We're dividing 3522724 by 343 
Let's see how many times 343 fits into 3522724.

Step 1:
When dividing 3 by 343, we get 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Grab the next digit (5) from the dividend, add it to 3, then carry on: 35 / 343

Let's proceed to step 2:
35 divided by 343 is 0 with a remainder of 35.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 35, we end up with 35.
Append the next digit (2) from the dividend to 35 and continue with: 352 / 343

Going ahead to step 3:
343 can be fit into 352 1 times, resulting in a remainder of 9.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 343 from 352 leaves us with 9.
Fetch the next digit (2) from the dividend, attach it to 9 and continue: 92 / 343

Step 4:
If we divide 92 by 343, we get 0 and a remainder of 92.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
If we take 0 away from 92, we end up with 92.
Append the next digit (7) from the dividend to 92 and continue with: 927 / 343

Moving on to step 5:
When dividing 927 by 343, we get 2 with a remainder of 241.
Use 2 as the next digit of our solution. 
Result so far: 102.0
The remainder is 241 after subtracting 686 from 927.
Bring next digit (2) of the dividend behind the 241 and repeat the process: 2412 / 343

Moving on to step 6:
If we divide 2412 by 343, we get 7 and a remainder of 11.
Record the quotient 7 as the next digit in the result. 
Result so far: 1027.0
Subtracting 2401 from 2412 leaves us with 11.
Bring next digit (4) of the dividend behind the 11 and repeat the process: 114 / 343

Advancing to step 7:
When dividing 114 by 343, we get 0 with a remainder of 114.
Use 0 as the next digit of our solution. 
Result so far: 10270.0
The remainder is 114 after subtracting 0 from 114.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

On to step 8:
The number 343 fits into 1140 3 times, leaving a remainder of 111.
Record the quotient 3 as the next digit in the result. 
Result so far: 10270.3
If we take 1029 away from 1140, we end up with 111.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1110, and continue the process.

Advancing to step 9:
The number 343 fits into 1110 3 times, leaving a remainder of 81.
The next digit of our result is 3. 
Result so far: 10270.33
If we subtract 1029 from 1110, we get 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

The final outcome is 10270.33, with a leftover of 0.081.
