We're dividing 86445772 by 20 
Let's see how many times 20 fits into 86445772.

Step 1:
20 goes into 8 0 times with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Fetch the next digit (6) from the dividend, attach it to 8 and continue: 86 / 20

Moving on to step 2:
86 divided by 20 is 4 with a remainder of 6.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Subtract 80 from 86 to get 6.
Bring next digit (4) of the dividend behind the 6 and repeat the process: 64 / 20

Let's proceed to step 3:
The number 20 fits into 64 3 times, leaving a remainder of 4.
Write down 3 as next digit of the result. 
Result so far: 43.0
Deduct 60 from 64 and we're left with 4.
Take the next digit (4) from the dividend and append it to 4, then repeat: 44 / 20

Going ahead to step 4:
20 goes into 44 2 times with a remainder of 4.
Use 2 as the next digit of our solution. 
Result so far: 432.0
If we take 40 away from 44, we end up with 4.
Include the next digit (5) from the dividend after 4, then repeat: 45 / 20

Advancing to step 5:
20 can be fit into 45 2 times, resulting in a remainder of 5.
Use 2 as the next digit of our solution. 
Result so far: 4322.0
If we take 40 away from 45, we end up with 5.
Append the next digit (7) from the dividend to 5 and continue with: 57 / 20

Step 6:
If we divide 57 by 20, we get 2 and a remainder of 17.
The number 2 becomes the next digit in our result. 
Result so far: 43222.0
If we take 40 away from 57, we end up with 17.
Fetch the next digit (7) from the dividend, attach it to 17 and continue: 177 / 20

Step 7:
If we divide 177 by 20, we get 8 and a remainder of 17.
Put 8 as the next digit of the answer. 
Result so far: 432228.0
Deduct 160 from 177 and we're left with 17.
Take the next digit (2) from the dividend and append it to 17, then repeat: 172 / 20

Advancing to step 8:
20 can be fit into 172 8 times, resulting in a remainder of 12.
The number 8 becomes the next digit in our result. 
Result so far: 4322288.0
The remainder is 12 after subtracting 160 from 172.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 9:
If we divide 120 by 20, we get 6 and a remainder of 0.
Record the quotient 6 as the next digit in the result. 
Result so far: 4322288.6
Subtract 120 from 120 to 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.

Moving on to step 10:
20 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 4322288.6
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.

Moving on to step 11:
The number 20 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 4322288.6
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.

In conclusion, the division gives 4322288.6 with a balance of 0.0.
