We divide 637861 by 80
We want to figure out the number of times 637861 can be divided by 80.

Let's proceed to step 1:
80 can be fit into 6 0 times, resulting in a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Take the next digit (3) from the dividend and append it to 6, then repeat: 63 / 80

Going ahead to step 2:
When dividing 63 by 80, we get 0 with a remainder of 63.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 63 to get 63.
Grab the next digit (7) from the dividend, add it to 63, then carry on: 637 / 80

On to step 3:
80 can be fit into 637 7 times, resulting in a remainder of 77.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
The remainder is 77 after subtracting 560 from 637.
Take the next digit (8) from the dividend and append it to 77, then repeat: 778 / 80

Step 4:
80 can be fit into 778 9 times, resulting in a remainder of 58.
The next digit of our result is 9. 
Result so far: 79.0
Subtract 720 from 778 to get 58.
Include the next digit (6) from the dividend after 58, then repeat: 586 / 80

Let's proceed to step 5:
80 goes into 586 7 times with a remainder of 26.
Record the quotient 7 as the next digit in the result. 
Result so far: 797.0
Deduct 560 from 586 and we're left with 26.
Take the next digit (1) from the dividend and append it to 26, then repeat: 261 / 80

Going ahead to step 6:
80 can be fit into 261 3 times, resulting in a remainder of 21.
The next digit of our result is 3. 
Result so far: 7973.0
The remainder is 21 after subtracting 240 from 261.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Let's proceed to step 7:
When dividing 210 by 80, we get 2 with a remainder of 50.
Record the quotient 2 as the next digit in the result. 
Result so far: 7973.2
If we take 160 away from 210, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 8:
80 can be fit into 500 6 times, resulting in a remainder of 20.
Write down 6 as next digit of the result. 
Result so far: 7973.26
Subtracting 480 from 500 leaves us with 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 9:
When dividing 200 by 80, we get 2 with a remainder of 40.
The next digit of our result is 2. 
Result so far: 7973.262
If we take 160 away from 200, we end up 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.

Step 10:
If we divide 400 by 80, we get 5 and a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 7973.2625
If we subtract 400 from 400, 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.

On to step 11:
80 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 7973.2625
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.
The number 0 becomes the next digit in our result. 
Result so far: 7973.2625
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 outcome is 7973.2625, with a leftover of 0.0.
