150866 divided by 77 
We want to figure out the number of times 150866 can be divided by 77.

Step 1:
1 divided by 77 is 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Grab the next digit (5) from the dividend, add it to 1, then carry on: 15 / 77

Step 2:
When dividing 15 by 77, we get 0 with a remainder of 15.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 15 leaves us with 15.
Include the next digit (0) from the dividend after 15, then repeat: 150 / 77

Moving on to step 3:
77 goes into 150 1 times with a remainder of 73.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 77 away from 150, we end up with 73.
Grab the next digit (8) from the dividend, add it to 73, then carry on: 738 / 77

On to step 4:
738 divided by 77 is 9 with a remainder of 45.
Write down 9 as next digit of the result. 
Result so far: 19.0
Subtract 693 from 738 to get 45.
Take the next digit (6) from the dividend and append it to 45, then repeat: 456 / 77

On to step 5:
When dividing 456 by 77, we get 5 with a remainder of 71.
Write down 5 as next digit of the result. 
Result so far: 195.0
Deduct 385 from 456 and we're left with 71.
Include the next digit (6) from the dividend after 71, then repeat: 716 / 77

Step 6:
The number 77 fits into 716 9 times, leaving a remainder of 23.
Put 9 as the next digit of the answer. 
Result so far: 1959.0
The remainder is 23 after subtracting 693 from 716.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Step 7:
If we divide 230 by 77, we get 2 and a remainder of 76.
The number 2 becomes the next digit in our result. 
Result so far: 1959.2
Subtracting 154 from 230 leaves us with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Advancing to step 8:
When dividing 760 by 77, we get 9 with a remainder of 67.
Put 9 as the next digit of the answer. 
Result so far: 1959.29
If we subtract 693 from 760, we get 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Let's proceed to step 9:
77 goes into 670 8 times with a remainder of 54.
Use 8 as the next digit of our solution. 
Result so far: 1959.298
Subtracting 616 from 670 leaves us with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Advancing to step 10:
If we divide 540 by 77, we get 7 and a remainder of 1.
Put 7 as the next digit of the answer. 
Result so far: 1959.2987
Subtracting 539 from 540 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 11:
77 can be fit into 10 0 times, resulting in a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 1959.2987
Subtracting 0 from 10 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 12:
77 goes into 100 1 times with a remainder of 23.
Record the quotient 1 as the next digit in the result. 
Result so far: 1959.298701
Subtracting 77 from 100 leaves us with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Moving on to step 13:
77 goes into 230 2 times with a remainder of 76.
Record the quotient 2 as the next digit in the result. 
Result so far: 1959.2987012
Deduct 154 from 230 and we're left with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Let's proceed to step 14:
77 can be fit into 760 9 times, resulting in a remainder of 67.
The next digit of our result is 9. 
Result so far: 1959.29870129
Subtract 693 from 760 to get 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

In conclusion, the division gives 1959.29870129 with a balance of 6.7e-08.
