86363713 divided by 20 
Let's see how many times 20 fits into 86363713.

Let's proceed to step 1:
When dividing 8 by 20, we get 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Fetch the next digit (6) from the dividend, attach it to 8 and continue: 86 / 20

On to step 2:
If we divide 86 by 20, we get 4 and a remainder of 6.
Write down 4 as next digit of the result. 
Result so far: 4.0
If we take 80 away from 86, we end up with 6.
Append the next digit (3) from the dividend to 6 and continue with: 63 / 20

Moving on to step 3:
If we divide 63 by 20, we get 3 and a remainder of 3.
Use 3 as the next digit of our solution. 
Result so far: 43.0
Subtracting 60 from 63 leaves us with 3.
Append the next digit (6) from the dividend to 3 and continue with: 36 / 20

Step 4:
The number 20 fits into 36 1 times, leaving a remainder of 16.
The next digit of our result is 1. 
Result so far: 431.0
The remainder is 16 after subtracting 20 from 36.
Append the next digit (3) from the dividend to 16 and continue with: 163 / 20

Advancing to step 5:
20 goes into 163 8 times with a remainder of 3.
Use 8 as the next digit of our solution. 
Result so far: 4318.0
The remainder is 3 after subtracting 160 from 163.
Take the next digit (7) from the dividend and append it to 3, then repeat: 37 / 20

Step 6:
If we divide 37 by 20, we get 1 and a remainder of 17.
Use 1 as the next digit of our solution. 
Result so far: 43181.0
The remainder is 17 after subtracting 20 from 37.
Append the next digit (1) from the dividend to 17 and continue with: 171 / 20

Step 7:
20 goes into 171 8 times with a remainder of 11.
The next digit of our result is 8. 
Result so far: 431818.0
The remainder is 11 after subtracting 160 from 171.
Fetch the next digit (3) from the dividend, attach it to 11 and continue: 113 / 20

Advancing to step 8:
113 divided by 20 is 5 with a remainder of 13.
Put 5 as the next digit of the answer. 
Result so far: 4318185.0
If we subtract 100 from 113, we get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Advancing to step 9:
When dividing 130 by 20, we get 6 with a remainder of 10.
The number 6 becomes the next digit in our result. 
Result so far: 4318185.6
If we subtract 120 from 130, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 10:
The number 20 fits into 100 5 times, leaving a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 4318185.65
Subtracting 100 from 100 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.

Let's proceed to step 11:
20 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 4318185.65
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.

On to step 12:
The number 20 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 4318185.65
Subtracting 0 from 0 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.

The quotient of the division is 4318185.65, and the remainder is 0.0.
