We look at the division of 84493639 by 343 
Let's see how many times 343 fits into 84493639.

Advancing to step 1:
The number 343 fits into 8 0 times, leaving a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Take the next digit (4) from the dividend and append it to 8, then repeat: 84 / 343

Step 2:
When dividing 84 by 343, we get 0 with a remainder of 84.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 84 and we're left with 84.
Bring next digit (4) of the dividend behind the 84 and repeat the process: 844 / 343

On to step 3:
When dividing 844 by 343, we get 2 with a remainder of 158.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we subtract 686 from 844, we get 158.
Grab the next digit (9) from the dividend, add it to 158, then carry on: 1589 / 343

Advancing to step 4:
343 goes into 1589 4 times with a remainder of 217.
Use 4 as the next digit of our solution. 
Result so far: 24.0
If we take 1372 away from 1589, we end up with 217.
Grab the next digit (3) from the dividend, add it to 217, then carry on: 2173 / 343

Let's proceed to step 5:
343 goes into 2173 6 times with a remainder of 115.
Record the quotient 6 as the next digit in the result. 
Result so far: 246.0
Deduct 2058 from 2173 and we're left with 115.
Bring next digit (6) of the dividend behind the 115 and repeat the process: 1156 / 343

Moving on to step 6:
The number 343 fits into 1156 3 times, leaving a remainder of 127.
Record the quotient 3 as the next digit in the result. 
Result so far: 2463.0
Subtracting 1029 from 1156 leaves us with 127.
Fetch the next digit (3) from the dividend, attach it to 127 and continue: 1273 / 343

Going ahead to step 7:
343 can be fit into 1273 3 times, resulting in a remainder of 244.
Use 3 as the next digit of our solution. 
Result so far: 24633.0
Deduct 1029 from 1273 and we're left with 244.
Fetch the next digit (9) from the dividend, attach it to 244 and continue: 2449 / 343

On to step 8:
343 goes into 2449 7 times with a remainder of 48.
Put 7 as the next digit of the answer. 
Result so far: 246337.0
If we take 2401 away from 2449, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Moving on to step 9:
480 divided by 343 is 1 with a remainder of 137.
Record the quotient 1 as the next digit in the result. 
Result so far: 246337.1
The remainder is 137 after subtracting 343 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1370, and continue the process.

On to step 10:
When dividing 1370 by 343, we get 3 with a remainder of 341.
Record the quotient 3 as the next digit in the result. 
Result so far: 246337.13
Subtracting 1029 from 1370 leaves us with 341.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3410, and continue the process.

Advancing to step 11:
When dividing 3410 by 343, we get 9 with a remainder of 323.
Use 9 as the next digit of our solution. 
Result so far: 246337.139
The remainder is 323 after subtracting 3087 from 3410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3230, and continue the process.

Going ahead to step 12:
If we divide 3230 by 343, we get 9 and a remainder of 143.
Record the quotient 9 as the next digit in the result. 
Result so far: 246337.1399
Subtract 3087 from 3230 to get 143.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1430, and continue the process.

The final outcome is 246337.1399, with a leftover of 0.00143.
