We look at the division of 20542613 by 648 
We want to divide 20542613 by 648.

On to step 1:
When dividing 2 by 648, we get 0 with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Include the next digit (0) from the dividend after 2, then repeat: 20 / 648

On to step 2:
648 can be fit into 20 0 times, resulting in a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 20 and we're left with 20.
Grab the next digit (5) from the dividend, add it to 20, then carry on: 205 / 648

Step 3:
When dividing 205 by 648, we get 0 with a remainder of 205.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 205 and we're left with 205.
Append the next digit (4) from the dividend to 205 and continue with: 2054 / 648

Let's proceed to step 4:
648 goes into 2054 3 times with a remainder of 110.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Deduct 1944 from 2054 and we're left with 110.
Bring next digit (2) of the dividend behind the 110 and repeat the process: 1102 / 648

On to step 5:
The number 648 fits into 1102 1 times, leaving a remainder of 454.
The next digit of our result is 1. 
Result so far: 31.0
Subtracting 648 from 1102 leaves us with 454.
Fetch the next digit (6) from the dividend, attach it to 454 and continue: 4546 / 648

On to step 6:
648 can be fit into 4546 7 times, resulting in a remainder of 10.
The next digit of our result is 7. 
Result so far: 317.0
Subtracting 4536 from 4546 leaves us with 10.
Bring next digit (1) of the dividend behind the 10 and repeat the process: 101 / 648

Advancing to step 7:
The number 648 fits into 101 0 times, leaving a remainder of 101.
Record the quotient 0 as the next digit in the result. 
Result so far: 3170.0
Subtracting 0 from 101 leaves us with 101.
Take the next digit (3) from the dividend and append it to 101, then repeat: 1013 / 648

Step 8:
648 can be fit into 1013 1 times, resulting in a remainder of 365.
Record the quotient 1 as the next digit in the result. 
Result so far: 31701.0
If we subtract 648 from 1013, we get 365.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3650, and continue the process.

Let's proceed to step 9:
648 goes into 3650 5 times with a remainder of 410.
Put 5 as the next digit of the answer. 
Result so far: 31701.5
If we take 3240 away from 3650, we end up with 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4100, and continue the process.

Step 10:
If we divide 4100 by 648, we get 6 and a remainder of 212.
The number 6 becomes the next digit in our result. 
Result so far: 31701.56
Subtract 3888 from 4100 to get 212.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2120, and continue the process.

Step 11:
When dividing 2120 by 648, we get 3 with a remainder of 176.
Record the quotient 3 as the next digit in the result. 
Result so far: 31701.563
The remainder is 176 after subtracting 1944 from 2120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

Let's proceed to step 12:
If we divide 1760 by 648, we get 2 and a remainder of 464.
The number 2 becomes the next digit in our result. 
Result so far: 31701.5632
Deduct 1296 from 1760 and we're left with 464.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4640, and continue the process.

On to step 13:
If we divide 4640 by 648, we get 7 and a remainder of 104.
Put 7 as the next digit of the answer. 
Result so far: 31701.56327
Deduct 4536 from 4640 and we're left with 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Let's proceed to step 14:
If we divide 1040 by 648, we get 1 and a remainder of 392.
Use 1 as the next digit of our solution. 
Result so far: 31701.563271
Subtract 648 from 1040 to get 392.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3920, and continue the process.

Advancing to step 15:
648 goes into 3920 6 times with a remainder of 32.
Record the quotient 6 as the next digit in the result. 
Result so far: 31701.5632716
The remainder is 32 after subtracting 3888 from 3920.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 16:
When dividing 320 by 648, we get 0 with a remainder of 320.
Write down 0 as next digit of the result. 
Result so far: 31701.5632716
Deduct 0 from 320 and we're left with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

After the division, we end up with 31701.5632716 and a remainder of 3.2e-07.
