Let's divide 85870325 by 280
We're looking to find how many times 280 goes into 85870325.

On to step 1:
8 divided by 280 is 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Grab the next digit (5) from the dividend, add it to 8, then carry on: 85 / 280

Step 2:
If we divide 85 by 280, we get 0 and a remainder of 85.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 85, we end up with 85.
Fetch the next digit (8) from the dividend, attach it to 85 and continue: 858 / 280

Going ahead to step 3:
858 divided by 280 is 3 with a remainder of 18.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we subtract 840 from 858, we get 18.
Append the next digit (7) from the dividend to 18 and continue with: 187 / 280

On to step 4:
The number 280 fits into 187 0 times, leaving a remainder of 187.
Put 0 as the next digit of the answer. 
Result so far: 30.0
The remainder is 187 after subtracting 0 from 187.
Bring next digit (0) of the dividend behind the 187 and repeat the process: 1870 / 280

Moving on to step 5:
The number 280 fits into 1870 6 times, leaving a remainder of 190.
The next digit of our result is 6. 
Result so far: 306.0
Subtracting 1680 from 1870 leaves us with 190.
Fetch the next digit (3) from the dividend, attach it to 190 and continue: 1903 / 280

Moving on to step 6:
When dividing 1903 by 280, we get 6 with a remainder of 223.
Use 6 as the next digit of our solution. 
Result so far: 3066.0
Deduct 1680 from 1903 and we're left with 223.
Grab the next digit (2) from the dividend, add it to 223, then carry on: 2232 / 280

Let's proceed to step 7:
When dividing 2232 by 280, we get 7 with a remainder of 272.
Put 7 as the next digit of the answer. 
Result so far: 30667.0
If we subtract 1960 from 2232, we get 272.
Fetch the next digit (5) from the dividend, attach it to 272 and continue: 2725 / 280

Moving on to step 8:
The number 280 fits into 2725 9 times, leaving a remainder of 205.
Write down 9 as next digit of the result. 
Result so far: 306679.0
Subtracting 2520 from 2725 leaves us with 205.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2050, and continue the process.

Going ahead to step 9:
When dividing 2050 by 280, we get 7 with a remainder of 90.
Write down 7 as next digit of the result. 
Result so far: 306679.7
Deduct 1960 from 2050 and we're left with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Step 10:
900 divided by 280 is 3 with a remainder of 60.
The next digit of our result is 3. 
Result so far: 306679.73
Subtract 840 from 900 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 11:
The number 280 fits into 600 2 times, leaving a remainder of 40.
Use 2 as the next digit of our solution. 
Result so far: 306679.732
If we take 560 away from 600, 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.

Going ahead to step 12:
If we divide 400 by 280, we get 1 and a remainder of 120.
Write down 1 as next digit of the result. 
Result so far: 306679.7321
Deduct 280 from 400 and we're left with 120.
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 13:
280 can be fit into 1200 4 times, resulting in a remainder of 80.
Write down 4 as next digit of the result. 
Result so far: 306679.73214
The remainder is 80 after subtracting 1120 from 1200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Moving on to step 14:
When dividing 800 by 280, we get 2 with a remainder of 240.
Write down 2 as next digit of the result. 
Result so far: 306679.732142
Subtract 560 from 800 to get 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 15:
280 goes into 2400 8 times with a remainder of 160.
Use 8 as the next digit of our solution. 
Result so far: 306679.7321428
Subtract 2240 from 2400 to 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.

Let's proceed to step 16:
280 can be fit into 1600 5 times, resulting in a remainder of 200.
Use 5 as the next digit of our solution. 
Result so far: 306679.73214285
The remainder is 200 after subtracting 1400 from 1600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

The final result is 306679.73214285 with a remainder of 2e-07.
