We look at the division of 63548406 by 621 
Our goal is to divide 63548406 by 621.

Step 1:
621 can be fit into 6 0 times, resulting in a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Fetch the next digit (3) from the dividend, attach it to 6 and continue: 63 / 621

Moving on to step 2:
621 goes into 63 0 times with a remainder of 63.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 63, we end up with 63.
Fetch the next digit (5) from the dividend, attach it to 63 and continue: 635 / 621

Moving on to step 3:
If we divide 635 by 621, we get 1 and a remainder of 14.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 621 from 635 and we're left with 14.
Append the next digit (4) from the dividend to 14 and continue with: 144 / 621

Step 4:
If we divide 144 by 621, we get 0 and a remainder of 144.
Put 0 as the next digit of the answer. 
Result so far: 10.0
If we subtract 0 from 144, we get 144.
Grab the next digit (8) from the dividend, add it to 144, then carry on: 1448 / 621

Moving on to step 5:
621 goes into 1448 2 times with a remainder of 206.
Write down 2 as next digit of the result. 
Result so far: 102.0
If we subtract 1242 from 1448, we get 206.
Fetch the next digit (4) from the dividend, attach it to 206 and continue: 2064 / 621

Moving on to step 6:
621 goes into 2064 3 times with a remainder of 201.
Write down 3 as next digit of the result. 
Result so far: 1023.0
Deduct 1863 from 2064 and we're left with 201.
Grab the next digit (0) from the dividend, add it to 201, then carry on: 2010 / 621

Step 7:
When dividing 2010 by 621, we get 3 with a remainder of 147.
Use 3 as the next digit of our solution. 
Result so far: 10233.0
The remainder is 147 after subtracting 1863 from 2010.
Take the next digit (6) from the dividend and append it to 147, then repeat: 1476 / 621

Let's proceed to step 8:
If we divide 1476 by 621, we get 2 and a remainder of 234.
The next digit of our result is 2. 
Result so far: 102332.0
Subtract 1242 from 1476 to get 234.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2340, and continue the process.

Step 9:
If we divide 2340 by 621, we get 3 and a remainder of 477.
The number 3 becomes the next digit in our result. 
Result so far: 102332.3
If we take 1863 away from 2340, we end up with 477.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4770, and continue the process.

Going ahead to step 10:
4770 divided by 621 is 7 with a remainder of 423.
Record the quotient 7 as the next digit in the result. 
Result so far: 102332.37
The remainder is 423 after subtracting 4347 from 4770.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4230, and continue the process.

Step 11:
The number 621 fits into 4230 6 times, leaving a remainder of 504.
The next digit of our result is 6. 
Result so far: 102332.376
Subtracting 3726 from 4230 leaves us with 504.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5040, and continue the process.

On to step 12:
5040 divided by 621 is 8 with a remainder of 72.
The number 8 becomes the next digit in our result. 
Result so far: 102332.3768
If we subtract 4968 from 5040, we get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Let's proceed to step 13:
If we divide 720 by 621, we get 1 and a remainder of 99.
Use 1 as the next digit of our solution. 
Result so far: 102332.37681
The remainder is 99 after subtracting 621 from 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 990, and continue the process.

Moving on to step 14:
990 divided by 621 is 1 with a remainder of 369.
Write down 1 as next digit of the result. 
Result so far: 102332.376811
The remainder is 369 after subtracting 621 from 990.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3690, and continue the process.

After the division, we end up with 102332.376811 and a remainder of 3.69e-05.
