30581573 ÷ 214 
We want to divide 30581573 by 214.

Going ahead to step 1:
3 divided by 214 is 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Append the next digit (0) from the dividend to 3 and continue with: 30 / 214

Let's proceed to step 2:
When dividing 30 by 214, we get 0 with a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 30 after subtracting 0 from 30.
Grab the next digit (5) from the dividend, add it to 30, then carry on: 305 / 214

Step 3:
The number 214 fits into 305 1 times, leaving a remainder of 91.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 214 from 305 and we're left with 91.
Include the next digit (8) from the dividend after 91, then repeat: 918 / 214

Advancing to step 4:
When dividing 918 by 214, we get 4 with a remainder of 62.
The next digit of our result is 4. 
Result so far: 14.0
Subtract 856 from 918 to get 62.
Grab the next digit (1) from the dividend, add it to 62, then carry on: 621 / 214

Step 5:
If we divide 621 by 214, we get 2 and a remainder of 193.
Use 2 as the next digit of our solution. 
Result so far: 142.0
Subtract 428 from 621 to get 193.
Fetch the next digit (5) from the dividend, attach it to 193 and continue: 1935 / 214

Advancing to step 6:
1935 divided by 214 is 9 with a remainder of 9.
Write down 9 as next digit of the result. 
Result so far: 1429.0
If we subtract 1926 from 1935, we get 9.
Append the next digit (7) from the dividend to 9 and continue with: 97 / 214

Going ahead to step 7:
If we divide 97 by 214, we get 0 and a remainder of 97.
The next digit of our result is 0. 
Result so far: 14290.0
Deduct 0 from 97 and we're left with 97.
Grab the next digit (3) from the dividend, add it to 97, then carry on: 973 / 214

Step 8:
When dividing 973 by 214, we get 4 with a remainder of 117.
Put 4 as the next digit of the answer. 
Result so far: 142904.0
Subtracting 856 from 973 leaves us with 117.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1170, and continue the process.

Step 9:
214 can be fit into 1170 5 times, resulting in a remainder of 100.
Use 5 as the next digit of our solution. 
Result so far: 142904.5
If we take 1070 away from 1170, we end up with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Let's proceed to step 10:
214 goes into 1000 4 times with a remainder of 144.
Record the quotient 4 as the next digit in the result. 
Result so far: 142904.54
Subtract 856 from 1000 to 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.

Moving on to step 11:
1440 divided by 214 is 6 with a remainder of 156.
Use 6 as the next digit of our solution. 
Result so far: 142904.546
Subtracting 1284 from 1440 leaves us with 156.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

Step 12:
When dividing 1560 by 214, we get 7 with a remainder of 62.
Use 7 as the next digit of our solution. 
Result so far: 142904.5467
Subtracting 1498 from 1560 leaves us with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Moving on to step 13:
When dividing 620 by 214, we get 2 with a remainder of 192.
The next digit of our result is 2. 
Result so far: 142904.54672
If we subtract 428 from 620, we get 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

Step 14:
214 can be fit into 1920 8 times, resulting in a remainder of 208.
Write down 8 as next digit of the result. 
Result so far: 142904.546728
Deduct 1712 from 1920 and we're left with 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

Let's proceed to step 15:
214 goes into 2080 9 times with a remainder of 154.
Use 9 as the next digit of our solution. 
Result so far: 142904.5467289
The remainder is 154 after subtracting 1926 from 2080.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1540, and continue the process.

Going ahead to step 16:
214 goes into 1540 7 times with a remainder of 42.
The number 7 becomes the next digit in our result. 
Result so far: 142904.54672897
If we subtract 1498 from 1540, we get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

After the division, we end up with 142904.54672897 and a remainder of 4.2e-08.
