We look at the division of 70817984 by 285 
Our goal is to divide 70817984 by 285.

On to step 1:
The number 285 fits into 7 0 times, leaving a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Take the next digit (0) from the dividend and append it to 7, then repeat: 70 / 285

Step 2:
285 can be fit into 70 0 times, resulting in a remainder of 70.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 70 to get 70.
Fetch the next digit (8) from the dividend, attach it to 70 and continue: 708 / 285

Step 3:
708 divided by 285 is 2 with a remainder of 138.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we take 570 away from 708, we end up with 138.
Grab the next digit (1) from the dividend, add it to 138, then carry on: 1381 / 285

Going ahead to step 4:
285 goes into 1381 4 times with a remainder of 241.
The next digit of our result is 4. 
Result so far: 24.0
Subtracting 1140 from 1381 leaves us with 241.
Take the next digit (7) from the dividend and append it to 241, then repeat: 2417 / 285

Step 5:
If we divide 2417 by 285, we get 8 and a remainder of 137.
The next digit of our result is 8. 
Result so far: 248.0
Deduct 2280 from 2417 and we're left with 137.
Take the next digit (9) from the dividend and append it to 137, then repeat: 1379 / 285

Step 6:
1379 divided by 285 is 4 with a remainder of 239.
Write down 4 as next digit of the result. 
Result so far: 2484.0
The remainder is 239 after subtracting 1140 from 1379.
Append the next digit (8) from the dividend to 239 and continue with: 2398 / 285

Moving on to step 7:
When dividing 2398 by 285, we get 8 with a remainder of 118.
Put 8 as the next digit of the answer. 
Result so far: 24848.0
Deduct 2280 from 2398 and we're left with 118.
Fetch the next digit (4) from the dividend, attach it to 118 and continue: 1184 / 285

Let's proceed to step 8:
1184 divided by 285 is 4 with a remainder of 44.
The number 4 becomes the next digit in our result. 
Result so far: 248484.0
If we take 1140 away from 1184, we end up with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Advancing to step 9:
285 can be fit into 440 1 times, resulting in a remainder of 155.
Put 1 as the next digit of the answer. 
Result so far: 248484.1
Subtracting 285 from 440 leaves us with 155.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1550, and continue the process.

Step 10:
When dividing 1550 by 285, we get 5 with a remainder of 125.
Use 5 as the next digit of our solution. 
Result so far: 248484.15
Subtracting 1425 from 1550 leaves us with 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

Advancing to step 11:
285 goes into 1250 4 times with a remainder of 110.
Write down 4 as next digit of the result. 
Result so far: 248484.154
If we take 1140 away from 1250, we end up with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Step 12:
If we divide 1100 by 285, we get 3 and a remainder of 245.
The next digit of our result is 3. 
Result so far: 248484.1543
The remainder is 245 after subtracting 855 from 1100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2450, and continue the process.

Advancing to step 13:
285 can be fit into 2450 8 times, resulting in a remainder of 170.
Write down 8 as next digit of the result. 
Result so far: 248484.15438
Subtracting 2280 from 2450 leaves us with 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Let's proceed to step 14:
If we divide 1700 by 285, we get 5 and a remainder of 275.
Write down 5 as next digit of the result. 
Result so far: 248484.154385
Subtract 1425 from 1700 to get 275.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2750, and continue the process.

On to step 15:
The number 285 fits into 2750 9 times, leaving a remainder of 185.
The next digit of our result is 9. 
Result so far: 248484.1543859
Subtract 2565 from 2750 to get 185.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1850, and continue the process.

Advancing to step 16:
285 can be fit into 1850 6 times, resulting in a remainder of 140.
The next digit of our result is 6. 
Result so far: 248484.15438596
If we subtract 1710 from 1850, we get 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

After the division, we end up with 248484.15438596 and a remainder of 1.4e-07.
