We're dividing 12489750 by 922 
Our goal is to divide 12489750 by 922.

Moving on to step 1:
If we divide 1 by 922, we get 0 and a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 922

Step 2:
If we divide 12 by 922, we get 0 and a remainder of 12.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 12, we end up with 12.
Fetch the next digit (4) from the dividend, attach it to 12 and continue: 124 / 922

Advancing to step 3:
922 can be fit into 124 0 times, resulting in a remainder of 124.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 124, we get 124.
Fetch the next digit (8) from the dividend, attach it to 124 and continue: 1248 / 922

Step 4:
If we divide 1248 by 922, we get 1 and a remainder of 326.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 922 from 1248 to get 326.
Include the next digit (9) from the dividend after 326, then repeat: 3269 / 922

On to step 5:
When dividing 3269 by 922, we get 3 with a remainder of 503.
The next digit of our result is 3. 
Result so far: 13.0
The remainder is 503 after subtracting 2766 from 3269.
Bring next digit (7) of the dividend behind the 503 and repeat the process: 5037 / 922

Moving on to step 6:
The number 922 fits into 5037 5 times, leaving a remainder of 427.
The next digit of our result is 5. 
Result so far: 135.0
If we subtract 4610 from 5037, we get 427.
Bring next digit (5) of the dividend behind the 427 and repeat the process: 4275 / 922

Moving on to step 7:
922 goes into 4275 4 times with a remainder of 587.
Write down 4 as next digit of the result. 
Result so far: 1354.0
Subtracting 3688 from 4275 leaves us with 587.
Fetch the next digit (0) from the dividend, attach it to 587 and continue: 5870 / 922

Step 8:
If we divide 5870 by 922, we get 6 and a remainder of 338.
Write down 6 as next digit of the result. 
Result so far: 13546.0
The remainder is 338 after subtracting 5532 from 5870.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3380, and continue the process.

Let's proceed to step 9:
922 goes into 3380 3 times with a remainder of 614.
Write down 3 as next digit of the result. 
Result so far: 13546.3
If we subtract 2766 from 3380, we get 614.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6140, and continue the process.

Going ahead to step 10:
When dividing 6140 by 922, we get 6 with a remainder of 608.
Put 6 as the next digit of the answer. 
Result so far: 13546.36
Deduct 5532 from 6140 and we're left with 608.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6080, and continue the process.

Step 11:
When dividing 6080 by 922, we get 6 with a remainder of 548.
Use 6 as the next digit of our solution. 
Result so far: 13546.366
Subtracting 5532 from 6080 leaves us with 548.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5480, and continue the process.

The quotient of the division is 13546.366, and the remainder is 0.0548.
