We're dividing 81581295 by 351 
We want to figure out the number of times 81581295 can be divided by 351.

Moving on to step 1:
351 goes into 8 0 times with a remainder of 8.
Write down 0 as next digit of the result. 
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 / 351

Advancing to step 2:
When dividing 81 by 351, we get 0 with a remainder of 81.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 81 after subtracting 0 from 81.
Grab the next digit (5) from the dividend, add it to 81, then carry on: 815 / 351

Advancing to step 3:
351 can be fit into 815 2 times, resulting in a remainder of 113.
The next digit of our result is 2. 
Result so far: 2.0
If we subtract 702 from 815, we get 113.
Take the next digit (8) from the dividend and append it to 113, then repeat: 1138 / 351

On to step 4:
351 can be fit into 1138 3 times, resulting in a remainder of 85.
Record the quotient 3 as the next digit in the result. 
Result so far: 23.0
Deduct 1053 from 1138 and we're left with 85.
Include the next digit (1) from the dividend after 85, then repeat: 851 / 351

Let's proceed to step 5:
If we divide 851 by 351, we get 2 and a remainder of 149.
Use 2 as the next digit of our solution. 
Result so far: 232.0
Subtract 702 from 851 to get 149.
Grab the next digit (2) from the dividend, add it to 149, then carry on: 1492 / 351

Let's proceed to step 6:
351 goes into 1492 4 times with a remainder of 88.
Put 4 as the next digit of the answer. 
Result so far: 2324.0
Subtracting 1404 from 1492 leaves us with 88.
Take the next digit (9) from the dividend and append it to 88, then repeat: 889 / 351

Advancing to step 7:
889 divided by 351 is 2 with a remainder of 187.
Write down 2 as next digit of the result. 
Result so far: 23242.0
If we take 702 away from 889, we end up with 187.
Append the next digit (5) from the dividend to 187 and continue with: 1875 / 351

On to step 8:
When dividing 1875 by 351, we get 5 with a remainder of 120.
Write down 5 as next digit of the result. 
Result so far: 232425.0
If we take 1755 away from 1875, we end up with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Step 9:
When dividing 1200 by 351, we get 3 with a remainder of 147.
The number 3 becomes the next digit in our result. 
Result so far: 232425.3
The remainder is 147 after subtracting 1053 from 1200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1470, and continue the process.

On to step 10:
When dividing 1470 by 351, we get 4 with a remainder of 66.
Record the quotient 4 as the next digit in the result. 
Result so far: 232425.34
Deduct 1404 from 1470 and we're left with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Going ahead to step 11:
The number 351 fits into 660 1 times, leaving a remainder of 309.
Use 1 as the next digit of our solution. 
Result so far: 232425.341
Subtracting 351 from 660 leaves us with 309.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3090, and continue the process.

On to step 12:
351 can be fit into 3090 8 times, resulting in a remainder of 282.
The number 8 becomes the next digit in our result. 
Result so far: 232425.3418
If we subtract 2808 from 3090, we get 282.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2820, and continue the process.

Step 13:
When dividing 2820 by 351, we get 8 with a remainder of 12.
Use 8 as the next digit of our solution. 
Result so far: 232425.34188
Subtract 2808 from 2820 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Our division results in 232425.34188 with a remaining 1.2e-05.
