We're dividing 869006 by 20 
We want to divide 869006 by 20.

Step 1:
When dividing 8 by 20, we get 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Grab the next digit (6) from the dividend, add it to 8, then carry on: 86 / 20

Advancing to step 2:
86 divided by 20 is 4 with a remainder of 6.
Write down 4 as next digit of the result. 
Result so far: 4.0
If we subtract 80 from 86, we get 6.
Bring next digit (9) of the dividend behind the 6 and repeat the process: 69 / 20

Going ahead to step 3:
The number 20 fits into 69 3 times, leaving a remainder of 9.
Write down 3 as next digit of the result. 
Result so far: 43.0
The remainder is 9 after subtracting 60 from 69.
Take the next digit (0) from the dividend and append it to 9, then repeat: 90 / 20

Advancing to step 4:
90 divided by 20 is 4 with a remainder of 10.
The number 4 becomes the next digit in our result. 
Result so far: 434.0
Deduct 80 from 90 and we're left with 10.
Grab the next digit (0) from the dividend, add it to 10, then carry on: 100 / 20

On to step 5:
If we divide 100 by 20, we get 5 and a remainder of 0.
The next digit of our result is 5. 
Result so far: 4345.0
Subtract 100 from 100 to get 0.
Take the next digit (6) from the dividend and append it to 0, then repeat: 6 / 20

Let's proceed to step 6:
The number 20 fits into 6 0 times, leaving a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 43450.0
If we take 0 away from 6, we end up 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 7:
If we divide 60 by 20, we get 3 and a remainder of 0.
Put 3 as the next digit of the answer. 
Result so far: 43450.3
If we subtract 60 from 60, 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 8:
0 divided by 20 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 43450.3
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.

Going ahead to step 9:
When dividing 0 by 20, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 43450.3
Subtract 0 from 0 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.

After the division, we end up with 43450.3 and a remainder of 0.0.
