Let's divide 988402 by 80
Let's see how many times 80 fits into 988402.

Step 1:
80 can be fit into 9 0 times, resulting in a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Include the next digit (8) from the dividend after 9, then repeat: 98 / 80

On to step 2:
80 goes into 98 1 times with a remainder of 18.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 80 from 98, we get 18.
Grab the next digit (8) from the dividend, add it to 18, then carry on: 188 / 80

Let's proceed to step 3:
80 goes into 188 2 times with a remainder of 28.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
If we subtract 160 from 188, we get 28.
Include the next digit (4) from the dividend after 28, then repeat: 284 / 80

Step 4:
80 can be fit into 284 3 times, resulting in a remainder of 44.
Write down 3 as next digit of the result. 
Result so far: 123.0
The remainder is 44 after subtracting 240 from 284.
Include the next digit (0) from the dividend after 44, then repeat: 440 / 80

Step 5:
80 can be fit into 440 5 times, resulting in a remainder of 40.
Write down 5 as next digit of the result. 
Result so far: 1235.0
The remainder is 40 after subtracting 400 from 440.
Fetch the next digit (2) from the dividend, attach it to 40 and continue: 402 / 80

Step 6:
80 goes into 402 5 times with a remainder of 2.
Use 5 as the next digit of our solution. 
Result so far: 12355.0
Subtract 400 from 402 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 7:
If we divide 20 by 80, we get 0 and a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 12355.0
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 8:
The number 80 fits into 200 2 times, leaving a remainder of 40.
The number 2 becomes the next digit in our result. 
Result so far: 12355.02
Deduct 160 from 200 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 9:
When dividing 400 by 80, we get 5 with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 12355.025
Subtracting 400 from 400 leaves us 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.

Let's proceed to step 10:
If we divide 0 by 80, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 12355.025
Subtract 0 from 0 to 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.

Going ahead to step 11:
If we divide 0 by 80, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 12355.025
Subtract 0 from 0 to 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.

Our division results in 12355.025 with a remaining 0.0.
