Let's divide 21434 by 70
Let's see how many times 70 fits into 21434.

Going ahead to step 1:
70 can be fit into 2 0 times, resulting in a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 70

Advancing to step 2:
21 divided by 70 is 0 with a remainder of 21.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 21 leaves us with 21.
Fetch the next digit (4) from the dividend, attach it to 21 and continue: 214 / 70

Let's proceed to step 3:
The number 70 fits into 214 3 times, leaving a remainder of 4.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
The remainder is 4 after subtracting 210 from 214.
Grab the next digit (3) from the dividend, add it to 4, then carry on: 43 / 70

Going ahead to step 4:
The number 70 fits into 43 0 times, leaving a remainder of 43.
Write down 0 as next digit of the result. 
Result so far: 30.0
If we take 0 away from 43, we end up with 43.
Take the next digit (4) from the dividend and append it to 43, then repeat: 434 / 70

Let's proceed to step 5:
The number 70 fits into 434 6 times, leaving a remainder of 14.
The next digit of our result is 6. 
Result so far: 306.0
Deduct 420 from 434 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 6:
When dividing 140 by 70, we get 2 with a remainder of 0.
Record the quotient 2 as the next digit in the result. 
Result so far: 306.2
If we subtract 140 from 140, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 7:
When dividing 0 by 70, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 306.2
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 8:
The number 70 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 306.2
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 306.2 with a remainder of 0.0.
