54437105 divided by 343 
Let's see how many times 343 fits into 54437105.

On to step 1:
If we divide 5 by 343, we get 0 and a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Include the next digit (4) from the dividend after 5, then repeat: 54 / 343

Going ahead to step 2:
54 divided by 343 is 0 with a remainder of 54.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 54 after subtracting 0 from 54.
Grab the next digit (4) from the dividend, add it to 54, then carry on: 544 / 343

Going ahead to step 3:
343 can be fit into 544 1 times, resulting in a remainder of 201.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 201 after subtracting 343 from 544.
Bring next digit (3) of the dividend behind the 201 and repeat the process: 2013 / 343

Going ahead to step 4:
The number 343 fits into 2013 5 times, leaving a remainder of 298.
Put 5 as the next digit of the answer. 
Result so far: 15.0
Subtract 1715 from 2013 to get 298.
Take the next digit (7) from the dividend and append it to 298, then repeat: 2987 / 343

Step 5:
When dividing 2987 by 343, we get 8 with a remainder of 243.
The number 8 becomes the next digit in our result. 
Result so far: 158.0
Subtracting 2744 from 2987 leaves us with 243.
Include the next digit (1) from the dividend after 243, then repeat: 2431 / 343

Advancing to step 6:
When dividing 2431 by 343, we get 7 with a remainder of 30.
Write down 7 as next digit of the result. 
Result so far: 1587.0
If we subtract 2401 from 2431, we get 30.
Bring next digit (0) of the dividend behind the 30 and repeat the process: 300 / 343

Let's proceed to step 7:
If we divide 300 by 343, we get 0 and a remainder of 300.
Write down 0 as next digit of the result. 
Result so far: 15870.0
The remainder is 300 after subtracting 0 from 300.
Append the next digit (5) from the dividend to 300 and continue with: 3005 / 343

Step 8:
The number 343 fits into 3005 8 times, leaving a remainder of 261.
Write down 8 as next digit of the result. 
Result so far: 158708.0
Subtracting 2744 from 3005 leaves us with 261.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2610, and continue the process.

Step 9:
If we divide 2610 by 343, we get 7 and a remainder of 209.
Put 7 as the next digit of the answer. 
Result so far: 158708.7
The remainder is 209 after subtracting 2401 from 2610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2090, and continue the process.

Step 10:
If we divide 2090 by 343, we get 6 and a remainder of 32.
Record the quotient 6 as the next digit in the result. 
Result so far: 158708.76
Subtract 2058 from 2090 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 11:
When dividing 320 by 343, we get 0 with a remainder of 320.
Record the quotient 0 as the next digit in the result. 
Result so far: 158708.76
Subtract 0 from 320 to get 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Step 12:
If we divide 3200 by 343, we get 9 and a remainder of 113.
The number 9 becomes the next digit in our result. 
Result so far: 158708.7609
If we take 3087 away from 3200, we end up with 113.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1130, and continue the process.

Advancing to step 13:
1130 divided by 343 is 3 with a remainder of 101.
Write down 3 as next digit of the result. 
Result so far: 158708.76093
If we subtract 1029 from 1130, we get 101.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1010, and continue the process.

Advancing to step 14:
The number 343 fits into 1010 2 times, leaving a remainder of 324.
The number 2 becomes the next digit in our result. 
Result so far: 158708.760932
If we subtract 686 from 1010, we get 324.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3240, and continue the process.

Going ahead to step 15:
When dividing 3240 by 343, we get 9 with a remainder of 153.
The number 9 becomes the next digit in our result. 
Result so far: 158708.7609329
Deduct 3087 from 3240 and we're left with 153.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1530, and continue the process.

On to step 16:
The number 343 fits into 1530 4 times, leaving a remainder of 158.
The next digit of our result is 4. 
Result so far: 158708.76093294
Subtracting 1372 from 1530 leaves us with 158.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1580, and continue the process.

The final outcome is 158708.76093294, with a leftover of 1.58e-07.
