We divide 343440 by 70
Let's see how many times 70 fits into 343440.

Advancing to step 1:
70 can be fit into 3 0 times, resulting in a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Fetch the next digit (4) from the dividend, attach it to 3 and continue: 34 / 70

Going ahead to step 2:
If we divide 34 by 70, we get 0 and a remainder of 34.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 34 after subtracting 0 from 34.
Grab the next digit (3) from the dividend, add it to 34, then carry on: 343 / 70

On to step 3:
70 goes into 343 4 times with a remainder of 63.
Write down 4 as next digit of the result. 
Result so far: 4.0
If we take 280 away from 343, we end up with 63.
Take the next digit (4) from the dividend and append it to 63, then repeat: 634 / 70

Going ahead to step 4:
If we divide 634 by 70, we get 9 and a remainder of 4.
Use 9 as the next digit of our solution. 
Result so far: 49.0
Subtracting 630 from 634 leaves us with 4.
Bring next digit (4) of the dividend behind the 4 and repeat the process: 44 / 70

Going ahead to step 5:
If we divide 44 by 70, we get 0 and a remainder of 44.
Use 0 as the next digit of our solution. 
Result so far: 490.0
Deduct 0 from 44 and we're left with 44.
Fetch the next digit (0) from the dividend, attach it to 44 and continue: 440 / 70

On to step 6:
70 goes into 440 6 times with a remainder of 20.
Record the quotient 6 as the next digit in the result. 
Result so far: 4906.0
The remainder is 20 after subtracting 420 from 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 7:
70 goes into 200 2 times with a remainder of 60.
Record the quotient 2 as the next digit in the result. 
Result so far: 4906.2
Deduct 140 from 200 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.

Let's proceed to step 8:
70 goes into 600 8 times with a remainder of 40.
Use 8 as the next digit of our solution. 
Result so far: 4906.28
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.

Step 9:
70 can be fit into 400 5 times, resulting in a remainder of 50.
The next digit of our result is 5. 
Result so far: 4906.285
If we take 350 away from 400, we end up 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.

Advancing to step 10:
500 divided by 70 is 7 with a remainder of 10.
The next digit of our result is 7. 
Result so far: 4906.2857
The remainder is 10 after subtracting 490 from 500.
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 11:
If we divide 100 by 70, we get 1 and a remainder of 30.
The next digit of our result is 1. 
Result so far: 4906.28571
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.

Moving on to step 12:
70 goes into 300 4 times with a remainder of 20.
Use 4 as the next digit of our solution. 
Result so far: 4906.285714
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.

Advancing to step 13:
70 goes into 200 2 times with a remainder of 60.
Record the quotient 2 as the next digit in the result. 
Result so far: 4906.2857142
Deduct 140 from 200 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.

Let's proceed to step 14:
70 can be fit into 600 8 times, resulting in a remainder of 40.
The number 8 becomes the next digit in our result. 
Result so far: 4906.28571428
Subtracting 560 from 600 leaves us 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 result is 4906.28571428 with a remainder of 4e-08.
