We're dividing 30310017 by 715 
Let's see how many times 715 fits into 30310017.

On to step 1:
The number 715 fits into 3 0 times, leaving a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Bring next digit (0) of the dividend behind the 3 and repeat the process: 30 / 715

On to step 2:
The number 715 fits into 30 0 times, leaving a remainder of 30.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 30 to get 30.
Take the next digit (3) from the dividend and append it to 30, then repeat: 303 / 715

Going ahead to step 3:
When dividing 303 by 715, we get 0 with a remainder of 303.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 303 leaves us with 303.
Grab the next digit (1) from the dividend, add it to 303, then carry on: 3031 / 715

Step 4:
715 goes into 3031 4 times with a remainder of 171.
Write down 4 as next digit of the result. 
Result so far: 4.0
If we subtract 2860 from 3031, we get 171.
Bring next digit (0) of the dividend behind the 171 and repeat the process: 1710 / 715

On to step 5:
If we divide 1710 by 715, we get 2 and a remainder of 280.
Use 2 as the next digit of our solution. 
Result so far: 42.0
If we take 1430 away from 1710, we end up with 280.
Take the next digit (0) from the dividend and append it to 280, then repeat: 2800 / 715

Moving on to step 6:
2800 divided by 715 is 3 with a remainder of 655.
The next digit of our result is 3. 
Result so far: 423.0
If we take 2145 away from 2800, we end up with 655.
Bring next digit (1) of the dividend behind the 655 and repeat the process: 6551 / 715

Let's proceed to step 7:
When dividing 6551 by 715, we get 9 with a remainder of 116.
Use 9 as the next digit of our solution. 
Result so far: 4239.0
If we subtract 6435 from 6551, we get 116.
Fetch the next digit (7) from the dividend, attach it to 116 and continue: 1167 / 715

Moving on to step 8:
When dividing 1167 by 715, we get 1 with a remainder of 452.
Use 1 as the next digit of our solution. 
Result so far: 42391.0
Deduct 715 from 1167 and we're left with 452.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4520, and continue the process.

Step 9:
715 goes into 4520 6 times with a remainder of 230.
Put 6 as the next digit of the answer. 
Result so far: 42391.6
Deduct 4290 from 4520 and we're left with 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Moving on to step 10:
The number 715 fits into 2300 3 times, leaving a remainder of 155.
Record the quotient 3 as the next digit in the result. 
Result so far: 42391.63
Subtracting 2145 from 2300 leaves us with 155.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1550, and continue the process.

Moving on to step 11:
If we divide 1550 by 715, we get 2 and a remainder of 120.
Put 2 as the next digit of the answer. 
Result so far: 42391.632
If we subtract 1430 from 1550, we get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Advancing to step 12:
715 goes into 1200 1 times with a remainder of 485.
Record the quotient 1 as the next digit in the result. 
Result so far: 42391.6321
Deduct 715 from 1200 and we're left with 485.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4850, and continue the process.

Advancing to step 13:
4850 divided by 715 is 6 with a remainder of 560.
Write down 6 as next digit of the result. 
Result so far: 42391.63216
Deduct 4290 from 4850 and we're left with 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

Step 14:
5600 divided by 715 is 7 with a remainder of 595.
Put 7 as the next digit of the answer. 
Result so far: 42391.632167
Subtracting 5005 from 5600 leaves us with 595.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5950, and continue the process.

Let's proceed to step 15:
When dividing 5950 by 715, we get 8 with a remainder of 230.
Put 8 as the next digit of the answer. 
Result so far: 42391.6321678
If we take 5720 away from 5950, we end up with 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Step 16:
When dividing 2300 by 715, we get 3 with a remainder of 155.
The next digit of our result is 3. 
Result so far: 42391.63216783
Subtract 2145 from 2300 to get 155.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1550, and continue the process.

The final outcome is 42391.63216783, with a leftover of 1.55e-07.
