18348945 divided by 1 
We're looking to find how many times 1 goes into 18348945.

Advancing to step 1:
1 can be fit into 1 1 times, resulting in a remainder of 0.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 1 from 1, we get 0.
Fetch the next digit (8) from the dividend, attach it to 0 and continue: 8 / 1

Going ahead to step 2:
1 goes into 8 8 times with a remainder of 0.
The number 8 becomes the next digit in our result. 
Result so far: 18.0
Deduct 8 from 8 and we're left with 0.
Include the next digit (3) from the dividend after 0, then repeat: 3 / 1

Let's proceed to step 3:
If we divide 3 by 1, we get 3 and a remainder of 0.
The number 3 becomes the next digit in our result. 
Result so far: 183.0
Deduct 3 from 3 and we're left with 0.
Include the next digit (4) from the dividend after 0, then repeat: 4 / 1

On to step 4:
1 goes into 4 4 times with a remainder of 0.
Record the quotient 4 as the next digit in the result. 
Result so far: 1834.0
The remainder is 0 after subtracting 4 from 4.
Bring next digit (8) of the dividend behind the 0 and repeat the process: 8 / 1

Step 5:
1 can be fit into 8 8 times, resulting in a remainder of 0.
The next digit of our result is 8. 
Result so far: 18348.0
Deduct 8 from 8 and we're left with 0.
Grab the next digit (9) from the dividend, add it to 0, then carry on: 9 / 1

On to step 6:
The number 1 fits into 9 9 times, leaving a remainder of 0.
Record the quotient 9 as the next digit in the result. 
Result so far: 183489.0
Deduct 9 from 9 and we're left with 0.
Append the next digit (4) from the dividend to 0 and continue with: 4 / 1

Step 7:
1 can be fit into 4 4 times, resulting in a remainder of 0.
Put 4 as the next digit of the answer. 
Result so far: 1834894.0
If we subtract 4 from 4, we get 0.
Include the next digit (5) from the dividend after 0, then repeat: 5 / 1

Step 8:
1 can be fit into 5 5 times, resulting in a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 18348945.0
Subtract 5 from 5 to 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.

Let's proceed to step 9:
If we divide 0 by 1, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 18348945.0
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.

Advancing to step 10:
1 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 18348945.0
The remainder is 0 after subtracting 0 from 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 18348945.0, with a leftover of 0.0.
