71286309 ÷ 213 
We're looking to find how many times 213 goes into 71286309.

Step 1:
213 can be fit into 7 0 times, resulting in a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Bring next digit (1) of the dividend behind the 7 and repeat the process: 71 / 213

Let's proceed to step 2:
213 goes into 71 0 times with a remainder of 71.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 71 and we're left with 71.
Fetch the next digit (2) from the dividend, attach it to 71 and continue: 712 / 213

Let's proceed to step 3:
When dividing 712 by 213, we get 3 with a remainder of 73.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtracting 639 from 712 leaves us with 73.
Append the next digit (8) from the dividend to 73 and continue with: 738 / 213

Moving on to step 4:
213 can be fit into 738 3 times, resulting in a remainder of 99.
Write down 3 as next digit of the result. 
Result so far: 33.0
If we subtract 639 from 738, we get 99.
Grab the next digit (6) from the dividend, add it to 99, then carry on: 996 / 213

Let's proceed to step 5:
996 divided by 213 is 4 with a remainder of 144.
The next digit of our result is 4. 
Result so far: 334.0
Subtract 852 from 996 to get 144.
Take the next digit (3) from the dividend and append it to 144, then repeat: 1443 / 213

Moving on to step 6:
The number 213 fits into 1443 6 times, leaving a remainder of 165.
Write down 6 as next digit of the result. 
Result so far: 3346.0
Deduct 1278 from 1443 and we're left with 165.
Take the next digit (0) from the dividend and append it to 165, then repeat: 1650 / 213

Let's proceed to step 7:
The number 213 fits into 1650 7 times, leaving a remainder of 159.
Use 7 as the next digit of our solution. 
Result so far: 33467.0
Deduct 1491 from 1650 and we're left with 159.
Include the next digit (9) from the dividend after 159, then repeat: 1599 / 213

Moving on to step 8:
1599 divided by 213 is 7 with a remainder of 108.
The number 7 becomes the next digit in our result. 
Result so far: 334677.0
Deduct 1491 from 1599 and we're left 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.

On to step 9:
When dividing 1080 by 213, we get 5 with a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 334677.5
Deduct 1065 from 1080 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 10:
213 goes into 150 0 times with a remainder of 150.
Record the quotient 0 as the next digit in the result. 
Result so far: 334677.5
Subtracting 0 from 150 leaves us with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Let's proceed to step 11:
213 goes into 1500 7 times with a remainder of 9.
The number 7 becomes the next digit in our result. 
Result so far: 334677.507
If we take 1491 away from 1500, we end up 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.

Advancing to step 12:
213 can be fit into 90 0 times, resulting in a remainder of 90.
Write down 0 as next digit of the result. 
Result so far: 334677.507
Subtract 0 from 90 to get 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

On to step 13:
The number 213 fits into 900 4 times, leaving a remainder of 48.
Use 4 as the next digit of our solution. 
Result so far: 334677.50704
The remainder is 48 after subtracting 852 from 900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Let's proceed to step 14:
When dividing 480 by 213, we get 2 with a remainder of 54.
Use 2 as the next digit of our solution. 
Result so far: 334677.507042
If we take 426 away from 480, we end up with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Going ahead to step 15:
If we divide 540 by 213, we get 2 and a remainder of 114.
Use 2 as the next digit of our solution. 
Result so far: 334677.5070422
Deduct 426 from 540 and we're left with 114.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

After the division, we end up with 334677.5070422 and a remainder of 1.14e-06.
