We look at the division of 70015824 by 257 
We want to figure out the number of times 70015824 can be divided by 257.

Advancing to step 1:
257 goes into 7 0 times with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Take the next digit (0) from the dividend and append it to 7, then repeat: 70 / 257

Let's proceed to step 2:
70 divided by 257 is 0 with a remainder of 70.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 70, we get 70.
Include the next digit (0) from the dividend after 70, then repeat: 700 / 257

Advancing to step 3:
If we divide 700 by 257, we get 2 and a remainder of 186.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we take 514 away from 700, we end up with 186.
Take the next digit (1) from the dividend and append it to 186, then repeat: 1861 / 257

Step 4:
257 goes into 1861 7 times with a remainder of 62.
Record the quotient 7 as the next digit in the result. 
Result so far: 27.0
Deduct 1799 from 1861 and we're left with 62.
Include the next digit (5) from the dividend after 62, then repeat: 625 / 257

On to step 5:
If we divide 625 by 257, we get 2 and a remainder of 111.
Put 2 as the next digit of the answer. 
Result so far: 272.0
Subtract 514 from 625 to get 111.
Grab the next digit (8) from the dividend, add it to 111, then carry on: 1118 / 257

On to step 6:
The number 257 fits into 1118 4 times, leaving a remainder of 90.
Use 4 as the next digit of our solution. 
Result so far: 2724.0
Subtract 1028 from 1118 to get 90.
Fetch the next digit (2) from the dividend, attach it to 90 and continue: 902 / 257

Advancing to step 7:
The number 257 fits into 902 3 times, leaving a remainder of 131.
Write down 3 as next digit of the result. 
Result so far: 27243.0
The remainder is 131 after subtracting 771 from 902.
Bring next digit (4) of the dividend behind the 131 and repeat the process: 1314 / 257

On to step 8:
257 can be fit into 1314 5 times, resulting in a remainder of 29.
The number 5 becomes the next digit in our result. 
Result so far: 272435.0
If we take 1285 away from 1314, we end up with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Let's proceed to step 9:
If we divide 290 by 257, we get 1 and a remainder of 33.
The next digit of our result is 1. 
Result so far: 272435.1
Subtract 257 from 290 to get 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Let's proceed to step 10:
257 can be fit into 330 1 times, resulting in a remainder of 73.
The number 1 becomes the next digit in our result. 
Result so far: 272435.11
If we subtract 257 from 330, we get 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Our division results in 272435.11 with a remaining 0.073.
