Let's divide 749808 by 42
We want to figure out the number of times 749808 can be divided by 42.

Step 1:
When dividing 7 by 42, we get 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Include the next digit (4) from the dividend after 7, then repeat: 74 / 42

Moving on to step 2:
42 goes into 74 1 times with a remainder of 32.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 42 from 74 leaves us with 32.
Fetch the next digit (9) from the dividend, attach it to 32 and continue: 329 / 42

On to step 3:
The number 42 fits into 329 7 times, leaving a remainder of 35.
Use 7 as the next digit of our solution. 
Result so far: 17.0
Subtracting 294 from 329 leaves us with 35.
Include the next digit (8) from the dividend after 35, then repeat: 358 / 42

Going ahead to step 4:
358 divided by 42 is 8 with a remainder of 22.
Put 8 as the next digit of the answer. 
Result so far: 178.0
The remainder is 22 after subtracting 336 from 358.
Fetch the next digit (0) from the dividend, attach it to 22 and continue: 220 / 42

On to step 5:
The number 42 fits into 220 5 times, leaving a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 1785.0
If we subtract 210 from 220, we get 10.
Append the next digit (8) from the dividend to 10 and continue with: 108 / 42

On to step 6:
The number 42 fits into 108 2 times, leaving a remainder of 24.
Write down 2 as next digit of the result. 
Result so far: 17852.0
If we subtract 84 from 108, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 7:
When dividing 240 by 42, we get 5 with a remainder of 30.
Use 5 as the next digit of our solution. 
Result so far: 17852.5
Subtract 210 from 240 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 8:
When dividing 300 by 42, we get 7 with a remainder of 6.
Write down 7 as next digit of the result. 
Result so far: 17852.57
Subtract 294 from 300 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 9:
If we divide 60 by 42, we get 1 and a remainder of 18.
Put 1 as the next digit of the answer. 
Result so far: 17852.571
Subtract 42 from 60 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 10:
42 can be fit into 180 4 times, resulting in a remainder of 12.
The number 4 becomes the next digit in our result. 
Result so far: 17852.5714
If we take 168 away from 180, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 11:
120 divided by 42 is 2 with a remainder of 36.
Use 2 as the next digit of our solution. 
Result so far: 17852.57142
Subtracting 84 from 120 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Let's proceed to step 12:
When dividing 360 by 42, we get 8 with a remainder of 24.
Put 8 as the next digit of the answer. 
Result so far: 17852.571428
If we take 336 away from 360, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 13:
The number 42 fits into 240 5 times, leaving a remainder of 30.
Use 5 as the next digit of our solution. 
Result so far: 17852.5714285
Subtract 210 from 240 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 14:
The number 42 fits into 300 7 times, leaving a remainder of 6.
Use 7 as the next digit of our solution. 
Result so far: 17852.57142857
If we take 294 away from 300, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

The final result is 17852.57142857 with a remainder of 6e-09.
