We look at the division of 343699 by 58 
Our goal is to divide 343699 by 58.

Step 1:
58 goes into 3 0 times with 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.
Bring next digit (4) of the dividend behind the 3 and repeat the process: 34 / 58

Moving on to step 2:
The number 58 fits into 34 0 times, leaving a remainder of 34.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 34, we get 34.
Grab the next digit (3) from the dividend, add it to 34, then carry on: 343 / 58

Going ahead to step 3:
343 divided by 58 is 5 with a remainder of 53.
Put 5 as the next digit of the answer. 
Result so far: 5.0
Deduct 290 from 343 and we're left with 53.
Take the next digit (6) from the dividend and append it to 53, then repeat: 536 / 58

On to step 4:
The number 58 fits into 536 9 times, leaving a remainder of 14.
Record the quotient 9 as the next digit in the result. 
Result so far: 59.0
The remainder is 14 after subtracting 522 from 536.
Bring next digit (9) of the dividend behind the 14 and repeat the process: 149 / 58

Moving on to step 5:
149 divided by 58 is 2 with a remainder of 33.
The number 2 becomes the next digit in our result. 
Result so far: 592.0
The remainder is 33 after subtracting 116 from 149.
Include the next digit (9) from the dividend after 33, then repeat: 339 / 58

Moving on to step 6:
58 goes into 339 5 times with a remainder of 49.
The next digit of our result is 5. 
Result so far: 5925.0
If we subtract 290 from 339, we get 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Step 7:
490 divided by 58 is 8 with a remainder of 26.
Record the quotient 8 as the next digit in the result. 
Result so far: 5925.8
Deduct 464 from 490 and we're left with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

On to step 8:
The number 58 fits into 260 4 times, leaving a remainder of 28.
Put 4 as the next digit of the answer. 
Result so far: 5925.84
Subtracting 232 from 260 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

On to step 9:
The number 58 fits into 280 4 times, leaving a remainder of 48.
Put 4 as the next digit of the answer. 
Result so far: 5925.844
If we subtract 232 from 280, 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 quotient of the division is 5925.844, and the remainder is 0.0048.
