We look at the division of 18121882 by 406 
Our goal is to divide 18121882 by 406.

Going ahead to step 1:
1 divided by 406 is 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Take the next digit (8) from the dividend and append it to 1, then repeat: 18 / 406

Step 2:
If we divide 18 by 406, we get 0 and a remainder of 18.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 18, we end up with 18.
Bring next digit (1) of the dividend behind the 18 and repeat the process: 181 / 406

Advancing to step 3:
If we divide 181 by 406, we get 0 and a remainder of 181.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 181 to get 181.
Fetch the next digit (2) from the dividend, attach it to 181 and continue: 1812 / 406

Moving on to step 4:
406 goes into 1812 4 times with a remainder of 188.
The next digit of our result is 4. 
Result so far: 4.0
Subtract 1624 from 1812 to get 188.
Bring next digit (1) of the dividend behind the 188 and repeat the process: 1881 / 406

Advancing to step 5:
406 can be fit into 1881 4 times, resulting in a remainder of 257.
Record the quotient 4 as the next digit in the result. 
Result so far: 44.0
Deduct 1624 from 1881 and we're left with 257.
Include the next digit (8) from the dividend after 257, then repeat: 2578 / 406

Let's proceed to step 6:
When dividing 2578 by 406, we get 6 with a remainder of 142.
Use 6 as the next digit of our solution. 
Result so far: 446.0
If we subtract 2436 from 2578, we get 142.
Take the next digit (8) from the dividend and append it to 142, then repeat: 1428 / 406

On to step 7:
When dividing 1428 by 406, we get 3 with a remainder of 210.
Record the quotient 3 as the next digit in the result. 
Result so far: 4463.0
Deduct 1218 from 1428 and we're left with 210.
Take the next digit (2) from the dividend and append it to 210, then repeat: 2102 / 406

Going ahead to step 8:
406 goes into 2102 5 times with a remainder of 72.
Put 5 as the next digit of the answer. 
Result so far: 44635.0
The remainder is 72 after subtracting 2030 from 2102.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Let's proceed to step 9:
720 divided by 406 is 1 with a remainder of 314.
Record the quotient 1 as the next digit in the result. 
Result so far: 44635.1
The remainder is 314 after subtracting 406 from 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3140, and continue the process.

Let's proceed to step 10:
The number 406 fits into 3140 7 times, leaving a remainder of 298.
Use 7 as the next digit of our solution. 
Result so far: 44635.17
Subtracting 2842 from 3140 leaves us with 298.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2980, and continue the process.

On to step 11:
The number 406 fits into 2980 7 times, leaving a remainder of 138.
Put 7 as the next digit of the answer. 
Result so far: 44635.177
The remainder is 138 after subtracting 2842 from 2980.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1380, and continue the process.

The final result is 44635.177 with a remainder of 0.0138.
