69720120 divided by 320 
We want to divide 69720120 by 320.

Let's proceed to step 1:
320 goes into 6 0 times with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Append the next digit (9) from the dividend to 6 and continue with: 69 / 320

Advancing to step 2:
69 divided by 320 is 0 with a remainder of 69.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 69 leaves us with 69.
Bring next digit (7) of the dividend behind the 69 and repeat the process: 697 / 320

Going ahead to step 3:
320 goes into 697 2 times with a remainder of 57.
The next digit of our result is 2. 
Result so far: 2.0
Subtract 640 from 697 to get 57.
Append the next digit (2) from the dividend to 57 and continue with: 572 / 320

Step 4:
When dividing 572 by 320, we get 1 with a remainder of 252.
The number 1 becomes the next digit in our result. 
Result so far: 21.0
Deduct 320 from 572 and we're left with 252.
Include the next digit (0) from the dividend after 252, then repeat: 2520 / 320

Step 5:
If we divide 2520 by 320, we get 7 and a remainder of 280.
Record the quotient 7 as the next digit in the result. 
Result so far: 217.0
If we take 2240 away from 2520, we end up with 280.
Include the next digit (1) from the dividend after 280, then repeat: 2801 / 320

Step 6:
If we divide 2801 by 320, we get 8 and a remainder of 241.
Record the quotient 8 as the next digit in the result. 
Result so far: 2178.0
If we take 2560 away from 2801, we end up with 241.
Bring next digit (2) of the dividend behind the 241 and repeat the process: 2412 / 320

Let's proceed to step 7:
320 can be fit into 2412 7 times, resulting in a remainder of 172.
The next digit of our result is 7. 
Result so far: 21787.0
Deduct 2240 from 2412 and we're left with 172.
Take the next digit (0) from the dividend and append it to 172, then repeat: 1720 / 320

Moving on to step 8:
If we divide 1720 by 320, we get 5 and a remainder of 120.
The next digit of our result is 5. 
Result so far: 217875.0
The remainder is 120 after subtracting 1600 from 1720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Moving on to step 9:
If we divide 1200 by 320, we get 3 and a remainder of 240.
The next digit of our result is 3. 
Result so far: 217875.3
If we take 960 away from 1200, we end up with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Moving on to step 10:
The number 320 fits into 2400 7 times, leaving a remainder of 160.
Put 7 as the next digit of the answer. 
Result so far: 217875.37
If we subtract 2240 from 2400, 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.

Step 11:
1600 divided by 320 is 5 with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 217875.375
Subtract 1600 from 1600 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.

Moving on to step 12:
0 divided by 320 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 217875.375
If we subtract 0 from 0, we 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.

Moving on to step 13:
0 divided by 320 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 217875.375
The remainder is 0 after subtracting 0 from 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 outcome is 217875.375, with a leftover of 0.0.
