345907 ÷ 18 
We want to divide 345907 by 18.

Moving on to step 1:
If we divide 3 by 18, we get 0 and a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Grab the next digit (4) from the dividend, add it to 3, then carry on: 34 / 18

Going ahead to step 2:
34 divided by 18 is 1 with a remainder of 16.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 18 from 34 to get 16.
Take the next digit (5) from the dividend and append it to 16, then repeat: 165 / 18

Step 3:
165 divided by 18 is 9 with a remainder of 3.
Write down 9 as next digit of the result. 
Result so far: 19.0
The remainder is 3 after subtracting 162 from 165.
Take the next digit (9) from the dividend and append it to 3, then repeat: 39 / 18

Going ahead to step 4:
If we divide 39 by 18, we get 2 and a remainder of 3.
Record the quotient 2 as the next digit in the result. 
Result so far: 192.0
If we take 36 away from 39, we end up with 3.
Include the next digit (0) from the dividend after 3, then repeat: 30 / 18

Advancing to step 5:
The number 18 fits into 30 1 times, leaving a remainder of 12.
Use 1 as the next digit of our solution. 
Result so far: 1921.0
If we take 18 away from 30, we end up with 12.
Include the next digit (7) from the dividend after 12, then repeat: 127 / 18

Let's proceed to step 6:
127 divided by 18 is 7 with a remainder of 1.
Use 7 as the next digit of our solution. 
Result so far: 19217.0
Subtracting 126 from 127 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.

Advancing to step 7:
When dividing 10 by 18, we get 0 with a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 19217.0
Deduct 0 from 10 and we're left 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.

Advancing to step 8:
If we divide 100 by 18, we get 5 and a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 19217.05
Subtracting 90 from 100 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.

Step 9:
The number 18 fits into 100 5 times, leaving a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 19217.055
If we subtract 90 from 100, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

After the division, we end up with 19217.055 and a remainder of 0.001.
