We're dividing 78585241 by 438 
We're looking to find how many times 438 goes into 78585241.

On to step 1:
438 can be fit into 7 0 times, resulting in a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Bring next digit (8) of the dividend behind the 7 and repeat the process: 78 / 438

Let's proceed to step 2:
78 divided by 438 is 0 with a remainder of 78.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 78 after subtracting 0 from 78.
Take the next digit (5) from the dividend and append it to 78, then repeat: 785 / 438

Step 3:
438 can be fit into 785 1 times, resulting in a remainder of 347.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 438 from 785 and we're left with 347.
Fetch the next digit (8) from the dividend, attach it to 347 and continue: 3478 / 438

On to step 4:
When dividing 3478 by 438, we get 7 with a remainder of 412.
The next digit of our result is 7. 
Result so far: 17.0
Subtract 3066 from 3478 to get 412.
Grab the next digit (5) from the dividend, add it to 412, then carry on: 4125 / 438

Advancing to step 5:
438 goes into 4125 9 times with a remainder of 183.
Write down 9 as next digit of the result. 
Result so far: 179.0
The remainder is 183 after subtracting 3942 from 4125.
Bring next digit (2) of the dividend behind the 183 and repeat the process: 1832 / 438

Let's proceed to step 6:
438 goes into 1832 4 times with a remainder of 80.
The next digit of our result is 4. 
Result so far: 1794.0
Subtract 1752 from 1832 to get 80.
Fetch the next digit (4) from the dividend, attach it to 80 and continue: 804 / 438

Let's proceed to step 7:
The number 438 fits into 804 1 times, leaving a remainder of 366.
Put 1 as the next digit of the answer. 
Result so far: 17941.0
The remainder is 366 after subtracting 438 from 804.
Take the next digit (1) from the dividend and append it to 366, then repeat: 3661 / 438

Moving on to step 8:
438 goes into 3661 8 times with a remainder of 157.
The number 8 becomes the next digit in our result. 
Result so far: 179418.0
Subtracting 3504 from 3661 leaves us with 157.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1570, and continue the process.

On to step 9:
438 goes into 1570 3 times with a remainder of 256.
Put 3 as the next digit of the answer. 
Result so far: 179418.3
If we subtract 1314 from 1570, we get 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

On to step 10:
If we divide 2560 by 438, we get 5 and a remainder of 370.
The next digit of our result is 5. 
Result so far: 179418.35
If we take 2190 away from 2560, we end up with 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3700, and continue the process.

Step 11:
The number 438 fits into 3700 8 times, leaving a remainder of 196.
Put 8 as the next digit of the answer. 
Result so far: 179418.358
Deduct 3504 from 3700 and we're left with 196.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1960, and continue the process.

Advancing to step 12:
The number 438 fits into 1960 4 times, leaving a remainder of 208.
The next digit of our result is 4. 
Result so far: 179418.3584
If we subtract 1752 from 1960, we get 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

Going ahead to step 13:
438 can be fit into 2080 4 times, resulting in a remainder of 328.
Use 4 as the next digit of our solution. 
Result so far: 179418.35844
If we subtract 1752 from 2080, we get 328.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3280, and continue the process.

The quotient of the division is 179418.35844, and the remainder is 0.000328.
