We look at the division of 343657 by 79 
Let's see how many times 79 fits into 343657.

Advancing to step 1:
79 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.
Grab the next digit (4) from the dividend, add it to 3, then carry on: 34 / 79

Going ahead to step 2:
79 goes into 34 0 times with a remainder of 34.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 34 and we're left with 34.
Grab the next digit (3) from the dividend, add it to 34, then carry on: 343 / 79

Moving on to step 3:
The number 79 fits into 343 4 times, leaving a remainder of 27.
Write down 4 as next digit of the result. 
Result so far: 4.0
If we take 316 away from 343, we end up with 27.
Grab the next digit (6) from the dividend, add it to 27, then carry on: 276 / 79

Moving on to step 4:
If we divide 276 by 79, we get 3 and a remainder of 39.
Write down 3 as next digit of the result. 
Result so far: 43.0
If we take 237 away from 276, we end up with 39.
Grab the next digit (5) from the dividend, add it to 39, then carry on: 395 / 79

On to step 5:
395 divided by 79 is 5 with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 435.0
If we take 395 away from 395, we end up with 0.
Include the next digit (7) from the dividend after 0, then repeat: 7 / 79

On to step 6:
79 can be fit into 7 0 times, resulting in a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 4350.0
If we take 0 away from 7, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 7:
70 divided by 79 is 0 with a remainder of 70.
Put 0 as the next digit of the answer. 
Result so far: 4350.0
If we subtract 0 from 70, we get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Advancing to step 8:
79 goes into 700 8 times with a remainder of 68.
The number 8 becomes the next digit in our result. 
Result so far: 4350.08
If we take 632 away from 700, we end up with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Going ahead to step 9:
79 can be fit into 680 8 times, resulting in a remainder of 48.
Write down 8 as next digit of the result. 
Result so far: 4350.088
If we subtract 632 from 680, we get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

The final result is 4350.088 with a remainder of 0.0048.
