42239650 divided by 770 
Our goal is to divide 42239650 by 770.

Going ahead to step 1:
770 goes into 4 0 times with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Include the next digit (2) from the dividend after 4, then repeat: 42 / 770

Moving on to step 2:
The number 770 fits into 42 0 times, leaving a remainder of 42.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 42 leaves us with 42.
Grab the next digit (2) from the dividend, add it to 42, then carry on: 422 / 770

On to step 3:
770 can be fit into 422 0 times, resulting in a remainder of 422.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 422 leaves us with 422.
Take the next digit (3) from the dividend and append it to 422, then repeat: 4223 / 770

Moving on to step 4:
If we divide 4223 by 770, we get 5 and a remainder of 373.
Write down 5 as next digit of the result. 
Result so far: 5.0
Subtracting 3850 from 4223 leaves us with 373.
Include the next digit (9) from the dividend after 373, then repeat: 3739 / 770

Let's proceed to step 5:
770 can be fit into 3739 4 times, resulting in a remainder of 659.
Use 4 as the next digit of our solution. 
Result so far: 54.0
The remainder is 659 after subtracting 3080 from 3739.
Grab the next digit (6) from the dividend, add it to 659, then carry on: 6596 / 770

Step 6:
The number 770 fits into 6596 8 times, leaving a remainder of 436.
The next digit of our result is 8. 
Result so far: 548.0
Deduct 6160 from 6596 and we're left with 436.
Fetch the next digit (5) from the dividend, attach it to 436 and continue: 4365 / 770

Going ahead to step 7:
4365 divided by 770 is 5 with a remainder of 515.
Use 5 as the next digit of our solution. 
Result so far: 5485.0
Subtracting 3850 from 4365 leaves us with 515.
Append the next digit (0) from the dividend to 515 and continue with: 5150 / 770

Let's proceed to step 8:
The number 770 fits into 5150 6 times, leaving a remainder of 530.
The number 6 becomes the next digit in our result. 
Result so far: 54856.0
If we subtract 4620 from 5150, we get 530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5300, and continue the process.

Step 9:
770 can be fit into 5300 6 times, resulting in a remainder of 680.
The number 6 becomes the next digit in our result. 
Result so far: 54856.6
If we subtract 4620 from 5300, we 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.

Let's proceed to step 10:
When dividing 6800 by 770, we get 8 with a remainder of 640.
Put 8 as the next digit of the answer. 
Result so far: 54856.68
Subtract 6160 from 6800 to get 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

Let's proceed to step 11:
If we divide 6400 by 770, we get 8 and a remainder of 240.
The number 8 becomes the next digit in our result. 
Result so far: 54856.688
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.

In conclusion, the division gives 54856.688 with a balance of 0.024.
