78718637 divided by 448 
We want to figure out the number of times 78718637 can be divided by 448.

Step 1:
When dividing 7 by 448, we get 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
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 / 448

On to step 2:
If we divide 78 by 448, we get 0 and a remainder of 78.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 78 leaves us with 78.
Take the next digit (7) from the dividend and append it to 78, then repeat: 787 / 448

Moving on to step 3:
When dividing 787 by 448, we get 1 with a remainder of 339.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 448 away from 787, we end up with 339.
Append the next digit (1) from the dividend to 339 and continue with: 3391 / 448

On to step 4:
The number 448 fits into 3391 7 times, leaving a remainder of 255.
Write down 7 as next digit of the result. 
Result so far: 17.0
Subtracting 3136 from 3391 leaves us with 255.
Take the next digit (8) from the dividend and append it to 255, then repeat: 2558 / 448

Step 5:
2558 divided by 448 is 5 with a remainder of 318.
Write down 5 as next digit of the result. 
Result so far: 175.0
If we subtract 2240 from 2558, we get 318.
Bring next digit (6) of the dividend behind the 318 and repeat the process: 3186 / 448

Advancing to step 6:
The number 448 fits into 3186 7 times, leaving a remainder of 50.
Record the quotient 7 as the next digit in the result. 
Result so far: 1757.0
Deduct 3136 from 3186 and we're left with 50.
Bring next digit (3) of the dividend behind the 50 and repeat the process: 503 / 448

Going ahead to step 7:
448 goes into 503 1 times with a remainder of 55.
Put 1 as the next digit of the answer. 
Result so far: 17571.0
The remainder is 55 after subtracting 448 from 503.
Include the next digit (7) from the dividend after 55, then repeat: 557 / 448

On to step 8:
The number 448 fits into 557 1 times, leaving a remainder of 109.
The number 1 becomes the next digit in our result. 
Result so far: 175711.0
If we take 448 away from 557, we end up with 109.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1090, and continue the process.

Going ahead to step 9:
448 can be fit into 1090 2 times, resulting in a remainder of 194.
The next digit of our result is 2. 
Result so far: 175711.2
Subtracting 896 from 1090 leaves us with 194.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1940, and continue the process.

Moving on to step 10:
If we divide 1940 by 448, we get 4 and a remainder of 148.
Use 4 as the next digit of our solution. 
Result so far: 175711.24
Deduct 1792 from 1940 and we're left with 148.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

Advancing to step 11:
The number 448 fits into 1480 3 times, leaving a remainder of 136.
The number 3 becomes the next digit in our result. 
Result so far: 175711.243
Deduct 1344 from 1480 and we're left with 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Going ahead to step 12:
If we divide 1360 by 448, we get 3 and a remainder of 16.
The next digit of our result is 3. 
Result so far: 175711.2433
If we take 1344 away from 1360, 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.

The final result is 175711.2433 with a remainder of 0.00016.
