623972 ÷ 31 
We want to divide 623972 by 31.

On to step 1:
When dividing 6 by 31, we get 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Append the next digit (2) from the dividend to 6 and continue with: 62 / 31

Advancing to step 2:
31 goes into 62 2 times with a remainder of 0.
The next digit of our result is 2. 
Result so far: 2.0
Deduct 62 from 62 and we're left with 0.
Fetch the next digit (3) from the dividend, attach it to 0 and continue: 3 / 31

Step 3:
When dividing 3 by 31, we get 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 20.0
Subtract 0 from 3 to get 3.
Take the next digit (9) from the dividend and append it to 3, then repeat: 39 / 31

Advancing to step 4:
If we divide 39 by 31, we get 1 and a remainder of 8.
Use 1 as the next digit of our solution. 
Result so far: 201.0
The remainder is 8 after subtracting 31 from 39.
Bring next digit (7) of the dividend behind the 8 and repeat the process: 87 / 31

Step 5:
When dividing 87 by 31, we get 2 with a remainder of 25.
The number 2 becomes the next digit in our result. 
Result so far: 2012.0
Subtract 62 from 87 to get 25.
Bring next digit (2) of the dividend behind the 25 and repeat the process: 252 / 31

On to step 6:
The number 31 fits into 252 8 times, leaving a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 20128.0
Deduct 248 from 252 and we're left 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.

Moving on to step 7:
31 goes into 40 1 times with a remainder of 9.
The next digit of our result is 1. 
Result so far: 20128.1
Subtracting 31 from 40 leaves us 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.

Going ahead to step 8:
If we divide 90 by 31, we get 2 and a remainder of 28.
Write down 2 as next digit of the result. 
Result so far: 20128.12
The remainder is 28 after subtracting 62 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Advancing to step 9:
31 goes into 280 9 times with a remainder of 1.
Use 9 as the next digit of our solution. 
Result so far: 20128.129
Subtracting 279 from 280 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 10:
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: 20128.129
Deduct 0 from 10 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 11:
100 divided by 31 is 3 with a remainder of 7.
Put 3 as the next digit of the answer. 
Result so far: 20128.12903
If we take 93 away from 100, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Step 12:
If we divide 70 by 31, we get 2 and a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 20128.129032
Subtracting 62 from 70 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 13:
The number 31 fits into 80 2 times, leaving a remainder of 18.
The next digit of our result is 2. 
Result so far: 20128.1290322
Subtracting 62 from 80 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

In conclusion, the division gives 20128.1290322 with a balance of 1.8e-07.
