30035143 ÷ 346 
We want to figure out the number of times 30035143 can be divided by 346.

Advancing to step 1:
346 can be fit into 3 0 times, resulting in a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Take the next digit (0) from the dividend and append it to 3, then repeat: 30 / 346

Step 2:
If we divide 30 by 346, we get 0 and a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 30 after subtracting 0 from 30.
Append the next digit (0) from the dividend to 30 and continue with: 300 / 346

On to step 3:
346 goes into 300 0 times with a remainder of 300.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 300 to get 300.
Include the next digit (3) from the dividend after 300, then repeat: 3003 / 346

Moving on to step 4:
3003 divided by 346 is 8 with a remainder of 235.
Put 8 as the next digit of the answer. 
Result so far: 8.0
If we subtract 2768 from 3003, we get 235.
Bring next digit (5) of the dividend behind the 235 and repeat the process: 2355 / 346

On to step 5:
2355 divided by 346 is 6 with a remainder of 279.
Record the quotient 6 as the next digit in the result. 
Result so far: 86.0
The remainder is 279 after subtracting 2076 from 2355.
Bring next digit (1) of the dividend behind the 279 and repeat the process: 2791 / 346

Let's proceed to step 6:
346 can be fit into 2791 8 times, resulting in a remainder of 23.
The number 8 becomes the next digit in our result. 
Result so far: 868.0
Subtracting 2768 from 2791 leaves us with 23.
Append the next digit (4) from the dividend to 23 and continue with: 234 / 346

Going ahead to step 7:
When dividing 234 by 346, we get 0 with a remainder of 234.
The next digit of our result is 0. 
Result so far: 8680.0
If we take 0 away from 234, we end up with 234.
Fetch the next digit (3) from the dividend, attach it to 234 and continue: 2343 / 346

Step 8:
The number 346 fits into 2343 6 times, leaving a remainder of 267.
The number 6 becomes the next digit in our result. 
Result so far: 86806.0
Subtract 2076 from 2343 to get 267.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2670, and continue the process.

Moving on to step 9:
2670 divided by 346 is 7 with a remainder of 248.
Record the quotient 7 as the next digit in the result. 
Result so far: 86806.7
If we subtract 2422 from 2670, we get 248.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

Moving on to step 10:
346 can be fit into 2480 7 times, resulting in a remainder of 58.
Put 7 as the next digit of the answer. 
Result so far: 86806.77
Deduct 2422 from 2480 and we're left with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

The final outcome is 86806.77, with a leftover of 0.058.
