30468389 ÷ 354 
Our goal is to divide 30468389 by 354.

Let's proceed to step 1:
If we divide 3 by 354, 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.
Grab the next digit (0) from the dividend, add it to 3, then carry on: 30 / 354

Advancing to step 2:
354 goes into 30 0 times with a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 30 leaves us with 30.
Grab the next digit (4) from the dividend, add it to 30, then carry on: 304 / 354

Step 3:
The number 354 fits into 304 0 times, leaving a remainder of 304.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 304, we end up with 304.
Take the next digit (6) from the dividend and append it to 304, then repeat: 3046 / 354

Moving on to step 4:
If we divide 3046 by 354, we get 8 and a remainder of 214.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Deduct 2832 from 3046 and we're left with 214.
Fetch the next digit (8) from the dividend, attach it to 214 and continue: 2148 / 354

Advancing to step 5:
The number 354 fits into 2148 6 times, leaving a remainder of 24.
The next digit of our result is 6. 
Result so far: 86.0
If we subtract 2124 from 2148, we get 24.
Bring next digit (3) of the dividend behind the 24 and repeat the process: 243 / 354

Step 6:
354 can be fit into 243 0 times, resulting in a remainder of 243.
Write down 0 as next digit of the result. 
Result so far: 860.0
Subtract 0 from 243 to get 243.
Take the next digit (8) from the dividend and append it to 243, then repeat: 2438 / 354

Moving on to step 7:
2438 divided by 354 is 6 with a remainder of 314.
Record the quotient 6 as the next digit in the result. 
Result so far: 8606.0
Subtracting 2124 from 2438 leaves us with 314.
Include the next digit (9) from the dividend after 314, then repeat: 3149 / 354

Step 8:
3149 divided by 354 is 8 with a remainder of 317.
The number 8 becomes the next digit in our result. 
Result so far: 86068.0
Deduct 2832 from 3149 and we're left with 317.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3170, and continue the process.

On to step 9:
The number 354 fits into 3170 8 times, leaving a remainder of 338.
The next digit of our result is 8. 
Result so far: 86068.8
If we take 2832 away from 3170, we end up with 338.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3380, and continue the process.

On to step 10:
354 can be fit into 3380 9 times, resulting in a remainder of 194.
The next digit of our result is 9. 
Result so far: 86068.89
The remainder is 194 after subtracting 3186 from 3380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1940, and continue the process.

Moving on to step 11:
354 can be fit into 1940 5 times, resulting in a remainder of 170.
The number 5 becomes the next digit in our result. 
Result so far: 86068.895
Deduct 1770 from 1940 and we're left with 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Advancing to step 12:
The number 354 fits into 1700 4 times, leaving a remainder of 284.
Write down 4 as next digit of the result. 
Result so far: 86068.8954
If we subtract 1416 from 1700, we get 284.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2840, and continue the process.

Step 13:
The number 354 fits into 2840 8 times, leaving a remainder of 8.
Record the quotient 8 as the next digit in the result. 
Result so far: 86068.89548
If we take 2832 away from 2840, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 14:
If we divide 80 by 354, we get 0 and a remainder of 80.
Record the quotient 0 as the next digit in the result. 
Result so far: 86068.89548
If we subtract 0 from 80, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Advancing to step 15:
354 can be fit into 800 2 times, resulting in a remainder of 92.
Put 2 as the next digit of the answer. 
Result so far: 86068.8954802
If we subtract 708 from 800, we get 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Step 16:
The number 354 fits into 920 2 times, leaving a remainder of 212.
Write down 2 as next digit of the result. 
Result so far: 86068.89548022
Deduct 708 from 920 and we're left with 212.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2120, and continue the process.

In conclusion, the division gives 86068.89548022 with a balance of 2.12e-07.
