614
Subtract 1660 from 1850 to get 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Let's proceed to step 12:
The number 415 fits into 1900 4 times, leaving a remainder of 240.
Record the quotient 4 as the next digit in the result. 
Result so far: 188835.6144
The remainder is 240 after subtracting 1660 from 1900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

The quotient of the division is 188835.6144, and the remainder is 0.0024.
