30812990 ÷ 948 
We want to figure out the number of times 30812990 can be divided by 948.

Moving on to step 1:
948 can be fit into 3 0 times, resulting in a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Take the next digit (0) from the dividend and append it to 3, then repeat: 30 / 948

Let's proceed to step 2:
If we divide 30 by 948, we get 0 and a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 30 after subtracting 0 from 30.
Include the next digit (8) from the dividend after 30, then repeat: 308 / 948

Advancing to step 3:
948 goes into 308 0 times with a remainder of 308.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 308 leaves us with 308.
Bring next digit (1) of the dividend behind the 308 and repeat the process: 3081 / 948

Going ahead to step 4:
The number 948 fits into 3081 3 times, leaving a remainder of 237.
Write down 3 as next digit of the result. 
Result so far: 3.0
The remainder is 237 after subtracting 2844 from 3081.
Take the next digit (2) from the dividend and append it to 237, then repeat: 2372 / 948

Let's proceed to step 5:
The number 948 fits into 2372 2 times, leaving a remainder of 476.
The number 2 becomes the next digit in our result. 
Result so far: 32.0
Subtract 1896 from 2372 to get 476.
Take the next digit (9) from the dividend and append it to 476, then repeat: 4769 / 948

Step 6:
4769 divided by 948 is 5 with a remainder of 29.
The number 5 becomes the next digit in our result. 
Result so far: 325.0
If we take 4740 away from 4769, we end up with 29.
Append the next digit (9) from the dividend to 29 and continue with: 299 / 948

Moving on to step 7:
948 can be fit into 299 0 times, resulting in a remainder of 299.
Put 0 as the next digit of the answer. 
Result so far: 3250.0
If we take 0 away from 299, we end up with 299.
Take the next digit (0) from the dividend and append it to 299, then repeat: 2990 / 948

Going ahead to step 8:
The number 948 fits into 2990 3 times, leaving a remainder of 146.
The number 3 becomes the next digit in our result. 
Result so far: 32503.0
Subtract 2844 from 2990 to get 146.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1460, and continue the process.

Moving on to step 9:
When dividing 1460 by 948, we get 1 with a remainder of 512.
Write down 1 as next digit of the result. 
Result so far: 32503.1
Deduct 948 from 1460 and we're left with 512.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5120, and continue the process.

On to step 10:
5120 divided by 948 is 5 with a remainder of 380.
Put 5 as the next digit of the answer. 
Result so far: 32503.15
Subtract 4740 from 5120 to get 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Step 11:
The number 948 fits into 3800 4 times, leaving a remainder of 8.
Put 4 as the next digit of the answer. 
Result so far: 32503.154
The remainder is 8 after subtracting 3792 from 3800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 12:
948 goes into 80 0 times with a remainder of 80.
Put 0 as the next digit of the answer. 
Result so far: 32503.154
If we take 0 away from 80, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Going ahead to step 13:
If we divide 800 by 948, we get 0 and a remainder of 800.
Use 0 as the next digit of our solution. 
Result so far: 32503.154
If we take 0 away from 800, we end up with 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8000, and continue the process.

In conclusion, the division gives 32503.154 with a balance of 0.0008.
