We divide 621211 by 31
Our goal is to divide 621211 by 31.

Advancing to step 1:
When dividing 6 by 31, we get 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Grab the next digit (2) from the dividend, add it to 6, then carry on: 62 / 31

On to step 2:
62 divided by 31 is 2 with a remainder of 0.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we subtract 62 from 62, we get 0.
Fetch the next digit (1) from the dividend, attach it to 0 and continue: 1 / 31

Advancing to step 3:
When dividing 1 by 31, we get 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 20.0
The remainder is 1 after subtracting 0 from 1.
Take the next digit (2) from the dividend and append it to 1, then repeat: 12 / 31

Going ahead to step 4:
When dividing 12 by 31, we get 0 with a remainder of 12.
The number 0 becomes the next digit in our result. 
Result so far: 200.0
The remainder is 12 after subtracting 0 from 12.
Grab the next digit (1) from the dividend, add it to 12, then carry on: 121 / 31

Step 5:
121 divided by 31 is 3 with a remainder of 28.
Put 3 as the next digit of the answer. 
Result so far: 2003.0
Deduct 93 from 121 and we're left with 28.
Take the next digit (1) from the dividend and append it to 28, then repeat: 281 / 31

Step 6:
31 can be fit into 281 9 times, resulting in a remainder of 2.
Use 9 as the next digit of our solution. 
Result so far: 20039.0
Subtracting 279 from 281 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 7:
When dividing 20 by 31, we get 0 with a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 20039.0
If we take 0 away from 20, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 8:
31 can be fit into 200 6 times, resulting in a remainder of 14.
Put 6 as the next digit of the answer. 
Result so far: 20039.06
Subtracting 186 from 200 leaves us 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.

Moving on to step 9:
The number 31 fits into 140 4 times, leaving a remainder of 16.
Put 4 as the next digit of the answer. 
Result so far: 20039.064
Subtracting 124 from 140 leaves us 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.

Advancing to step 10:
31 can be fit into 160 5 times, resulting in a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 20039.0645
If we take 155 away from 160, we end up 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.

Moving on to step 11:
31 goes into 50 1 times with a remainder of 19.
The number 1 becomes the next digit in our result. 
Result so far: 20039.06451
Subtracting 31 from 50 leaves us with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Step 12:
The number 31 fits into 190 6 times, leaving a remainder of 4.
Record the quotient 6 as the next digit in the result. 
Result so far: 20039.064516
If we subtract 186 from 190, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 13:
If we divide 40 by 31, we get 1 and a remainder of 9.
Write down 1 as next digit of the result. 
Result so far: 20039.0645161
If we take 31 away from 40, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Moving on to step 14:
The number 31 fits into 90 2 times, leaving a remainder of 28.
Record the quotient 2 as the next digit in the result. 
Result so far: 20039.06451612
Subtract 62 from 90 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Our division results in 20039.06451612 with a remaining 2.8e-08.
