90430966 divided by 343 
We're looking to find how many times 343 goes into 90430966.

Step 1:
343 can be fit into 9 0 times, resulting in a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Include the next digit (0) from the dividend after 9, then repeat: 90 / 343

Moving on to step 2:
343 goes into 90 0 times with a remainder of 90.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 90, we get 90.
Append the next digit (4) from the dividend to 90 and continue with: 904 / 343

Let's proceed to step 3:
If we divide 904 by 343, we get 2 and a remainder of 218.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we take 686 away from 904, we end up with 218.
Take the next digit (3) from the dividend and append it to 218, then repeat: 2183 / 343

Step 4:
343 goes into 2183 6 times with a remainder of 125.
The number 6 becomes the next digit in our result. 
Result so far: 26.0
The remainder is 125 after subtracting 2058 from 2183.
Include the next digit (0) from the dividend after 125, then repeat: 1250 / 343

On to step 5:
If we divide 1250 by 343, we get 3 and a remainder of 221.
Use 3 as the next digit of our solution. 
Result so far: 263.0
If we take 1029 away from 1250, we end up with 221.
Append the next digit (9) from the dividend to 221 and continue with: 2219 / 343

On to step 6:
343 can be fit into 2219 6 times, resulting in a remainder of 161.
The next digit of our result is 6. 
Result so far: 2636.0
If we take 2058 away from 2219, we end up with 161.
Bring next digit (6) of the dividend behind the 161 and repeat the process: 1616 / 343

On to step 7:
343 can be fit into 1616 4 times, resulting in a remainder of 244.
Record the quotient 4 as the next digit in the result. 
Result so far: 26364.0
The remainder is 244 after subtracting 1372 from 1616.
Append the next digit (6) from the dividend to 244 and continue with: 2446 / 343

Moving on to step 8:
When dividing 2446 by 343, we get 7 with a remainder of 45.
Write down 7 as next digit of the result. 
Result so far: 263647.0
If we take 2401 away from 2446, we end up with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Going ahead to step 9:
343 goes into 450 1 times with a remainder of 107.
Record the quotient 1 as the next digit in the result. 
Result so far: 263647.1
If we take 343 away from 450, we end up with 107.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1070, and continue the process.

Going ahead to step 10:
343 can be fit into 1070 3 times, resulting in a remainder of 41.
Write down 3 as next digit of the result. 
Result so far: 263647.13
Subtracting 1029 from 1070 leaves us with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Going ahead to step 11:
410 divided by 343 is 1 with a remainder of 67.
Use 1 as the next digit of our solution. 
Result so far: 263647.131
Subtract 343 from 410 to get 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Going ahead to step 12:
When dividing 670 by 343, we get 1 with a remainder of 327.
Record the quotient 1 as the next digit in the result. 
Result so far: 263647.1311
If we subtract 343 from 670, we get 327.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3270, and continue the process.

The quotient of the division is 263647.1311, and the remainder is 0.00327.
