We look at the division of 51377933 by 770 
Let's see how many times 770 fits into 51377933.

On to step 1:
When dividing 5 by 770, we get 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Append the next digit (1) from the dividend to 5 and continue with: 51 / 770

Advancing to step 2:
770 goes into 51 0 times with a remainder of 51.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 51 after subtracting 0 from 51.
Append the next digit (3) from the dividend to 51 and continue with: 513 / 770

Moving on to step 3:
770 can be fit into 513 0 times, resulting in a remainder of 513.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 513 and we're left with 513.
Grab the next digit (7) from the dividend, add it to 513, then carry on: 5137 / 770

Going ahead to step 4:
The number 770 fits into 5137 6 times, leaving a remainder of 517.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
Subtract 4620 from 5137 to get 517.
Fetch the next digit (7) from the dividend, attach it to 517 and continue: 5177 / 770

Advancing to step 5:
The number 770 fits into 5177 6 times, leaving a remainder of 557.
Use 6 as the next digit of our solution. 
Result so far: 66.0
The remainder is 557 after subtracting 4620 from 5177.
Bring next digit (9) of the dividend behind the 557 and repeat the process: 5579 / 770

Moving on to step 6:
If we divide 5579 by 770, we get 7 and a remainder of 189.
The number 7 becomes the next digit in our result. 
Result so far: 667.0
Subtracting 5390 from 5579 leaves us with 189.
Fetch the next digit (3) from the dividend, attach it to 189 and continue: 1893 / 770

Moving on to step 7:
770 can be fit into 1893 2 times, resulting in a remainder of 353.
The next digit of our result is 2. 
Result so far: 6672.0
Deduct 1540 from 1893 and we're left with 353.
Fetch the next digit (3) from the dividend, attach it to 353 and continue: 3533 / 770

Advancing to step 8:
3533 divided by 770 is 4 with a remainder of 453.
Record the quotient 4 as the next digit in the result. 
Result so far: 66724.0
Deduct 3080 from 3533 and we're left with 453.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4530, and continue the process.

On to step 9:
If we divide 4530 by 770, we get 5 and a remainder of 680.
The next digit of our result is 5. 
Result so far: 66724.5
Subtract 3850 from 4530 to get 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6800, and continue the process.

Moving on to step 10:
6800 divided by 770 is 8 with a remainder of 640.
The next digit of our result is 8. 
Result so far: 66724.58
Deduct 6160 from 6800 and we're left with 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

Moving on to step 11:
770 can be fit into 6400 8 times, resulting in a remainder of 240.
The next digit of our result is 8. 
Result so far: 66724.588
Deduct 6160 from 6400 and we're left with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

The final result is 66724.588 with a remainder of 0.024.
