31313552 ÷ 343 
Our goal is to divide 31313552 by 343.

Advancing to step 1:
When dividing 3 by 343, we get 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Include the next digit (1) from the dividend after 3, then repeat: 31 / 343

Let's proceed to step 2:
When dividing 31 by 343, we get 0 with a remainder of 31.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 31, we get 31.
Fetch the next digit (3) from the dividend, attach it to 31 and continue: 313 / 343

Advancing to step 3:
343 can be fit into 313 0 times, resulting in a remainder of 313.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 313, we get 313.
Take the next digit (1) from the dividend and append it to 313, then repeat: 3131 / 343

Advancing to step 4:
The number 343 fits into 3131 9 times, leaving a remainder of 44.
Use 9 as the next digit of our solution. 
Result so far: 9.0
Subtracting 3087 from 3131 leaves us with 44.
Include the next digit (3) from the dividend after 44, then repeat: 443 / 343

Step 5:
The number 343 fits into 443 1 times, leaving a remainder of 100.
The next digit of our result is 1. 
Result so far: 91.0
Subtracting 343 from 443 leaves us with 100.
Include the next digit (5) from the dividend after 100, then repeat: 1005 / 343

Moving on to step 6:
343 goes into 1005 2 times with a remainder of 319.
Put 2 as the next digit of the answer. 
Result so far: 912.0
Deduct 686 from 1005 and we're left with 319.
Append the next digit (5) from the dividend to 319 and continue with: 3195 / 343

On to step 7:
The number 343 fits into 3195 9 times, leaving a remainder of 108.
The next digit of our result is 9. 
Result so far: 9129.0
If we subtract 3087 from 3195, we get 108.
Include the next digit (2) from the dividend after 108, then repeat: 1082 / 343

Moving on to step 8:
When dividing 1082 by 343, we get 3 with a remainder of 53.
The next digit of our result is 3. 
Result so far: 91293.0
Subtract 1029 from 1082 to get 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Step 9:
The number 343 fits into 530 1 times, leaving a remainder of 187.
The number 1 becomes the next digit in our result. 
Result so far: 91293.1
The remainder is 187 after subtracting 343 from 530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1870, and continue the process.

Going ahead to step 10:
343 can be fit into 1870 5 times, resulting in a remainder of 155.
Put 5 as the next digit of the answer. 
Result so far: 91293.15
If we take 1715 away from 1870, we end up with 155.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1550, and continue the process.

Going ahead to step 11:
When dividing 1550 by 343, we get 4 with a remainder of 178.
Use 4 as the next digit of our solution. 
Result so far: 91293.154
Deduct 1372 from 1550 and we're left with 178.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1780, and continue the process.

Step 12:
The number 343 fits into 1780 5 times, leaving a remainder of 65.
The number 5 becomes the next digit in our result. 
Result so far: 91293.1545
Subtract 1715 from 1780 to get 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

On to step 13:
343 can be fit into 650 1 times, resulting in a remainder of 307.
The next digit of our result is 1. 
Result so far: 91293.15451
If we take 343 away from 650, we end up with 307.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3070, and continue the process.

Moving on to step 14:
If we divide 3070 by 343, we get 8 and a remainder of 326.
Use 8 as the next digit of our solution. 
Result so far: 91293.154518
Subtract 2744 from 3070 to get 326.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3260, and continue the process.

Let's proceed to step 15:
343 can be fit into 3260 9 times, resulting in a remainder of 173.
The next digit of our result is 9. 
Result so far: 91293.1545189
Subtract 3087 from 3260 to get 173.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1730, and continue the process.

Let's proceed to step 16:
The number 343 fits into 1730 5 times, leaving a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 91293.15451895
If we take 1715 away from 1730, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

The final result is 91293.15451895 with a remainder of 1.5e-08.
