Let's divide 53677674 by 80
We're looking to find how many times 80 goes into 53677674.

Step 1:
80 can be fit into 5 0 times, resulting in a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Grab the next digit (3) from the dividend, add it to 5, then carry on: 53 / 80

Let's proceed to step 2:
80 can be fit into 53 0 times, resulting in a remainder of 53.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 53 after subtracting 0 from 53.
Fetch the next digit (6) from the dividend, attach it to 53 and continue: 536 / 80

Let's proceed to step 3:
If we divide 536 by 80, we get 6 and a remainder of 56.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
The remainder is 56 after subtracting 480 from 536.
Append the next digit (7) from the dividend to 56 and continue with: 567 / 80

Going ahead to step 4:
80 goes into 567 7 times with a remainder of 7.
The number 7 becomes the next digit in our result. 
Result so far: 67.0
Subtract 560 from 567 to get 7.
Append the next digit (7) from the dividend to 7 and continue with: 77 / 80

Advancing to step 5:
The number 80 fits into 77 0 times, leaving a remainder of 77.
Put 0 as the next digit of the answer. 
Result so far: 670.0
The remainder is 77 after subtracting 0 from 77.
Include the next digit (6) from the dividend after 77, then repeat: 776 / 80

Going ahead to step 6:
776 divided by 80 is 9 with a remainder of 56.
The number 9 becomes the next digit in our result. 
Result so far: 6709.0
The remainder is 56 after subtracting 720 from 776.
Take the next digit (7) from the dividend and append it to 56, then repeat: 567 / 80

Advancing to step 7:
80 goes into 567 7 times with a remainder of 7.
Use 7 as the next digit of our solution. 
Result so far: 67097.0
Subtracting 560 from 567 leaves us with 7.
Fetch the next digit (4) from the dividend, attach it to 7 and continue: 74 / 80

Going ahead to step 8:
80 goes into 74 0 times with a remainder of 74.
Write down 0 as next digit of the result. 
Result so far: 670970.0
Deduct 0 from 74 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.

Moving on to step 9:
80 can be fit into 740 9 times, resulting in a remainder of 20.
Write down 9 as next digit of the result. 
Result so far: 670970.9
Subtract 720 from 740 to 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.

On to step 10:
If we divide 200 by 80, we get 2 and a remainder of 40.
Record the quotient 2 as the next digit in the result. 
Result so far: 670970.92
Subtracting 160 from 200 leaves us 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 11:
400 divided by 80 is 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 670970.925
If we take 400 away from 400, 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.

Moving on to step 12:
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: 670970.925
Subtracting 0 from 0 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.

Moving on to step 13:
0 divided by 80 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 670970.925
Subtracting 0 from 0 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.

The final outcome is 670970.925, with a leftover of 0.0.
