81516089 divided by 755 
Our goal is to divide 81516089 by 755.

On to step 1:
If we divide 8 by 755, we get 0 and a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Grab the next digit (1) from the dividend, add it to 8, then carry on: 81 / 755

Let's proceed to step 2:
If we divide 81 by 755, we get 0 and a remainder of 81.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 81 to get 81.
Take the next digit (5) from the dividend and append it to 81, then repeat: 815 / 755

Advancing to step 3:
755 goes into 815 1 times with a remainder of 60.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 755 from 815 and we're left with 60.
Grab the next digit (1) from the dividend, add it to 60, then carry on: 601 / 755

Step 4:
When dividing 601 by 755, we get 0 with a remainder of 601.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
Subtract 0 from 601 to get 601.
Append the next digit (6) from the dividend to 601 and continue with: 6016 / 755

Going ahead to step 5:
755 can be fit into 6016 7 times, resulting in a remainder of 731.
The number 7 becomes the next digit in our result. 
Result so far: 107.0
The remainder is 731 after subtracting 5285 from 6016.
Include the next digit (0) from the dividend after 731, then repeat: 7310 / 755

Advancing to step 6:
If we divide 7310 by 755, we get 9 and a remainder of 515.
The next digit of our result is 9. 
Result so far: 1079.0
Subtract 6795 from 7310 to get 515.
Take the next digit (8) from the dividend and append it to 515, then repeat: 5158 / 755

On to step 7:
When dividing 5158 by 755, we get 6 with a remainder of 628.
Write down 6 as next digit of the result. 
Result so far: 10796.0
The remainder is 628 after subtracting 4530 from 5158.
Bring next digit (9) of the dividend behind the 628 and repeat the process: 6289 / 755

Advancing to step 8:
If we divide 6289 by 755, we get 8 and a remainder of 249.
Record the quotient 8 as the next digit in the result. 
Result so far: 107968.0
If we take 6040 away from 6289, we end up with 249.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2490, and continue the process.

On to step 9:
2490 divided by 755 is 3 with a remainder of 225.
The next digit of our result is 3. 
Result so far: 107968.3
The remainder is 225 after subtracting 2265 from 2490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2250, and continue the process.

Advancing to step 10:
755 goes into 2250 2 times with a remainder of 740.
The number 2 becomes the next digit in our result. 
Result so far: 107968.32
Subtracting 1510 from 2250 leaves us with 740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7400, and continue the process.

On to step 11:
The number 755 fits into 7400 9 times, leaving a remainder of 605.
The next digit of our result is 9. 
Result so far: 107968.329
Deduct 6795 from 7400 and we're left with 605.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6050, and continue the process.

Moving on to step 12:
755 goes into 6050 8 times with a remainder of 10.
Put 8 as the next digit of the answer. 
Result so far: 107968.3298
If we take 6040 away from 6050, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 13:
755 goes into 100 0 times with a remainder of 100.
Put 0 as the next digit of the answer. 
Result so far: 107968.3298
Subtract 0 from 100 to get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Advancing to step 14:
The number 755 fits into 1000 1 times, leaving a remainder of 245.
The number 1 becomes the next digit in our result. 
Result so far: 107968.329801
The remainder is 245 after subtracting 755 from 1000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2450, and continue the process.

On to step 15:
If we divide 2450 by 755, we get 3 and a remainder of 185.
Write down 3 as next digit of the result. 
Result so far: 107968.3298013
The remainder is 185 after subtracting 2265 from 2450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1850, and continue the process.

Step 16:
755 goes into 1850 2 times with a remainder of 340.
The next digit of our result is 2. 
Result so far: 107968.32980132
The remainder is 340 after subtracting 1510 from 1850.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

The final outcome is 107968.32980132, with a leftover of 3.4e-07.
