We're dividing 742351 by 12 
We want to figure out the number of times 742351 can be divided by 12.

Advancing to step 1:
12 goes into 7 0 times with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Bring next digit (4) of the dividend behind the 7 and repeat the process: 74 / 12

On to step 2:
The number 12 fits into 74 6 times, leaving a remainder of 2.
Put 6 as the next digit of the answer. 
Result so far: 6.0
Subtract 72 from 74 to get 2.
Append the next digit (2) from the dividend to 2 and continue with: 22 / 12

Advancing to step 3:
12 goes into 22 1 times with a remainder of 10.
Put 1 as the next digit of the answer. 
Result so far: 61.0
If we take 12 away from 22, we end up with 10.
Grab the next digit (3) from the dividend, add it to 10, then carry on: 103 / 12

Step 4:
12 can be fit into 103 8 times, resulting in a remainder of 7.
The number 8 becomes the next digit in our result. 
Result so far: 618.0
Subtract 96 from 103 to get 7.
Append the next digit (5) from the dividend to 7 and continue with: 75 / 12

Step 5:
12 goes into 75 6 times with a remainder of 3.
Put 6 as the next digit of the answer. 
Result so far: 6186.0
Subtracting 72 from 75 leaves us with 3.
Bring next digit (1) of the dividend behind the 3 and repeat the process: 31 / 12

Let's proceed to step 6:
When dividing 31 by 12, we get 2 with a remainder of 7.
The number 2 becomes the next digit in our result. 
Result so far: 61862.0
Subtracting 24 from 31 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 7:
When dividing 70 by 12, we get 5 with a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 61862.5
If we subtract 60 from 70, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 8:
If we divide 100 by 12, we get 8 and a remainder of 4.
Record the quotient 8 as the next digit in the result. 
Result so far: 61862.58
Subtract 96 from 100 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 9:
40 divided by 12 is 3 with a remainder of 4.
Record the quotient 3 as the next digit in the result. 
Result so far: 61862.583
Subtract 36 from 40 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 10:
12 goes into 40 3 times with a remainder of 4.
The next digit of our result is 3. 
Result so far: 61862.5833
If we subtract 36 from 40, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

The final outcome is 61862.5833, with a leftover of 4e-05.
