We're dividing 74123402 by 610 
We want to figure out the number of times 74123402 can be divided by 610.

Let's proceed to step 1:
When dividing 7 by 610, we get 0 with 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.
Bring next digit (4) of the dividend behind the 7 and repeat the process: 74 / 610

Moving on to step 2:
74 divided by 610 is 0 with a remainder of 74.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 74 to get 74.
Bring next digit (1) of the dividend behind the 74 and repeat the process: 741 / 610

Advancing to step 3:
610 can be fit into 741 1 times, resulting in a remainder of 131.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 131 after subtracting 610 from 741.
Grab the next digit (2) from the dividend, add it to 131, then carry on: 1312 / 610

Let's proceed to step 4:
If we divide 1312 by 610, we get 2 and a remainder of 92.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
If we subtract 1220 from 1312, we get 92.
Bring next digit (3) of the dividend behind the 92 and repeat the process: 923 / 610

Moving on to step 5:
610 can be fit into 923 1 times, resulting in a remainder of 313.
The next digit of our result is 1. 
Result so far: 121.0
The remainder is 313 after subtracting 610 from 923.
Include the next digit (4) from the dividend after 313, then repeat: 3134 / 610

Let's proceed to step 6:
The number 610 fits into 3134 5 times, leaving a remainder of 84.
Put 5 as the next digit of the answer. 
Result so far: 1215.0
If we take 3050 away from 3134, we end up with 84.
Append the next digit (0) from the dividend to 84 and continue with: 840 / 610

Moving on to step 7:
If we divide 840 by 610, we get 1 and a remainder of 230.
Use 1 as the next digit of our solution. 
Result so far: 12151.0
The remainder is 230 after subtracting 610 from 840.
Take the next digit (2) from the dividend and append it to 230, then repeat: 2302 / 610

Let's proceed to step 8:
610 goes into 2302 3 times with a remainder of 472.
The number 3 becomes the next digit in our result. 
Result so far: 121513.0
Subtract 1830 from 2302 to get 472.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4720, and continue the process.

Let's proceed to step 9:
610 can be fit into 4720 7 times, resulting in a remainder of 450.
The number 7 becomes the next digit in our result. 
Result so far: 121513.7
The remainder is 450 after subtracting 4270 from 4720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

Step 10:
4500 divided by 610 is 7 with a remainder of 230.
The number 7 becomes the next digit in our result. 
Result so far: 121513.77
Subtract 4270 from 4500 to get 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

After the division, we end up with 121513.77 and a remainder of 0.23.
