We look at the division of 85808857 by 343 
We're looking to find how many times 343 goes into 85808857.

Advancing to step 1:
If we divide 8 by 343, we get 0 and a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Take the next digit (5) from the dividend and append it to 8, then repeat: 85 / 343

Let's proceed to step 2:
85 divided by 343 is 0 with a remainder of 85.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 85 leaves us with 85.
Fetch the next digit (8) from the dividend, attach it to 85 and continue: 858 / 343

On to step 3:
The number 343 fits into 858 2 times, leaving a remainder of 172.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtracting 686 from 858 leaves us with 172.
Include the next digit (0) from the dividend after 172, then repeat: 1720 / 343

Going ahead to step 4:
343 goes into 1720 5 times with a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 25.0
Subtract 1715 from 1720 to get 5.
Include the next digit (8) from the dividend after 5, then repeat: 58 / 343

Step 5:
If we divide 58 by 343, we get 0 and a remainder of 58.
Write down 0 as next digit of the result. 
Result so far: 250.0
Subtract 0 from 58 to get 58.
Fetch the next digit (8) from the dividend, attach it to 58 and continue: 588 / 343

Step 6:
If we divide 588 by 343, we get 1 and a remainder of 245.
The number 1 becomes the next digit in our result. 
Result so far: 2501.0
The remainder is 245 after subtracting 343 from 588.
Include the next digit (5) from the dividend after 245, then repeat: 2455 / 343

Let's proceed to step 7:
2455 divided by 343 is 7 with a remainder of 54.
Put 7 as the next digit of the answer. 
Result so far: 25017.0
If we subtract 2401 from 2455, we get 54.
Bring next digit (7) of the dividend behind the 54 and repeat the process: 547 / 343

Advancing to step 8:
547 divided by 343 is 1 with a remainder of 204.
Record the quotient 1 as the next digit in the result. 
Result so far: 250171.0
If we take 343 away from 547, we end up with 204.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2040, and continue the process.

Advancing to step 9:
343 goes into 2040 5 times with a remainder of 325.
Use 5 as the next digit of our solution. 
Result so far: 250171.5
Subtract 1715 from 2040 to get 325.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3250, and continue the process.

Moving on to step 10:
343 can be fit into 3250 9 times, resulting in a remainder of 163.
Put 9 as the next digit of the answer. 
Result so far: 250171.59
If we subtract 3087 from 3250, we get 163.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1630, and continue the process.

On to step 11:
1630 divided by 343 is 4 with a remainder of 258.
Record the quotient 4 as the next digit in the result. 
Result so far: 250171.594
Deduct 1372 from 1630 and we're left with 258.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2580, and continue the process.

Advancing to step 12:
The number 343 fits into 2580 7 times, leaving a remainder of 179.
Put 7 as the next digit of the answer. 
Result so far: 250171.5947
Subtract 2401 from 2580 to get 179.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1790, and continue the process.

On to step 13:
If we divide 1790 by 343, we get 5 and a remainder of 75.
Use 5 as the next digit of our solution. 
Result so far: 250171.59475
Deduct 1715 from 1790 and we're left with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Moving on to step 14:
If we divide 750 by 343, we get 2 and a remainder of 64.
The next digit of our result is 2. 
Result so far: 250171.594752
Subtract 686 from 750 to get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Advancing to step 15:
The number 343 fits into 640 1 times, leaving a remainder of 297.
The number 1 becomes the next digit in our result. 
Result so far: 250171.5947521
If we subtract 343 from 640, we get 297.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2970, and continue the process.

On to step 16:
2970 divided by 343 is 8 with a remainder of 226.
Put 8 as the next digit of the answer. 
Result so far: 250171.59475218
The remainder is 226 after subtracting 2744 from 2970.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2260, and continue the process.

Our division results in 250171.59475218 with a remaining 2.26e-07.
