We divide 53990 by 20
We want to divide 53990 by 20.

Let's proceed to step 1:
20 goes into 5 0 times with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Grab the next digit (3) from the dividend, add it to 5, then carry on: 53 / 20

Advancing to step 2:
The number 20 fits into 53 2 times, leaving a remainder of 13.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we take 40 away from 53, we end up with 13.
Fetch the next digit (9) from the dividend, attach it to 13 and continue: 139 / 20

Moving on to step 3:
The number 20 fits into 139 6 times, leaving a remainder of 19.
Record the quotient 6 as the next digit in the result. 
Result so far: 26.0
Deduct 120 from 139 and we're left with 19.
Grab the next digit (9) from the dividend, add it to 19, then carry on: 199 / 20

Advancing to step 4:
20 goes into 199 9 times with a remainder of 19.
Use 9 as the next digit of our solution. 
Result so far: 269.0
If we take 180 away from 199, we end up with 19.
Include the next digit (0) from the dividend after 19, then repeat: 190 / 20

On to step 5:
The number 20 fits into 190 9 times, leaving a remainder of 10.
The number 9 becomes the next digit in our result. 
Result so far: 2699.0
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.

Step 6:
When dividing 100 by 20, we get 5 with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 2699.5
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 7:
When dividing 0 by 20, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 2699.5
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.

On to step 8:
20 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 2699.5
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.

The final outcome is 2699.5, with a leftover of 0.0.
