Let's divide 71280870 by 4
We want to divide 71280870 by 4.

Going ahead to step 1:
The number 4 fits into 7 1 times, leaving a remainder of 3.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 3 after subtracting 4 from 7.
Grab the next digit (1) from the dividend, add it to 3, then carry on: 31 / 4

Step 2:
The number 4 fits into 31 7 times, leaving a remainder of 3.
Write down 7 as next digit of the result. 
Result so far: 17.0
Subtract 28 from 31 to get 3.
Include the next digit (2) from the dividend after 3, then repeat: 32 / 4

On to step 3:
4 goes into 32 8 times with a remainder of 0.
The number 8 becomes the next digit in our result. 
Result so far: 178.0
Subtract 32 from 32 to get 0.
Bring next digit (8) of the dividend behind the 0 and repeat the process: 8 / 4

Moving on to step 4:
If we divide 8 by 4, we get 2 and a remainder of 0.
Put 2 as the next digit of the answer. 
Result so far: 1782.0
Subtracting 8 from 8 leaves us with 0.
Fetch the next digit (0) from the dividend, attach it to 0 and continue: 0 / 4

Going ahead to step 5:
The number 4 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 17820.0
If we take 0 away from 0, we end up with 0.
Take the next digit (8) from the dividend and append it to 0, then repeat: 8 / 4

Advancing to step 6:
The number 4 fits into 8 2 times, leaving a remainder of 0.
The next digit of our result is 2. 
Result so far: 178202.0
Subtract 8 from 8 to get 0.
Append the next digit (7) from the dividend to 0 and continue with: 7 / 4

Moving on to step 7:
If we divide 7 by 4, we get 1 and a remainder of 3.
Put 1 as the next digit of the answer. 
Result so far: 1782021.0
If we take 4 away from 7, we end up with 3.
Take the next digit (0) from the dividend and append it to 3, then repeat: 30 / 4

Let's proceed to step 8:
The number 4 fits into 30 7 times, leaving a remainder of 2.
The number 7 becomes the next digit in our result. 
Result so far: 17820217.0
If we subtract 28 from 30, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 9:
If we divide 20 by 4, we get 5 and a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 17820217.5
If we subtract 20 from 20, we 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.

On to step 10:
When dividing 0 by 4, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 17820217.5
If we take 0 away from 0, we end up 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.

On to step 11:
The number 4 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 17820217.5
If we take 0 away from 0, we end up 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.

In conclusion, the division gives 17820217.5 with a balance of 0.0.
