189109 divided by 5 
Let's see how many times 5 fits into 189109.

On to step 1:
1 divided by 5 is 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Take the next digit (8) from the dividend and append it to 1, then repeat: 18 / 5

Moving on to step 2:
If we divide 18 by 5, we get 3 and a remainder of 3.
The next digit of our result is 3. 
Result so far: 3.0
Deduct 15 from 18 and we're left with 3.
Take the next digit (9) from the dividend and append it to 3, then repeat: 39 / 5

Step 3:
5 can be fit into 39 7 times, resulting in a remainder of 4.
Use 7 as the next digit of our solution. 
Result so far: 37.0
Deduct 35 from 39 and we're left with 4.
Grab the next digit (1) from the dividend, add it to 4, then carry on: 41 / 5

Moving on to step 4:
If we divide 41 by 5, we get 8 and a remainder of 1.
Use 8 as the next digit of our solution. 
Result so far: 378.0
Deduct 40 from 41 and we're left with 1.
Append the next digit (0) from the dividend to 1 and continue with: 10 / 5

On to step 5:
5 can be fit into 10 2 times, resulting in a remainder of 0.
The next digit of our result is 2. 
Result so far: 3782.0
Subtracting 10 from 10 leaves us with 0.
Append the next digit (9) from the dividend to 0 and continue with: 9 / 5

Let's proceed to step 6:
9 divided by 5 is 1 with a remainder of 4.
Write down 1 as next digit of the result. 
Result so far: 37821.0
If we take 5 away from 9, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 7:
5 goes into 40 8 times with a remainder of 0.
Put 8 as the next digit of the answer. 
Result so far: 37821.8
The remainder is 0 after subtracting 40 from 40.
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:
When dividing 0 by 5, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 37821.8
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.

Step 9:
When dividing 0 by 5, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 37821.8
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 37821.8, with a leftover of 0.0.
