70485514 ÷ 257 
We're looking to find how many times 257 goes into 70485514.

Going ahead to step 1:
7 divided by 257 is 0 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.
Bring next digit (0) of the dividend behind the 7 and repeat the process: 70 / 257

Let's proceed to step 2:
The number 257 fits into 70 0 times, leaving a remainder of 70.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 70 and we're left with 70.
Take the next digit (4) from the dividend and append it to 70, then repeat: 704 / 257

On to step 3:
257 goes into 704 2 times with a remainder of 190.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Deduct 514 from 704 and we're left with 190.
Include the next digit (8) from the dividend after 190, then repeat: 1908 / 257

Advancing to step 4:
When dividing 1908 by 257, we get 7 with a remainder of 109.
Write down 7 as next digit of the result. 
Result so far: 27.0
Subtracting 1799 from 1908 leaves us with 109.
Take the next digit (5) from the dividend and append it to 109, then repeat: 1095 / 257

Advancing to step 5:
257 can be fit into 1095 4 times, resulting in a remainder of 67.
Write down 4 as next digit of the result. 
Result so far: 274.0
Deduct 1028 from 1095 and we're left with 67.
Bring next digit (5) of the dividend behind the 67 and repeat the process: 675 / 257

On to step 6:
The number 257 fits into 675 2 times, leaving a remainder of 161.
Put 2 as the next digit of the answer. 
Result so far: 2742.0
Subtracting 514 from 675 leaves us with 161.
Bring next digit (1) of the dividend behind the 161 and repeat the process: 1611 / 257

Going ahead to step 7:
If we divide 1611 by 257, we get 6 and a remainder of 69.
The number 6 becomes the next digit in our result. 
Result so far: 27426.0
The remainder is 69 after subtracting 1542 from 1611.
Grab the next digit (4) from the dividend, add it to 69, then carry on: 694 / 257

On to step 8:
If we divide 694 by 257, we get 2 and a remainder of 180.
The next digit of our result is 2. 
Result so far: 274262.0
The remainder is 180 after subtracting 514 from 694.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Let's proceed to step 9:
When dividing 1800 by 257, we get 7 with a remainder of 1.
Use 7 as the next digit of our solution. 
Result so far: 274262.7
If we take 1799 away from 1800, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 10:
257 goes into 10 0 times with a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 274262.7
Subtract 0 from 10 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 11:
When dividing 100 by 257, we get 0 with a remainder of 100.
The next digit of our result is 0. 
Result so far: 274262.7
Subtracting 0 from 100 leaves us with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Our division results in 274262.7 with a remaining 0.01.
