We're dividing 78438987 by 532 
We want to figure out the number of times 78438987 can be divided by 532.

Step 1:
When dividing 7 by 532, we get 0 with a remainder of 7.
The next digit of our result is 0. 
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 / 532

Going ahead to step 2:
532 goes into 78 0 times with a remainder of 78.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 78 after subtracting 0 from 78.
Include the next digit (4) from the dividend after 78, then repeat: 784 / 532

Going ahead to step 3:
When dividing 784 by 532, we get 1 with a remainder of 252.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 532 from 784 to get 252.
Append the next digit (3) from the dividend to 252 and continue with: 2523 / 532

Going ahead to step 4:
532 can be fit into 2523 4 times, resulting in a remainder of 395.
Put 4 as the next digit of the answer. 
Result so far: 14.0
If we subtract 2128 from 2523, we get 395.
Bring next digit (8) of the dividend behind the 395 and repeat the process: 3958 / 532

Going ahead to step 5:
If we divide 3958 by 532, we get 7 and a remainder of 234.
The number 7 becomes the next digit in our result. 
Result so far: 147.0
If we subtract 3724 from 3958, we get 234.
Bring next digit (9) of the dividend behind the 234 and repeat the process: 2349 / 532

On to step 6:
When dividing 2349 by 532, we get 4 with a remainder of 221.
The number 4 becomes the next digit in our result. 
Result so far: 1474.0
Subtracting 2128 from 2349 leaves us with 221.
Include the next digit (8) from the dividend after 221, then repeat: 2218 / 532

On to step 7:
2218 divided by 532 is 4 with a remainder of 90.
The next digit of our result is 4. 
Result so far: 14744.0
If we subtract 2128 from 2218, we get 90.
Grab the next digit (7) from the dividend, add it to 90, then carry on: 907 / 532

Let's proceed to step 8:
907 divided by 532 is 1 with a remainder of 375.
Record the quotient 1 as the next digit in the result. 
Result so far: 147441.0
Subtract 532 from 907 to get 375.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3750, and continue the process.

On to step 9:
The number 532 fits into 3750 7 times, leaving a remainder of 26.
Use 7 as the next digit of our solution. 
Result so far: 147441.7
If we subtract 3724 from 3750, we get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

On to step 10:
The number 532 fits into 260 0 times, leaving a remainder of 260.
Write down 0 as next digit of the result. 
Result so far: 147441.7
Deduct 0 from 260 and we're left with 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Going ahead to step 11:
If we divide 2600 by 532, we get 4 and a remainder of 472.
Record the quotient 4 as the next digit in the result. 
Result so far: 147441.704
The remainder is 472 after subtracting 2128 from 2600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4720, and continue the process.

Moving on to step 12:
If we divide 4720 by 532, we get 8 and a remainder of 464.
Put 8 as the next digit of the answer. 
Result so far: 147441.7048
Subtract 4256 from 4720 to get 464.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4640, and continue the process.

Advancing to step 13:
The number 532 fits into 4640 8 times, leaving a remainder of 384.
Record the quotient 8 as the next digit in the result. 
Result so far: 147441.70488
Deduct 4256 from 4640 and we're left 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.

After the division, we end up with 147441.70488 and a remainder of 0.000384.
