We divide 23390 by 70
Let's see how many times 70 fits into 23390.

On to 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
If we subtract 0 from 2, we get 2.
Include the next digit (3) from the dividend after 2, then repeat: 23 / 70

Going ahead to step 2:
23 divided by 70 is 0 with a remainder of 23.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 23 to get 23.
Include the next digit (3) from the dividend after 23, then repeat: 233 / 70

Moving on to step 3:
The number 70 fits into 233 3 times, leaving a remainder of 23.
The next digit of our result is 3. 
Result so far: 3.0
Subtract 210 from 233 to get 23.
Grab the next digit (9) from the dividend, add it to 23, then carry on: 239 / 70

Let's proceed to step 4:
If we divide 239 by 70, we get 3 and a remainder of 29.
The number 3 becomes the next digit in our result. 
Result so far: 33.0
The remainder is 29 after subtracting 210 from 239.
Bring next digit (0) of the dividend behind the 29 and repeat the process: 290 / 70

Step 5:
The number 70 fits into 290 4 times, leaving a remainder of 10.
Write down 4 as next digit of the result. 
Result so far: 334.0
If we subtract 280 from 290, 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.

Let's proceed to step 6:
70 goes into 100 1 times with a remainder of 30.
Use 1 as the next digit of our solution. 
Result so far: 334.1
The remainder is 30 after subtracting 70 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 7:
70 can be fit into 300 4 times, resulting in a remainder of 20.
Put 4 as the next digit of the answer. 
Result so far: 334.14
Deduct 280 from 300 and we're left with 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 8:
200 divided by 70 is 2 with a remainder of 60.
Record the quotient 2 as the next digit in the result. 
Result so far: 334.142
If we take 140 away from 200, we end up 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 9:
The number 70 fits into 600 8 times, leaving a remainder of 40.
Write down 8 as next digit of the result. 
Result so far: 334.1428
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.

Moving on to step 10:
When dividing 400 by 70, we get 5 with a remainder of 50.
Record the quotient 5 as the next digit in the result. 
Result so far: 334.14285
Deduct 350 from 400 and we're left 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.

Going ahead to step 11:
500 divided by 70 is 7 with a remainder of 10.
The number 7 becomes the next digit in our result. 
Result so far: 334.142857
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.

Advancing to step 12:
70 can be fit into 100 1 times, resulting in a remainder of 30.
Write down 1 as next digit of the result. 
Result so far: 334.1428571
Subtract 70 from 100 to 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.

Let's proceed to step 13:
The number 70 fits into 300 4 times, leaving a remainder of 20.
Use 4 as the next digit of our solution. 
Result so far: 334.14285714
Subtracting 280 from 300 leaves us with 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 result is 334.14285714 with a remainder of 2e-08.
