Let's divide 491625 by 31
We want to figure out the number of times 491625 can be divided by 31.

Advancing to step 1:
When dividing 4 by 31, we get 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Include the next digit (9) from the dividend after 4, then repeat: 49 / 31

Step 2:
The number 31 fits into 49 1 times, leaving a remainder of 18.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 31 from 49 to get 18.
Grab the next digit (1) from the dividend, add it to 18, then carry on: 181 / 31

Step 3:
If we divide 181 by 31, we get 5 and a remainder of 26.
Put 5 as the next digit of the answer. 
Result so far: 15.0
Subtracting 155 from 181 leaves us with 26.
Bring next digit (6) of the dividend behind the 26 and repeat the process: 266 / 31

On to step 4:
The number 31 fits into 266 8 times, leaving a remainder of 18.
Write down 8 as next digit of the result. 
Result so far: 158.0
If we subtract 248 from 266, we get 18.
Include the next digit (2) from the dividend after 18, then repeat: 182 / 31

Advancing to step 5:
The number 31 fits into 182 5 times, leaving a remainder of 27.
Put 5 as the next digit of the answer. 
Result so far: 1585.0
The remainder is 27 after subtracting 155 from 182.
Take the next digit (5) from the dividend and append it to 27, then repeat: 275 / 31

Advancing to step 6:
If we divide 275 by 31, we get 8 and a remainder of 27.
Use 8 as the next digit of our solution. 
Result so far: 15858.0
If we subtract 248 from 275, 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.

Going ahead to step 7:
If we divide 270 by 31, we get 8 and a remainder of 22.
The number 8 becomes the next digit in our result. 
Result so far: 15858.8
Subtract 248 from 270 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 8:
31 goes into 220 7 times with a remainder of 3.
The next digit of our result is 7. 
Result so far: 15858.87
Subtracting 217 from 220 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 9:
If we divide 30 by 31, we get 0 and a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 15858.87
Deduct 0 from 30 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 10:
300 divided by 31 is 9 with a remainder of 21.
Write down 9 as next digit of the result. 
Result so far: 15858.8709
Subtracting 279 from 300 leaves us 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.

Advancing to step 11:
31 can be fit into 210 6 times, resulting in a remainder of 24.
Use 6 as the next digit of our solution. 
Result so far: 15858.87096
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.

Moving on to step 12:
31 can be fit into 240 7 times, resulting in a remainder of 23.
The next digit of our result is 7. 
Result so far: 15858.870967
Subtract 217 from 240 to get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

On to step 13:
31 goes into 230 7 times with a remainder of 13.
Record the quotient 7 as the next digit in the result. 
Result so far: 15858.8709677
The remainder is 13 after subtracting 217 from 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

The final outcome is 15858.8709677, with a leftover of 1.3e-07.
