We're dividing 74105065 by 642 
We want to figure out the number of times 74105065 can be divided by 642.

Step 1:
When dividing 7 by 642, we get 0 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.
Take the next digit (4) from the dividend and append it to 7, then repeat: 74 / 642

Advancing to step 2:
When dividing 74 by 642, we get 0 with a remainder of 74.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 74 after subtracting 0 from 74.
Grab the next digit (1) from the dividend, add it to 74, then carry on: 741 / 642

Advancing to step 3:
The number 642 fits into 741 1 times, leaving a remainder of 99.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 642 from 741 to get 99.
Append the next digit (0) from the dividend to 99 and continue with: 990 / 642

Moving on to step 4:
When dividing 990 by 642, we get 1 with a remainder of 348.
Put 1 as the next digit of the answer. 
Result so far: 11.0
Subtract 642 from 990 to get 348.
Bring next digit (5) of the dividend behind the 348 and repeat the process: 3485 / 642

Let's proceed to step 5:
3485 divided by 642 is 5 with a remainder of 275.
The next digit of our result is 5. 
Result so far: 115.0
Deduct 3210 from 3485 and we're left with 275.
Append the next digit (0) from the dividend to 275 and continue with: 2750 / 642

On to step 6:
The number 642 fits into 2750 4 times, leaving a remainder of 182.
Put 4 as the next digit of the answer. 
Result so far: 1154.0
The remainder is 182 after subtracting 2568 from 2750.
Include the next digit (6) from the dividend after 182, then repeat: 1826 / 642

Let's proceed to step 7:
642 goes into 1826 2 times with a remainder of 542.
Put 2 as the next digit of the answer. 
Result so far: 11542.0
Subtracting 1284 from 1826 leaves us with 542.
Append the next digit (5) from the dividend to 542 and continue with: 5425 / 642

Let's proceed to step 8:
5425 divided by 642 is 8 with a remainder of 289.
Put 8 as the next digit of the answer. 
Result so far: 115428.0
Subtracting 5136 from 5425 leaves us with 289.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2890, and continue the process.

Moving on to step 9:
When dividing 2890 by 642, we get 4 with a remainder of 322.
The number 4 becomes the next digit in our result. 
Result so far: 115428.4
Subtracting 2568 from 2890 leaves us with 322.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3220, and continue the process.

Going ahead to step 10:
3220 divided by 642 is 5 with a remainder of 10.
The next digit of our result is 5. 
Result so far: 115428.45
If we subtract 3210 from 3220, 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.

Advancing to step 11:
The number 642 fits into 100 0 times, leaving a remainder of 100.
The number 0 becomes the next digit in our result. 
Result so far: 115428.45
Deduct 0 from 100 and we're left with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Step 12:
The number 642 fits into 1000 1 times, leaving a remainder of 358.
Put 1 as the next digit of the answer. 
Result so far: 115428.4501
The remainder is 358 after subtracting 642 from 1000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3580, and continue the process.

On to step 13:
3580 divided by 642 is 5 with a remainder of 370.
Put 5 as the next digit of the answer. 
Result so far: 115428.45015
Subtracting 3210 from 3580 leaves us with 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3700, and continue the process.

Step 14:
The number 642 fits into 3700 5 times, leaving a remainder of 490.
Use 5 as the next digit of our solution. 
Result so far: 115428.450155
Subtract 3210 from 3700 to get 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4900, and continue the process.

The quotient of the division is 115428.450155, and the remainder is 4.9e-05.
