Let's divide 75122174 by 18
We're looking to find how many times 18 goes into 75122174.

On to step 1:
If we divide 7 by 18, we get 0 and a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Bring next digit (5) of the dividend behind the 7 and repeat the process: 75 / 18

Going ahead to step 2:
If we divide 75 by 18, we get 4 and a remainder of 3.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Subtracting 72 from 75 leaves us with 3.
Take the next digit (1) from the dividend and append it to 3, then repeat: 31 / 18

Let's proceed to step 3:
The number 18 fits into 31 1 times, leaving a remainder of 13.
Record the quotient 1 as the next digit in the result. 
Result so far: 41.0
Subtract 18 from 31 to get 13.
Include the next digit (2) from the dividend after 13, then repeat: 132 / 18

On to step 4:
When dividing 132 by 18, we get 7 with a remainder of 6.
Record the quotient 7 as the next digit in the result. 
Result so far: 417.0
If we subtract 126 from 132, we get 6.
Fetch the next digit (2) from the dividend, attach it to 6 and continue: 62 / 18

Advancing to step 5:
If we divide 62 by 18, we get 3 and a remainder of 8.
The number 3 becomes the next digit in our result. 
Result so far: 4173.0
Deduct 54 from 62 and we're left with 8.
Bring next digit (1) of the dividend behind the 8 and repeat the process: 81 / 18

Going ahead to step 6:
18 goes into 81 4 times with a remainder of 9.
Put 4 as the next digit of the answer. 
Result so far: 41734.0
If we subtract 72 from 81, we get 9.
Fetch the next digit (7) from the dividend, attach it to 9 and continue: 97 / 18

Step 7:
When dividing 97 by 18, we get 5 with a remainder of 7.
Use 5 as the next digit of our solution. 
Result so far: 417345.0
Subtracting 90 from 97 leaves us with 7.
Append the next digit (4) from the dividend to 7 and continue with: 74 / 18

On to step 8:
The number 18 fits into 74 4 times, leaving a remainder of 2.
Use 4 as the next digit of our solution. 
Result so far: 4173454.0
Subtract 72 from 74 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.

Let's proceed to step 9:
18 can be fit into 20 1 times, resulting in a remainder of 2.
The number 1 becomes the next digit in our result. 
Result so far: 4173454.1
If we take 18 away from 20, we end up 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 10:
If we divide 20 by 18, we get 1 and a remainder of 2.
Write down 1 as next digit of the result. 
Result so far: 4173454.11
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.

The final outcome is 4173454.11, with a leftover of 0.002.
