Let's divide 3187312 by 755
We're looking to find how many times 755 goes into 3187312.

Going ahead to step 1:
If we divide 3 by 755, we get 0 and a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Append the next digit (1) from the dividend to 3 and continue with: 31 / 755

Step 2:
When dividing 31 by 755, we get 0 with a remainder of 31.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 31 leaves us with 31.
Grab the next digit (8) from the dividend, add it to 31, then carry on: 318 / 755

Moving on to step 3:
The number 755 fits into 318 0 times, leaving a remainder of 318.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 318 leaves us with 318.
Include the next digit (7) from the dividend after 318, then repeat: 3187 / 755

On to step 4:
If we divide 3187 by 755, we get 4 and a remainder of 167.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Subtract 3020 from 3187 to get 167.
Append the next digit (3) from the dividend to 167 and continue with: 1673 / 755

Step 5:
755 goes into 1673 2 times with a remainder of 163.
The next digit of our result is 2. 
Result so far: 42.0
Subtract 1510 from 1673 to get 163.
Append the next digit (1) from the dividend to 163 and continue with: 1631 / 755

On to step 6:
755 can be fit into 1631 2 times, resulting in a remainder of 121.
The next digit of our result is 2. 
Result so far: 422.0
If we subtract 1510 from 1631, we get 121.
Append the next digit (2) from the dividend to 121 and continue with: 1212 / 755

Advancing to step 7:
If we divide 1212 by 755, we get 1 and a remainder of 457.
Put 1 as the next digit of the answer. 
Result so far: 4221.0
Subtract 755 from 1212 to get 457.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4570, and continue the process.

Going ahead to step 8:
755 can be fit into 4570 6 times, resulting in a remainder of 40.
Record the quotient 6 as the next digit in the result. 
Result so far: 4221.6
Subtracting 4530 from 4570 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 9:
755 can be fit into 400 0 times, resulting in a remainder of 400.
Put 0 as the next digit of the answer. 
Result so far: 4221.6
Subtract 0 from 400 to get 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

On to step 10:
755 goes into 4000 5 times with a remainder of 225.
Use 5 as the next digit of our solution. 
Result so far: 4221.605
Subtracting 3775 from 4000 leaves us with 225.
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 11:
755 goes into 2250 2 times with a remainder of 740.
The next digit of our result is 2. 
Result so far: 4221.6052
If we subtract 1510 from 2250, we get 740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7400, and continue the process.

Going ahead to step 12:
The number 755 fits into 7400 9 times, leaving a remainder of 605.
The number 9 becomes the next digit in our result. 
Result so far: 4221.60529
Subtracting 6795 from 7400 leaves us 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.

Going ahead to step 13:
755 goes into 6050 8 times with a remainder of 10.
Use 8 as the next digit of our solution. 
Result so far: 4221.605298
Subtracting 6040 from 6050 leaves us 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.

Let's proceed to step 14:
100 divided by 755 is 0 with a remainder of 100.
The next digit of our result is 0. 
Result so far: 4221.605298
If we subtract 0 from 100, we 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.

On to step 15:
When dividing 1000 by 755, we get 1 with a remainder of 245.
Record the quotient 1 as the next digit in the result. 
Result so far: 4221.60529801
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.

The final outcome is 4221.60529801, with a leftover of 2.45e-07.
