Let's divide 648770 by 31
Our goal is to divide 648770 by 31.

Moving on to step 1:
If we divide 6 by 31, we get 0 and 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.
Take the next digit (4) from the dividend and append it to 6, then repeat: 64 / 31

Moving on to step 2:
31 can be fit into 64 2 times, resulting in a remainder of 2.
Write down 2 as next digit of the result. 
Result so far: 2.0
The remainder is 2 after subtracting 62 from 64.
Bring next digit (8) of the dividend behind the 2 and repeat the process: 28 / 31

On to step 3:
28 divided by 31 is 0 with a remainder of 28.
Write down 0 as next digit of the result. 
Result so far: 20.0
Subtract 0 from 28 to get 28.
Grab the next digit (7) from the dividend, add it to 28, then carry on: 287 / 31

Step 4:
31 can be fit into 287 9 times, resulting in a remainder of 8.
Put 9 as the next digit of the answer. 
Result so far: 209.0
If we subtract 279 from 287, we get 8.
Grab the next digit (7) from the dividend, add it to 8, then carry on: 87 / 31

Let's proceed to step 5:
31 can be fit into 87 2 times, resulting in a remainder of 25.
Record the quotient 2 as the next digit in the result. 
Result so far: 2092.0
If we subtract 62 from 87, we get 25.
Grab the next digit (0) from the dividend, add it to 25, then carry on: 250 / 31

On to step 6:
31 goes into 250 8 times with a remainder of 2.
Put 8 as the next digit of the answer. 
Result so far: 20928.0
Subtracting 248 from 250 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.

Going ahead to step 7:
If we divide 20 by 31, we get 0 and a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 20928.0
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 8:
200 divided by 31 is 6 with a remainder of 14.
Record the quotient 6 as the next digit in the result. 
Result so far: 20928.06
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.

Advancing to step 9:
140 divided by 31 is 4 with a remainder of 16.
Record the quotient 4 as the next digit in the result. 
Result so far: 20928.064
Deduct 124 from 140 and we're left 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.

Moving on to step 10:
If we divide 160 by 31, we get 5 and a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 20928.0645
Subtract 155 from 160 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 11:
If we divide 50 by 31, we get 1 and a remainder of 19.
The next digit of our result is 1. 
Result so far: 20928.06451
The remainder is 19 after subtracting 31 from 50.
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 12:
When dividing 190 by 31, we get 6 with a remainder of 4.
Use 6 as the next digit of our solution. 
Result so far: 20928.064516
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.

Advancing to step 13:
The number 31 fits into 40 1 times, leaving a remainder of 9.
Record the quotient 1 as the next digit in the result. 
Result so far: 20928.0645161
If we subtract 31 from 40, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 14:
90 divided by 31 is 2 with a remainder of 28.
The next digit of our result is 2. 
Result so far: 20928.06451612
If we subtract 62 from 90, we 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.

In conclusion, the division gives 20928.06451612 with a balance of 2.8e-08.
