We're dividing 309247 by 77 
We're looking to find how many times 77 goes into 309247.

Going ahead to step 1:
When dividing 3 by 77, we get 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Grab the next digit (0) from the dividend, add it to 3, then carry on: 30 / 77

Step 2:
If we divide 30 by 77, we get 0 and a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 30 and we're left with 30.
Grab the next digit (9) from the dividend, add it to 30, then carry on: 309 / 77

Going ahead to step 3:
77 goes into 309 4 times with a remainder of 1.
The next digit of our result is 4. 
Result so far: 4.0
If we subtract 308 from 309, we get 1.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 77

Going ahead to step 4:
12 divided by 77 is 0 with a remainder of 12.
Record the quotient 0 as the next digit in the result. 
Result so far: 40.0
If we take 0 away from 12, we end up with 12.
Grab the next digit (4) from the dividend, add it to 12, then carry on: 124 / 77

Let's proceed to step 5:
77 goes into 124 1 times with a remainder of 47.
The next digit of our result is 1. 
Result so far: 401.0
Deduct 77 from 124 and we're left with 47.
Append the next digit (7) from the dividend to 47 and continue with: 477 / 77

On to step 6:
When dividing 477 by 77, we get 6 with a remainder of 15.
Record the quotient 6 as the next digit in the result. 
Result so far: 4016.0
Subtract 462 from 477 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 7:
77 goes into 150 1 times with a remainder of 73.
Write down 1 as next digit of the result. 
Result so far: 4016.1
Subtracting 77 from 150 leaves us with 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Advancing to step 8:
The number 77 fits into 730 9 times, leaving a remainder of 37.
The number 9 becomes the next digit in our result. 
Result so far: 4016.19
Subtract 693 from 730 to get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Going ahead to step 9:
The number 77 fits into 370 4 times, leaving a remainder of 62.
Use 4 as the next digit of our solution. 
Result so far: 4016.194
Subtracting 308 from 370 leaves us with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Step 10:
If we divide 620 by 77, we get 8 and a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 4016.1948
Deduct 616 from 620 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 11:
The number 77 fits into 40 0 times, leaving a remainder of 40.
The next digit of our result is 0. 
Result so far: 4016.1948
If we take 0 away from 40, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 12:
When dividing 400 by 77, we get 5 with a remainder of 15.
The next digit of our result is 5. 
Result so far: 4016.194805
If we subtract 385 from 400, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 13:
The number 77 fits into 150 1 times, leaving a remainder of 73.
Use 1 as the next digit of our solution. 
Result so far: 4016.1948051
Subtracting 77 from 150 leaves us with 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Moving on to step 14:
The number 77 fits into 730 9 times, leaving a remainder of 37.
Put 9 as the next digit of the answer. 
Result so far: 4016.19480519
Subtract 693 from 730 to get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

The final result is 4016.19480519 with a remainder of 3.7e-08.
