We look at the division of 70011590 by 25 
We want to figure out the number of times 70011590 can be divided by 25.

Moving on to step 1:
25 can be fit into 7 0 times, resulting in a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Bring next digit (0) of the dividend behind the 7 and repeat the process: 70 / 25

On to step 2:
If we divide 70 by 25, we get 2 and a remainder of 20.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtract 50 from 70 to get 20.
Grab the next digit (0) from the dividend, add it to 20, then carry on: 200 / 25

Going ahead to step 3:
If we divide 200 by 25, we get 8 and a remainder of 0.
Write down 8 as next digit of the result. 
Result so far: 28.0
If we subtract 200 from 200, we get 0.
Take the next digit (1) from the dividend and append it to 0, then repeat: 1 / 25

Step 4:
25 goes into 1 0 times with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 280.0
Subtract 0 from 1 to get 1.
Bring next digit (1) of the dividend behind the 1 and repeat the process: 11 / 25

Advancing to step 5:
25 goes into 11 0 times with a remainder of 11.
Record the quotient 0 as the next digit in the result. 
Result so far: 2800.0
Deduct 0 from 11 and we're left with 11.
Append the next digit (5) from the dividend to 11 and continue with: 115 / 25

Going ahead to step 6:
The number 25 fits into 115 4 times, leaving a remainder of 15.
Use 4 as the next digit of our solution. 
Result so far: 28004.0
Subtract 100 from 115 to get 15.
Grab the next digit (9) from the dividend, add it to 15, then carry on: 159 / 25

Let's proceed to step 7:
The number 25 fits into 159 6 times, leaving a remainder of 9.
Put 6 as the next digit of the answer. 
Result so far: 280046.0
Subtracting 150 from 159 leaves us with 9.
Append the next digit (0) from the dividend to 9 and continue with: 90 / 25

Step 8:
90 divided by 25 is 3 with a remainder of 15.
The next digit of our result is 3. 
Result so far: 2800463.0
The remainder is 15 after subtracting 75 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 9:
25 goes into 150 6 times with a remainder of 0.
Record the quotient 6 as the next digit in the result. 
Result so far: 2800463.6
Subtract 150 from 150 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 10:
If we divide 0 by 25, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 2800463.6
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 11:
When dividing 0 by 25, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 2800463.6
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 2800463.6 with a remaining 0.0.
