Let's divide 30561189 by 312
We want to figure out the number of times 30561189 can be divided by 312.

Advancing to step 1:
If we divide 3 by 312, we get 0 and a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Append the next digit (0) from the dividend to 3 and continue with: 30 / 312

Let's proceed to step 2:
When dividing 30 by 312, we get 0 with a remainder of 30.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 30, we end up with 30.
Bring next digit (5) of the dividend behind the 30 and repeat the process: 305 / 312

On to step 3:
305 divided by 312 is 0 with a remainder of 305.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 305 after subtracting 0 from 305.
Append the next digit (6) from the dividend to 305 and continue with: 3056 / 312

Let's proceed to step 4:
The number 312 fits into 3056 9 times, leaving a remainder of 248.
The next digit of our result is 9. 
Result so far: 9.0
If we subtract 2808 from 3056, we get 248.
Bring next digit (1) of the dividend behind the 248 and repeat the process: 2481 / 312

Moving on to step 5:
2481 divided by 312 is 7 with a remainder of 297.
Record the quotient 7 as the next digit in the result. 
Result so far: 97.0
Deduct 2184 from 2481 and we're left with 297.
Append the next digit (1) from the dividend to 297 and continue with: 2971 / 312

Advancing to step 6:
312 goes into 2971 9 times with a remainder of 163.
Record the quotient 9 as the next digit in the result. 
Result so far: 979.0
The remainder is 163 after subtracting 2808 from 2971.
Include the next digit (8) from the dividend after 163, then repeat: 1638 / 312

Moving on to step 7:
If we divide 1638 by 312, we get 5 and a remainder of 78.
Put 5 as the next digit of the answer. 
Result so far: 9795.0
The remainder is 78 after subtracting 1560 from 1638.
Append the next digit (9) from the dividend to 78 and continue with: 789 / 312

On to step 8:
312 can be fit into 789 2 times, resulting in a remainder of 165.
The number 2 becomes the next digit in our result. 
Result so far: 97952.0
Subtracting 624 from 789 leaves us with 165.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1650, and continue the process.

Moving on to step 9:
312 can be fit into 1650 5 times, resulting in a remainder of 90.
Put 5 as the next digit of the answer. 
Result so far: 97952.5
Subtract 1560 from 1650 to get 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Moving on to step 10:
312 goes into 900 2 times with a remainder of 276.
The next digit of our result is 2. 
Result so far: 97952.52
If we subtract 624 from 900, we get 276.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2760, and continue the process.

Advancing to step 11:
If we divide 2760 by 312, we get 8 and a remainder of 264.
The number 8 becomes the next digit in our result. 
Result so far: 97952.528
Subtracting 2496 from 2760 leaves us with 264.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2640, and continue the process.

Step 12:
312 can be fit into 2640 8 times, resulting in a remainder of 144.
Write down 8 as next digit of the result. 
Result so far: 97952.5288
If we subtract 2496 from 2640, we get 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

The final outcome is 97952.5288, with a leftover of 0.00144.
