We're dividing 70087443 by 259 
We want to figure out the number of times 70087443 can be divided by 259.

On to step 1:
7 divided by 259 is 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Grab the next digit (0) from the dividend, add it to 7, then carry on: 70 / 259

On to step 2:
70 divided by 259 is 0 with a remainder of 70.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 70, we end up with 70.
Take the next digit (0) from the dividend and append it to 70, then repeat: 700 / 259

Step 3:
The number 259 fits into 700 2 times, leaving a remainder of 182.
The next digit of our result is 2. 
Result so far: 2.0
The remainder is 182 after subtracting 518 from 700.
Append the next digit (8) from the dividend to 182 and continue with: 1828 / 259

Going ahead to step 4:
When dividing 1828 by 259, we get 7 with a remainder of 15.
Record the quotient 7 as the next digit in the result. 
Result so far: 27.0
Subtract 1813 from 1828 to get 15.
Bring next digit (7) of the dividend behind the 15 and repeat the process: 157 / 259

Moving on to step 5:
When dividing 157 by 259, we get 0 with a remainder of 157.
Write down 0 as next digit of the result. 
Result so far: 270.0
The remainder is 157 after subtracting 0 from 157.
Take the next digit (4) from the dividend and append it to 157, then repeat: 1574 / 259

Let's proceed to step 6:
The number 259 fits into 1574 6 times, leaving a remainder of 20.
Record the quotient 6 as the next digit in the result. 
Result so far: 2706.0
If we take 1554 away from 1574, we end up with 20.
Include the next digit (4) from the dividend after 20, then repeat: 204 / 259

Step 7:
259 can be fit into 204 0 times, resulting in a remainder of 204.
Use 0 as the next digit of our solution. 
Result so far: 27060.0
If we take 0 away from 204, we end up with 204.
Append the next digit (3) from the dividend to 204 and continue with: 2043 / 259

Advancing to step 8:
When dividing 2043 by 259, we get 7 with a remainder of 230.
The next digit of our result is 7. 
Result so far: 270607.0
The remainder is 230 after subtracting 1813 from 2043.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Advancing to step 9:
The number 259 fits into 2300 8 times, leaving a remainder of 228.
Use 8 as the next digit of our solution. 
Result so far: 270607.8
If we take 2072 away from 2300, we end up with 228.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2280, and continue the process.

Step 10:
If we divide 2280 by 259, we get 8 and a remainder of 208.
Put 8 as the next digit of the answer. 
Result so far: 270607.88
Subtracting 2072 from 2280 leaves us with 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

The final result is 270607.88 with a remainder of 0.208.
