30575115 ÷ 213 
We want to figure out the number of times 30575115 can be divided by 213.

Step 1:
If we divide 3 by 213, we get 0 and a remainder of 3.
Write down 0 as next digit of the result. 
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 / 213

Step 2:
When dividing 30 by 213, we get 0 with a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 30 to get 30.
Include the next digit (5) from the dividend after 30, then repeat: 305 / 213

Let's proceed to step 3:
305 divided by 213 is 1 with a remainder of 92.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 213 from 305 and we're left with 92.
Fetch the next digit (7) from the dividend, attach it to 92 and continue: 927 / 213

Step 4:
927 divided by 213 is 4 with a remainder of 75.
Record the quotient 4 as the next digit in the result. 
Result so far: 14.0
If we subtract 852 from 927, we get 75.
Include the next digit (5) from the dividend after 75, then repeat: 755 / 213

Let's proceed to step 5:
213 goes into 755 3 times with a remainder of 116.
The number 3 becomes the next digit in our result. 
Result so far: 143.0
Deduct 639 from 755 and we're left with 116.
Include the next digit (1) from the dividend after 116, then repeat: 1161 / 213

Moving on to step 6:
The number 213 fits into 1161 5 times, leaving a remainder of 96.
Record the quotient 5 as the next digit in the result. 
Result so far: 1435.0
Subtracting 1065 from 1161 leaves us with 96.
Grab the next digit (1) from the dividend, add it to 96, then carry on: 961 / 213

Step 7:
The number 213 fits into 961 4 times, leaving a remainder of 109.
Put 4 as the next digit of the answer. 
Result so far: 14354.0
If we subtract 852 from 961, we get 109.
Grab the next digit (5) from the dividend, add it to 109, then carry on: 1095 / 213

Advancing to step 8:
213 can be fit into 1095 5 times, resulting in a remainder of 30.
The number 5 becomes the next digit in our result. 
Result so far: 143545.0
Subtract 1065 from 1095 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 9:
When dividing 300 by 213, we get 1 with a remainder of 87.
The number 1 becomes the next digit in our result. 
Result so far: 143545.1
Subtract 213 from 300 to get 87.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

Advancing to step 10:
870 divided by 213 is 4 with a remainder of 18.
Put 4 as the next digit of the answer. 
Result so far: 143545.14
Subtracting 852 from 870 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 11:
213 goes into 180 0 times with a remainder of 180.
Write down 0 as next digit of the result. 
Result so far: 143545.14
The remainder is 180 after subtracting 0 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Step 12:
213 goes into 1800 8 times with a remainder of 96.
Put 8 as the next digit of the answer. 
Result so far: 143545.1408
Subtracting 1704 from 1800 leaves us with 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Going ahead to step 13:
960 divided by 213 is 4 with a remainder of 108.
Record the quotient 4 as the next digit in the result. 
Result so far: 143545.14084
If we take 852 away from 960, we end up with 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Step 14:
The number 213 fits into 1080 5 times, leaving a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 143545.140845
Subtract 1065 from 1080 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 15:
When dividing 150 by 213, we get 0 with a remainder of 150.
Use 0 as the next digit of our solution. 
Result so far: 143545.140845
If we subtract 0 from 150, we get 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

On to step 16:
If we divide 1500 by 213, we get 7 and a remainder of 9.
Use 7 as the next digit of our solution. 
Result so far: 143545.14084507
Subtracting 1491 from 1500 leaves us with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

The final result is 143545.14084507 with a remainder of 9e-09.
