We're dividing 58789786 by 20 
We want to divide 58789786 by 20.

On to step 1:
When dividing 5 by 20, we get 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Append the next digit (8) from the dividend to 5 and continue with: 58 / 20

Step 2:
When dividing 58 by 20, we get 2 with a remainder of 18.
Write down 2 as next digit of the result. 
Result so far: 2.0
The remainder is 18 after subtracting 40 from 58.
Bring next digit (7) of the dividend behind the 18 and repeat the process: 187 / 20

Step 3:
20 can be fit into 187 9 times, resulting in a remainder of 7.
The next digit of our result is 9. 
Result so far: 29.0
Deduct 180 from 187 and we're left with 7.
Fetch the next digit (8) from the dividend, attach it to 7 and continue: 78 / 20

Going ahead to step 4:
If we divide 78 by 20, we get 3 and a remainder of 18.
The next digit of our result is 3. 
Result so far: 293.0
If we take 60 away from 78, we end up with 18.
Take the next digit (9) from the dividend and append it to 18, then repeat: 189 / 20

On to step 5:
If we divide 189 by 20, we get 9 and a remainder of 9.
Put 9 as the next digit of the answer. 
Result so far: 2939.0
If we take 180 away from 189, we end up with 9.
Include the next digit (7) from the dividend after 9, then repeat: 97 / 20

Let's proceed to step 6:
When dividing 97 by 20, we get 4 with a remainder of 17.
The number 4 becomes the next digit in our result. 
Result so far: 29394.0
Deduct 80 from 97 and we're left with 17.
Include the next digit (8) from the dividend after 17, then repeat: 178 / 20

Step 7:
If we divide 178 by 20, we get 8 and a remainder of 18.
Use 8 as the next digit of our solution. 
Result so far: 293948.0
Deduct 160 from 178 and we're left with 18.
Include the next digit (6) from the dividend after 18, then repeat: 186 / 20

Advancing to step 8:
When dividing 186 by 20, we get 9 with a remainder of 6.
Put 9 as the next digit of the answer. 
Result so far: 2939489.0
Subtracting 180 from 186 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 9:
When dividing 60 by 20, we get 3 with a remainder of 0.
Put 3 as the next digit of the answer. 
Result so far: 2939489.3
Subtracting 60 from 60 leaves us 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:
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: 2939489.3
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.

On to step 11:
When dividing 0 by 20, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 2939489.3
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.

In conclusion, the division gives 2939489.3 with a balance of 0.0.
