68483159 ÷ 20 
We want to divide 68483159 by 20.

Let's proceed to step 1:
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: 0.0
The remainder is 6 after subtracting 0 from 6.
Append the next digit (8) from the dividend to 6 and continue with: 68 / 20

Moving on to step 2:
When dividing 68 by 20, we get 3 with a remainder of 8.
Write down 3 as next digit of the result. 
Result so far: 3.0
The remainder is 8 after subtracting 60 from 68.
Append the next digit (4) from the dividend to 8 and continue with: 84 / 20

Moving on to step 3:
84 divided by 20 is 4 with a remainder of 4.
Write down 4 as next digit of the result. 
Result so far: 34.0
Subtract 80 from 84 to get 4.
Include the next digit (8) from the dividend after 4, then repeat: 48 / 20

Step 4:
When dividing 48 by 20, we get 2 with a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 342.0
Subtracting 40 from 48 leaves us with 8.
Fetch the next digit (3) from the dividend, attach it to 8 and continue: 83 / 20

On to step 5:
20 goes into 83 4 times with a remainder of 3.
Put 4 as the next digit of the answer. 
Result so far: 3424.0
Subtracting 80 from 83 leaves us with 3.
Grab the next digit (1) from the dividend, add it to 3, then carry on: 31 / 20

Let's proceed to step 6:
20 can be fit into 31 1 times, resulting in a remainder of 11.
Write down 1 as next digit of the result. 
Result so far: 34241.0
If we take 20 away from 31, we end up with 11.
Grab the next digit (5) from the dividend, add it to 11, then carry on: 115 / 20

Advancing to step 7:
20 can be fit into 115 5 times, resulting in a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 342415.0
The remainder is 15 after subtracting 100 from 115.
Bring next digit (9) of the dividend behind the 15 and repeat the process: 159 / 20

Advancing to step 8:
The number 20 fits into 159 7 times, leaving a remainder of 19.
Put 7 as the next digit of the answer. 
Result so far: 3424157.0
Subtracting 140 from 159 leaves us 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.

Advancing to step 9:
If we divide 190 by 20, we get 9 and a remainder of 10.
Record the quotient 9 as the next digit in the result. 
Result so far: 3424157.9
Subtract 180 from 190 to 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.

Step 10:
When dividing 100 by 20, we get 5 with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 3424157.95
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.

Advancing to step 11:
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: 3424157.95
The remainder is 0 after subtracting 0 from 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 12:
0 divided by 20 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 3424157.95
The remainder is 0 after subtracting 0 from 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 3424157.95, with a leftover of 0.0.
