We look at the division of 343407 by 70 
Our goal is to divide 343407 by 70.

Moving on to step 1:
70 can be fit into 3 0 times, resulting in a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Grab the next digit (4) from the dividend, add it to 3, then carry on: 34 / 70

Advancing to step 2:
34 divided by 70 is 0 with a remainder of 34.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 34, we get 34.
Append the next digit (3) from the dividend to 34 and continue with: 343 / 70

Moving on to step 3:
70 can be fit into 343 4 times, resulting in a remainder of 63.
Put 4 as the next digit of the answer. 
Result so far: 4.0
If we take 280 away from 343, we end up with 63.
Fetch the next digit (4) from the dividend, attach it to 63 and continue: 634 / 70

Step 4:
70 can be fit into 634 9 times, resulting in a remainder of 4.
The next digit of our result is 9. 
Result so far: 49.0
Subtracting 630 from 634 leaves us with 4.
Fetch the next digit (0) from the dividend, attach it to 4 and continue: 40 / 70

On to step 5:
70 can be fit into 40 0 times, resulting in a remainder of 40.
The next digit of our result is 0. 
Result so far: 490.0
Subtracting 0 from 40 leaves us with 40.
Include the next digit (7) from the dividend after 40, then repeat: 407 / 70

Advancing to step 6:
If we divide 407 by 70, we get 5 and a remainder of 57.
Use 5 as the next digit of our solution. 
Result so far: 4905.0
If we take 350 away from 407, we end up with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

On to step 7:
The number 70 fits into 570 8 times, leaving a remainder of 10.
The number 8 becomes the next digit in our result. 
Result so far: 4905.8
Deduct 560 from 570 and we're left 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.

On to step 8:
100 divided by 70 is 1 with a remainder of 30.
Use 1 as the next digit of our solution. 
Result so far: 4905.81
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 9:
300 divided by 70 is 4 with a remainder of 20.
Use 4 as the next digit of our solution. 
Result so far: 4905.814
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.

On to step 10:
If we divide 200 by 70, we get 2 and a remainder of 60.
The number 2 becomes the next digit in our result. 
Result so far: 4905.8142
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 11:
The number 70 fits into 600 8 times, leaving a remainder of 40.
The number 8 becomes the next digit in our result. 
Result so far: 4905.81428
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 12:
If we divide 400 by 70, we get 5 and a remainder of 50.
The next digit of our result is 5. 
Result so far: 4905.814285
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.

Advancing to step 13:
70 goes into 500 7 times with a remainder of 10.
Record the quotient 7 as the next digit in the result. 
Result so far: 4905.8142857
Subtract 490 from 500 to 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 14:
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: 4905.81428571
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.

In conclusion, the division gives 4905.81428571 with a balance of 3e-08.
