We look at the division of 598123 by 80 
We're looking to find how many times 80 goes into 598123.

Let's proceed to step 1:
When dividing 5 by 80, we get 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Take the next digit (9) from the dividend and append it to 5, then repeat: 59 / 80

Going ahead to step 2:
When dividing 59 by 80, we get 0 with a remainder of 59.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 59, we end up with 59.
Take the next digit (8) from the dividend and append it to 59, then repeat: 598 / 80

Moving on to step 3:
80 can be fit into 598 7 times, resulting in a remainder of 38.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
Deduct 560 from 598 and we're left with 38.
Bring next digit (1) of the dividend behind the 38 and repeat the process: 381 / 80

Step 4:
381 divided by 80 is 4 with a remainder of 61.
Use 4 as the next digit of our solution. 
Result so far: 74.0
If we subtract 320 from 381, we get 61.
Include the next digit (2) from the dividend after 61, then repeat: 612 / 80

On to step 5:
If we divide 612 by 80, we get 7 and a remainder of 52.
Record the quotient 7 as the next digit in the result. 
Result so far: 747.0
Subtracting 560 from 612 leaves us with 52.
Append the next digit (3) from the dividend to 52 and continue with: 523 / 80

Going ahead to step 6:
The number 80 fits into 523 6 times, leaving a remainder of 43.
The number 6 becomes the next digit in our result. 
Result so far: 7476.0
Subtract 480 from 523 to get 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Step 7:
80 can be fit into 430 5 times, resulting in a remainder of 30.
The number 5 becomes the next digit in our result. 
Result so far: 7476.5
Subtract 400 from 430 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.

Step 8:
When dividing 300 by 80, we get 3 with a remainder of 60.
Record the quotient 3 as the next digit in the result. 
Result so far: 7476.53
If we take 240 away from 300, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 9:
80 can be fit into 600 7 times, resulting in a remainder of 40.
Put 7 as the next digit of the answer. 
Result so far: 7476.537
If we subtract 560 from 600, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 10:
80 goes into 400 5 times with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 7476.5375
Subtract 400 from 400 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.

Let's proceed to step 11:
0 divided by 80 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 7476.5375
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.

Let's proceed to step 12:
The number 80 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 7476.5375
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 7476.5375 with a remaining 0.0.
