We're dividing 51205534 by 771 
We're looking to find how many times 771 goes into 51205534.

Step 1:
771 goes into 5 0 times with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Include the next digit (1) from the dividend after 5, then repeat: 51 / 771

Advancing to step 2:
If we divide 51 by 771, we get 0 and a remainder of 51.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 51 after subtracting 0 from 51.
Bring next digit (2) of the dividend behind the 51 and repeat the process: 512 / 771

On to step 3:
771 goes into 512 0 times with a remainder of 512.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 512 to get 512.
Take the next digit (0) from the dividend and append it to 512, then repeat: 5120 / 771

Going ahead to step 4:
771 can be fit into 5120 6 times, resulting in a remainder of 494.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
The remainder is 494 after subtracting 4626 from 5120.
Append the next digit (5) from the dividend to 494 and continue with: 4945 / 771

Advancing to step 5:
If we divide 4945 by 771, we get 6 and a remainder of 319.
Use 6 as the next digit of our solution. 
Result so far: 66.0
Subtracting 4626 from 4945 leaves us with 319.
Grab the next digit (5) from the dividend, add it to 319, then carry on: 3195 / 771

Advancing to step 6:
771 can be fit into 3195 4 times, resulting in a remainder of 111.
Write down 4 as next digit of the result. 
Result so far: 664.0
Subtracting 3084 from 3195 leaves us with 111.
Fetch the next digit (3) from the dividend, attach it to 111 and continue: 1113 / 771

Step 7:
771 can be fit into 1113 1 times, resulting in a remainder of 342.
The next digit of our result is 1. 
Result so far: 6641.0
If we subtract 771 from 1113, we get 342.
Include the next digit (4) from the dividend after 342, then repeat: 3424 / 771

On to step 8:
When dividing 3424 by 771, we get 4 with a remainder of 340.
Record the quotient 4 as the next digit in the result. 
Result so far: 66414.0
The remainder is 340 after subtracting 3084 from 3424.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Advancing to step 9:
When dividing 3400 by 771, we get 4 with a remainder of 316.
Put 4 as the next digit of the answer. 
Result so far: 66414.4
The remainder is 316 after subtracting 3084 from 3400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3160, and continue the process.

Advancing to step 10:
The number 771 fits into 3160 4 times, leaving a remainder of 76.
The number 4 becomes the next digit in our result. 
Result so far: 66414.44
Deduct 3084 from 3160 and we're left with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

After the division, we end up with 66414.44 and a remainder of 0.076.
