We're dividing 18418321 by 78 
We're looking to find how many times 78 goes into 18418321.

Going ahead to step 1:
78 goes into 1 0 times with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Include the next digit (8) from the dividend after 1, then repeat: 18 / 78

Moving on to step 2:
If we divide 18 by 78, we get 0 and a remainder of 18.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 18 to get 18.
Grab the next digit (4) from the dividend, add it to 18, then carry on: 184 / 78

Moving on to step 3:
If we divide 184 by 78, we get 2 and a remainder of 28.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we take 156 away from 184, we end up with 28.
Bring next digit (1) of the dividend behind the 28 and repeat the process: 281 / 78

On to step 4:
The number 78 fits into 281 3 times, leaving a remainder of 47.
The next digit of our result is 3. 
Result so far: 23.0
Subtracting 234 from 281 leaves us with 47.
Include the next digit (8) from the dividend after 47, then repeat: 478 / 78

On to step 5:
78 can be fit into 478 6 times, resulting in a remainder of 10.
The number 6 becomes the next digit in our result. 
Result so far: 236.0
Subtracting 468 from 478 leaves us with 10.
Grab the next digit (3) from the dividend, add it to 10, then carry on: 103 / 78

On to step 6:
When dividing 103 by 78, we get 1 with a remainder of 25.
The number 1 becomes the next digit in our result. 
Result so far: 2361.0
The remainder is 25 after subtracting 78 from 103.
Bring next digit (2) of the dividend behind the 25 and repeat the process: 252 / 78

Moving on to step 7:
If we divide 252 by 78, we get 3 and a remainder of 18.
The next digit of our result is 3. 
Result so far: 23613.0
Deduct 234 from 252 and we're left with 18.
Append the next digit (1) from the dividend to 18 and continue with: 181 / 78

On to step 8:
78 can be fit into 181 2 times, resulting in a remainder of 25.
Use 2 as the next digit of our solution. 
Result so far: 236132.0
The remainder is 25 after subtracting 156 from 181.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Moving on to step 9:
78 can be fit into 250 3 times, resulting in a remainder of 16.
Write down 3 as next digit of the result. 
Result so far: 236132.3
If we take 234 away from 250, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 10:
78 can be fit into 160 2 times, resulting in a remainder of 4.
Use 2 as the next digit of our solution. 
Result so far: 236132.32
Deduct 156 from 160 and we're left 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.

Going ahead to step 11:
The number 78 fits into 40 0 times, leaving a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 236132.32
Subtract 0 from 40 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.

Moving on to step 12:
If we divide 400 by 78, we get 5 and a remainder of 10.
Use 5 as the next digit of our solution. 
Result so far: 236132.3205
If we subtract 390 from 400, we 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.

Step 13:
When dividing 100 by 78, we get 1 with a remainder of 22.
Record the quotient 1 as the next digit in the result. 
Result so far: 236132.32051
Subtract 78 from 100 to 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.

Advancing to step 14:
If we divide 220 by 78, we get 2 and a remainder of 64.
Write down 2 as next digit of the result. 
Result so far: 236132.320512
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.

Advancing to step 15:
The number 78 fits into 640 8 times, leaving a remainder of 16.
Record the quotient 8 as the next digit in the result. 
Result so far: 236132.3205128
Subtracting 624 from 640 leaves us with 16.
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 16:
78 can be fit into 160 2 times, resulting in a remainder of 4.
Put 2 as the next digit of the answer. 
Result so far: 236132.32051282
Subtracting 156 from 160 leaves us 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.

The final result is 236132.32051282 with a remainder of 4e-09.
