We're dividing 77884481 by 438 
We're looking to find how many times 438 goes into 77884481.

On to step 1:
438 goes into 7 0 times with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Include the next digit (7) from the dividend after 7, then repeat: 77 / 438

Going ahead to step 2:
77 divided by 438 is 0 with a remainder of 77.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 77 after subtracting 0 from 77.
Take the next digit (8) from the dividend and append it to 77, then repeat: 778 / 438

Moving on to step 3:
778 divided by 438 is 1 with a remainder of 340.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 438 from 778 leaves us with 340.
Fetch the next digit (8) from the dividend, attach it to 340 and continue: 3408 / 438

On to step 4:
438 goes into 3408 7 times with a remainder of 342.
The next digit of our result is 7. 
Result so far: 17.0
Deduct 3066 from 3408 and we're left with 342.
Fetch the next digit (4) from the dividend, attach it to 342 and continue: 3424 / 438

Step 5:
If we divide 3424 by 438, we get 7 and a remainder of 358.
Use 7 as the next digit of our solution. 
Result so far: 177.0
Subtract 3066 from 3424 to get 358.
Grab the next digit (4) from the dividend, add it to 358, then carry on: 3584 / 438

Moving on to step 6:
The number 438 fits into 3584 8 times, leaving a remainder of 80.
Record the quotient 8 as the next digit in the result. 
Result so far: 1778.0
Subtracting 3504 from 3584 leaves us with 80.
Append the next digit (8) from the dividend to 80 and continue with: 808 / 438

Going ahead to step 7:
438 can be fit into 808 1 times, resulting in a remainder of 370.
Put 1 as the next digit of the answer. 
Result so far: 17781.0
Deduct 438 from 808 and we're left with 370.
Include the next digit (1) from the dividend after 370, then repeat: 3701 / 438

Going ahead to step 8:
If we divide 3701 by 438, we get 8 and a remainder of 197.
Record the quotient 8 as the next digit in the result. 
Result so far: 177818.0
The remainder is 197 after subtracting 3504 from 3701.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1970, and continue the process.

Moving on to step 9:
438 goes into 1970 4 times with a remainder of 218.
Record the quotient 4 as the next digit in the result. 
Result so far: 177818.4
Deduct 1752 from 1970 and we're left with 218.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2180, and continue the process.

Advancing to step 10:
438 goes into 2180 4 times with a remainder of 428.
The next digit of our result is 4. 
Result so far: 177818.44
Deduct 1752 from 2180 and we're left with 428.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4280, and continue the process.

In conclusion, the division gives 177818.44 with a balance of 0.428.
