We're dividing 12290 by 667 
We want to divide 12290 by 667.

On to step 1:
When dividing 1 by 667, we get 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 667

Step 2:
The number 667 fits into 12 0 times, leaving a remainder of 12.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 12, we get 12.
Take the next digit (2) from the dividend and append it to 12, then repeat: 122 / 667

Moving on to step 3:
When dividing 122 by 667, we get 0 with a remainder of 122.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 122, we get 122.
Grab the next digit (9) from the dividend, add it to 122, then carry on: 1229 / 667

On to step 4:
1229 divided by 667 is 1 with a remainder of 562.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 667 from 1229 and we're left with 562.
Take the next digit (0) from the dividend and append it to 562, then repeat: 5620 / 667

Let's proceed to step 5:
5620 divided by 667 is 8 with a remainder of 284.
Put 8 as the next digit of the answer. 
Result so far: 18.0
If we subtract 5336 from 5620, we get 284.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2840, and continue the process.

Let's proceed to step 6:
When dividing 2840 by 667, we get 4 with a remainder of 172.
Record the quotient 4 as the next digit in the result. 
Result so far: 18.4
Deduct 2668 from 2840 and we're left with 172.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

Moving on to step 7:
When dividing 1720 by 667, we get 2 with a remainder of 386.
Use 2 as the next digit of our solution. 
Result so far: 18.42
Subtracting 1334 from 1720 leaves us with 386.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3860, and continue the process.

Going ahead to step 8:
The number 667 fits into 3860 5 times, leaving a remainder of 525.
The number 5 becomes the next digit in our result. 
Result so far: 18.425
Subtracting 3335 from 3860 leaves us with 525.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5250, and continue the process.

Going ahead to step 9:
When dividing 5250 by 667, we get 7 with a remainder of 581.
Use 7 as the next digit of our solution. 
Result so far: 18.4257
If we subtract 4669 from 5250, we get 581.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5810, and continue the process.

Going ahead to step 10:
5810 divided by 667 is 8 with a remainder of 474.
Use 8 as the next digit of our solution. 
Result so far: 18.42578
The remainder is 474 after subtracting 5336 from 5810.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4740, and continue the process.

Let's proceed to step 11:
When dividing 4740 by 667, we get 7 with a remainder of 71.
Use 7 as the next digit of our solution. 
Result so far: 18.425787
If we subtract 4669 from 4740, we get 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Step 12:
710 divided by 667 is 1 with a remainder of 43.
The number 1 becomes the next digit in our result. 
Result so far: 18.4257871
Subtract 667 from 710 to get 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Let's proceed to step 13:
If we divide 430 by 667, we get 0 and a remainder of 430.
Record the quotient 0 as the next digit in the result. 
Result so far: 18.4257871
If we subtract 0 from 430, we get 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4300, and continue the process.

In conclusion, the division gives 18.4257871 with a balance of 4.3e-07.
