We're dividing 762879 by 20 
We want to figure out the number of times 762879 can be divided by 20.

Moving on to step 1:
If we divide 7 by 20, we get 0 and a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Fetch the next digit (6) from the dividend, attach it to 7 and continue: 76 / 20

Step 2:
20 can be fit into 76 3 times, resulting in a remainder of 16.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we take 60 away from 76, we end up with 16.
Append the next digit (2) from the dividend to 16 and continue with: 162 / 20

Step 3:
The number 20 fits into 162 8 times, leaving a remainder of 2.
Write down 8 as next digit of the result. 
Result so far: 38.0
If we take 160 away from 162, we end up with 2.
Include the next digit (8) from the dividend after 2, then repeat: 28 / 20

Step 4:
If we divide 28 by 20, we get 1 and a remainder of 8.
Use 1 as the next digit of our solution. 
Result so far: 381.0
Deduct 20 from 28 and we're left with 8.
Include the next digit (7) from the dividend after 8, then repeat: 87 / 20

Advancing to step 5:
The number 20 fits into 87 4 times, leaving a remainder of 7.
The next digit of our result is 4. 
Result so far: 3814.0
Subtract 80 from 87 to get 7.
Grab the next digit (9) from the dividend, add it to 7, then carry on: 79 / 20

On to step 6:
20 can be fit into 79 3 times, resulting in a remainder of 19.
The next digit of our result is 3. 
Result so far: 38143.0
If we take 60 away from 79, we end up with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Let's proceed to step 7:
When dividing 190 by 20, we get 9 with a remainder of 10.
Put 9 as the next digit of the answer. 
Result so far: 38143.9
Subtracting 180 from 190 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.

Let's proceed to step 8:
20 goes into 100 5 times with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 38143.95
Deduct 100 from 100 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.

Going ahead to step 9:
The number 20 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 38143.95
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.

Going ahead to step 10:
The number 20 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 38143.95
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.

The final outcome is 38143.95, with a leftover of 0.0.
