Let's divide 78744648 by 404
We want to divide 78744648 by 404.

Step 1:
7 divided by 404 is 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Bring next digit (8) of the dividend behind the 7 and repeat the process: 78 / 404

Going ahead to step 2:
404 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
If we take 0 away from 78, we end up with 78.
Fetch the next digit (7) from the dividend, attach it to 78 and continue: 787 / 404

Advancing to step 3:
404 can be fit into 787 1 times, resulting in a remainder of 383.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 383 after subtracting 404 from 787.
Bring next digit (4) of the dividend behind the 383 and repeat the process: 3834 / 404

Step 4:
404 goes into 3834 9 times with a remainder of 198.
The next digit of our result is 9. 
Result so far: 19.0
Subtract 3636 from 3834 to get 198.
Include the next digit (4) from the dividend after 198, then repeat: 1984 / 404

Advancing to step 5:
When dividing 1984 by 404, we get 4 with a remainder of 368.
Put 4 as the next digit of the answer. 
Result so far: 194.0
Subtract 1616 from 1984 to get 368.
Include the next digit (6) from the dividend after 368, then repeat: 3686 / 404

Step 6:
3686 divided by 404 is 9 with a remainder of 50.
Put 9 as the next digit of the answer. 
Result so far: 1949.0
The remainder is 50 after subtracting 3636 from 3686.
Fetch the next digit (4) from the dividend, attach it to 50 and continue: 504 / 404

Going ahead to step 7:
The number 404 fits into 504 1 times, leaving a remainder of 100.
Put 1 as the next digit of the answer. 
Result so far: 19491.0
Subtracting 404 from 504 leaves us with 100.
Grab the next digit (8) from the dividend, add it to 100, then carry on: 1008 / 404

On to step 8:
When dividing 1008 by 404, we get 2 with a remainder of 200.
The number 2 becomes the next digit in our result. 
Result so far: 194912.0
Subtract 808 from 1008 to get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Step 9:
The number 404 fits into 2000 4 times, leaving a remainder of 384.
Write down 4 as next digit of the result. 
Result so far: 194912.4
If we subtract 1616 from 2000, we get 384.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

Moving on to step 10:
404 goes into 3840 9 times with a remainder of 204.
Record the quotient 9 as the next digit in the result. 
Result so far: 194912.49
Subtract 3636 from 3840 to get 204.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2040, and continue the process.

Moving on to step 11:
2040 divided by 404 is 5 with a remainder of 20.
Use 5 as the next digit of our solution. 
Result so far: 194912.495
If we subtract 2020 from 2040, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 12:
If we divide 200 by 404, we get 0 and a remainder of 200.
Use 0 as the next digit of our solution. 
Result so far: 194912.495
If we subtract 0 from 200, we get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Let's proceed to step 13:
404 goes into 2000 4 times with a remainder of 384.
Put 4 as the next digit of the answer. 
Result so far: 194912.49504
Subtracting 1616 from 2000 leaves us with 384.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

On to step 14:
404 can be fit into 3840 9 times, resulting in a remainder of 204.
Put 9 as the next digit of the answer. 
Result so far: 194912.495049
The remainder is 204 after subtracting 3636 from 3840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2040, and continue the process.

Step 15:
If we divide 2040 by 404, we get 5 and a remainder of 20.
Write down 5 as next digit of the result. 
Result so far: 194912.4950495
Deduct 2020 from 2040 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 16:
If we divide 200 by 404, we get 0 and a remainder of 200.
The number 0 becomes the next digit in our result. 
Result so far: 194912.4950495
Deduct 0 from 200 and we're left with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

The final outcome is 194912.4950495, with a leftover of 2e-07.
