We divide 81084548 by 4
Our goal is to divide 81084548 by 4.

On to step 1:
If we divide 8 by 4, we get 2 and a remainder of 0.
Write down 2 as next digit of the result. 
Result so far: 2.0
Deduct 8 from 8 and we're left with 0.
Append the next digit (1) from the dividend to 0 and continue with: 1 / 4

On to step 2:
4 goes into 1 0 times with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 20.0
If we take 0 away from 1, we end up with 1.
Append the next digit (0) from the dividend to 1 and continue with: 10 / 4

Going ahead to step 3:
If we divide 10 by 4, we get 2 and a remainder of 2.
Write down 2 as next digit of the result. 
Result so far: 202.0
If we subtract 8 from 10, we get 2.
Bring next digit (8) of the dividend behind the 2 and repeat the process: 28 / 4

Going ahead to step 4:
28 divided by 4 is 7 with a remainder of 0.
Put 7 as the next digit of the answer. 
Result so far: 2027.0
If we subtract 28 from 28, we get 0.
Grab the next digit (4) from the dividend, add it to 0, then carry on: 4 / 4

Moving on to step 5:
4 goes into 4 1 times with a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 20271.0
The remainder is 0 after subtracting 4 from 4.
Bring next digit (5) of the dividend behind the 0 and repeat the process: 5 / 4

Let's proceed to step 6:
5 divided by 4 is 1 with a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 202711.0
Deduct 4 from 5 and we're left with 1.
Take the next digit (4) from the dividend and append it to 1, then repeat: 14 / 4

Let's proceed to step 7:
The number 4 fits into 14 3 times, leaving a remainder of 2.
Put 3 as the next digit of the answer. 
Result so far: 2027113.0
Subtract 12 from 14 to get 2.
Take the next digit (8) from the dividend and append it to 2, then repeat: 28 / 4

On to step 8:
The number 4 fits into 28 7 times, leaving a remainder of 0.
The next digit of our result is 7. 
Result so far: 20271137.0
The remainder is 0 after subtracting 28 from 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 9:
0 divided by 4 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 20271137.0
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.

Going ahead to step 10:
0 divided by 4 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 20271137.0
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 outcome is 20271137.0, with a leftover of 0.0.
