We look at the division of 28990 by 70 
We're looking to find how many times 70 goes into 28990.

Let's proceed to step 1:
The number 70 fits into 2 0 times, leaving a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Include the next digit (8) from the dividend after 2, then repeat: 28 / 70

Going ahead to step 2:
70 goes into 28 0 times with a remainder of 28.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 28, we get 28.
Include the next digit (9) from the dividend after 28, then repeat: 289 / 70

Going ahead to step 3:
70 goes into 289 4 times with a remainder of 9.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Subtract 280 from 289 to get 9.
Append the next digit (9) from the dividend to 9 and continue with: 99 / 70

Going ahead to step 4:
If we divide 99 by 70, we get 1 and a remainder of 29.
The next digit of our result is 1. 
Result so far: 41.0
If we subtract 70 from 99, we get 29.
Take the next digit (0) from the dividend and append it to 29, then repeat: 290 / 70

Let's proceed to step 5:
The number 70 fits into 290 4 times, leaving a remainder of 10.
The number 4 becomes the next digit in our result. 
Result so far: 414.0
Subtracting 280 from 290 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 6:
When dividing 100 by 70, we get 1 with a remainder of 30.
Write down 1 as next digit of the result. 
Result so far: 414.1
Deduct 70 from 100 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.

Advancing to step 7:
70 can be fit into 300 4 times, resulting in a remainder of 20.
Use 4 as the next digit of our solution. 
Result so far: 414.14
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.

Step 8:
200 divided by 70 is 2 with a remainder of 60.
Use 2 as the next digit of our solution. 
Result so far: 414.142
Subtract 140 from 200 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.

On to step 9:
70 goes into 600 8 times with a remainder of 40.
Record the quotient 8 as the next digit in the result. 
Result so far: 414.1428
Subtract 560 from 600 to get 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 10:
The number 70 fits into 400 5 times, leaving a remainder of 50.
Put 5 as the next digit of the answer. 
Result so far: 414.14285
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.

Let's proceed to step 11:
When dividing 500 by 70, we get 7 with a remainder of 10.
The number 7 becomes the next digit in our result. 
Result so far: 414.142857
If we subtract 490 from 500, we 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.

Step 12:
If we divide 100 by 70, we get 1 and a remainder of 30.
Put 1 as the next digit of the answer. 
Result so far: 414.1428571
If we take 70 away from 100, 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.

Step 13:
70 can be fit into 300 4 times, resulting in a remainder of 20.
Use 4 as the next digit of our solution. 
Result so far: 414.14285714
The remainder is 20 after subtracting 280 from 300.
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 result is 414.14285714 with a remainder of 2e-08.
