81782032 ÷ 438 
We want to figure out the number of times 81782032 can be divided by 438.

On to step 1:
The number 438 fits into 8 0 times, leaving a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Take the next digit (1) from the dividend and append it to 8, then repeat: 81 / 438

On to step 2:
When dividing 81 by 438, we get 0 with a remainder of 81.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 81 after subtracting 0 from 81.
Append the next digit (7) from the dividend to 81 and continue with: 817 / 438

Let's proceed to step 3:
817 divided by 438 is 1 with a remainder of 379.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 438 from 817, we get 379.
Include the next digit (8) from the dividend after 379, then repeat: 3798 / 438

Going ahead to step 4:
When dividing 3798 by 438, we get 8 with a remainder of 294.
The number 8 becomes the next digit in our result. 
Result so far: 18.0
Subtracting 3504 from 3798 leaves us with 294.
Take the next digit (2) from the dividend and append it to 294, then repeat: 2942 / 438

Step 5:
438 can be fit into 2942 6 times, resulting in a remainder of 314.
Record the quotient 6 as the next digit in the result. 
Result so far: 186.0
Subtract 2628 from 2942 to get 314.
Grab the next digit (0) from the dividend, add it to 314, then carry on: 3140 / 438

Let's proceed to step 6:
The number 438 fits into 3140 7 times, leaving a remainder of 74.
The number 7 becomes the next digit in our result. 
Result so far: 1867.0
The remainder is 74 after subtracting 3066 from 3140.
Take the next digit (3) from the dividend and append it to 74, then repeat: 743 / 438

Going ahead to step 7:
The number 438 fits into 743 1 times, leaving a remainder of 305.
Use 1 as the next digit of our solution. 
Result so far: 18671.0
Subtracting 438 from 743 leaves us with 305.
Append the next digit (2) from the dividend to 305 and continue with: 3052 / 438

Step 8:
The number 438 fits into 3052 6 times, leaving a remainder of 424.
The next digit of our result is 6. 
Result so far: 186716.0
If we take 2628 away from 3052, we end up with 424.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4240, and continue the process.

Going ahead to step 9:
4240 divided by 438 is 9 with a remainder of 298.
Use 9 as the next digit of our solution. 
Result so far: 186716.9
Deduct 3942 from 4240 and we're left with 298.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2980, and continue the process.

Moving on to step 10:
2980 divided by 438 is 6 with a remainder of 352.
Write down 6 as next digit of the result. 
Result so far: 186716.96
If we take 2628 away from 2980, we end up with 352.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

Let's proceed to step 11:
438 can be fit into 3520 8 times, resulting in a remainder of 16.
Write down 8 as next digit of the result. 
Result so far: 186716.968
Subtracting 3504 from 3520 leaves us 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.

Let's proceed to step 12:
The number 438 fits into 160 0 times, leaving a remainder of 160.
The next digit of our result is 0. 
Result so far: 186716.968
Subtracting 0 from 160 leaves us with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Going ahead to step 13:
The number 438 fits into 1600 3 times, leaving a remainder of 286.
The next digit of our result is 3. 
Result so far: 186716.96803
Deduct 1314 from 1600 and we're left with 286.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2860, and continue the process.

Advancing to step 14:
438 can be fit into 2860 6 times, resulting in a remainder of 232.
The number 6 becomes the next digit in our result. 
Result so far: 186716.968036
Subtract 2628 from 2860 to get 232.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2320, and continue the process.

Moving on to step 15:
If we divide 2320 by 438, we get 5 and a remainder of 130.
Put 5 as the next digit of the answer. 
Result so far: 186716.9680365
Subtract 2190 from 2320 to get 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Going ahead to step 16:
If we divide 1300 by 438, we get 2 and a remainder of 424.
Use 2 as the next digit of our solution. 
Result so far: 186716.96803652
Subtracting 876 from 1300 leaves us with 424.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4240, and continue the process.

In conclusion, the division gives 186716.96803652 with a balance of 4.24e-07.
