125801 divided by 12 
We're looking to find how many times 12 goes into 125801.

On to step 1:
If we divide 1 by 12, we get 0 and a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Grab the next digit (2) from the dividend, add it to 1, then carry on: 12 / 12

On to step 2:
If we divide 12 by 12, we get 1 and a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 12 from 12 leaves us with 0.
Append the next digit (5) from the dividend to 0 and continue with: 5 / 12

On to step 3:
The number 12 fits into 5 0 times, leaving a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 10.0
If we subtract 0 from 5, we get 5.
Bring next digit (8) of the dividend behind the 5 and repeat the process: 58 / 12

Going ahead to step 4:
When dividing 58 by 12, we get 4 with a remainder of 10.
Record the quotient 4 as the next digit in the result. 
Result so far: 104.0
If we subtract 48 from 58, we get 10.
Take the next digit (0) from the dividend and append it to 10, then repeat: 100 / 12

Going ahead to step 5:
When dividing 100 by 12, we get 8 with a remainder of 4.
The next digit of our result is 8. 
Result so far: 1048.0
The remainder is 4 after subtracting 96 from 100.
Take the next digit (1) from the dividend and append it to 4, then repeat: 41 / 12

Let's proceed to step 6:
The number 12 fits into 41 3 times, leaving a remainder of 5.
Record the quotient 3 as the next digit in the result. 
Result so far: 10483.0
If we take 36 away from 41, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 7:
If we divide 50 by 12, we get 4 and a remainder of 2.
The next digit of our result is 4. 
Result so far: 10483.4
The remainder is 2 after subtracting 48 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 8:
The number 12 fits into 20 1 times, leaving a remainder of 8.
Write down 1 as next digit of the result. 
Result so far: 10483.41
Subtracting 12 from 20 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 9:
12 goes into 80 6 times with a remainder of 8.
Put 6 as the next digit of the answer. 
Result so far: 10483.416
Deduct 72 from 80 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 10:
12 goes into 80 6 times with a remainder of 8.
The number 6 becomes the next digit in our result. 
Result so far: 10483.4166
The remainder is 8 after subtracting 72 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The final result is 10483.4166 with a remainder of 8e-05.
