We look at the division of 58405970 by 343 
We want to divide 58405970 by 343.

Advancing to step 1:
The number 343 fits into 5 0 times, leaving a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Include the next digit (8) from the dividend after 5, then repeat: 58 / 343

Let's proceed to step 2:
343 can be fit into 58 0 times, resulting in a remainder of 58.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 58, we end up with 58.
Grab the next digit (4) from the dividend, add it to 58, then carry on: 584 / 343

On to step 3:
343 goes into 584 1 times with a remainder of 241.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 343 away from 584, we end up with 241.
Append the next digit (0) from the dividend to 241 and continue with: 2410 / 343

Going ahead to step 4:
343 goes into 2410 7 times with a remainder of 9.
Record the quotient 7 as the next digit in the result. 
Result so far: 17.0
Subtracting 2401 from 2410 leaves us with 9.
Bring next digit (5) of the dividend behind the 9 and repeat the process: 95 / 343

Going ahead to step 5:
The number 343 fits into 95 0 times, leaving a remainder of 95.
The next digit of our result is 0. 
Result so far: 170.0
Subtract 0 from 95 to get 95.
Include the next digit (9) from the dividend after 95, then repeat: 959 / 343

Going ahead to step 6:
959 divided by 343 is 2 with a remainder of 273.
Write down 2 as next digit of the result. 
Result so far: 1702.0
If we subtract 686 from 959, we get 273.
Append the next digit (7) from the dividend to 273 and continue with: 2737 / 343

Going ahead to step 7:
The number 343 fits into 2737 7 times, leaving a remainder of 336.
Put 7 as the next digit of the answer. 
Result so far: 17027.0
Subtracting 2401 from 2737 leaves us with 336.
Grab the next digit (0) from the dividend, add it to 336, then carry on: 3360 / 343

Advancing to step 8:
3360 divided by 343 is 9 with a remainder of 273.
The next digit of our result is 9. 
Result so far: 170279.0
Subtracting 3087 from 3360 leaves us with 273.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2730, and continue the process.

Step 9:
343 can be fit into 2730 7 times, resulting in a remainder of 329.
Use 7 as the next digit of our solution. 
Result so far: 170279.7
Subtract 2401 from 2730 to get 329.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3290, and continue the process.

Advancing to step 10:
The number 343 fits into 3290 9 times, leaving a remainder of 203.
The next digit of our result is 9. 
Result so far: 170279.79
Subtract 3087 from 3290 to get 203.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2030, and continue the process.

Advancing to step 11:
When dividing 2030 by 343, we get 5 with a remainder of 315.
Record the quotient 5 as the next digit in the result. 
Result so far: 170279.795
Subtract 1715 from 2030 to get 315.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3150, and continue the process.

Moving on to step 12:
The number 343 fits into 3150 9 times, leaving a remainder of 63.
The number 9 becomes the next digit in our result. 
Result so far: 170279.7959
If we take 3087 away from 3150, we end up with 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Let's proceed to step 13:
When dividing 630 by 343, we get 1 with a remainder of 287.
Write down 1 as next digit of the result. 
Result so far: 170279.79591
The remainder is 287 after subtracting 343 from 630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2870, and continue the process.

Let's proceed to step 14:
2870 divided by 343 is 8 with a remainder of 126.
The number 8 becomes the next digit in our result. 
Result so far: 170279.795918
Deduct 2744 from 2870 and we're left with 126.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

Advancing to step 15:
343 can be fit into 1260 3 times, resulting in a remainder of 231.
The number 3 becomes the next digit in our result. 
Result so far: 170279.7959183
Subtract 1029 from 1260 to get 231.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2310, and continue the process.

Let's proceed to step 16:
The number 343 fits into 2310 6 times, leaving a remainder of 252.
Write down 6 as next digit of the result. 
Result so far: 170279.79591836
Subtract 2058 from 2310 to get 252.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2520, and continue the process.

In conclusion, the division gives 170279.79591836 with a balance of 2.52e-07.
