Let's divide 81316893 by 316
We want to figure out the number of times 81316893 can be divided by 316.

Advancing to step 1:
8 divided by 316 is 0 with 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.
Grab the next digit (1) from the dividend, add it to 8, then carry on: 81 / 316

Advancing to step 2:
316 goes into 81 0 times with a remainder of 81.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 81 leaves us with 81.
Append the next digit (3) from the dividend to 81 and continue with: 813 / 316

Let's proceed to step 3:
If we divide 813 by 316, we get 2 and a remainder of 181.
Use 2 as the next digit of our solution. 
Result so far: 2.0
The remainder is 181 after subtracting 632 from 813.
Grab the next digit (1) from the dividend, add it to 181, then carry on: 1811 / 316

Going ahead to step 4:
When dividing 1811 by 316, we get 5 with a remainder of 231.
Use 5 as the next digit of our solution. 
Result so far: 25.0
The remainder is 231 after subtracting 1580 from 1811.
Append the next digit (6) from the dividend to 231 and continue with: 2316 / 316

Moving on to step 5:
If we divide 2316 by 316, we get 7 and a remainder of 104.
Put 7 as the next digit of the answer. 
Result so far: 257.0
Subtracting 2212 from 2316 leaves us with 104.
Take the next digit (8) from the dividend and append it to 104, then repeat: 1048 / 316

Step 6:
316 goes into 1048 3 times with a remainder of 100.
Put 3 as the next digit of the answer. 
Result so far: 2573.0
If we take 948 away from 1048, we end up with 100.
Grab the next digit (9) from the dividend, add it to 100, then carry on: 1009 / 316

Advancing to step 7:
When dividing 1009 by 316, we get 3 with a remainder of 61.
Record the quotient 3 as the next digit in the result. 
Result so far: 25733.0
Subtracting 948 from 1009 leaves us with 61.
Take the next digit (3) from the dividend and append it to 61, then repeat: 613 / 316

Moving on to step 8:
The number 316 fits into 613 1 times, leaving a remainder of 297.
The number 1 becomes the next digit in our result. 
Result so far: 257331.0
If we subtract 316 from 613, we get 297.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2970, and continue the process.

Moving on to step 9:
When dividing 2970 by 316, we get 9 with a remainder of 126.
Put 9 as the next digit of the answer. 
Result so far: 257331.9
Subtract 2844 from 2970 to get 126.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

On to step 10:
When dividing 1260 by 316, we get 3 with a remainder of 312.
Put 3 as the next digit of the answer. 
Result so far: 257331.93
Subtracting 948 from 1260 leaves us with 312.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3120, and continue the process.

Step 11:
316 goes into 3120 9 times with a remainder of 276.
Use 9 as the next digit of our solution. 
Result so far: 257331.939
If we take 2844 away from 3120, we end up with 276.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2760, and continue the process.

Moving on to step 12:
When dividing 2760 by 316, we get 8 with a remainder of 232.
Put 8 as the next digit of the answer. 
Result so far: 257331.9398
Deduct 2528 from 2760 and we're left with 232.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2320, and continue the process.

Going ahead to step 13:
If we divide 2320 by 316, we get 7 and a remainder of 108.
The number 7 becomes the next digit in our result. 
Result so far: 257331.93987
Deduct 2212 from 2320 and we're left with 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Going ahead to step 14:
316 can be fit into 1080 3 times, resulting in a remainder of 132.
The next digit of our result is 3. 
Result so far: 257331.939873
Subtracting 948 from 1080 leaves us with 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

Going ahead to step 15:
1320 divided by 316 is 4 with a remainder of 56.
Record the quotient 4 as the next digit in the result. 
Result so far: 257331.9398734
If we take 1264 away from 1320, we end up with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

On to step 16:
When dividing 560 by 316, we get 1 with a remainder of 244.
Write down 1 as next digit of the result. 
Result so far: 257331.93987341
If we take 316 away from 560, we end up with 244.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2440, and continue the process.

Our division results in 257331.93987341 with a remaining 2.44e-07.
