We divide 31300891 by 111
We want to figure out the number of times 31300891 can be divided by 111.

Moving on to step 1:
When dividing 3 by 111, we get 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Include the next digit (1) from the dividend after 3, then repeat: 31 / 111

On to step 2:
31 divided by 111 is 0 with a remainder of 31.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 31 and we're left with 31.
Grab the next digit (3) from the dividend, add it to 31, then carry on: 313 / 111

Let's proceed to step 3:
The number 111 fits into 313 2 times, leaving a remainder of 91.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we subtract 222 from 313, we get 91.
Grab the next digit (0) from the dividend, add it to 91, then carry on: 910 / 111

Moving on to step 4:
The number 111 fits into 910 8 times, leaving a remainder of 22.
The next digit of our result is 8. 
Result so far: 28.0
Deduct 888 from 910 and we're left with 22.
Fetch the next digit (0) from the dividend, attach it to 22 and continue: 220 / 111

Going ahead to step 5:
When dividing 220 by 111, we get 1 with a remainder of 109.
Use 1 as the next digit of our solution. 
Result so far: 281.0
The remainder is 109 after subtracting 111 from 220.
Bring next digit (8) of the dividend behind the 109 and repeat the process: 1098 / 111

Going ahead to step 6:
111 can be fit into 1098 9 times, resulting in a remainder of 99.
Record the quotient 9 as the next digit in the result. 
Result so far: 2819.0
If we take 999 away from 1098, we end up with 99.
Include the next digit (9) from the dividend after 99, then repeat: 999 / 111

Step 7:
If we divide 999 by 111, we get 9 and a remainder of 0.
The number 9 becomes the next digit in our result. 
Result so far: 28199.0
Subtracting 999 from 999 leaves us with 0.
Include the next digit (1) from the dividend after 0, then repeat: 1 / 111

Moving on to step 8:
When dividing 1 by 111, we get 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 281990.0
Subtracting 0 from 1 leaves us 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.

Moving on to step 9:
111 goes into 10 0 times with a remainder of 10.
The next digit of our result is 0. 
Result so far: 281990.0
Subtracting 0 from 10 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 10:
111 goes into 100 0 times with a remainder of 100.
Put 0 as the next digit of the answer. 
Result so far: 281990.0
Deduct 0 from 100 and we're left with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

The final result is 281990.0 with a remainder of 0.1.
