We're dividing 72498148 by 4 
Let's see how many times 4 fits into 72498148.

Let's proceed to step 1:
4 goes into 7 1 times with a remainder of 3.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 4 from 7 to get 3.
Include the next digit (2) from the dividend after 3, then repeat: 32 / 4

On to step 2:
If we divide 32 by 4, we get 8 and a remainder of 0.
The next digit of our result is 8. 
Result so far: 18.0
The remainder is 0 after subtracting 32 from 32.
Bring next digit (4) of the dividend behind the 0 and repeat the process: 4 / 4

On to step 3:
The number 4 fits into 4 1 times, leaving a remainder of 0.
The number 1 becomes the next digit in our result. 
Result so far: 181.0
If we subtract 4 from 4, we get 0.
Fetch the next digit (9) from the dividend, attach it to 0 and continue: 9 / 4

Moving on to step 4:
4 can be fit into 9 2 times, resulting in a remainder of 1.
The next digit of our result is 2. 
Result so far: 1812.0
If we subtract 8 from 9, we get 1.
Take the next digit (8) from the dividend and append it to 1, then repeat: 18 / 4

On to step 5:
4 goes into 18 4 times with a remainder of 2.
Write down 4 as next digit of the result. 
Result so far: 18124.0
Subtracting 16 from 18 leaves us with 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 4

Going ahead to step 6:
When dividing 21 by 4, we get 5 with a remainder of 1.
Record the quotient 5 as the next digit in the result. 
Result so far: 181245.0
If we take 20 away from 21, we end up with 1.
Grab the next digit (4) from the dividend, add it to 1, then carry on: 14 / 4

Going ahead to step 7:
When dividing 14 by 4, we get 3 with a remainder of 2.
The number 3 becomes the next digit in our result. 
Result so far: 1812453.0
The remainder is 2 after subtracting 12 from 14.
Append the next digit (8) from the dividend to 2 and continue with: 28 / 4

Advancing to step 8:
4 goes into 28 7 times with a remainder of 0.
Put 7 as the next digit of the answer. 
Result so far: 18124537.0
If we take 28 away from 28, 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.

Going ahead to step 9:
0 divided by 4 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 18124537.0
If we subtract 0 from 0, 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.

Going ahead to step 10:
If we divide 0 by 4, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 18124537.0
If we subtract 0 from 0, 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.

The final result is 18124537.0 with a remainder of 0.0.
