78831630 ÷ 75 
We want to figure out the number of times 78831630 can be divided by 75.

On to step 1:
75 goes into 7 0 times with 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.
Fetch the next digit (8) from the dividend, attach it to 7 and continue: 78 / 75

Step 2:
75 goes into 78 1 times with a remainder of 3.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 75 from 78, we get 3.
Bring next digit (8) of the dividend behind the 3 and repeat the process: 38 / 75

Step 3:
If we divide 38 by 75, we get 0 and a remainder of 38.
Write down 0 as next digit of the result. 
Result so far: 10.0
Deduct 0 from 38 and we're left with 38.
Include the next digit (3) from the dividend after 38, then repeat: 383 / 75

Step 4:
When dividing 383 by 75, we get 5 with a remainder of 8.
The number 5 becomes the next digit in our result. 
Result so far: 105.0
Subtracting 375 from 383 leaves us with 8.
Include the next digit (1) from the dividend after 8, then repeat: 81 / 75

On to step 5:
When dividing 81 by 75, we get 1 with a remainder of 6.
Put 1 as the next digit of the answer. 
Result so far: 1051.0
Subtracting 75 from 81 leaves us with 6.
Include the next digit (6) from the dividend after 6, then repeat: 66 / 75

On to step 6:
66 divided by 75 is 0 with a remainder of 66.
Use 0 as the next digit of our solution. 
Result so far: 10510.0
If we subtract 0 from 66, we get 66.
Take the next digit (3) from the dividend and append it to 66, then repeat: 663 / 75

Step 7:
If we divide 663 by 75, we get 8 and a remainder of 63.
The next digit of our result is 8. 
Result so far: 105108.0
Subtracting 600 from 663 leaves us with 63.
Fetch the next digit (0) from the dividend, attach it to 63 and continue: 630 / 75

Moving on to step 8:
When dividing 630 by 75, we get 8 with a remainder of 30.
Write down 8 as next digit of the result. 
Result so far: 1051088.0
Deduct 600 from 630 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 9:
When dividing 300 by 75, we get 4 with a remainder of 0.
Put 4 as the next digit of the answer. 
Result so far: 1051088.4
The remainder is 0 after subtracting 300 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 10:
The number 75 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 1051088.4
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 11:
75 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 1051088.4
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 1051088.4 with a remainder of 0.0.
