We divide 873693 by 20
We want to figure out the number of times 873693 can be divided by 20.

On to step 1:
The number 20 fits into 8 0 times, leaving a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Grab the next digit (7) from the dividend, add it to 8, then carry on: 87 / 20

Let's proceed to step 2:
20 goes into 87 4 times with a remainder of 7.
The next digit of our result is 4. 
Result so far: 4.0
Deduct 80 from 87 and we're left with 7.
Include the next digit (3) from the dividend after 7, then repeat: 73 / 20

Advancing to step 3:
The number 20 fits into 73 3 times, leaving a remainder of 13.
Write down 3 as next digit of the result. 
Result so far: 43.0
If we subtract 60 from 73, we get 13.
Fetch the next digit (6) from the dividend, attach it to 13 and continue: 136 / 20

On to step 4:
The number 20 fits into 136 6 times, leaving a remainder of 16.
Use 6 as the next digit of our solution. 
Result so far: 436.0
Subtracting 120 from 136 leaves us with 16.
Fetch the next digit (9) from the dividend, attach it to 16 and continue: 169 / 20

Let's proceed to step 5:
When dividing 169 by 20, we get 8 with a remainder of 9.
Write down 8 as next digit of the result. 
Result so far: 4368.0
If we take 160 away from 169, we end up with 9.
Fetch the next digit (3) from the dividend, attach it to 9 and continue: 93 / 20

On to step 6:
If we divide 93 by 20, we get 4 and a remainder of 13.
Use 4 as the next digit of our solution. 
Result so far: 43684.0
Deduct 80 from 93 and we're left with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Let's proceed to step 7:
20 can be fit into 130 6 times, resulting in a remainder of 10.
Record the quotient 6 as the next digit in the result. 
Result so far: 43684.6
Subtracting 120 from 130 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 8:
100 divided by 20 is 5 with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 43684.65
If we take 100 away from 100, 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.

Step 9:
When dividing 0 by 20, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 43684.65
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.

Step 10:
0 divided by 20 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 43684.65
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.

Our division results in 43684.65 with a remaining 0.0.
