We divide 309955 by 77
We're looking to find how many times 77 goes into 309955.

Step 1:
If we divide 3 by 77, we get 0 and a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Grab the next digit (0) from the dividend, add it to 3, then carry on: 30 / 77

Advancing to step 2:
If we divide 30 by 77, we get 0 and a remainder of 30.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 30, we end up with 30.
Take the next digit (9) from the dividend and append it to 30, then repeat: 309 / 77

Let's proceed to step 3:
If we divide 309 by 77, we get 4 and a remainder of 1.
Write down 4 as next digit of the result. 
Result so far: 4.0
Subtracting 308 from 309 leaves us with 1.
Bring next digit (9) of the dividend behind the 1 and repeat the process: 19 / 77

Moving on to step 4:
The number 77 fits into 19 0 times, leaving a remainder of 19.
The next digit of our result is 0. 
Result so far: 40.0
Deduct 0 from 19 and we're left with 19.
Take the next digit (5) from the dividend and append it to 19, then repeat: 195 / 77

Moving on to step 5:
When dividing 195 by 77, we get 2 with a remainder of 41.
The next digit of our result is 2. 
Result so far: 402.0
The remainder is 41 after subtracting 154 from 195.
Take the next digit (5) from the dividend and append it to 41, then repeat: 415 / 77

Moving on to step 6:
77 can be fit into 415 5 times, resulting in a remainder of 30.
The number 5 becomes the next digit in our result. 
Result so far: 4025.0
If we take 385 away from 415, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 7:
If we divide 300 by 77, we get 3 and a remainder of 69.
Record the quotient 3 as the next digit in the result. 
Result so far: 4025.3
If we take 231 away from 300, we end up with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Moving on to step 8:
77 goes into 690 8 times with a remainder of 74.
Put 8 as the next digit of the answer. 
Result so far: 4025.38
The remainder is 74 after subtracting 616 from 690.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Going ahead to step 9:
If we divide 740 by 77, we get 9 and a remainder of 47.
Write down 9 as next digit of the result. 
Result so far: 4025.389
The remainder is 47 after subtracting 693 from 740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Let's proceed to step 10:
If we divide 470 by 77, we get 6 and a remainder of 8.
Put 6 as the next digit of the answer. 
Result so far: 4025.3896
Subtract 462 from 470 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 11:
If we divide 80 by 77, we get 1 and a remainder of 3.
The next digit of our result is 1. 
Result so far: 4025.38961
The remainder is 3 after subtracting 77 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 12:
If we divide 30 by 77, we get 0 and a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 4025.38961
Subtracting 0 from 30 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 13:
If we divide 300 by 77, we get 3 and a remainder of 69.
Write down 3 as next digit of the result. 
Result so far: 4025.3896103
Subtract 231 from 300 to get 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Moving on to step 14:
The number 77 fits into 690 8 times, leaving a remainder of 74.
Write down 8 as next digit of the result. 
Result so far: 4025.38961038
Subtracting 616 from 690 leaves us with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

The quotient of the division is 4025.38961038, and the remainder is 7.4e-08.
