We look at the division of 87199715 by 320 
We're looking to find how many times 320 goes into 87199715.

On to step 1:
320 goes into 8 0 times with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Grab the next digit (7) from the dividend, add it to 8, then carry on: 87 / 320

Moving on to step 2:
87 divided by 320 is 0 with a remainder of 87.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 87 to get 87.
Bring next digit (1) of the dividend behind the 87 and repeat the process: 871 / 320

Going ahead to step 3:
If we divide 871 by 320, we get 2 and a remainder of 231.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtracting 640 from 871 leaves us with 231.
Bring next digit (9) of the dividend behind the 231 and repeat the process: 2319 / 320

Step 4:
The number 320 fits into 2319 7 times, leaving a remainder of 79.
Record the quotient 7 as the next digit in the result. 
Result so far: 27.0
Subtract 2240 from 2319 to get 79.
Fetch the next digit (9) from the dividend, attach it to 79 and continue: 799 / 320

Let's proceed to step 5:
320 can be fit into 799 2 times, resulting in a remainder of 159.
Use 2 as the next digit of our solution. 
Result so far: 272.0
The remainder is 159 after subtracting 640 from 799.
Append the next digit (7) from the dividend to 159 and continue with: 1597 / 320

On to step 6:
320 goes into 1597 4 times with a remainder of 317.
Use 4 as the next digit of our solution. 
Result so far: 2724.0
If we take 1280 away from 1597, we end up with 317.
Take the next digit (1) from the dividend and append it to 317, then repeat: 3171 / 320

Step 7:
When dividing 3171 by 320, we get 9 with a remainder of 291.
Put 9 as the next digit of the answer. 
Result so far: 27249.0
Deduct 2880 from 3171 and we're left with 291.
Grab the next digit (5) from the dividend, add it to 291, then carry on: 2915 / 320

Step 8:
320 can be fit into 2915 9 times, resulting in a remainder of 35.
Record the quotient 9 as the next digit in the result. 
Result so far: 272499.0
Subtract 2880 from 2915 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Let's proceed to step 9:
If we divide 350 by 320, we get 1 and a remainder of 30.
The number 1 becomes the next digit in our result. 
Result so far: 272499.1
Deduct 320 from 350 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 10:
320 goes into 300 0 times with a remainder of 300.
The next digit of our result is 0. 
Result so far: 272499.1
Subtracting 0 from 300 leaves us with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Advancing to step 11:
3000 divided by 320 is 9 with a remainder of 120.
Record the quotient 9 as the next digit in the result. 
Result so far: 272499.109
The remainder is 120 after subtracting 2880 from 3000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Let's proceed to step 12:
If we divide 1200 by 320, we get 3 and a remainder of 240.
Put 3 as the next digit of the answer. 
Result so far: 272499.1093
The remainder is 240 after subtracting 960 from 1200.
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 13:
2400 divided by 320 is 7 with a remainder of 160.
Record the quotient 7 as the next digit in the result. 
Result so far: 272499.10937
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.

Advancing to step 14:
320 can be fit into 1600 5 times, resulting in a remainder of 0.
The next digit of our result is 5. 
Result so far: 272499.109375
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.

Going ahead to step 15:
320 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 272499.109375
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.

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: 272499.109375
Subtracting 0 from 0 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.

The final result is 272499.109375 with a remainder of 0.0.
