81328691 divided by 437 
We're looking to find how many times 437 goes into 81328691.

On to step 1:
When dividing 8 by 437, we get 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Include the next digit (1) from the dividend after 8, then repeat: 81 / 437

Going ahead to step 2:
If we divide 81 by 437, we get 0 and a remainder of 81.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 81 and we're left with 81.
Bring next digit (3) of the dividend behind the 81 and repeat the process: 813 / 437

Moving on to step 3:
When dividing 813 by 437, we get 1 with a remainder of 376.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 376 after subtracting 437 from 813.
Fetch the next digit (2) from the dividend, attach it to 376 and continue: 3762 / 437

Going ahead to step 4:
3762 divided by 437 is 8 with a remainder of 266.
The next digit of our result is 8. 
Result so far: 18.0
Subtracting 3496 from 3762 leaves us with 266.
Bring next digit (8) of the dividend behind the 266 and repeat the process: 2668 / 437

Step 5:
437 goes into 2668 6 times with a remainder of 46.
The number 6 becomes the next digit in our result. 
Result so far: 186.0
The remainder is 46 after subtracting 2622 from 2668.
Grab the next digit (6) from the dividend, add it to 46, then carry on: 466 / 437

Advancing to step 6:
437 goes into 466 1 times with a remainder of 29.
The number 1 becomes the next digit in our result. 
Result so far: 1861.0
If we subtract 437 from 466, we get 29.
Include the next digit (9) from the dividend after 29, then repeat: 299 / 437

Going ahead to step 7:
When dividing 299 by 437, we get 0 with a remainder of 299.
Put 0 as the next digit of the answer. 
Result so far: 18610.0
Subtracting 0 from 299 leaves us with 299.
Take the next digit (1) from the dividend and append it to 299, then repeat: 2991 / 437

Advancing to step 8:
The number 437 fits into 2991 6 times, leaving a remainder of 369.
The next digit of our result is 6. 
Result so far: 186106.0
Subtract 2622 from 2991 to get 369.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3690, and continue the process.

Let's proceed to step 9:
437 goes into 3690 8 times with a remainder of 194.
Record the quotient 8 as the next digit in the result. 
Result so far: 186106.8
Subtract 3496 from 3690 to get 194.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1940, and continue the process.

Advancing to step 10:
The number 437 fits into 1940 4 times, leaving a remainder of 192.
Record the quotient 4 as the next digit in the result. 
Result so far: 186106.84
If we take 1748 away from 1940, we end up with 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

On to step 11:
1920 divided by 437 is 4 with a remainder of 172.
Put 4 as the next digit of the answer. 
Result so far: 186106.844
If we subtract 1748 from 1920, we get 172.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

Our division results in 186106.844 with a remaining 0.0172.
