Let's divide 612308 by 31
We want to figure out the number of times 612308 can be divided by 31.

Let's proceed to step 1:
If we divide 6 by 31, we get 0 and a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Bring next digit (1) of the dividend behind the 6 and repeat the process: 61 / 31

Step 2:
31 can be fit into 61 1 times, resulting in a remainder of 30.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 31 from 61, we get 30.
Fetch the next digit (2) from the dividend, attach it to 30 and continue: 302 / 31

Step 3:
The number 31 fits into 302 9 times, leaving a remainder of 23.
Use 9 as the next digit of our solution. 
Result so far: 19.0
The remainder is 23 after subtracting 279 from 302.
Append the next digit (3) from the dividend to 23 and continue with: 233 / 31

Advancing to step 4:
The number 31 fits into 233 7 times, leaving a remainder of 16.
The number 7 becomes the next digit in our result. 
Result so far: 197.0
The remainder is 16 after subtracting 217 from 233.
Include the next digit (0) from the dividend after 16, then repeat: 160 / 31

Advancing to step 5:
The number 31 fits into 160 5 times, leaving a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 1975.0
If we subtract 155 from 160, we get 5.
Include the next digit (8) from the dividend after 5, then repeat: 58 / 31

Moving on to step 6:
31 can be fit into 58 1 times, resulting in a remainder of 27.
Write down 1 as next digit of the result. 
Result so far: 19751.0
If we subtract 31 from 58, we get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

On to step 7:
If we divide 270 by 31, we get 8 and a remainder of 22.
Use 8 as the next digit of our solution. 
Result so far: 19751.8
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.

On to step 8:
When dividing 220 by 31, we get 7 with a remainder of 3.
Put 7 as the next digit of the answer. 
Result so far: 19751.87
The remainder is 3 after subtracting 217 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 9:
When dividing 30 by 31, we get 0 with a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 19751.87
If we subtract 0 from 30, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 10:
31 can be fit into 300 9 times, resulting in a remainder of 21.
Put 9 as the next digit of the answer. 
Result so far: 19751.8709
If we take 279 away from 300, we end up with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Moving on to step 11:
When dividing 210 by 31, we get 6 with a remainder of 24.
Record the quotient 6 as the next digit in the result. 
Result so far: 19751.87096
If we subtract 186 from 210, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 12:
If we divide 240 by 31, we get 7 and a remainder of 23.
Record the quotient 7 as the next digit in the result. 
Result so far: 19751.870967
If we take 217 away from 240, we end up with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Moving on to step 13:
When dividing 230 by 31, we get 7 with a remainder of 13.
Record the quotient 7 as the next digit in the result. 
Result so far: 19751.8709677
If we subtract 217 from 230, we get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Our division results in 19751.8709677 with a remaining 1.3e-07.
