Let's divide 749888 by 80
Let's see how many times 80 fits into 749888.

Step 1:
When dividing 7 by 80, we get 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Grab the next digit (4) from the dividend, add it to 7, then carry on: 74 / 80

Step 2:
The number 80 fits into 74 0 times, leaving a remainder of 74.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 74 after subtracting 0 from 74.
Grab the next digit (9) from the dividend, add it to 74, then carry on: 749 / 80

Step 3:
The number 80 fits into 749 9 times, leaving a remainder of 29.
The next digit of our result is 9. 
Result so far: 9.0
The remainder is 29 after subtracting 720 from 749.
Include the next digit (8) from the dividend after 29, then repeat: 298 / 80

Let's proceed to step 4:
80 goes into 298 3 times with a remainder of 58.
Use 3 as the next digit of our solution. 
Result so far: 93.0
If we subtract 240 from 298, we get 58.
Take the next digit (8) from the dividend and append it to 58, then repeat: 588 / 80

On to step 5:
When dividing 588 by 80, we get 7 with a remainder of 28.
Write down 7 as next digit of the result. 
Result so far: 937.0
If we subtract 560 from 588, we get 28.
Include the next digit (8) from the dividend after 28, then repeat: 288 / 80

On to step 6:
The number 80 fits into 288 3 times, leaving a remainder of 48.
Use 3 as the next digit of our solution. 
Result so far: 9373.0
If we subtract 240 from 288, we get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Advancing to step 7:
If we divide 480 by 80, we get 6 and a remainder of 0.
Use 6 as the next digit of our solution. 
Result so far: 9373.6
Deduct 480 from 480 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.

Step 8:
If we divide 0 by 80, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 9373.6
If we take 0 away from 0, we end up 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.

Step 9:
When dividing 0 by 80, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 9373.6
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 quotient of the division is 9373.6, and the remainder is 0.0.
