66770077 divided by 668 
Let's see how many times 668 fits into 66770077.

On to step 1:
If we divide 6 by 668, we get 0 and a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Fetch the next digit (6) from the dividend, attach it to 6 and continue: 66 / 668

Advancing to step 2:
When dividing 66 by 668, we get 0 with a remainder of 66.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 66, we get 66.
Grab the next digit (7) from the dividend, add it to 66, then carry on: 667 / 668

On to step 3:
668 goes into 667 0 times with a remainder of 667.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 667, we get 667.
Take the next digit (7) from the dividend and append it to 667, then repeat: 6677 / 668

Moving on to step 4:
If we divide 6677 by 668, we get 9 and a remainder of 665.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
Subtracting 6012 from 6677 leaves us with 665.
Grab the next digit (0) from the dividend, add it to 665, then carry on: 6650 / 668

Moving on to step 5:
When dividing 6650 by 668, we get 9 with a remainder of 638.
Use 9 as the next digit of our solution. 
Result so far: 99.0
If we subtract 6012 from 6650, we get 638.
Include the next digit (0) from the dividend after 638, then repeat: 6380 / 668

Moving on to step 6:
If we divide 6380 by 668, we get 9 and a remainder of 368.
Use 9 as the next digit of our solution. 
Result so far: 999.0
Subtracting 6012 from 6380 leaves us with 368.
Fetch the next digit (7) from the dividend, attach it to 368 and continue: 3687 / 668

Step 7:
668 can be fit into 3687 5 times, resulting in a remainder of 347.
Write down 5 as next digit of the result. 
Result so far: 9995.0
If we subtract 3340 from 3687, we get 347.
Include the next digit (7) from the dividend after 347, then repeat: 3477 / 668

Advancing to step 8:
If we divide 3477 by 668, we get 5 and a remainder of 137.
Record the quotient 5 as the next digit in the result. 
Result so far: 99955.0
The remainder is 137 after subtracting 3340 from 3477.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1370, and continue the process.

Let's proceed to step 9:
If we divide 1370 by 668, we get 2 and a remainder of 34.
Record the quotient 2 as the next digit in the result. 
Result so far: 99955.2
Deduct 1336 from 1370 and we're left with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Moving on to step 10:
The number 668 fits into 340 0 times, leaving a remainder of 340.
The number 0 becomes the next digit in our result. 
Result so far: 99955.2
Subtract 0 from 340 to get 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Let's proceed to step 11:
668 goes into 3400 5 times with a remainder of 60.
The number 5 becomes the next digit in our result. 
Result so far: 99955.205
If we take 3340 away from 3400, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 12:
668 can be fit into 600 0 times, resulting in a remainder of 600.
The next digit of our result is 0. 
Result so far: 99955.205
Subtracting 0 from 600 leaves us with 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

Going ahead to step 13:
The number 668 fits into 6000 8 times, leaving a remainder of 656.
Record the quotient 8 as the next digit in the result. 
Result so far: 99955.20508
If we subtract 5344 from 6000, we get 656.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6560, and continue the process.

Going ahead to step 14:
668 can be fit into 6560 9 times, resulting in a remainder of 548.
Use 9 as the next digit of our solution. 
Result so far: 99955.205089
Deduct 6012 from 6560 and we're left with 548.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5480, and continue the process.

On to step 15:
The number 668 fits into 5480 8 times, leaving a remainder of 136.
The number 8 becomes the next digit in our result. 
Result so far: 99955.2050898
If we subtract 5344 from 5480, we get 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Let's proceed to step 16:
1360 divided by 668 is 2 with a remainder of 24.
Put 2 as the next digit of the answer. 
Result so far: 99955.20508982
If we take 1336 away from 1360, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

In conclusion, the division gives 99955.20508982 with a balance of 2.4e-08.
