We look at the division of 19515853 by 343 
We want to divide 19515853 by 343.

Let's proceed to step 1:
343 goes into 1 0 times with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Grab the next digit (9) from the dividend, add it to 1, then carry on: 19 / 343

Step 2:
If we divide 19 by 343, we get 0 and a remainder of 19.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 19, we get 19.
Bring next digit (5) of the dividend behind the 19 and repeat the process: 195 / 343

On to step 3:
343 goes into 195 0 times with a remainder of 195.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 195 after subtracting 0 from 195.
Append the next digit (1) from the dividend to 195 and continue with: 1951 / 343

Let's proceed to step 4:
When dividing 1951 by 343, we get 5 with a remainder of 236.
Use 5 as the next digit of our solution. 
Result so far: 5.0
If we take 1715 away from 1951, we end up with 236.
Take the next digit (5) from the dividend and append it to 236, then repeat: 2365 / 343

Let's proceed to step 5:
343 goes into 2365 6 times with a remainder of 307.
Write down 6 as next digit of the result. 
Result so far: 56.0
Subtracting 2058 from 2365 leaves us with 307.
Bring next digit (8) of the dividend behind the 307 and repeat the process: 3078 / 343

On to step 6:
The number 343 fits into 3078 8 times, leaving a remainder of 334.
Write down 8 as next digit of the result. 
Result so far: 568.0
If we take 2744 away from 3078, we end up with 334.
Bring next digit (5) of the dividend behind the 334 and repeat the process: 3345 / 343

Moving on to step 7:
343 goes into 3345 9 times with a remainder of 258.
Use 9 as the next digit of our solution. 
Result so far: 5689.0
The remainder is 258 after subtracting 3087 from 3345.
Grab the next digit (3) from the dividend, add it to 258, then carry on: 2583 / 343

On to step 8:
2583 divided by 343 is 7 with a remainder of 182.
The number 7 becomes the next digit in our result. 
Result so far: 56897.0
Subtract 2401 from 2583 to get 182.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1820, and continue the process.

Going ahead to step 9:
1820 divided by 343 is 5 with a remainder of 105.
The number 5 becomes the next digit in our result. 
Result so far: 56897.5
The remainder is 105 after subtracting 1715 from 1820.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

On to step 10:
1050 divided by 343 is 3 with a remainder of 21.
Put 3 as the next digit of the answer. 
Result so far: 56897.53
The remainder is 21 after subtracting 1029 from 1050.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Advancing to step 11:
343 goes into 210 0 times with a remainder of 210.
The next digit of our result is 0. 
Result so far: 56897.53
If we subtract 0 from 210, we get 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Going ahead to step 12:
343 goes into 2100 6 times with a remainder of 42.
Put 6 as the next digit of the answer. 
Result so far: 56897.5306
Deduct 2058 from 2100 and we're left with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Advancing to step 13:
If we divide 420 by 343, we get 1 and a remainder of 77.
The next digit of our result is 1. 
Result so far: 56897.53061
If we subtract 343 from 420, we get 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Going ahead to step 14:
343 goes into 770 2 times with a remainder of 84.
Use 2 as the next digit of our solution. 
Result so far: 56897.530612
The remainder is 84 after subtracting 686 from 770.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Going ahead to step 15:
343 goes into 840 2 times with a remainder of 154.
The next digit of our result is 2. 
Result so far: 56897.5306122
Deduct 686 from 840 and we're left with 154.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1540, and continue the process.

In conclusion, the division gives 56897.5306122 with a balance of 1.54e-06.
