85670900 ÷ 288 
Our goal is to divide 85670900 by 288.

On to step 1:
8 divided by 288 is 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Grab the next digit (5) from the dividend, add it to 8, then carry on: 85 / 288

Moving on to step 2:
288 can be fit into 85 0 times, resulting in a remainder of 85.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 85 leaves us with 85.
Append the next digit (6) from the dividend to 85 and continue with: 856 / 288

Moving on to step 3:
The number 288 fits into 856 2 times, leaving a remainder of 280.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we subtract 576 from 856, we get 280.
Take the next digit (7) from the dividend and append it to 280, then repeat: 2807 / 288

Step 4:
288 goes into 2807 9 times with a remainder of 215.
The next digit of our result is 9. 
Result so far: 29.0
Subtract 2592 from 2807 to get 215.
Fetch the next digit (0) from the dividend, attach it to 215 and continue: 2150 / 288

Advancing to step 5:
288 can be fit into 2150 7 times, resulting in a remainder of 134.
Write down 7 as next digit of the result. 
Result so far: 297.0
Subtracting 2016 from 2150 leaves us with 134.
Append the next digit (9) from the dividend to 134 and continue with: 1349 / 288

Step 6:
The number 288 fits into 1349 4 times, leaving a remainder of 197.
The next digit of our result is 4. 
Result so far: 2974.0
Subtracting 1152 from 1349 leaves us with 197.
Grab the next digit (0) from the dividend, add it to 197, then carry on: 1970 / 288

Moving on to step 7:
If we divide 1970 by 288, we get 6 and a remainder of 242.
Write down 6 as next digit of the result. 
Result so far: 29746.0
If we take 1728 away from 1970, we end up with 242.
Take the next digit (0) from the dividend and append it to 242, then repeat: 2420 / 288

Going ahead to step 8:
If we divide 2420 by 288, we get 8 and a remainder of 116.
The number 8 becomes the next digit in our result. 
Result so far: 297468.0
Subtract 2304 from 2420 to get 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

Step 9:
The number 288 fits into 1160 4 times, leaving a remainder of 8.
Record the quotient 4 as the next digit in the result. 
Result so far: 297468.4
The remainder is 8 after subtracting 1152 from 1160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 10:
80 divided by 288 is 0 with a remainder of 80.
The number 0 becomes the next digit in our result. 
Result so far: 297468.4
If we subtract 0 from 80, we 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 11:
800 divided by 288 is 2 with a remainder of 224.
Write down 2 as next digit of the result. 
Result so far: 297468.402
Subtracting 576 from 800 leaves us with 224.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

Step 12:
288 goes into 2240 7 times with a remainder of 224.
Write down 7 as next digit of the result. 
Result so far: 297468.4027
The remainder is 224 after subtracting 2016 from 2240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

Let's proceed to step 13:
The number 288 fits into 2240 7 times, leaving a remainder of 224.
Put 7 as the next digit of the answer. 
Result so far: 297468.40277
If we subtract 2016 from 2240, we get 224.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

The final result is 297468.40277 with a remainder of 0.000224.
