68045790 ÷ 18 
We're looking to find how many times 18 goes into 68045790.

Moving on to step 1:
18 can be fit into 6 0 times, resulting in a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Include the next digit (8) from the dividend after 6, then repeat: 68 / 18

Going ahead to step 2:
When dividing 68 by 18, we get 3 with a remainder of 14.
Write down 3 as next digit of the result. 
Result so far: 3.0
Deduct 54 from 68 and we're left with 14.
Include the next digit (0) from the dividend after 14, then repeat: 140 / 18

On to step 3:
18 goes into 140 7 times with a remainder of 14.
The number 7 becomes the next digit in our result. 
Result so far: 37.0
If we take 126 away from 140, we end up with 14.
Fetch the next digit (4) from the dividend, attach it to 14 and continue: 144 / 18

Step 4:
If we divide 144 by 18, we get 8 and a remainder of 0.
Write down 8 as next digit of the result. 
Result so far: 378.0
Deduct 144 from 144 and we're left with 0.
Include the next digit (5) from the dividend after 0, then repeat: 5 / 18

On to step 5:
The number 18 fits into 5 0 times, leaving a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 3780.0
Subtracting 0 from 5 leaves us with 5.
Include the next digit (7) from the dividend after 5, then repeat: 57 / 18

Advancing to step 6:
57 divided by 18 is 3 with a remainder of 3.
The next digit of our result is 3. 
Result so far: 37803.0
Deduct 54 from 57 and we're left with 3.
Include the next digit (9) from the dividend after 3, then repeat: 39 / 18

Going ahead to step 7:
The number 18 fits into 39 2 times, leaving a remainder of 3.
The number 2 becomes the next digit in our result. 
Result so far: 378032.0
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 8:
The number 18 fits into 30 1 times, leaving a remainder of 12.
Write down 1 as next digit of the result. 
Result so far: 3780321.0
Subtracting 18 from 30 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 9:
18 can be fit into 120 6 times, resulting in a remainder of 12.
The number 6 becomes the next digit in our result. 
Result so far: 3780321.6
Deduct 108 from 120 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 10:
The number 18 fits into 120 6 times, leaving a remainder of 12.
Write down 6 as next digit of the result. 
Result so far: 3780321.66
If we take 108 away from 120, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Our division results in 3780321.66 with a remaining 0.012.
