278883 ÷ 70 
Our goal is to divide 278883 by 70.

Going ahead to step 1:
2 divided by 70 is 0 with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Take the next digit (7) from the dividend and append it to 2, then repeat: 27 / 70

On to step 2:
The number 70 fits into 27 0 times, leaving a remainder of 27.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 27 after subtracting 0 from 27.
Grab the next digit (8) from the dividend, add it to 27, then carry on: 278 / 70

Advancing to step 3:
When dividing 278 by 70, we get 3 with a remainder of 68.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Subtract 210 from 278 to get 68.
Take the next digit (8) from the dividend and append it to 68, then repeat: 688 / 70

Advancing to step 4:
70 can be fit into 688 9 times, resulting in a remainder of 58.
The next digit of our result is 9. 
Result so far: 39.0
If we subtract 630 from 688, we get 58.
Take the next digit (8) from the dividend and append it to 58, then repeat: 588 / 70

Advancing to step 5:
588 divided by 70 is 8 with a remainder of 28.
Put 8 as the next digit of the answer. 
Result so far: 398.0
Subtracting 560 from 588 leaves us with 28.
Fetch the next digit (3) from the dividend, attach it to 28 and continue: 283 / 70

Going ahead to step 6:
If we divide 283 by 70, we get 4 and a remainder of 3.
Use 4 as the next digit of our solution. 
Result so far: 3984.0
The remainder is 3 after subtracting 280 from 283.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 7:
70 can be fit into 30 0 times, resulting in a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 3984.0
If we take 0 away from 30, we end up 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.

Let's proceed to step 8:
When dividing 300 by 70, we get 4 with a remainder of 20.
The number 4 becomes the next digit in our result. 
Result so far: 3984.04
If we subtract 280 from 300, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 9:
When dividing 200 by 70, we get 2 with a remainder of 60.
The next digit of our result is 2. 
Result so far: 3984.042
The remainder is 60 after subtracting 140 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 10:
When dividing 600 by 70, we get 8 with a remainder of 40.
Write down 8 as next digit of the result. 
Result so far: 3984.0428
Deduct 560 from 600 and we're left 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.

On to step 11:
70 can be fit into 400 5 times, resulting in a remainder of 50.
Write down 5 as next digit of the result. 
Result so far: 3984.04285
Subtracting 350 from 400 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 12:
70 can be fit into 500 7 times, resulting in a remainder of 10.
The number 7 becomes the next digit in our result. 
Result so far: 3984.042857
Subtract 490 from 500 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.

Going ahead to step 13:
The number 70 fits into 100 1 times, leaving a remainder of 30.
The number 1 becomes the next digit in our result. 
Result so far: 3984.0428571
Subtracting 70 from 100 leaves us 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.

Going ahead to step 14:
70 goes into 300 4 times with a remainder of 20.
Record the quotient 4 as the next digit in the result. 
Result so far: 3984.04285714
Subtract 280 from 300 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The final outcome is 3984.04285714, with a leftover of 2e-08.
