We're dividing 77557949 by 560 
We're looking to find how many times 560 goes into 77557949.

Going ahead to step 1:
The number 560 fits into 7 0 times, leaving a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Take the next digit (7) from the dividend and append it to 7, then repeat: 77 / 560

Going ahead to step 2:
77 divided by 560 is 0 with a remainder of 77.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 77 and we're left with 77.
Append the next digit (5) from the dividend to 77 and continue with: 775 / 560

Advancing to step 3:
560 can be fit into 775 1 times, resulting in a remainder of 215.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 560 away from 775, we end up with 215.
Include the next digit (5) from the dividend after 215, then repeat: 2155 / 560

Let's proceed to step 4:
If we divide 2155 by 560, we get 3 and a remainder of 475.
Put 3 as the next digit of the answer. 
Result so far: 13.0
If we subtract 1680 from 2155, we get 475.
Bring next digit (7) of the dividend behind the 475 and repeat the process: 4757 / 560

Advancing to step 5:
If we divide 4757 by 560, we get 8 and a remainder of 277.
Put 8 as the next digit of the answer. 
Result so far: 138.0
Subtracting 4480 from 4757 leaves us with 277.
Append the next digit (9) from the dividend to 277 and continue with: 2779 / 560

Advancing to step 6:
560 can be fit into 2779 4 times, resulting in a remainder of 539.
The number 4 becomes the next digit in our result. 
Result so far: 1384.0
Subtracting 2240 from 2779 leaves us with 539.
Bring next digit (4) of the dividend behind the 539 and repeat the process: 5394 / 560

Step 7:
If we divide 5394 by 560, we get 9 and a remainder of 354.
Record the quotient 9 as the next digit in the result. 
Result so far: 13849.0
The remainder is 354 after subtracting 5040 from 5394.
Fetch the next digit (9) from the dividend, attach it to 354 and continue: 3549 / 560

Going ahead to step 8:
The number 560 fits into 3549 6 times, leaving a remainder of 189.
The number 6 becomes the next digit in our result. 
Result so far: 138496.0
The remainder is 189 after subtracting 3360 from 3549.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1890, and continue the process.

Advancing to step 9:
The number 560 fits into 1890 3 times, leaving a remainder of 210.
The next digit of our result is 3. 
Result so far: 138496.3
The remainder is 210 after subtracting 1680 from 1890.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Advancing to step 10:
2100 divided by 560 is 3 with a remainder of 420.
Write down 3 as next digit of the result. 
Result so far: 138496.33
The remainder is 420 after subtracting 1680 from 2100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

The final result is 138496.33 with a remainder of 0.42.
