30840890 ÷ 710 
We want to divide 30840890 by 710.

Step 1:
The number 710 fits into 3 0 times, leaving a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Grab the next digit (0) from the dividend, add it to 3, then carry on: 30 / 710

Step 2:
When dividing 30 by 710, we get 0 with a remainder of 30.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 30 and we're left with 30.
Append the next digit (8) from the dividend to 30 and continue with: 308 / 710

Advancing to step 3:
When dividing 308 by 710, we get 0 with a remainder of 308.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 308 and we're left with 308.
Take the next digit (4) from the dividend and append it to 308, then repeat: 3084 / 710

Step 4:
If we divide 3084 by 710, we get 4 and a remainder of 244.
The next digit of our result is 4. 
Result so far: 4.0
Subtract 2840 from 3084 to get 244.
Fetch the next digit (0) from the dividend, attach it to 244 and continue: 2440 / 710

Advancing to step 5:
If we divide 2440 by 710, we get 3 and a remainder of 310.
Put 3 as the next digit of the answer. 
Result so far: 43.0
If we subtract 2130 from 2440, we get 310.
Fetch the next digit (8) from the dividend, attach it to 310 and continue: 3108 / 710

Step 6:
If we divide 3108 by 710, we get 4 and a remainder of 268.
The next digit of our result is 4. 
Result so far: 434.0
If we subtract 2840 from 3108, we get 268.
Take the next digit (9) from the dividend and append it to 268, then repeat: 2689 / 710

Step 7:
2689 divided by 710 is 3 with a remainder of 559.
Record the quotient 3 as the next digit in the result. 
Result so far: 4343.0
If we subtract 2130 from 2689, we get 559.
Bring next digit (0) of the dividend behind the 559 and repeat the process: 5590 / 710

Moving on to step 8:
When dividing 5590 by 710, we get 7 with a remainder of 620.
Write down 7 as next digit of the result. 
Result so far: 43437.0
The remainder is 620 after subtracting 4970 from 5590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6200, and continue the process.

On to step 9:
If we divide 6200 by 710, we get 8 and a remainder of 520.
Write down 8 as next digit of the result. 
Result so far: 43437.8
The remainder is 520 after subtracting 5680 from 6200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

Moving on to step 10:
710 can be fit into 5200 7 times, resulting in a remainder of 230.
The next digit of our result is 7. 
Result so far: 43437.87
Deduct 4970 from 5200 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.

Step 11:
710 can be fit into 2300 3 times, resulting in a remainder of 170.
Use 3 as the next digit of our solution. 
Result so far: 43437.873
Subtract 2130 from 2300 to get 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Let's proceed to step 12:
When dividing 1700 by 710, we get 2 with a remainder of 280.
Use 2 as the next digit of our solution. 
Result so far: 43437.8732
Deduct 1420 from 1700 and we're left with 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Step 13:
710 goes into 2800 3 times with a remainder of 670.
The number 3 becomes the next digit in our result. 
Result so far: 43437.87323
Subtract 2130 from 2800 to get 670.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6700, and continue the process.

Let's proceed to step 14:
If we divide 6700 by 710, we get 9 and a remainder of 310.
The next digit of our result is 9. 
Result so far: 43437.873239
If we subtract 6390 from 6700, we get 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

Moving on to step 15:
3100 divided by 710 is 4 with a remainder of 260.
Use 4 as the next digit of our solution. 
Result so far: 43437.8732394
Subtract 2840 from 3100 to get 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Step 16:
The number 710 fits into 2600 3 times, leaving a remainder of 470.
Put 3 as the next digit of the answer. 
Result so far: 43437.87323943
Subtract 2130 from 2600 to get 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4700, and continue the process.

The final result is 43437.87323943 with a remainder of 4.7e-07.
