12241874 ÷ 671 
We're looking to find how many times 671 goes into 12241874.

On to step 1:
1 divided by 671 is 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 671

Moving on to step 2:
When dividing 12 by 671, we get 0 with a remainder of 12.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 12 after subtracting 0 from 12.
Fetch the next digit (2) from the dividend, attach it to 12 and continue: 122 / 671

Let's proceed to step 3:
671 goes into 122 0 times with a remainder of 122.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 122 leaves us with 122.
Take the next digit (4) from the dividend and append it to 122, then repeat: 1224 / 671

Moving on to step 4:
671 can be fit into 1224 1 times, resulting in a remainder of 553.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 671 from 1224 and we're left with 553.
Append the next digit (1) from the dividend to 553 and continue with: 5531 / 671

Moving on to step 5:
The number 671 fits into 5531 8 times, leaving a remainder of 163.
Put 8 as the next digit of the answer. 
Result so far: 18.0
The remainder is 163 after subtracting 5368 from 5531.
Bring next digit (8) of the dividend behind the 163 and repeat the process: 1638 / 671

On to step 6:
If we divide 1638 by 671, we get 2 and a remainder of 296.
Write down 2 as next digit of the result. 
Result so far: 182.0
Deduct 1342 from 1638 and we're left with 296.
Append the next digit (7) from the dividend to 296 and continue with: 2967 / 671

On to step 7:
671 goes into 2967 4 times with a remainder of 283.
Put 4 as the next digit of the answer. 
Result so far: 1824.0
If we take 2684 away from 2967, we end up with 283.
Grab the next digit (4) from the dividend, add it to 283, then carry on: 2834 / 671

Step 8:
If we divide 2834 by 671, we get 4 and a remainder of 150.
Use 4 as the next digit of our solution. 
Result so far: 18244.0
Deduct 2684 from 2834 and we're left with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Step 9:
671 goes into 1500 2 times with a remainder of 158.
Put 2 as the next digit of the answer. 
Result so far: 18244.2
Deduct 1342 from 1500 and we're left with 158.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1580, and continue the process.

On to step 10:
671 can be fit into 1580 2 times, resulting in a remainder of 238.
The next digit of our result is 2. 
Result so far: 18244.22
Subtract 1342 from 1580 to get 238.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2380, and continue the process.

The final result is 18244.22 with a remainder of 0.238.
