We divide 7451 by 12
We want to figure out the number of times 7451 can be divided by 12.

Advancing to step 1:
The number 12 fits into 7 0 times, leaving a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Fetch the next digit (4) from the dividend, attach it to 7 and continue: 74 / 12

Let's proceed to step 2:
If we divide 74 by 12, we get 6 and a remainder of 2.
The next digit of our result is 6. 
Result so far: 6.0
Subtracting 72 from 74 leaves us with 2.
Append the next digit (5) from the dividend to 2 and continue with: 25 / 12

Step 3:
25 divided by 12 is 2 with a remainder of 1.
Put 2 as the next digit of the answer. 
Result so far: 62.0
The remainder is 1 after subtracting 24 from 25.
Take the next digit (1) from the dividend and append it to 1, then repeat: 11 / 12

On to step 4:
11 divided by 12 is 0 with a remainder of 11.
The next digit of our result is 0. 
Result so far: 620.0
If we take 0 away from 11, we end up with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Going ahead to step 5:
110 divided by 12 is 9 with a remainder of 2.
Use 9 as the next digit of our solution. 
Result so far: 620.9
Subtracting 108 from 110 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 6:
12 goes into 20 1 times with a remainder of 8.
The number 1 becomes the next digit in our result. 
Result so far: 620.91
Deduct 12 from 20 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.

On to step 7:
12 goes into 80 6 times with a remainder of 8.
Record the quotient 6 as the next digit in the result. 
Result so far: 620.916
If we subtract 72 from 80, we get 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 8:
If we divide 80 by 12, we get 6 and a remainder of 8.
Use 6 as the next digit of our solution. 
Result so far: 620.9166
Subtracting 72 from 80 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.

After the division, we end up with 620.9166 and a remainder of 8e-05.
