We want to divide 66265663 by 770.

Moving on to step 1:
6 divided by 770 is 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Take the next digit (6) from the dividend and append it to 6, then repeat: 66 / 770

Going ahead to step 2:
770 can be fit into 66 0 times, resulting in a remainder of 66.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 66 leaves us with 66.
Append the next digit (2) from the dividend to 66 and continue with: 662 / 770

Moving on to step 3:
If we divide 662 by 770, we get 0 and a remainder of 662.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 662 leaves us with 662.
Include the next digit (6) from the dividend after 662, then repeat: 6626 / 770

Advancing to step 4:
If we divide 6626 by 770, we get 8 and a remainder of 466.
Write down 8 as next digit of the result. 
Result so far: 8.0
The remainder is 466 after subtracting 6160 from 6626.
Include the next digit (5) from the dividend after 466, then repeat: 4665 / 770

Moving on to step 5:
If we divide 4665 by 770, we get 6 and a remainder of 45.
The number 6 becomes the next digit in our result. 
Result so far: 86.0
Subtracting 4620 from 4665 leaves us with 45.
Append the next digit (6) from the dividend to 45 and continue with: 456 / 770

Step 6:
When dividing 456 by 770, we get 0 with a remainder of 456.
The next digit of our result is 0. 
Result so far: 860.0
If we take 0 away from 456, we end up with 456.
Fetch the next digit (6) from the dividend, attach it to 456 and continue: 4566 / 770

Let's proceed to step 7:
The number 770 fits into 4566 5 times, leaving a remainder of 716.
The number 5 becomes the next digit in our result. 
Result so far: 8605.0
Subtract 3850 from 4566 to get 716.
Grab the next digit (3) from the dividend, add it to 716, then carry on: 7163 / 770

Advancing to step 8:
770 can be fit into 7163 9 times, resulting in a remainder of 233.
The next digit of our result is 9. 
Result so far: 86059.0
Subtract 6930 from 7163 to get 233.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2330, and continue the process.

Step 9:
When dividing 2330 by 770, we get 3 with a remainder of 20.
Use 3 as the next digit of our solution. 
Result so far: 86059.3
Subtracting 2310 from 2330 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 10:
200 divided by 770 is 0 with a remainder of 200.
Record the quotient 0 as the next digit in the result. 
Result so far: 86059.3
Deduct 0 from 200 and we're left with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Let's proceed to step 11:
2000 divided by 770 is 2 with a remainder of 460.
Use 2 as the next digit of our solution. 
Result so far: 86059.302
If we subtract 1540 from 2000, we get 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

Moving on to step 12:
The number 770 fits into 4600 5 times, leaving a remainder of 750.
The next digit of our result is 5. 
Result so far: 86059.3025
The remainder is 750 after subtracting 3850 from 4600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7500, and continue the process.

On to step 13:
770 can be fit into 7500 9 times, resulting in a remainder of 570.
Put 9 as the next digit of the answer. 
Result so far: 86059.30259
The remainder is 570 after subtracting 6930 from 7500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5700, and continue the process.

Let's proceed to step 14:
770 goes into 5700 7 times with a remainder of 310.
Write down 7 as next digit of the result. 
Result so far: 86059.302597
If we subtract 5390 from 5700, we get 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

Step 15:
When dividing 3100 by 770, we get 4 with a remainder of 20.
Use 4 as the next digit of our solution. 
Result so far: 86059.3025974
If we subtract 3080 from 3100, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 16:
If we divide 200 by 770, we get 0 and a remainder of 200.
The number 0 becomes the next digit in our result. 
Result so far: 86059.3025974
If we subtract 0 from 200, we get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

In conclusion, the division gives 86059.3025974 with a balance of 2e-07.
