70451765 ÷ 685 
Our goal is to divide 70451765 by 685.

Step 1:
If we divide 7 by 685, we get 0 and 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.
Append the next digit (0) from the dividend to 7 and continue with: 70 / 685

Advancing to step 2:
The number 685 fits into 70 0 times, leaving a remainder of 70.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 70 to get 70.
Include the next digit (4) from the dividend after 70, then repeat: 704 / 685

Going ahead to step 3:
685 goes into 704 1 times with a remainder of 19.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 685 from 704 to get 19.
Grab the next digit (5) from the dividend, add it to 19, then carry on: 195 / 685

On to step 4:
When dividing 195 by 685, we get 0 with a remainder of 195.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
Deduct 0 from 195 and we're left with 195.
Include the next digit (1) from the dividend after 195, then repeat: 1951 / 685

Advancing to step 5:
685 goes into 1951 2 times with a remainder of 581.
Use 2 as the next digit of our solution. 
Result so far: 102.0
If we take 1370 away from 1951, we end up with 581.
Grab the next digit (7) from the dividend, add it to 581, then carry on: 5817 / 685

Let's proceed to step 6:
5817 divided by 685 is 8 with a remainder of 337.
The next digit of our result is 8. 
Result so far: 1028.0
If we subtract 5480 from 5817, we get 337.
Append the next digit (6) from the dividend to 337 and continue with: 3376 / 685

Advancing to step 7:
If we divide 3376 by 685, we get 4 and a remainder of 636.
The next digit of our result is 4. 
Result so far: 10284.0
The remainder is 636 after subtracting 2740 from 3376.
Take the next digit (5) from the dividend and append it to 636, then repeat: 6365 / 685

Advancing to step 8:
If we divide 6365 by 685, we get 9 and a remainder of 200.
The next digit of our result is 9. 
Result so far: 102849.0
Deduct 6165 from 6365 and we're left with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Step 9:
685 goes into 2000 2 times with a remainder of 630.
The next digit of our result is 2. 
Result so far: 102849.2
Subtracting 1370 from 2000 leaves us with 630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6300, and continue the process.

On to step 10:
685 goes into 6300 9 times with a remainder of 135.
Record the quotient 9 as the next digit in the result. 
Result so far: 102849.29
If we subtract 6165 from 6300, we get 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

On to step 11:
1350 divided by 685 is 1 with a remainder of 665.
The number 1 becomes the next digit in our result. 
Result so far: 102849.291
Subtracting 685 from 1350 leaves us with 665.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6650, and continue the process.

Let's proceed to step 12:
6650 divided by 685 is 9 with a remainder of 485.
Write down 9 as next digit of the result. 
Result so far: 102849.2919
Subtract 6165 from 6650 to get 485.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4850, and continue the process.

Step 13:
The number 685 fits into 4850 7 times, leaving a remainder of 55.
The number 7 becomes the next digit in our result. 
Result so far: 102849.29197
Deduct 4795 from 4850 and we're left with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Step 14:
If we divide 550 by 685, we get 0 and a remainder of 550.
Write down 0 as next digit of the result. 
Result so far: 102849.29197
Subtracting 0 from 550 leaves us with 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5500, and continue the process.

Advancing to step 15:
If we divide 5500 by 685, we get 8 and a remainder of 20.
Put 8 as the next digit of the answer. 
Result so far: 102849.2919708
The remainder is 20 after subtracting 5480 from 5500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 16:
200 divided by 685 is 0 with a remainder of 200.
Put 0 as the next digit of the answer. 
Result so far: 102849.2919708
Subtract 0 from 200 to get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

After the division, we end up with 102849.2919708 and a remainder of 2e-07.
