70643280 ÷ 814 
We want to figure out the number of times 70643280 can be divided by 814.

Step 1:
7 divided by 814 is 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Append the next digit (0) from the dividend to 7 and continue with: 70 / 814

Step 2:
814 can be fit into 70 0 times, resulting in a remainder of 70.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 70 after subtracting 0 from 70.
Take the next digit (6) from the dividend and append it to 70, then repeat: 706 / 814

Let's proceed to step 3:
When dividing 706 by 814, we get 0 with a remainder of 706.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 706 and we're left with 706.
Fetch the next digit (4) from the dividend, attach it to 706 and continue: 7064 / 814

Step 4:
7064 divided by 814 is 8 with a remainder of 552.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
The remainder is 552 after subtracting 6512 from 7064.
Fetch the next digit (3) from the dividend, attach it to 552 and continue: 5523 / 814

On to step 5:
5523 divided by 814 is 6 with a remainder of 639.
Put 6 as the next digit of the answer. 
Result so far: 86.0
If we subtract 4884 from 5523, we get 639.
Bring next digit (2) of the dividend behind the 639 and repeat the process: 6392 / 814

Step 6:
814 can be fit into 6392 7 times, resulting in a remainder of 694.
The next digit of our result is 7. 
Result so far: 867.0
Subtracting 5698 from 6392 leaves us with 694.
Append the next digit (8) from the dividend to 694 and continue with: 6948 / 814

Step 7:
814 goes into 6948 8 times with a remainder of 436.
Put 8 as the next digit of the answer. 
Result so far: 8678.0
The remainder is 436 after subtracting 6512 from 6948.
Bring next digit (0) of the dividend behind the 436 and repeat the process: 4360 / 814

Going ahead to step 8:
If we divide 4360 by 814, we get 5 and a remainder of 290.
Write down 5 as next digit of the result. 
Result so far: 86785.0
If we take 4070 away from 4360, we end up with 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

Going ahead to step 9:
The number 814 fits into 2900 3 times, leaving a remainder of 458.
The number 3 becomes the next digit in our result. 
Result so far: 86785.3
If we subtract 2442 from 2900, we get 458.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4580, and continue the process.

Advancing to step 10:
4580 divided by 814 is 5 with a remainder of 510.
Put 5 as the next digit of the answer. 
Result so far: 86785.35
Subtracting 4070 from 4580 leaves us with 510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5100, and continue the process.

On to step 11:
5100 divided by 814 is 6 with a remainder of 216.
The next digit of our result is 6. 
Result so far: 86785.356
Subtracting 4884 from 5100 leaves us with 216.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

Advancing to step 12:
If we divide 2160 by 814, we get 2 and a remainder of 532.
The number 2 becomes the next digit in our result. 
Result so far: 86785.3562
Deduct 1628 from 2160 and we're left with 532.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5320, and continue the process.

On to step 13:
814 goes into 5320 6 times with a remainder of 436.
The number 6 becomes the next digit in our result. 
Result so far: 86785.35626
The remainder is 436 after subtracting 4884 from 5320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4360, and continue the process.

Let's proceed to step 14:
If we divide 4360 by 814, we get 5 and a remainder of 290.
Put 5 as the next digit of the answer. 
Result so far: 86785.356265
Subtracting 4070 from 4360 leaves us with 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

Moving on to step 15:
When dividing 2900 by 814, we get 3 with a remainder of 458.
The next digit of our result is 3. 
Result so far: 86785.3562653
Subtract 2442 from 2900 to get 458.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4580, and continue the process.

On to step 16:
If we divide 4580 by 814, we get 5 and a remainder of 510.
Use 5 as the next digit of our solution. 
Result so far: 86785.35626535
Subtracting 4070 from 4580 leaves us with 510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5100, and continue the process.

The quotient of the division is 86785.35626535, and the remainder is 5.1e-07.
