We divide 33921 by 31
We want to figure out the number of times 33921 can be divided by 31.

Moving on to step 1:
31 can be fit into 3 0 times, resulting in a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Fetch the next digit (3) from the dividend, attach it to 3 and continue: 33 / 31

Let's proceed to step 2:
31 goes into 33 1 times with a remainder of 2.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 31 from 33 leaves us with 2.
Grab the next digit (9) from the dividend, add it to 2, then carry on: 29 / 31

Advancing to step 3:
If we divide 29 by 31, we get 0 and a remainder of 29.
Put 0 as the next digit of the answer. 
Result so far: 10.0
If we take 0 away from 29, we end up with 29.
Grab the next digit (2) from the dividend, add it to 29, then carry on: 292 / 31

Moving on to step 4:
292 divided by 31 is 9 with a remainder of 13.
Put 9 as the next digit of the answer. 
Result so far: 109.0
Deduct 279 from 292 and we're left with 13.
Grab the next digit (1) from the dividend, add it to 13, then carry on: 131 / 31

Moving on to step 5:
The number 31 fits into 131 4 times, leaving a remainder of 7.
The next digit of our result is 4. 
Result so far: 1094.0
Deduct 124 from 131 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 6:
The number 31 fits into 70 2 times, leaving a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 1094.2
The remainder is 8 after subtracting 62 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 7:
If we divide 80 by 31, we get 2 and a remainder of 18.
Write down 2 as next digit of the result. 
Result so far: 1094.22
Deduct 62 from 80 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

After the division, we end up with 1094.22 and a remainder of 0.018.
