315570 divided by 77 
We're looking to find how many times 77 goes into 315570.

Step 1:
The number 77 fits into 3 0 times, leaving a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Fetch the next digit (1) from the dividend, attach it to 3 and continue: 31 / 77

Advancing to step 2:
31 divided by 77 is 0 with a remainder of 31.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 31, we get 31.
Append the next digit (5) from the dividend to 31 and continue with: 315 / 77

On to step 3:
77 goes into 315 4 times with a remainder of 7.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Subtracting 308 from 315 leaves us with 7.
Append the next digit (5) from the dividend to 7 and continue with: 75 / 77

Step 4:
If we divide 75 by 77, we get 0 and a remainder of 75.
Use 0 as the next digit of our solution. 
Result so far: 40.0
If we subtract 0 from 75, we get 75.
Bring next digit (7) of the dividend behind the 75 and repeat the process: 757 / 77

Let's proceed to step 5:
If we divide 757 by 77, we get 9 and a remainder of 64.
Put 9 as the next digit of the answer. 
Result so far: 409.0
The remainder is 64 after subtracting 693 from 757.
Include the next digit (0) from the dividend after 64, then repeat: 640 / 77

On to step 6:
If we divide 640 by 77, we get 8 and a remainder of 24.
The number 8 becomes the next digit in our result. 
Result so far: 4098.0
Subtract 616 from 640 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 7:
The number 77 fits into 240 3 times, leaving a remainder of 9.
Write down 3 as next digit of the result. 
Result so far: 4098.3
The remainder is 9 after subtracting 231 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Advancing to step 8:
77 goes into 90 1 times with a remainder of 13.
Put 1 as the next digit of the answer. 
Result so far: 4098.31
The remainder is 13 after subtracting 77 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Let's proceed to step 9:
The number 77 fits into 130 1 times, leaving a remainder of 53.
Use 1 as the next digit of our solution. 
Result so far: 4098.311
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.

In conclusion, the division gives 4098.311 with a balance of 0.0053.
