112689 ÷ 30 
Our goal is to divide 112689 by 30.

Going ahead to step 1:
The number 30 fits into 1 0 times, leaving a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Append the next digit (1) from the dividend to 1 and continue with: 11 / 30

Going ahead to step 2:
30 goes into 11 0 times with a remainder of 11.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 11 after subtracting 0 from 11.
Grab the next digit (2) from the dividend, add it to 11, then carry on: 112 / 30

Step 3:
If we divide 112 by 30, we get 3 and a remainder of 22.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Deduct 90 from 112 and we're left with 22.
Take the next digit (6) from the dividend and append it to 22, then repeat: 226 / 30

Advancing to step 4:
If we divide 226 by 30, we get 7 and a remainder of 16.
Write down 7 as next digit of the result. 
Result so far: 37.0
If we take 210 away from 226, we end up with 16.
Fetch the next digit (8) from the dividend, attach it to 16 and continue: 168 / 30

Moving on to step 5:
30 goes into 168 5 times with a remainder of 18.
Write down 5 as next digit of the result. 
Result so far: 375.0
If we subtract 150 from 168, we get 18.
Append the next digit (9) from the dividend to 18 and continue with: 189 / 30

Advancing to step 6:
30 goes into 189 6 times with a remainder of 9.
The next digit of our result is 6. 
Result so far: 3756.0
Subtracting 180 from 189 leaves us with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Going ahead to step 7:
When dividing 90 by 30, we get 3 with a remainder of 0.
Record the quotient 3 as the next digit in the result. 
Result so far: 3756.3
If we subtract 90 from 90, 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.

Going ahead to step 8:
If we divide 0 by 30, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 3756.3
Subtracting 0 from 0 leaves us 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.

Let's proceed to step 9:
The number 30 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 3756.3
Subtracting 0 from 0 leaves us 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.

The final outcome is 3756.3, with a leftover of 0.0.
