42080925 divided by 770 
We want to figure out the number of times 42080925 can be divided by 770.

Step 1:
770 can be fit into 4 0 times, resulting in a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Include the next digit (2) from the dividend after 4, then repeat: 42 / 770

Going ahead to step 2:
770 can be fit into 42 0 times, resulting in a remainder of 42.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 42 leaves us with 42.
Take the next digit (0) from the dividend and append it to 42, then repeat: 420 / 770

Step 3:
420 divided by 770 is 0 with a remainder of 420.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 420 leaves us with 420.
Grab the next digit (8) from the dividend, add it to 420, then carry on: 4208 / 770

On to step 4:
770 can be fit into 4208 5 times, resulting in a remainder of 358.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
Subtract 3850 from 4208 to get 358.
Fetch the next digit (0) from the dividend, attach it to 358 and continue: 3580 / 770

On to step 5:
770 goes into 3580 4 times with a remainder of 500.
The next digit of our result is 4. 
Result so far: 54.0
Deduct 3080 from 3580 and we're left with 500.
Bring next digit (9) of the dividend behind the 500 and repeat the process: 5009 / 770

Going ahead to step 6:
770 can be fit into 5009 6 times, resulting in a remainder of 389.
Record the quotient 6 as the next digit in the result. 
Result so far: 546.0
The remainder is 389 after subtracting 4620 from 5009.
Take the next digit (2) from the dividend and append it to 389, then repeat: 3892 / 770

Moving on to step 7:
3892 divided by 770 is 5 with a remainder of 42.
The next digit of our result is 5. 
Result so far: 5465.0
Subtract 3850 from 3892 to get 42.
Grab the next digit (5) from the dividend, add it to 42, then carry on: 425 / 770

Going ahead to step 8:
The number 770 fits into 425 0 times, leaving a remainder of 425.
The next digit of our result is 0. 
Result so far: 54650.0
Deduct 0 from 425 and we're left with 425.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4250, and continue the process.

Advancing to step 9:
The number 770 fits into 4250 5 times, leaving a remainder of 400.
Record the quotient 5 as the next digit in the result. 
Result so far: 54650.5
If we subtract 3850 from 4250, we 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.

Going ahead to step 10:
When dividing 4000 by 770, we get 5 with a remainder of 150.
Put 5 as the next digit of the answer. 
Result so far: 54650.55
If we take 3850 away from 4000, we end up with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

The quotient of the division is 54650.55, and the remainder is 0.15.
