Let's divide 66123772 by 772
We want to figure out the number of times 66123772 can be divided by 772.

Let's proceed to step 1:
772 can be fit into 6 0 times, resulting in a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Include the next digit (6) from the dividend after 6, then repeat: 66 / 772

Going ahead to step 2:
If we divide 66 by 772, we get 0 and a remainder of 66.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 66, we get 66.
Bring next digit (1) of the dividend behind the 66 and repeat the process: 661 / 772

Going ahead to step 3:
772 can be fit into 661 0 times, resulting in a remainder of 661.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 661 after subtracting 0 from 661.
Take the next digit (2) from the dividend and append it to 661, then repeat: 6612 / 772

Moving on to step 4:
6612 divided by 772 is 8 with a remainder of 436.
Write down 8 as next digit of the result. 
Result so far: 8.0
If we take 6176 away from 6612, we end up with 436.
Fetch the next digit (3) from the dividend, attach it to 436 and continue: 4363 / 772

On to step 5:
772 can be fit into 4363 5 times, resulting in a remainder of 503.
The number 5 becomes the next digit in our result. 
Result so far: 85.0
If we subtract 3860 from 4363, we get 503.
Grab the next digit (7) from the dividend, add it to 503, then carry on: 5037 / 772

Let's proceed to step 6:
When dividing 5037 by 772, we get 6 with a remainder of 405.
Record the quotient 6 as the next digit in the result. 
Result so far: 856.0
The remainder is 405 after subtracting 4632 from 5037.
Grab the next digit (7) from the dividend, add it to 405, then carry on: 4057 / 772

Moving on to step 7:
772 goes into 4057 5 times with a remainder of 197.
The number 5 becomes the next digit in our result. 
Result so far: 8565.0
Subtract 3860 from 4057 to get 197.
Fetch the next digit (2) from the dividend, attach it to 197 and continue: 1972 / 772

On to step 8:
The number 772 fits into 1972 2 times, leaving a remainder of 428.
The next digit of our result is 2. 
Result so far: 85652.0
Subtracting 1544 from 1972 leaves us with 428.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4280, and continue the process.

Advancing to step 9:
If we divide 4280 by 772, we get 5 and a remainder of 420.
The number 5 becomes the next digit in our result. 
Result so far: 85652.5
Deduct 3860 from 4280 and we're left with 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

On to step 10:
772 can be fit into 4200 5 times, resulting in a remainder of 340.
Use 5 as the next digit of our solution. 
Result so far: 85652.55
Subtracting 3860 from 4200 leaves us with 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

The quotient of the division is 85652.55, and the remainder is 0.34.
