We divide 343609 by 89
Our goal is to divide 343609 by 89.

Advancing to step 1:
89 can be fit into 3 0 times, resulting in a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Include the next digit (4) from the dividend after 3, then repeat: 34 / 89

Going ahead to step 2:
89 goes into 34 0 times with a remainder of 34.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 34 leaves us with 34.
Fetch the next digit (3) from the dividend, attach it to 34 and continue: 343 / 89

Moving on to step 3:
343 divided by 89 is 3 with a remainder of 76.
Put 3 as the next digit of the answer. 
Result so far: 3.0
The remainder is 76 after subtracting 267 from 343.
Grab the next digit (6) from the dividend, add it to 76, then carry on: 766 / 89

On to step 4:
766 divided by 89 is 8 with a remainder of 54.
Write down 8 as next digit of the result. 
Result so far: 38.0
Subtract 712 from 766 to get 54.
Grab the next digit (0) from the dividend, add it to 54, then carry on: 540 / 89

On to step 5:
The number 89 fits into 540 6 times, leaving a remainder of 6.
Use 6 as the next digit of our solution. 
Result so far: 386.0
Deduct 534 from 540 and we're left with 6.
Bring next digit (9) of the dividend behind the 6 and repeat the process: 69 / 89

Going ahead to step 6:
89 goes into 69 0 times with a remainder of 69.
The next digit of our result is 0. 
Result so far: 3860.0
The remainder is 69 after subtracting 0 from 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Going ahead to step 7:
89 goes into 690 7 times with a remainder of 67.
The next digit of our result is 7. 
Result so far: 3860.7
If we take 623 away from 690, we end up with 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Let's proceed to step 8:
89 goes into 670 7 times with a remainder of 47.
Put 7 as the next digit of the answer. 
Result so far: 3860.77
Deduct 623 from 670 and we're left with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

After the division, we end up with 3860.77 and a remainder of 0.047.
