Let's divide 53760566 by 638
We want to divide 53760566 by 638.

Going ahead to step 1:
If we divide 5 by 638, we get 0 and a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Bring next digit (3) of the dividend behind the 5 and repeat the process: 53 / 638

Moving on to step 2:
638 goes into 53 0 times with a remainder of 53.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 53 and we're left with 53.
Bring next digit (7) of the dividend behind the 53 and repeat the process: 537 / 638

Going ahead to step 3:
The number 638 fits into 537 0 times, leaving a remainder of 537.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 537 to get 537.
Bring next digit (6) of the dividend behind the 537 and repeat the process: 5376 / 638

Moving on to step 4:
638 can be fit into 5376 8 times, resulting in a remainder of 272.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
The remainder is 272 after subtracting 5104 from 5376.
Grab the next digit (0) from the dividend, add it to 272, then carry on: 2720 / 638

On to step 5:
2720 divided by 638 is 4 with a remainder of 168.
The number 4 becomes the next digit in our result. 
Result so far: 84.0
If we subtract 2552 from 2720, we get 168.
Fetch the next digit (5) from the dividend, attach it to 168 and continue: 1685 / 638

Step 6:
When dividing 1685 by 638, we get 2 with a remainder of 409.
Use 2 as the next digit of our solution. 
Result so far: 842.0
If we take 1276 away from 1685, we end up with 409.
Take the next digit (6) from the dividend and append it to 409, then repeat: 4096 / 638

Moving on to step 7:
638 goes into 4096 6 times with a remainder of 268.
Put 6 as the next digit of the answer. 
Result so far: 8426.0
Deduct 3828 from 4096 and we're left with 268.
Fetch the next digit (6) from the dividend, attach it to 268 and continue: 2686 / 638

Let's proceed to step 8:
If we divide 2686 by 638, we get 4 and a remainder of 134.
Put 4 as the next digit of the answer. 
Result so far: 84264.0
If we take 2552 away from 2686, we end up with 134.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1340, and continue the process.

Going ahead to step 9:
If we divide 1340 by 638, we get 2 and a remainder of 64.
Record the quotient 2 as the next digit in the result. 
Result so far: 84264.2
If we subtract 1276 from 1340, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Let's proceed to step 10:
638 goes into 640 1 times with a remainder of 2.
Write down 1 as next digit of the result. 
Result so far: 84264.21
Subtracting 638 from 640 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 11:
If we divide 20 by 638, we get 0 and a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 84264.21
Deduct 0 from 20 and we're left 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.

Moving on to step 12:
638 goes into 200 0 times with a remainder of 200.
The number 0 becomes the next digit in our result. 
Result so far: 84264.21
If we subtract 0 from 200, we get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

The final outcome is 84264.21, with a leftover of 0.002.
