We divide 41860 by 21
We want to divide 41860 by 21.

Step 1:
The number 21 fits into 4 0 times, leaving a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Take the next digit (1) from the dividend and append it to 4, then repeat: 41 / 21

Advancing to step 2:
41 divided by 21 is 1 with a remainder of 20.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 20 after subtracting 21 from 41.
Take the next digit (8) from the dividend and append it to 20, then repeat: 208 / 21

Advancing to step 3:
21 can be fit into 208 9 times, resulting in a remainder of 19.
Write down 9 as next digit of the result. 
Result so far: 19.0
The remainder is 19 after subtracting 189 from 208.
Include the next digit (6) from the dividend after 19, then repeat: 196 / 21

Step 4:
If we divide 196 by 21, we get 9 and a remainder of 7.
Record the quotient 9 as the next digit in the result. 
Result so far: 199.0
The remainder is 7 after subtracting 189 from 196.
Grab the next digit (0) from the dividend, add it to 7, then carry on: 70 / 21

Moving on to step 5:
21 goes into 70 3 times with a remainder of 7.
Use 3 as the next digit of our solution. 
Result so far: 1993.0
Subtracting 63 from 70 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 6:
If we divide 70 by 21, we get 3 and a remainder of 7.
Write down 3 as next digit of the result. 
Result so far: 1993.3
Deduct 63 from 70 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 7:
21 goes into 70 3 times with a remainder of 7.
Write down 3 as next digit of the result. 
Result so far: 1993.33
If we take 63 away from 70, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

In conclusion, the division gives 1993.33 with a balance of 0.007.
