623548 ÷ 31 
Our goal is to divide 623548 by 31.

Step 1:
31 goes into 6 0 times with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Take the next digit (2) from the dividend and append it to 6, then repeat: 62 / 31

Advancing to step 2:
The number 31 fits into 62 2 times, leaving a remainder of 0.
The next digit of our result is 2. 
Result so far: 2.0
If we subtract 62 from 62, we get 0.
Take the next digit (3) from the dividend and append it to 0, then repeat: 3 / 31

Advancing to step 3:
31 can be fit into 3 0 times, resulting in a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 20.0
If we subtract 0 from 3, we get 3.
Take the next digit (5) from the dividend and append it to 3, then repeat: 35 / 31

Step 4:
31 goes into 35 1 times with a remainder of 4.
Put 1 as the next digit of the answer. 
Result so far: 201.0
If we take 31 away from 35, we end up with 4.
Fetch the next digit (4) from the dividend, attach it to 4 and continue: 44 / 31

On to step 5:
If we divide 44 by 31, we get 1 and a remainder of 13.
Put 1 as the next digit of the answer. 
Result so far: 2011.0
If we take 31 away from 44, we end up with 13.
Bring next digit (8) of the dividend behind the 13 and repeat the process: 138 / 31

Step 6:
31 goes into 138 4 times with a remainder of 14.
The next digit of our result is 4. 
Result so far: 20114.0
Deduct 124 from 138 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 7:
When dividing 140 by 31, we get 4 with a remainder of 16.
The next digit of our result is 4. 
Result so far: 20114.4
If we take 124 away from 140, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 8:
The number 31 fits into 160 5 times, leaving a remainder of 5.
The next digit of our result is 5. 
Result so far: 20114.45
Deduct 155 from 160 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 9:
31 can be fit into 50 1 times, resulting in a remainder of 19.
The next digit of our result is 1. 
Result so far: 20114.451
Subtract 31 from 50 to get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Moving on to step 10:
31 can be fit into 190 6 times, resulting in a remainder of 4.
The next digit of our result is 6. 
Result so far: 20114.4516
If we take 186 away from 190, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 11:
When dividing 40 by 31, we get 1 with a remainder of 9.
Write down 1 as next digit of the result. 
Result so far: 20114.45161
The remainder is 9 after subtracting 31 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Step 12:
90 divided by 31 is 2 with a remainder of 28.
Record the quotient 2 as the next digit in the result. 
Result so far: 20114.451612
Subtracting 62 from 90 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

On to step 13:
280 divided by 31 is 9 with a remainder of 1.
Write down 9 as next digit of the result. 
Result so far: 20114.4516129
The remainder is 1 after subtracting 279 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 14:
When dividing 10 by 31, we get 0 with a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 20114.4516129
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The final result is 20114.4516129 with a remainder of 1e-08.
