We're dividing 78137445 by 437 
Let's see how many times 437 fits into 78137445.

On to step 1:
If we divide 7 by 437, we get 0 and a remainder of 7.
Write down 0 as next digit of the result. 
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 / 437

Going ahead to step 2:
The number 437 fits into 78 0 times, leaving a remainder of 78.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 78, we get 78.
Append the next digit (1) from the dividend to 78 and continue with: 781 / 437

On to step 3:
If we divide 781 by 437, we get 1 and a remainder of 344.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 437 from 781 leaves us with 344.
Append the next digit (3) from the dividend to 344 and continue with: 3443 / 437

Going ahead to step 4:
3443 divided by 437 is 7 with a remainder of 384.
The number 7 becomes the next digit in our result. 
Result so far: 17.0
If we subtract 3059 from 3443, we get 384.
Append the next digit (7) from the dividend to 384 and continue with: 3847 / 437

Moving on to step 5:
3847 divided by 437 is 8 with a remainder of 351.
The number 8 becomes the next digit in our result. 
Result so far: 178.0
Subtract 3496 from 3847 to get 351.
Include the next digit (4) from the dividend after 351, then repeat: 3514 / 437

Advancing to step 6:
The number 437 fits into 3514 8 times, leaving a remainder of 18.
The next digit of our result is 8. 
Result so far: 1788.0
If we subtract 3496 from 3514, we get 18.
Append the next digit (4) from the dividend to 18 and continue with: 184 / 437

Going ahead to step 7:
437 goes into 184 0 times with a remainder of 184.
Write down 0 as next digit of the result. 
Result so far: 17880.0
Subtracting 0 from 184 leaves us with 184.
Bring next digit (5) of the dividend behind the 184 and repeat the process: 1845 / 437

Step 8:
If we divide 1845 by 437, we get 4 and a remainder of 97.
The next digit of our result is 4. 
Result so far: 178804.0
Deduct 1748 from 1845 and we're left with 97.
Since there are no more digits in the dividend, we add a zero to the remainder making it 970, and continue the process.

Let's proceed to step 9:
The number 437 fits into 970 2 times, leaving a remainder of 96.
The next digit of our result is 2. 
Result so far: 178804.2
Subtracting 874 from 970 leaves us with 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Advancing to step 10:
960 divided by 437 is 2 with a remainder of 86.
Use 2 as the next digit of our solution. 
Result so far: 178804.22
If we subtract 874 from 960, we get 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

The final result is 178804.22 with a remainder of 0.086.
