We divide 51215329 by 320
We're looking to find how many times 320 goes into 51215329.

Moving on to step 1:
The number 320 fits into 5 0 times, leaving a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Append the next digit (1) from the dividend to 5 and continue with: 51 / 320

Let's proceed to step 2:
If we divide 51 by 320, we get 0 and a remainder of 51.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 51 leaves us with 51.
Include the next digit (2) from the dividend after 51, then repeat: 512 / 320

Let's proceed to step 3:
When dividing 512 by 320, we get 1 with a remainder of 192.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 192 after subtracting 320 from 512.
Take the next digit (1) from the dividend and append it to 192, then repeat: 1921 / 320

Step 4:
When dividing 1921 by 320, we get 6 with a remainder of 1.
Record the quotient 6 as the next digit in the result. 
Result so far: 16.0
Deduct 1920 from 1921 and we're left with 1.
Take the next digit (5) from the dividend and append it to 1, then repeat: 15 / 320

Advancing to step 5:
320 can be fit into 15 0 times, resulting in a remainder of 15.
Write down 0 as next digit of the result. 
Result so far: 160.0
If we take 0 away from 15, we end up with 15.
Append the next digit (3) from the dividend to 15 and continue with: 153 / 320

On to step 6:
153 divided by 320 is 0 with a remainder of 153.
Put 0 as the next digit of the answer. 
Result so far: 1600.0
Subtracting 0 from 153 leaves us with 153.
Append the next digit (2) from the dividend to 153 and continue with: 1532 / 320

Let's proceed to step 7:
1532 divided by 320 is 4 with a remainder of 252.
Use 4 as the next digit of our solution. 
Result so far: 16004.0
Subtract 1280 from 1532 to get 252.
Grab the next digit (9) from the dividend, add it to 252, then carry on: 2529 / 320

Let's proceed to step 8:
The number 320 fits into 2529 7 times, leaving a remainder of 289.
Write down 7 as next digit of the result. 
Result so far: 160047.0
Subtract 2240 from 2529 to get 289.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2890, and continue the process.

Let's proceed to step 9:
When dividing 2890 by 320, we get 9 with a remainder of 10.
The next digit of our result is 9. 
Result so far: 160047.9
Subtract 2880 from 2890 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 10:
100 divided by 320 is 0 with a remainder of 100.
Write down 0 as next digit of the result. 
Result so far: 160047.9
Subtract 0 from 100 to get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

On to step 11:
320 can be fit into 1000 3 times, resulting in a remainder of 40.
Put 3 as the next digit of the answer. 
Result so far: 160047.903
If we take 960 away from 1000, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 12:
The number 320 fits into 400 1 times, leaving a remainder of 80.
Put 1 as the next digit of the answer. 
Result so far: 160047.9031
Subtract 320 from 400 to get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Let's proceed to step 13:
The number 320 fits into 800 2 times, leaving a remainder of 160.
The number 2 becomes the next digit in our result. 
Result so far: 160047.90312
If we take 640 away from 800, we end up with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Moving on to step 14:
1600 divided by 320 is 5 with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 160047.903125
The remainder is 0 after subtracting 1600 from 1600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 15:
When dividing 0 by 320, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 160047.903125
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.

Let's proceed to step 16:
320 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 160047.903125
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 quotient of the division is 160047.903125, and the remainder is 0.0.
