18217370 ÷ 126 
Let's see how many times 126 fits into 18217370.

Going ahead to step 1:
126 goes into 1 0 times with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Include the next digit (8) from the dividend after 1, then repeat: 18 / 126

Moving on to step 2:
18 divided by 126 is 0 with a remainder of 18.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 18, we get 18.
Include the next digit (2) from the dividend after 18, then repeat: 182 / 126

Step 3:
The number 126 fits into 182 1 times, leaving a remainder of 56.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 126 from 182 leaves us with 56.
Grab the next digit (1) from the dividend, add it to 56, then carry on: 561 / 126

Let's proceed to step 4:
The number 126 fits into 561 4 times, leaving a remainder of 57.
Write down 4 as next digit of the result. 
Result so far: 14.0
The remainder is 57 after subtracting 504 from 561.
Fetch the next digit (7) from the dividend, attach it to 57 and continue: 577 / 126

Advancing to step 5:
126 goes into 577 4 times with a remainder of 73.
Put 4 as the next digit of the answer. 
Result so far: 144.0
The remainder is 73 after subtracting 504 from 577.
Take the next digit (3) from the dividend and append it to 73, then repeat: 733 / 126

Going ahead to step 6:
126 can be fit into 733 5 times, resulting in a remainder of 103.
Write down 5 as next digit of the result. 
Result so far: 1445.0
If we subtract 630 from 733, we get 103.
Grab the next digit (7) from the dividend, add it to 103, then carry on: 1037 / 126

Let's proceed to step 7:
The number 126 fits into 1037 8 times, leaving a remainder of 29.
Write down 8 as next digit of the result. 
Result so far: 14458.0
Subtract 1008 from 1037 to get 29.
Append the next digit (0) from the dividend to 29 and continue with: 290 / 126

Step 8:
When dividing 290 by 126, we get 2 with a remainder of 38.
The number 2 becomes the next digit in our result. 
Result so far: 144582.0
If we subtract 252 from 290, we get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Step 9:
If we divide 380 by 126, we get 3 and a remainder of 2.
Use 3 as the next digit of our solution. 
Result so far: 144582.3
Deduct 378 from 380 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.

On to step 10:
126 goes into 20 0 times with a remainder of 20.
The next digit of our result is 0. 
Result so far: 144582.3
Subtracting 0 from 20 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 11:
The number 126 fits into 200 1 times, leaving a remainder of 74.
Write down 1 as next digit of the result. 
Result so far: 144582.301
Subtract 126 from 200 to get 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Step 12:
The number 126 fits into 740 5 times, leaving a remainder of 110.
Use 5 as the next digit of our solution. 
Result so far: 144582.3015
Subtract 630 from 740 to get 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

On to step 13:
126 goes into 1100 8 times with a remainder of 92.
Put 8 as the next digit of the answer. 
Result so far: 144582.30158
Subtracting 1008 from 1100 leaves us with 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Going ahead to step 14:
If we divide 920 by 126, we get 7 and a remainder of 38.
Put 7 as the next digit of the answer. 
Result so far: 144582.301587
The remainder is 38 after subtracting 882 from 920.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Let's proceed to step 15:
If we divide 380 by 126, we get 3 and a remainder of 2.
Write down 3 as next digit of the result. 
Result so far: 144582.3015873
If we subtract 378 from 380, we 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.

Going ahead to step 16:
126 can be fit into 20 0 times, resulting in a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 144582.3015873
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

In conclusion, the division gives 144582.3015873 with a balance of 2e-08.
