We look at the division of 81820572 by 4 
Our goal is to divide 81820572 by 4.

Moving on to step 1:
If we divide 8 by 4, we get 2 and a remainder of 0.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we take 8 away from 8, we end up with 0.
Grab the next digit (1) from the dividend, add it to 0, then carry on: 1 / 4

Going ahead to step 2:
4 goes into 1 0 times with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 20.0
If we take 0 away from 1, we end up with 1.
Grab the next digit (8) from the dividend, add it to 1, then carry on: 18 / 4

Advancing to step 3:
If we divide 18 by 4, we get 4 and a remainder of 2.
Put 4 as the next digit of the answer. 
Result so far: 204.0
The remainder is 2 after subtracting 16 from 18.
Bring next digit (2) of the dividend behind the 2 and repeat the process: 22 / 4

Advancing to step 4:
4 can be fit into 22 5 times, resulting in a remainder of 2.
The next digit of our result is 5. 
Result so far: 2045.0
If we take 20 away from 22, we end up with 2.
Grab the next digit (0) from the dividend, add it to 2, then carry on: 20 / 4

Advancing to step 5:
When dividing 20 by 4, we get 5 with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 20455.0
Deduct 20 from 20 and we're left with 0.
Fetch the next digit (5) from the dividend, attach it to 0 and continue: 5 / 4

Let's proceed to step 6:
5 divided by 4 is 1 with a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 204551.0
Deduct 4 from 5 and we're left with 1.
Fetch the next digit (7) from the dividend, attach it to 1 and continue: 17 / 4

Let's proceed to step 7:
4 can be fit into 17 4 times, resulting in a remainder of 1.
The number 4 becomes the next digit in our result. 
Result so far: 2045514.0
Deduct 16 from 17 and we're left with 1.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 4

Step 8:
12 divided by 4 is 3 with a remainder of 0.
The number 3 becomes the next digit in our result. 
Result so far: 20455143.0
If we subtract 12 from 12, 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 9:
0 divided by 4 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 20455143.0
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.

Step 10:
4 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 20455143.0
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 20455143.0, with a leftover of 0.0.
