42480028 ÷ 771 
Our goal is to divide 42480028 by 771.

Moving on to step 1:
If we divide 4 by 771, we get 0 and a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Append the next digit (2) from the dividend to 4 and continue with: 42 / 771

Let's proceed to step 2:
If we divide 42 by 771, we get 0 and a remainder of 42.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 42 after subtracting 0 from 42.
Grab the next digit (4) from the dividend, add it to 42, then carry on: 424 / 771

Step 3:
When dividing 424 by 771, we get 0 with a remainder of 424.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 424 and we're left with 424.
Take the next digit (8) from the dividend and append it to 424, then repeat: 4248 / 771

Moving on to step 4:
If we divide 4248 by 771, we get 5 and a remainder of 393.
Use 5 as the next digit of our solution. 
Result so far: 5.0
The remainder is 393 after subtracting 3855 from 4248.
Include the next digit (0) from the dividend after 393, then repeat: 3930 / 771

Advancing to step 5:
771 goes into 3930 5 times with a remainder of 75.
Use 5 as the next digit of our solution. 
Result so far: 55.0
Subtracting 3855 from 3930 leaves us with 75.
Include the next digit (0) from the dividend after 75, then repeat: 750 / 771

Moving on to step 6:
771 goes into 750 0 times with a remainder of 750.
The number 0 becomes the next digit in our result. 
Result so far: 550.0
If we take 0 away from 750, we end up with 750.
Bring next digit (2) of the dividend behind the 750 and repeat the process: 7502 / 771

On to step 7:
If we divide 7502 by 771, we get 9 and a remainder of 563.
Write down 9 as next digit of the result. 
Result so far: 5509.0
If we take 6939 away from 7502, we end up with 563.
Grab the next digit (8) from the dividend, add it to 563, then carry on: 5638 / 771

Moving on to step 8:
If we divide 5638 by 771, we get 7 and a remainder of 241.
Record the quotient 7 as the next digit in the result. 
Result so far: 55097.0
If we subtract 5397 from 5638, we get 241.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2410, and continue the process.

Let's proceed to step 9:
2410 divided by 771 is 3 with a remainder of 97.
Write down 3 as next digit of the result. 
Result so far: 55097.3
Subtracting 2313 from 2410 leaves us with 97.
Since there are no more digits in the dividend, we add a zero to the remainder making it 970, and continue the process.

Let's proceed to step 10:
771 goes into 970 1 times with a remainder of 199.
Record the quotient 1 as the next digit in the result. 
Result so far: 55097.31
If we subtract 771 from 970, we get 199.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1990, and continue the process.

Step 11:
771 goes into 1990 2 times with a remainder of 448.
Put 2 as the next digit of the answer. 
Result so far: 55097.312
The remainder is 448 after subtracting 1542 from 1990.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4480, and continue the process.

Advancing to step 12:
The number 771 fits into 4480 5 times, leaving a remainder of 625.
Record the quotient 5 as the next digit in the result. 
Result so far: 55097.3125
If we subtract 3855 from 4480, we get 625.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6250, and continue the process.

Let's proceed to step 13:
If we divide 6250 by 771, we get 8 and a remainder of 82.
Record the quotient 8 as the next digit in the result. 
Result so far: 55097.31258
If we subtract 6168 from 6250, we get 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Moving on to step 14:
771 can be fit into 820 1 times, resulting in a remainder of 49.
The next digit of our result is 1. 
Result so far: 55097.312581
The remainder is 49 after subtracting 771 from 820.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

On to step 15:
If we divide 490 by 771, we get 0 and a remainder of 490.
The number 0 becomes the next digit in our result. 
Result so far: 55097.312581
Deduct 0 from 490 and we're left with 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4900, and continue the process.

On to step 16:
771 can be fit into 4900 6 times, resulting in a remainder of 274.
Put 6 as the next digit of the answer. 
Result so far: 55097.31258106
The remainder is 274 after subtracting 4626 from 4900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2740, and continue the process.

After the division, we end up with 55097.31258106 and a remainder of 2.74e-07.
