We divide 835981 by 20
Let's see how many times 20 fits into 835981.

Moving on to step 1:
The number 20 fits into 8 0 times, leaving a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Grab the next digit (3) from the dividend, add it to 8, then carry on: 83 / 20

On to step 2:
The number 20 fits into 83 4 times, leaving a remainder of 3.
Write down 4 as next digit of the result. 
Result so far: 4.0
If we take 80 away from 83, we end up with 3.
Bring next digit (5) of the dividend behind the 3 and repeat the process: 35 / 20

Going ahead to step 3:
If we divide 35 by 20, we get 1 and a remainder of 15.
Put 1 as the next digit of the answer. 
Result so far: 41.0
Subtracting 20 from 35 leaves us with 15.
Include the next digit (9) from the dividend after 15, then repeat: 159 / 20

Step 4:
If we divide 159 by 20, we get 7 and a remainder of 19.
Use 7 as the next digit of our solution. 
Result so far: 417.0
If we take 140 away from 159, we end up with 19.
Grab the next digit (8) from the dividend, add it to 19, then carry on: 198 / 20

On to step 5:
20 can be fit into 198 9 times, resulting in a remainder of 18.
Record the quotient 9 as the next digit in the result. 
Result so far: 4179.0
If we subtract 180 from 198, we get 18.
Grab the next digit (1) from the dividend, add it to 18, then carry on: 181 / 20

Step 6:
The number 20 fits into 181 9 times, leaving a remainder of 1.
Write down 9 as next digit of the result. 
Result so far: 41799.0
Deduct 180 from 181 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 7:
20 can be fit into 10 0 times, resulting in a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 41799.0
The remainder is 10 after subtracting 0 from 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 8:
100 divided by 20 is 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 41799.05
Subtract 100 from 100 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.

Going ahead to step 9:
The number 20 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 41799.05
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.

Advancing to step 10:
0 divided by 20 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 41799.05
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.

Our division results in 41799.05 with a remaining 0.0.
