637834 ÷ 80 
We want to figure out the number of times 637834 can be divided by 80.

Going ahead to step 1:
6 divided by 80 is 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Take the next digit (3) from the dividend and append it to 6, then repeat: 63 / 80

Advancing to step 2:
80 goes into 63 0 times with a remainder of 63.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 63, we end up with 63.
Grab the next digit (7) from the dividend, add it to 63, then carry on: 637 / 80

Moving on to step 3:
The number 80 fits into 637 7 times, leaving a remainder of 77.
Put 7 as the next digit of the answer. 
Result so far: 7.0
Deduct 560 from 637 and we're left with 77.
Take the next digit (8) from the dividend and append it to 77, then repeat: 778 / 80

Step 4:
If we divide 778 by 80, we get 9 and a remainder of 58.
Put 9 as the next digit of the answer. 
Result so far: 79.0
Subtracting 720 from 778 leaves us with 58.
Include the next digit (3) from the dividend after 58, then repeat: 583 / 80

Step 5:
The number 80 fits into 583 7 times, leaving a remainder of 23.
Write down 7 as next digit of the result. 
Result so far: 797.0
If we take 560 away from 583, we end up with 23.
Grab the next digit (4) from the dividend, add it to 23, then carry on: 234 / 80

Step 6:
234 divided by 80 is 2 with a remainder of 74.
The number 2 becomes the next digit in our result. 
Result so far: 7972.0
Deduct 160 from 234 and we're left with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Advancing to step 7:
The number 80 fits into 740 9 times, leaving a remainder of 20.
Use 9 as the next digit of our solution. 
Result so far: 7972.9
The remainder is 20 after subtracting 720 from 740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 8:
The number 80 fits into 200 2 times, leaving a remainder of 40.
Write down 2 as next digit of the result. 
Result so far: 7972.92
The remainder is 40 after subtracting 160 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 9:
400 divided by 80 is 5 with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 7972.925
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.

Advancing to step 10:
80 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 7972.925
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.

Moving on to step 11:
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: 7972.925
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.

The final result is 7972.925 with a remainder of 0.0.
