80373598 divided by 343 
Let's see how many times 343 fits into 80373598.

Going ahead to step 1:
8 divided by 343 is 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Grab the next digit (0) from the dividend, add it to 8, then carry on: 80 / 343

Going ahead to step 2:
The number 343 fits into 80 0 times, leaving a remainder of 80.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 80 after subtracting 0 from 80.
Include the next digit (3) from the dividend after 80, then repeat: 803 / 343

Moving on to step 3:
343 goes into 803 2 times with a remainder of 117.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
The remainder is 117 after subtracting 686 from 803.
Bring next digit (7) of the dividend behind the 117 and repeat the process: 1177 / 343

Going ahead to step 4:
1177 divided by 343 is 3 with a remainder of 148.
Record the quotient 3 as the next digit in the result. 
Result so far: 23.0
If we subtract 1029 from 1177, we get 148.
Take the next digit (3) from the dividend and append it to 148, then repeat: 1483 / 343

Going ahead to step 5:
1483 divided by 343 is 4 with a remainder of 111.
Write down 4 as next digit of the result. 
Result so far: 234.0
Subtracting 1372 from 1483 leaves us with 111.
Include the next digit (5) from the dividend after 111, then repeat: 1115 / 343

Advancing to step 6:
343 goes into 1115 3 times with a remainder of 86.
Record the quotient 3 as the next digit in the result. 
Result so far: 2343.0
Deduct 1029 from 1115 and we're left with 86.
Include the next digit (9) from the dividend after 86, then repeat: 869 / 343

Going ahead to step 7:
343 can be fit into 869 2 times, resulting in a remainder of 183.
The number 2 becomes the next digit in our result. 
Result so far: 23432.0
Deduct 686 from 869 and we're left with 183.
Include the next digit (8) from the dividend after 183, then repeat: 1838 / 343

Going ahead to step 8:
When dividing 1838 by 343, we get 5 with a remainder of 123.
Put 5 as the next digit of the answer. 
Result so far: 234325.0
If we subtract 1715 from 1838, we get 123.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1230, and continue the process.

Let's proceed to step 9:
343 can be fit into 1230 3 times, resulting in a remainder of 201.
Use 3 as the next digit of our solution. 
Result so far: 234325.3
The remainder is 201 after subtracting 1029 from 1230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2010, and continue the process.

Step 10:
2010 divided by 343 is 5 with a remainder of 295.
Use 5 as the next digit of our solution. 
Result so far: 234325.35
If we subtract 1715 from 2010, we get 295.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2950, and continue the process.

Moving on to step 11:
The number 343 fits into 2950 8 times, leaving a remainder of 206.
Write down 8 as next digit of the result. 
Result so far: 234325.358
Deduct 2744 from 2950 and we're left with 206.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2060, and continue the process.

Let's proceed to step 12:
When dividing 2060 by 343, we get 6 with a remainder of 2.
The number 6 becomes the next digit in our result. 
Result so far: 234325.3586
Subtract 2058 from 2060 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 13:
343 goes into 20 0 times with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 234325.3586
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 14:
343 goes into 200 0 times with a remainder of 200.
Use 0 as the next digit of our solution. 
Result so far: 234325.3586
Deduct 0 from 200 and we're left with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

The final outcome is 234325.3586, with a leftover of 2e-05.
