69660960 ÷ 777 
Let's see how many times 777 fits into 69660960.

Let's proceed to step 1:
When dividing 6 by 777, we get 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Grab the next digit (9) from the dividend, add it to 6, then carry on: 69 / 777

Moving on to step 2:
The number 777 fits into 69 0 times, leaving a remainder of 69.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 69, we get 69.
Fetch the next digit (6) from the dividend, attach it to 69 and continue: 696 / 777

Advancing to step 3:
696 divided by 777 is 0 with a remainder of 696.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 696 and we're left with 696.
Include the next digit (6) from the dividend after 696, then repeat: 6966 / 777

Step 4:
When dividing 6966 by 777, we get 8 with a remainder of 750.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Deduct 6216 from 6966 and we're left with 750.
Fetch the next digit (0) from the dividend, attach it to 750 and continue: 7500 / 777

Moving on to step 5:
The number 777 fits into 7500 9 times, leaving a remainder of 507.
The next digit of our result is 9. 
Result so far: 89.0
If we take 6993 away from 7500, we end up with 507.
Take the next digit (9) from the dividend and append it to 507, then repeat: 5079 / 777

Let's proceed to step 6:
5079 divided by 777 is 6 with a remainder of 417.
Put 6 as the next digit of the answer. 
Result so far: 896.0
The remainder is 417 after subtracting 4662 from 5079.
Append the next digit (6) from the dividend to 417 and continue with: 4176 / 777

Going ahead to step 7:
777 goes into 4176 5 times with a remainder of 291.
Write down 5 as next digit of the result. 
Result so far: 8965.0
The remainder is 291 after subtracting 3885 from 4176.
Fetch the next digit (0) from the dividend, attach it to 291 and continue: 2910 / 777

On to step 8:
If we divide 2910 by 777, we get 3 and a remainder of 579.
Record the quotient 3 as the next digit in the result. 
Result so far: 89653.0
If we subtract 2331 from 2910, we get 579.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5790, and continue the process.

On to step 9:
5790 divided by 777 is 7 with a remainder of 351.
Write down 7 as next digit of the result. 
Result so far: 89653.7
Subtracting 5439 from 5790 leaves us with 351.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3510, and continue the process.

Step 10:
If we divide 3510 by 777, we get 4 and a remainder of 402.
Use 4 as the next digit of our solution. 
Result so far: 89653.74
Deduct 3108 from 3510 and we're left with 402.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4020, and continue the process.

On to step 11:
777 can be fit into 4020 5 times, resulting in a remainder of 135.
Put 5 as the next digit of the answer. 
Result so far: 89653.745
If we subtract 3885 from 4020, we get 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

Let's proceed to step 12:
If we divide 1350 by 777, we get 1 and a remainder of 573.
Record the quotient 1 as the next digit in the result. 
Result so far: 89653.7451
Subtracting 777 from 1350 leaves us with 573.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5730, and continue the process.

Step 13:
5730 divided by 777 is 7 with a remainder of 291.
Record the quotient 7 as the next digit in the result. 
Result so far: 89653.74517
If we subtract 5439 from 5730, we get 291.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2910, and continue the process.

On to step 14:
777 goes into 2910 3 times with a remainder of 579.
The number 3 becomes the next digit in our result. 
Result so far: 89653.745173
Subtract 2331 from 2910 to get 579.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5790, and continue the process.

Let's proceed to step 15:
777 goes into 5790 7 times with a remainder of 351.
The next digit of our result is 7. 
Result so far: 89653.7451737
The remainder is 351 after subtracting 5439 from 5790.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3510, and continue the process.

Going ahead to step 16:
If we divide 3510 by 777, we get 4 and a remainder of 402.
Use 4 as the next digit of our solution. 
Result so far: 89653.74517374
If we take 3108 away from 3510, we end up with 402.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4020, and continue the process.

After the division, we end up with 89653.74517374 and a remainder of 4.02e-07.
