We look at the division of 48090532 by 4 
Let's see how many times 4 fits into 48090532.

Moving on to step 1:
4 goes into 4 1 times with a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 4 from 4 leaves us with 0.
Grab the next digit (8) from the dividend, add it to 0, then carry on: 8 / 4

Step 2:
4 can be fit into 8 2 times, resulting in a remainder of 0.
Put 2 as the next digit of the answer. 
Result so far: 12.0
If we take 8 away from 8, we end up with 0.
Take the next digit (0) from the dividend and append it to 0, then repeat: 0 / 4

Advancing to step 3:
0 divided by 4 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 120.0
Subtracting 0 from 0 leaves us with 0.
Bring next digit (9) of the dividend behind the 0 and repeat the process: 9 / 4

Moving on to step 4:
9 divided by 4 is 2 with a remainder of 1.
Write down 2 as next digit of the result. 
Result so far: 1202.0
Subtract 8 from 9 to get 1.
Fetch the next digit (0) from the dividend, attach it to 1 and continue: 10 / 4

Moving on to step 5:
4 goes into 10 2 times with a remainder of 2.
Write down 2 as next digit of the result. 
Result so far: 12022.0
Deduct 8 from 10 and we're left with 2.
Fetch the next digit (5) from the dividend, attach it to 2 and continue: 25 / 4

Advancing to step 6:
25 divided by 4 is 6 with a remainder of 1.
The number 6 becomes the next digit in our result. 
Result so far: 120226.0
If we subtract 24 from 25, we get 1.
Fetch the next digit (3) from the dividend, attach it to 1 and continue: 13 / 4

Advancing to step 7:
4 can be fit into 13 3 times, resulting in a remainder of 1.
Record the quotient 3 as the next digit in the result. 
Result so far: 1202263.0
If we subtract 12 from 13, we get 1.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 4

Moving on to step 8:
If we divide 12 by 4, we get 3 and a remainder of 0.
The number 3 becomes the next digit in our result. 
Result so far: 12022633.0
If we take 12 away from 12, 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.

Advancing to step 9:
4 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 12022633.0
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.

Advancing to step 10:
4 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 12022633.0
The remainder is 0 after subtracting 0 from 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 outcome is 12022633.0, with a leftover of 0.0.
