30654298 ÷ 399 
Let's see how many times 399 fits into 30654298.

On to step 1:
3 divided by 399 is 0 with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Grab the next digit (0) from the dividend, add it to 3, then carry on: 30 / 399

Step 2:
399 goes into 30 0 times with a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 30 leaves us with 30.
Fetch the next digit (6) from the dividend, attach it to 30 and continue: 306 / 399

On to step 3:
399 goes into 306 0 times with a remainder of 306.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 306 to get 306.
Fetch the next digit (5) from the dividend, attach it to 306 and continue: 3065 / 399

On to step 4:
If we divide 3065 by 399, we get 7 and a remainder of 272.
Use 7 as the next digit of our solution. 
Result so far: 7.0
Subtracting 2793 from 3065 leaves us with 272.
Grab the next digit (4) from the dividend, add it to 272, then carry on: 2724 / 399

Advancing to step 5:
If we divide 2724 by 399, we get 6 and a remainder of 330.
Put 6 as the next digit of the answer. 
Result so far: 76.0
If we subtract 2394 from 2724, we get 330.
Fetch the next digit (2) from the dividend, attach it to 330 and continue: 3302 / 399

Moving on to step 6:
When dividing 3302 by 399, we get 8 with a remainder of 110.
The number 8 becomes the next digit in our result. 
Result so far: 768.0
The remainder is 110 after subtracting 3192 from 3302.
Fetch the next digit (9) from the dividend, attach it to 110 and continue: 1109 / 399

Step 7:
If we divide 1109 by 399, we get 2 and a remainder of 311.
Write down 2 as next digit of the result. 
Result so far: 7682.0
If we take 798 away from 1109, we end up with 311.
Append the next digit (8) from the dividend to 311 and continue with: 3118 / 399

Moving on to step 8:
399 can be fit into 3118 7 times, resulting in a remainder of 325.
Put 7 as the next digit of the answer. 
Result so far: 76827.0
If we take 2793 away from 3118, we end up with 325.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3250, and continue the process.

Let's proceed to step 9:
If we divide 3250 by 399, we get 8 and a remainder of 58.
Write down 8 as next digit of the result. 
Result so far: 76827.8
The remainder is 58 after subtracting 3192 from 3250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Let's proceed to step 10:
399 goes into 580 1 times with a remainder of 181.
The next digit of our result is 1. 
Result so far: 76827.81
If we take 399 away from 580, we end up with 181.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1810, and continue the process.

Step 11:
1810 divided by 399 is 4 with a remainder of 214.
Record the quotient 4 as the next digit in the result. 
Result so far: 76827.814
If we subtract 1596 from 1810, we get 214.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2140, and continue the process.

Advancing to step 12:
The number 399 fits into 2140 5 times, leaving a remainder of 145.
Record the quotient 5 as the next digit in the result. 
Result so far: 76827.8145
If we take 1995 away from 2140, we end up with 145.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

Going ahead to step 13:
When dividing 1450 by 399, we get 3 with a remainder of 253.
The next digit of our result is 3. 
Result so far: 76827.81453
Subtracting 1197 from 1450 leaves us with 253.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2530, and continue the process.

Step 14:
399 goes into 2530 6 times with a remainder of 136.
Write down 6 as next digit of the result. 
Result so far: 76827.814536
Deduct 2394 from 2530 and we're left with 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Advancing to step 15:
399 can be fit into 1360 3 times, resulting in a remainder of 163.
The next digit of our result is 3. 
Result so far: 76827.8145363
If we take 1197 away from 1360, we end up with 163.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1630, and continue the process.

On to step 16:
The number 399 fits into 1630 4 times, leaving a remainder of 34.
Write down 4 as next digit of the result. 
Result so far: 76827.81453634
Subtract 1596 from 1630 to get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

In conclusion, the division gives 76827.81453634 with a balance of 3.4e-08.
