89279544 ÷ 20 
We want to divide 89279544 by 20.

Advancing to step 1:
20 goes into 8 0 times with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Fetch the next digit (9) from the dividend, attach it to 8 and continue: 89 / 20

On to step 2:
89 divided by 20 is 4 with a remainder of 9.
Put 4 as the next digit of the answer. 
Result so far: 4.0
If we subtract 80 from 89, we get 9.
Grab the next digit (2) from the dividend, add it to 9, then carry on: 92 / 20

Advancing to step 3:
20 goes into 92 4 times with a remainder of 12.
Put 4 as the next digit of the answer. 
Result so far: 44.0
Subtract 80 from 92 to get 12.
Grab the next digit (7) from the dividend, add it to 12, then carry on: 127 / 20

Going ahead to step 4:
20 can be fit into 127 6 times, resulting in a remainder of 7.
Put 6 as the next digit of the answer. 
Result so far: 446.0
If we subtract 120 from 127, we get 7.
Grab the next digit (9) from the dividend, add it to 7, then carry on: 79 / 20

On to step 5:
20 goes into 79 3 times with a remainder of 19.
Use 3 as the next digit of our solution. 
Result so far: 4463.0
If we take 60 away from 79, we end up with 19.
Include the next digit (5) from the dividend after 19, then repeat: 195 / 20

Let's proceed to step 6:
When dividing 195 by 20, we get 9 with a remainder of 15.
Record the quotient 9 as the next digit in the result. 
Result so far: 44639.0
Subtracting 180 from 195 leaves us with 15.
Include the next digit (4) from the dividend after 15, then repeat: 154 / 20

Let's proceed to step 7:
If we divide 154 by 20, we get 7 and a remainder of 14.
Write down 7 as next digit of the result. 
Result so far: 446397.0
If we subtract 140 from 154, we get 14.
Include the next digit (4) from the dividend after 14, then repeat: 144 / 20

Step 8:
20 can be fit into 144 7 times, resulting in a remainder of 4.
Write down 7 as next digit of the result. 
Result so far: 4463977.0
If we subtract 140 from 144, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 9:
The number 20 fits into 40 2 times, leaving a remainder of 0.
The next digit of our result is 2. 
Result so far: 4463977.2
If we subtract 40 from 40, 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.

On to step 10:
20 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 4463977.2
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.

Moving on to step 11:
0 divided by 20 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 4463977.2
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.

In conclusion, the division gives 4463977.2 with a balance of 0.0.
