We're dividing 315119 by 77 
We want to divide 315119 by 77.

Let's proceed 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
Subtract 0 from 3 to get 3.
Append the next digit (1) from the dividend to 3 and continue with: 31 / 77

On to step 2:
The number 77 fits into 31 0 times, leaving a remainder of 31.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 31, we end up with 31.
Bring next digit (5) of the dividend behind the 31 and repeat the process: 315 / 77

Advancing to step 3:
77 can be fit into 315 4 times, resulting in a remainder of 7.
The next digit of our result is 4. 
Result so far: 4.0
If we take 308 away from 315, we end up with 7.
Append the next digit (1) from the dividend to 7 and continue with: 71 / 77

Moving on to step 4:
77 goes into 71 0 times with a remainder of 71.
Put 0 as the next digit of the answer. 
Result so far: 40.0
Subtract 0 from 71 to get 71.
Bring next digit (1) of the dividend behind the 71 and repeat the process: 711 / 77

Step 5:
If we divide 711 by 77, we get 9 and a remainder of 18.
Record the quotient 9 as the next digit in the result. 
Result so far: 409.0
Subtracting 693 from 711 leaves us with 18.
Include the next digit (9) from the dividend after 18, then repeat: 189 / 77

Advancing to step 6:
189 divided by 77 is 2 with a remainder of 35.
Use 2 as the next digit of our solution. 
Result so far: 4092.0
The remainder is 35 after subtracting 154 from 189.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Moving on to step 7:
350 divided by 77 is 4 with a remainder of 42.
Use 4 as the next digit of our solution. 
Result so far: 4092.4
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.

Let's proceed to step 8:
The number 77 fits into 420 5 times, leaving a remainder of 35.
The number 5 becomes the next digit in our result. 
Result so far: 4092.45
If we subtract 385 from 420, we 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.

Moving on to step 9:
If we divide 350 by 77, we get 4 and a remainder of 42.
The next digit of our result is 4. 
Result so far: 4092.454
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 10:
77 can be fit into 420 5 times, resulting in a remainder of 35.
Put 5 as the next digit of the answer. 
Result so far: 4092.4545
Subtracting 385 from 420 leaves us with 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:
350 divided by 77 is 4 with a remainder of 42.
The number 4 becomes the next digit in our result. 
Result so far: 4092.45454
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.

Advancing to step 12:
420 divided by 77 is 5 with a remainder of 35.
Put 5 as the next digit of the answer. 
Result so far: 4092.454545
Subtracting 385 from 420 leaves us with 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 13:
When dividing 350 by 77, we get 4 with a remainder of 42.
The next digit of our result is 4. 
Result so far: 4092.4545454
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.

Step 14:
77 can be fit into 420 5 times, resulting in a remainder of 35.
The next digit of our result is 5. 
Result so far: 4092.45454545
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.

After the division, we end up with 4092.45454545 and a remainder of 3.5e-08.
