We're dividing 56511380 by 320 
Let's see how many times 320 fits into 56511380.

Going ahead to step 1:
320 goes into 5 0 times with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Bring next digit (6) of the dividend behind the 5 and repeat the process: 56 / 320

On to step 2:
When dividing 56 by 320, we get 0 with a remainder of 56.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 56, we get 56.
Append the next digit (5) from the dividend to 56 and continue with: 565 / 320

On to step 3:
320 goes into 565 1 times with a remainder of 245.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 320 from 565, we get 245.
Append the next digit (1) from the dividend to 245 and continue with: 2451 / 320

Step 4:
The number 320 fits into 2451 7 times, leaving a remainder of 211.
Write down 7 as next digit of the result. 
Result so far: 17.0
Deduct 2240 from 2451 and we're left with 211.
Grab the next digit (1) from the dividend, add it to 211, then carry on: 2111 / 320

Moving on to step 5:
If we divide 2111 by 320, we get 6 and a remainder of 191.
The number 6 becomes the next digit in our result. 
Result so far: 176.0
If we take 1920 away from 2111, we end up with 191.
Fetch the next digit (3) from the dividend, attach it to 191 and continue: 1913 / 320

Advancing to step 6:
320 can be fit into 1913 5 times, resulting in a remainder of 313.
Write down 5 as next digit of the result. 
Result so far: 1765.0
If we take 1600 away from 1913, we end up with 313.
Take the next digit (8) from the dividend and append it to 313, then repeat: 3138 / 320

On to step 7:
3138 divided by 320 is 9 with a remainder of 258.
Use 9 as the next digit of our solution. 
Result so far: 17659.0
If we subtract 2880 from 3138, we get 258.
Include the next digit (0) from the dividend after 258, then repeat: 2580 / 320

Advancing to step 8:
When dividing 2580 by 320, we get 8 with a remainder of 20.
Write down 8 as next digit of the result. 
Result so far: 176598.0
Deduct 2560 from 2580 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 9:
320 goes into 200 0 times with a remainder of 200.
Write down 0 as next digit of the result. 
Result so far: 176598.0
Deduct 0 from 200 and we're left with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Step 10:
320 can be fit into 2000 6 times, resulting in a remainder of 80.
Use 6 as the next digit of our solution. 
Result so far: 176598.06
Deduct 1920 from 2000 and we're left with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

On to step 11:
320 can be fit into 800 2 times, resulting in a remainder of 160.
Put 2 as the next digit of the answer. 
Result so far: 176598.062
If we subtract 640 from 800, we get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Going ahead to step 12:
When dividing 1600 by 320, we get 5 with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 176598.0625
Subtracting 1600 from 1600 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 13:
0 divided by 320 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 176598.0625
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 14:
320 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 176598.0625
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 176598.0625 with a remainder of 0.0.
