We're dividing 3874964 by 80 
Our goal is to divide 3874964 by 80.

Going ahead to step 1:
3 divided by 80 is 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Grab the next digit (8) from the dividend, add it to 3, then carry on: 38 / 80

Let's proceed to step 2:
The number 80 fits into 38 0 times, leaving a remainder of 38.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 38 to get 38.
Append the next digit (7) from the dividend to 38 and continue with: 387 / 80

Going ahead to step 3:
If we divide 387 by 80, we get 4 and a remainder of 67.
Put 4 as the next digit of the answer. 
Result so far: 4.0
If we subtract 320 from 387, we get 67.
Fetch the next digit (4) from the dividend, attach it to 67 and continue: 674 / 80

On to step 4:
80 goes into 674 8 times with a remainder of 34.
Put 8 as the next digit of the answer. 
Result so far: 48.0
Deduct 640 from 674 and we're left with 34.
Take the next digit (9) from the dividend and append it to 34, then repeat: 349 / 80

Going ahead to step 5:
When dividing 349 by 80, we get 4 with a remainder of 29.
Put 4 as the next digit of the answer. 
Result so far: 484.0
If we subtract 320 from 349, we get 29.
Take the next digit (6) from the dividend and append it to 29, then repeat: 296 / 80

Step 6:
296 divided by 80 is 3 with a remainder of 56.
Write down 3 as next digit of the result. 
Result so far: 4843.0
Deduct 240 from 296 and we're left with 56.
Append the next digit (4) from the dividend to 56 and continue with: 564 / 80

Moving on to step 7:
If we divide 564 by 80, we get 7 and a remainder of 4.
Put 7 as the next digit of the answer. 
Result so far: 48437.0
If we subtract 560 from 564, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 8:
The number 80 fits into 40 0 times, leaving a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 48437.0
Subtracting 0 from 40 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.

Step 9:
400 divided by 80 is 5 with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 48437.05
Deduct 400 from 400 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.

Moving on to step 10:
When dividing 0 by 80, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 48437.05
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.

Let's proceed to step 11:
80 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 48437.05
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.

After the division, we end up with 48437.05 and a remainder of 0.0.
