We look at the division of 23687 by 70 
Our goal is to divide 23687 by 70.

Step 1:
70 goes into 2 0 times with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Include the next digit (3) from the dividend after 2, then repeat: 23 / 70

Going ahead to step 2:
When dividing 23 by 70, we get 0 with a remainder of 23.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 23 leaves us with 23.
Take the next digit (6) from the dividend and append it to 23, then repeat: 236 / 70

On to step 3:
If we divide 236 by 70, we get 3 and a remainder of 26.
Write down 3 as next digit of the result. 
Result so far: 3.0
Deduct 210 from 236 and we're left with 26.
Take the next digit (8) from the dividend and append it to 26, then repeat: 268 / 70

Let's proceed to step 4:
The number 70 fits into 268 3 times, leaving a remainder of 58.
Use 3 as the next digit of our solution. 
Result so far: 33.0
If we take 210 away from 268, we end up with 58.
Append the next digit (7) from the dividend to 58 and continue with: 587 / 70

Going ahead to step 5:
587 divided by 70 is 8 with a remainder of 27.
Write down 8 as next digit of the result. 
Result so far: 338.0
If we take 560 away from 587, we end up with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Let's proceed to step 6:
The number 70 fits into 270 3 times, leaving a remainder of 60.
Put 3 as the next digit of the answer. 
Result so far: 338.3
Deduct 210 from 270 and we're left with 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 7:
70 goes into 600 8 times with a remainder of 40.
The next digit of our result is 8. 
Result so far: 338.38
The remainder is 40 after subtracting 560 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 8:
400 divided by 70 is 5 with a remainder of 50.
Write down 5 as next digit of the result. 
Result so far: 338.385
Subtract 350 from 400 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 9:
The number 70 fits into 500 7 times, leaving a remainder of 10.
The next digit of our result is 7. 
Result so far: 338.3857
If we take 490 away from 500, we end up 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.

Moving on to step 10:
100 divided by 70 is 1 with a remainder of 30.
The number 1 becomes the next digit in our result. 
Result so far: 338.38571
If we subtract 70 from 100, we get 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 11:
When dividing 300 by 70, we get 4 with a remainder of 20.
Put 4 as the next digit of the answer. 
Result so far: 338.385714
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.

Step 12:
200 divided by 70 is 2 with a remainder of 60.
The number 2 becomes the next digit in our result. 
Result so far: 338.3857142
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.

Step 13:
600 divided by 70 is 8 with a remainder of 40.
The next digit of our result is 8. 
Result so far: 338.38571428
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.

The final outcome is 338.38571428, with a leftover of 4e-08.
