We look at the division of 3131384 by 776 
Our goal is to divide 3131384 by 776.

On to step 1:
The number 776 fits into 3 0 times, leaving a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Append the next digit (1) from the dividend to 3 and continue with: 31 / 776

Step 2:
31 divided by 776 is 0 with a remainder of 31.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 31, we get 31.
Bring next digit (3) of the dividend behind the 31 and repeat the process: 313 / 776

Step 3:
313 divided by 776 is 0 with a remainder of 313.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 313 to get 313.
Include the next digit (1) from the dividend after 313, then repeat: 3131 / 776

Going ahead to step 4:
If we divide 3131 by 776, we get 4 and a remainder of 27.
Write down 4 as next digit of the result. 
Result so far: 4.0
If we subtract 3104 from 3131, we get 27.
Fetch the next digit (3) from the dividend, attach it to 27 and continue: 273 / 776

Advancing to step 5:
When dividing 273 by 776, we get 0 with a remainder of 273.
The next digit of our result is 0. 
Result so far: 40.0
Deduct 0 from 273 and we're left with 273.
Fetch the next digit (8) from the dividend, attach it to 273 and continue: 2738 / 776

Going ahead to step 6:
If we divide 2738 by 776, we get 3 and a remainder of 410.
Put 3 as the next digit of the answer. 
Result so far: 403.0
If we take 2328 away from 2738, we end up with 410.
Include the next digit (4) from the dividend after 410, then repeat: 4104 / 776

Going ahead to step 7:
776 can be fit into 4104 5 times, resulting in a remainder of 224.
The number 5 becomes the next digit in our result. 
Result so far: 4035.0
The remainder is 224 after subtracting 3880 from 4104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

Advancing to step 8:
The number 776 fits into 2240 2 times, leaving a remainder of 688.
Record the quotient 2 as the next digit in the result. 
Result so far: 4035.2
Deduct 1552 from 2240 and we're left with 688.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6880, and continue the process.

Advancing to step 9:
If we divide 6880 by 776, we get 8 and a remainder of 672.
The number 8 becomes the next digit in our result. 
Result so far: 4035.28
If we subtract 6208 from 6880, we get 672.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6720, and continue the process.

Going ahead to step 10:
776 goes into 6720 8 times with a remainder of 512.
The number 8 becomes the next digit in our result. 
Result so far: 4035.288
If we subtract 6208 from 6720, we get 512.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5120, and continue the process.

The final result is 4035.288 with a remainder of 0.0512.
