We're dividing 53879665 by 622 
We want to divide 53879665 by 622.

Going ahead to step 1:
622 goes into 5 0 times with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Bring next digit (3) of the dividend behind the 5 and repeat the process: 53 / 622

Going ahead to step 2:
622 goes into 53 0 times with a remainder of 53.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 53, we end up with 53.
Include the next digit (8) from the dividend after 53, then repeat: 538 / 622

Step 3:
538 divided by 622 is 0 with a remainder of 538.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 538 and we're left with 538.
Append the next digit (7) from the dividend to 538 and continue with: 5387 / 622

Step 4:
622 goes into 5387 8 times with a remainder of 411.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
If we subtract 4976 from 5387, we get 411.
Append the next digit (9) from the dividend to 411 and continue with: 4119 / 622

Step 5:
The number 622 fits into 4119 6 times, leaving a remainder of 387.
Write down 6 as next digit of the result. 
Result so far: 86.0
Subtracting 3732 from 4119 leaves us with 387.
Take the next digit (6) from the dividend and append it to 387, then repeat: 3876 / 622

Moving on to step 6:
622 can be fit into 3876 6 times, resulting in a remainder of 144.
Record the quotient 6 as the next digit in the result. 
Result so far: 866.0
The remainder is 144 after subtracting 3732 from 3876.
Append the next digit (6) from the dividend to 144 and continue with: 1446 / 622

Step 7:
If we divide 1446 by 622, we get 2 and a remainder of 202.
Record the quotient 2 as the next digit in the result. 
Result so far: 8662.0
Subtracting 1244 from 1446 leaves us with 202.
Fetch the next digit (5) from the dividend, attach it to 202 and continue: 2025 / 622

Let's proceed to step 8:
622 goes into 2025 3 times with a remainder of 159.
The number 3 becomes the next digit in our result. 
Result so far: 86623.0
Subtract 1866 from 2025 to get 159.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1590, and continue the process.

Advancing to step 9:
622 goes into 1590 2 times with a remainder of 346.
The number 2 becomes the next digit in our result. 
Result so far: 86623.2
If we take 1244 away from 1590, we end up with 346.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3460, and continue the process.

Going ahead to step 10:
The number 622 fits into 3460 5 times, leaving a remainder of 350.
Record the quotient 5 as the next digit in the result. 
Result so far: 86623.25
Subtracting 3110 from 3460 leaves us with 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

On to step 11:
The number 622 fits into 3500 5 times, leaving a remainder of 390.
The next digit of our result is 5. 
Result so far: 86623.255
The remainder is 390 after subtracting 3110 from 3500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3900, and continue the process.

After the division, we end up with 86623.255 and a remainder of 0.039.
