70395696 ÷ 646 
We want to divide 70395696 by 646.

On to step 1:
646 goes into 7 0 times with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Grab the next digit (0) from the dividend, add it to 7, then carry on: 70 / 646

Going ahead to step 2:
646 can be fit into 70 0 times, resulting in a remainder of 70.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 70 after subtracting 0 from 70.
Append the next digit (3) from the dividend to 70 and continue with: 703 / 646

On to step 3:
646 goes into 703 1 times with a remainder of 57.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 646 from 703 and we're left with 57.
Append the next digit (9) from the dividend to 57 and continue with: 579 / 646

Let's proceed to step 4:
646 goes into 579 0 times with a remainder of 579.
Put 0 as the next digit of the answer. 
Result so far: 10.0
If we take 0 away from 579, we end up with 579.
Include the next digit (5) from the dividend after 579, then repeat: 5795 / 646

Moving on to step 5:
646 can be fit into 5795 8 times, resulting in a remainder of 627.
Use 8 as the next digit of our solution. 
Result so far: 108.0
If we subtract 5168 from 5795, we get 627.
Take the next digit (6) from the dividend and append it to 627, then repeat: 6276 / 646

Let's proceed to step 6:
If we divide 6276 by 646, we get 9 and a remainder of 462.
Use 9 as the next digit of our solution. 
Result so far: 1089.0
The remainder is 462 after subtracting 5814 from 6276.
Include the next digit (9) from the dividend after 462, then repeat: 4629 / 646

On to step 7:
646 can be fit into 4629 7 times, resulting in a remainder of 107.
Put 7 as the next digit of the answer. 
Result so far: 10897.0
Subtract 4522 from 4629 to get 107.
Include the next digit (6) from the dividend after 107, then repeat: 1076 / 646

Moving on to step 8:
646 can be fit into 1076 1 times, resulting in a remainder of 430.
Record the quotient 1 as the next digit in the result. 
Result so far: 108971.0
The remainder is 430 after subtracting 646 from 1076.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4300, and continue the process.

Advancing to step 9:
646 can be fit into 4300 6 times, resulting in a remainder of 424.
The next digit of our result is 6. 
Result so far: 108971.6
If we take 3876 away from 4300, we end up with 424.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4240, and continue the process.

Going ahead to step 10:
4240 divided by 646 is 6 with a remainder of 364.
Put 6 as the next digit of the answer. 
Result so far: 108971.66
Deduct 3876 from 4240 and we're left with 364.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3640, and continue the process.

Our division results in 108971.66 with a remaining 0.364.
