42753815 ÷ 770 
Our goal is to divide 42753815 by 770.

Step 1:
770 can be fit into 4 0 times, resulting in a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Take the next digit (2) from the dividend and append it to 4, then repeat: 42 / 770

On to step 2:
770 can be fit into 42 0 times, resulting in a remainder of 42.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 42, we get 42.
Take the next digit (7) from the dividend and append it to 42, then repeat: 427 / 770

Going ahead to step 3:
When dividing 427 by 770, we get 0 with a remainder of 427.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 427 after subtracting 0 from 427.
Append the next digit (5) from the dividend to 427 and continue with: 4275 / 770

Step 4:
When dividing 4275 by 770, we get 5 with a remainder of 425.
Put 5 as the next digit of the answer. 
Result so far: 5.0
Subtract 3850 from 4275 to get 425.
Include the next digit (3) from the dividend after 425, then repeat: 4253 / 770

Let's proceed to step 5:
The number 770 fits into 4253 5 times, leaving a remainder of 403.
The number 5 becomes the next digit in our result. 
Result so far: 55.0
Subtract 3850 from 4253 to get 403.
Append the next digit (8) from the dividend to 403 and continue with: 4038 / 770

On to step 6:
4038 divided by 770 is 5 with a remainder of 188.
Record the quotient 5 as the next digit in the result. 
Result so far: 555.0
If we take 3850 away from 4038, we end up with 188.
Bring next digit (1) of the dividend behind the 188 and repeat the process: 1881 / 770

Advancing to step 7:
When dividing 1881 by 770, we get 2 with a remainder of 341.
Write down 2 as next digit of the result. 
Result so far: 5552.0
If we subtract 1540 from 1881, we get 341.
Bring next digit (5) of the dividend behind the 341 and repeat the process: 3415 / 770

On to step 8:
770 goes into 3415 4 times with a remainder of 335.
The next digit of our result is 4. 
Result so far: 55524.0
Deduct 3080 from 3415 and we're left with 335.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3350, and continue the process.

On to step 9:
If we divide 3350 by 770, we get 4 and a remainder of 270.
The next digit of our result is 4. 
Result so far: 55524.4
Subtracting 3080 from 3350 leaves us with 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

Step 10:
2700 divided by 770 is 3 with a remainder of 390.
Use 3 as the next digit of our solution. 
Result so far: 55524.43
The remainder is 390 after subtracting 2310 from 2700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3900, and continue the process.

Step 11:
770 goes into 3900 5 times with a remainder of 50.
Put 5 as the next digit of the answer. 
Result so far: 55524.435
Subtracting 3850 from 3900 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 12:
770 goes into 500 0 times with a remainder of 500.
The next digit of our result is 0. 
Result so far: 55524.435
Subtracting 0 from 500 leaves us with 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

Step 13:
770 can be fit into 5000 6 times, resulting in a remainder of 380.
The next digit of our result is 6. 
Result so far: 55524.43506
Deduct 4620 from 5000 and we're left with 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Step 14:
770 can be fit into 3800 4 times, resulting in a remainder of 720.
The number 4 becomes the next digit in our result. 
Result so far: 55524.435064
Subtract 3080 from 3800 to get 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7200, and continue the process.

On to step 15:
770 goes into 7200 9 times with a remainder of 270.
Record the quotient 9 as the next digit in the result. 
Result so far: 55524.4350649
Subtracting 6930 from 7200 leaves us with 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

Let's proceed to step 16:
The number 770 fits into 2700 3 times, leaving a remainder of 390.
Write down 3 as next digit of the result. 
Result so far: 55524.43506493
The remainder is 390 after subtracting 2310 from 2700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3900, and continue the process.

The quotient of the division is 55524.43506493, and the remainder is 3.9e-07.
