We divide 621742 by 31
Our goal is to divide 621742 by 31.

Advancing to step 1:
6 divided by 31 is 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Append the next digit (2) from the dividend to 6 and continue with: 62 / 31

Going ahead to step 2:
31 goes into 62 2 times with a remainder of 0.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtract 62 from 62 to get 0.
Take the next digit (1) from the dividend and append it to 0, then repeat: 1 / 31

Going ahead to step 3:
If we divide 1 by 31, we get 0 and a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 20.0
Subtract 0 from 1 to get 1.
Include the next digit (7) from the dividend after 1, then repeat: 17 / 31

Moving on to step 4:
31 goes into 17 0 times with a remainder of 17.
Put 0 as the next digit of the answer. 
Result so far: 200.0
Subtract 0 from 17 to get 17.
Fetch the next digit (4) from the dividend, attach it to 17 and continue: 174 / 31

Going ahead to step 5:
When dividing 174 by 31, we get 5 with a remainder of 19.
Use 5 as the next digit of our solution. 
Result so far: 2005.0
The remainder is 19 after subtracting 155 from 174.
Fetch the next digit (2) from the dividend, attach it to 19 and continue: 192 / 31

Step 6:
31 goes into 192 6 times with a remainder of 6.
Record the quotient 6 as the next digit in the result. 
Result so far: 20056.0
Subtract 186 from 192 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 7:
When dividing 60 by 31, we get 1 with a remainder of 29.
Use 1 as the next digit of our solution. 
Result so far: 20056.1
Subtract 31 from 60 to get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

On to step 8:
290 divided by 31 is 9 with a remainder of 11.
Record the quotient 9 as the next digit in the result. 
Result so far: 20056.19
If we subtract 279 from 290, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Going ahead to step 9:
110 divided by 31 is 3 with a remainder of 17.
The number 3 becomes the next digit in our result. 
Result so far: 20056.193
If we subtract 93 from 110, we get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Advancing to step 10:
When dividing 170 by 31, we get 5 with a remainder of 15.
The next digit of our result is 5. 
Result so far: 20056.1935
Subtract 155 from 170 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 11:
31 can be fit into 150 4 times, resulting in a remainder of 26.
Record the quotient 4 as the next digit in the result. 
Result so far: 20056.19354
The remainder is 26 after subtracting 124 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Step 12:
31 can be fit into 260 8 times, resulting in a remainder of 12.
Write down 8 as next digit of the result. 
Result so far: 20056.193548
If we take 248 away from 260, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 13:
31 can be fit into 120 3 times, resulting in a remainder of 27.
Record the quotient 3 as the next digit in the result. 
Result so far: 20056.1935483
The remainder is 27 after subtracting 93 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Going ahead to step 14:
31 can be fit into 270 8 times, resulting in a remainder of 22.
Write down 8 as next digit of the result. 
Result so far: 20056.19354838
Deduct 248 from 270 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

After the division, we end up with 20056.19354838 and a remainder of 2.2e-08.
