261629 ÷ 20 
Let's see how many times 20 fits into 261629.

Let's proceed to step 1:
20 can be fit into 2 0 times, resulting in a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Take the next digit (6) from the dividend and append it to 2, then repeat: 26 / 20

Moving on to step 2:
The number 20 fits into 26 1 times, leaving a remainder of 6.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 20 from 26, we get 6.
Take the next digit (1) from the dividend and append it to 6, then repeat: 61 / 20

Moving on to step 3:
The number 20 fits into 61 3 times, leaving a remainder of 1.
Put 3 as the next digit of the answer. 
Result so far: 13.0
The remainder is 1 after subtracting 60 from 61.
Take the next digit (6) from the dividend and append it to 1, then repeat: 16 / 20

Advancing to step 4:
When dividing 16 by 20, we get 0 with a remainder of 16.
Write down 0 as next digit of the result. 
Result so far: 130.0
If we subtract 0 from 16, we get 16.
Include the next digit (2) from the dividend after 16, then repeat: 162 / 20

Let's proceed to step 5:
20 can be fit into 162 8 times, resulting in a remainder of 2.
The next digit of our result is 8. 
Result so far: 1308.0
Subtracting 160 from 162 leaves us with 2.
Grab the next digit (9) from the dividend, add it to 2, then carry on: 29 / 20

On to step 6:
20 goes into 29 1 times with a remainder of 9.
Put 1 as the next digit of the answer. 
Result so far: 13081.0
If we subtract 20 from 29, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Moving on to step 7:
If we divide 90 by 20, we get 4 and a remainder of 10.
Record the quotient 4 as the next digit in the result. 
Result so far: 13081.4
Subtract 80 from 90 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.

Moving on to step 8:
The number 20 fits into 100 5 times, leaving a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 13081.45
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.

Going ahead to step 9:
20 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 13081.45
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.

Moving on to step 10:
If we divide 0 by 20, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 13081.45
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 13081.45, with a leftover of 0.0.
