We look at the division of 85553093 by 18 
We want to figure out the number of times 85553093 can be divided by 18.

Going ahead to step 1:
If we divide 8 by 18, we get 0 and a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Bring next digit (5) of the dividend behind the 8 and repeat the process: 85 / 18

Step 2:
18 goes into 85 4 times with a remainder of 13.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Subtracting 72 from 85 leaves us with 13.
Fetch the next digit (5) from the dividend, attach it to 13 and continue: 135 / 18

Step 3:
If we divide 135 by 18, we get 7 and a remainder of 9.
Put 7 as the next digit of the answer. 
Result so far: 47.0
Subtracting 126 from 135 leaves us with 9.
Fetch the next digit (5) from the dividend, attach it to 9 and continue: 95 / 18

Step 4:
If we divide 95 by 18, we get 5 and a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 475.0
Subtracting 90 from 95 leaves us with 5.
Grab the next digit (3) from the dividend, add it to 5, then carry on: 53 / 18

Let's proceed to step 5:
18 goes into 53 2 times with a remainder of 17.
The number 2 becomes the next digit in our result. 
Result so far: 4752.0
Deduct 36 from 53 and we're left with 17.
Bring next digit (0) of the dividend behind the 17 and repeat the process: 170 / 18

Going ahead to step 6:
If we divide 170 by 18, we get 9 and a remainder of 8.
Put 9 as the next digit of the answer. 
Result so far: 47529.0
If we take 162 away from 170, we end up with 8.
Take the next digit (9) from the dividend and append it to 8, then repeat: 89 / 18

Step 7:
If we divide 89 by 18, we get 4 and a remainder of 17.
Put 4 as the next digit of the answer. 
Result so far: 475294.0
If we take 72 away from 89, we end up with 17.
Include the next digit (3) from the dividend after 17, then repeat: 173 / 18

Advancing to step 8:
The number 18 fits into 173 9 times, leaving a remainder of 11.
Use 9 as the next digit of our solution. 
Result so far: 4752949.0
The remainder is 11 after subtracting 162 from 173.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Going ahead to step 9:
18 can be fit into 110 6 times, resulting in a remainder of 2.
Use 6 as the next digit of our solution. 
Result so far: 4752949.6
Subtract 108 from 110 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 10:
18 goes into 20 1 times with a remainder of 2.
The next digit of our result is 1. 
Result so far: 4752949.61
Deduct 18 from 20 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 11:
The number 18 fits into 20 1 times, leaving a remainder of 2.
The number 1 becomes the next digit in our result. 
Result so far: 4752949.611
Subtract 18 from 20 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

The final outcome is 4752949.611, with a leftover of 0.0002.
