Let's divide 66018980 by 770
We want to figure out the number of times 66018980 can be divided by 770.

Going ahead to step 1:
770 goes into 6 0 times with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Bring next digit (6) of the dividend behind the 6 and repeat the process: 66 / 770

Let's proceed to step 2:
770 can be fit into 66 0 times, resulting in a remainder of 66.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 66, we end up with 66.
Include the next digit (0) from the dividend after 66, then repeat: 660 / 770

Let's proceed to step 3:
770 can be fit into 660 0 times, resulting in a remainder of 660.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 660 leaves us with 660.
Bring next digit (1) of the dividend behind the 660 and repeat the process: 6601 / 770

Moving on to step 4:
770 can be fit into 6601 8 times, resulting in a remainder of 441.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Deduct 6160 from 6601 and we're left with 441.
Append the next digit (8) from the dividend to 441 and continue with: 4418 / 770

Advancing to step 5:
4418 divided by 770 is 5 with a remainder of 568.
Write down 5 as next digit of the result. 
Result so far: 85.0
If we subtract 3850 from 4418, we get 568.
Fetch the next digit (9) from the dividend, attach it to 568 and continue: 5689 / 770

Let's proceed to step 6:
When dividing 5689 by 770, we get 7 with a remainder of 299.
The next digit of our result is 7. 
Result so far: 857.0
The remainder is 299 after subtracting 5390 from 5689.
Append the next digit (8) from the dividend to 299 and continue with: 2998 / 770

On to step 7:
If we divide 2998 by 770, we get 3 and a remainder of 688.
The number 3 becomes the next digit in our result. 
Result so far: 8573.0
Subtracting 2310 from 2998 leaves us with 688.
Append the next digit (0) from the dividend to 688 and continue with: 6880 / 770

On to step 8:
If we divide 6880 by 770, we get 8 and a remainder of 720.
The number 8 becomes the next digit in our result. 
Result so far: 85738.0
Subtracting 6160 from 6880 leaves us with 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7200, and continue the process.

Step 9:
When dividing 7200 by 770, we get 9 with a remainder of 270.
Write down 9 as next digit of the result. 
Result so far: 85738.9
Subtract 6930 from 7200 to get 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

Advancing to 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: 85738.93
Subtract 2310 from 2700 to get 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3900, and continue the process.

Advancing to step 11:
When dividing 3900 by 770, we get 5 with a remainder of 50.
The next digit of our result is 5. 
Result so far: 85738.935
Subtract 3850 from 3900 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 12:
770 goes into 500 0 times with a remainder of 500.
The next digit of our result is 0. 
Result so far: 85738.935
Deduct 0 from 500 and we're left 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.

Going ahead to step 13:
770 goes into 5000 6 times with a remainder of 380.
The next digit of our result is 6. 
Result so far: 85738.93506
Subtracting 4620 from 5000 leaves us 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:
3800 divided by 770 is 4 with a remainder of 720.
Record the quotient 4 as the next digit in the result. 
Result so far: 85738.935064
The remainder is 720 after subtracting 3080 from 3800.
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 can be fit into 7200 9 times, resulting in a remainder of 270.
Record the quotient 9 as the next digit in the result. 
Result so far: 85738.9350649
The remainder is 270 after subtracting 6930 from 7200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

On to step 16:
When dividing 2700 by 770, we get 3 with a remainder of 390.
Record the quotient 3 as the next digit in the result. 
Result so far: 85738.93506493
Subtract 2310 from 2700 to get 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3900, and continue the process.

The final result is 85738.93506493 with a remainder of 3.9e-07.
