We're dividing 75042061 by 502 
We want to figure out the number of times 75042061 can be divided by 502.

Let's proceed to step 1:
The number 502 fits into 7 0 times, leaving a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Grab the next digit (5) from the dividend, add it to 7, then carry on: 75 / 502

Advancing to step 2:
75 divided by 502 is 0 with a remainder of 75.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 75 after subtracting 0 from 75.
Append the next digit (0) from the dividend to 75 and continue with: 750 / 502

Moving on to step 3:
502 can be fit into 750 1 times, resulting in a remainder of 248.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 502 from 750 leaves us with 248.
Grab the next digit (4) from the dividend, add it to 248, then carry on: 2484 / 502

Step 4:
2484 divided by 502 is 4 with a remainder of 476.
Use 4 as the next digit of our solution. 
Result so far: 14.0
Subtracting 2008 from 2484 leaves us with 476.
Grab the next digit (2) from the dividend, add it to 476, then carry on: 4762 / 502

On to step 5:
The number 502 fits into 4762 9 times, leaving a remainder of 244.
The next digit of our result is 9. 
Result so far: 149.0
Subtract 4518 from 4762 to get 244.
Fetch the next digit (0) from the dividend, attach it to 244 and continue: 2440 / 502

Step 6:
The number 502 fits into 2440 4 times, leaving a remainder of 432.
Use 4 as the next digit of our solution. 
Result so far: 1494.0
Subtract 2008 from 2440 to get 432.
Append the next digit (6) from the dividend to 432 and continue with: 4326 / 502

Step 7:
When dividing 4326 by 502, we get 8 with a remainder of 310.
The next digit of our result is 8. 
Result so far: 14948.0
Subtracting 4016 from 4326 leaves us with 310.
Append the next digit (1) from the dividend to 310 and continue with: 3101 / 502

Step 8:
The number 502 fits into 3101 6 times, leaving a remainder of 89.
The next digit of our result is 6. 
Result so far: 149486.0
Subtracting 3012 from 3101 leaves us with 89.
Since there are no more digits in the dividend, we add a zero to the remainder making it 890, and continue the process.

Going ahead to step 9:
The number 502 fits into 890 1 times, leaving a remainder of 388.
Put 1 as the next digit of the answer. 
Result so far: 149486.1
Subtract 502 from 890 to get 388.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3880, and continue the process.

Let's proceed to step 10:
The number 502 fits into 3880 7 times, leaving a remainder of 366.
Put 7 as the next digit of the answer. 
Result so far: 149486.17
Deduct 3514 from 3880 and we're left with 366.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3660, and continue the process.

Going ahead to step 11:
3660 divided by 502 is 7 with a remainder of 146.
Write down 7 as next digit of the result. 
Result so far: 149486.177
If we take 3514 away from 3660, we end up with 146.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1460, and continue the process.

The final outcome is 149486.177, with a leftover of 0.0146.
