Let's divide 76888 by 77
We want to figure out the number of times 76888 can be divided by 77.

Step 1:
When dividing 7 by 77, we get 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Include the next digit (6) from the dividend after 7, then repeat: 76 / 77

On to step 2:
When dividing 76 by 77, we get 0 with a remainder of 76.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 76, we get 76.
Include the next digit (8) from the dividend after 76, then repeat: 768 / 77

Step 3:
The number 77 fits into 768 9 times, leaving a remainder of 75.
The next digit of our result is 9. 
Result so far: 9.0
Subtracting 693 from 768 leaves us with 75.
Include the next digit (8) from the dividend after 75, then repeat: 758 / 77

Moving on to step 4:
758 divided by 77 is 9 with a remainder of 65.
Write down 9 as next digit of the result. 
Result so far: 99.0
If we subtract 693 from 758, we get 65.
Bring next digit (8) of the dividend behind the 65 and repeat the process: 658 / 77

Step 5:
When dividing 658 by 77, we get 8 with a remainder of 42.
The number 8 becomes the next digit in our result. 
Result so far: 998.0
Subtracting 616 from 658 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Advancing to step 6:
If we divide 420 by 77, we get 5 and a remainder of 35.
Record the quotient 5 as the next digit in the result. 
Result so far: 998.5
Subtract 385 from 420 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Advancing to step 7:
If we divide 350 by 77, we get 4 and a remainder of 42.
Put 4 as the next digit of the answer. 
Result so far: 998.54
If we take 308 away from 350, we end up with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

On to step 8:
When dividing 420 by 77, we get 5 with a remainder of 35.
Record the quotient 5 as the next digit in the result. 
Result so far: 998.545
Subtract 385 from 420 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Advancing to step 9:
When dividing 350 by 77, we get 4 with a remainder of 42.
The number 4 becomes the next digit in our result. 
Result so far: 998.5454
Subtract 308 from 350 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Step 10:
The number 77 fits into 420 5 times, leaving a remainder of 35.
The next digit of our result is 5. 
Result so far: 998.54545
Subtract 385 from 420 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Step 11:
If we divide 350 by 77, we get 4 and a remainder of 42.
Record the quotient 4 as the next digit in the result. 
Result so far: 998.545454
The remainder is 42 after subtracting 308 from 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Let's proceed to step 12:
The number 77 fits into 420 5 times, leaving a remainder of 35.
Use 5 as the next digit of our solution. 
Result so far: 998.5454545
Subtract 385 from 420 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Step 13:
77 can be fit into 350 4 times, resulting in a remainder of 42.
Write down 4 as next digit of the result. 
Result so far: 998.54545454
Deduct 308 from 350 and we're left with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Our division results in 998.54545454 with a remaining 4.2e-08.
