We divide 308090 by 77
We want to figure out the number of times 308090 can be divided by 77.

Advancing to step 1:
77 can be fit into 3 0 times, resulting in a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Grab the next digit (0) from the dividend, add it to 3, then carry on: 30 / 77

Moving on to step 2:
77 goes into 30 0 times with a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 30, we get 30.
Bring next digit (8) of the dividend behind the 30 and repeat the process: 308 / 77

Moving on to step 3:
77 goes into 308 4 times with a remainder of 0.
Write down 4 as next digit of the result. 
Result so far: 4.0
Subtract 308 from 308 to get 0.
Grab the next digit (0) from the dividend, add it to 0, then carry on: 0 / 77

Going ahead to step 4:
77 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 40.0
If we take 0 away from 0, we end up with 0.
Grab the next digit (9) from the dividend, add it to 0, then carry on: 9 / 77

Let's proceed to step 5:
When dividing 9 by 77, we get 0 with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 400.0
The remainder is 9 after subtracting 0 from 9.
Append the next digit (0) from the dividend to 9 and continue with: 90 / 77

Step 6:
The number 77 fits into 90 1 times, leaving a remainder of 13.
Record the quotient 1 as the next digit in the result. 
Result so far: 4001.0
If we subtract 77 from 90, we get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Moving on to step 7:
When dividing 130 by 77, we get 1 with a remainder of 53.
The number 1 becomes the next digit in our result. 
Result so far: 4001.1
Subtracting 77 from 130 leaves us with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Moving on to step 8:
When dividing 530 by 77, we get 6 with a remainder of 68.
Record the quotient 6 as the next digit in the result. 
Result so far: 4001.16
Subtract 462 from 530 to get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Let's proceed to step 9:
680 divided by 77 is 8 with a remainder of 64.
The number 8 becomes the next digit in our result. 
Result so far: 4001.168
If we subtract 616 from 680, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Let's proceed to step 10:
The number 77 fits into 640 8 times, leaving a remainder of 24.
Write down 8 as next digit of the result. 
Result so far: 4001.1688
Subtracting 616 from 640 leaves us 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.

Our division results in 4001.1688 with a remaining 0.00024.
