We divide 21874 by 20
We're looking to find how many times 20 goes into 21874.

Advancing to step 1:
20 goes into 2 0 times with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 20

On to step 2:
If we divide 21 by 20, we get 1 and a remainder of 1.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 20 from 21, we get 1.
Grab the next digit (8) from the dividend, add it to 1, then carry on: 18 / 20

Moving on to step 3:
When dividing 18 by 20, we get 0 with a remainder of 18.
The next digit of our result is 0. 
Result so far: 10.0
Subtracting 0 from 18 leaves us with 18.
Include the next digit (7) from the dividend after 18, then repeat: 187 / 20

Step 4:
When dividing 187 by 20, we get 9 with a remainder of 7.
Write down 9 as next digit of the result. 
Result so far: 109.0
The remainder is 7 after subtracting 180 from 187.
Include the next digit (4) from the dividend after 7, then repeat: 74 / 20

Advancing to step 5:
When dividing 74 by 20, we get 3 with a remainder of 14.
Write down 3 as next digit of the result. 
Result so far: 1093.0
Subtracting 60 from 74 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 6:
When dividing 140 by 20, we get 7 with a remainder of 0.
Use 7 as the next digit of our solution. 
Result so far: 1093.7
Subtract 140 from 140 to 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.

Advancing to step 7:
20 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 1093.7
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.

Advancing to step 8:
0 divided by 20 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 1093.7
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 1093.7, with a leftover of 0.0.
