426126 ÷ 20 
We want to figure out the number of times 426126 can be divided by 20.

Advancing to step 1:
When dividing 4 by 20, we get 0 with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Grab the next digit (2) from the dividend, add it to 4, then carry on: 42 / 20

Advancing to step 2:
42 divided by 20 is 2 with a remainder of 2.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we subtract 40 from 42, we get 2.
Fetch the next digit (6) from the dividend, attach it to 2 and continue: 26 / 20

Advancing to step 3:
20 can be fit into 26 1 times, resulting in a remainder of 6.
The next digit of our result is 1. 
Result so far: 21.0
If we subtract 20 from 26, we get 6.
Fetch the next digit (1) from the dividend, attach it to 6 and continue: 61 / 20

Advancing to step 4:
When dividing 61 by 20, we get 3 with a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 213.0
The remainder is 1 after subtracting 60 from 61.
Grab the next digit (2) from the dividend, add it to 1, then carry on: 12 / 20

On to step 5:
20 goes into 12 0 times with a remainder of 12.
Record the quotient 0 as the next digit in the result. 
Result so far: 2130.0
The remainder is 12 after subtracting 0 from 12.
Take the next digit (6) from the dividend and append it to 12, then repeat: 126 / 20

Moving on to step 6:
20 can be fit into 126 6 times, resulting in a remainder of 6.
Write down 6 as next digit of the result. 
Result so far: 21306.0
If we take 120 away from 126, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 7:
If we divide 60 by 20, we get 3 and a remainder of 0.
Write down 3 as next digit of the result. 
Result so far: 21306.3
Subtracting 60 from 60 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:
If we divide 0 by 20, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 21306.3
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.

Advancing to step 9:
When dividing 0 by 20, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 21306.3
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 quotient of the division is 21306.3, and the remainder is 0.0.
