We divide 91144004 by 18
We want to figure out the number of times 91144004 can be divided by 18.

Step 1:
If we divide 9 by 18, we get 0 and a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Include the next digit (1) from the dividend after 9, then repeat: 91 / 18

Moving on to step 2:
The number 18 fits into 91 5 times, leaving a remainder of 1.
Write down 5 as next digit of the result. 
Result so far: 5.0
Subtract 90 from 91 to get 1.
Bring next digit (1) of the dividend behind the 1 and repeat the process: 11 / 18

Going ahead to step 3:
The number 18 fits into 11 0 times, leaving a remainder of 11.
Put 0 as the next digit of the answer. 
Result so far: 50.0
If we take 0 away from 11, we end up with 11.
Fetch the next digit (4) from the dividend, attach it to 11 and continue: 114 / 18

Moving on to step 4:
When dividing 114 by 18, we get 6 with a remainder of 6.
Write down 6 as next digit of the result. 
Result so far: 506.0
Subtract 108 from 114 to get 6.
Grab the next digit (4) from the dividend, add it to 6, then carry on: 64 / 18

Going ahead to step 5:
64 divided by 18 is 3 with a remainder of 10.
Put 3 as the next digit of the answer. 
Result so far: 5063.0
Deduct 54 from 64 and we're left with 10.
Take the next digit (0) from the dividend and append it to 10, then repeat: 100 / 18

Let's proceed to step 6:
100 divided by 18 is 5 with a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 50635.0
Deduct 90 from 100 and we're left with 10.
Include the next digit (0) from the dividend after 10, then repeat: 100 / 18

Let's proceed to step 7:
18 can be fit into 100 5 times, resulting in a remainder of 10.
The next digit of our result is 5. 
Result so far: 506355.0
The remainder is 10 after subtracting 90 from 100.
Bring next digit (4) of the dividend behind the 10 and repeat the process: 104 / 18

Going ahead to step 8:
18 can be fit into 104 5 times, resulting in a remainder of 14.
Put 5 as the next digit of the answer. 
Result so far: 5063555.0
Subtract 90 from 104 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 9:
18 goes into 140 7 times with a remainder of 14.
The number 7 becomes the next digit in our result. 
Result so far: 5063555.7
Subtract 126 from 140 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 10:
The number 18 fits into 140 7 times, leaving a remainder of 14.
The number 7 becomes the next digit in our result. 
Result so far: 5063555.77
The remainder is 14 after subtracting 126 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Our division results in 5063555.77 with a remaining 0.014.
