We look at the division of 31391605 by 492 
Let's see how many times 492 fits into 31391605.

Advancing to step 1:
492 can be fit into 3 0 times, resulting in a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Append the next digit (1) from the dividend to 3 and continue with: 31 / 492

Going ahead to step 2:
If we divide 31 by 492, we get 0 and a remainder of 31.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 31 leaves us with 31.
Grab the next digit (3) from the dividend, add it to 31, then carry on: 313 / 492

Going ahead to step 3:
492 can be fit into 313 0 times, resulting in a remainder of 313.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 313, we get 313.
Take the next digit (9) from the dividend and append it to 313, then repeat: 3139 / 492

Going ahead to step 4:
When dividing 3139 by 492, we get 6 with a remainder of 187.
The next digit of our result is 6. 
Result so far: 6.0
If we subtract 2952 from 3139, we get 187.
Bring next digit (1) of the dividend behind the 187 and repeat the process: 1871 / 492

Let's proceed to step 5:
492 goes into 1871 3 times with a remainder of 395.
Write down 3 as next digit of the result. 
Result so far: 63.0
The remainder is 395 after subtracting 1476 from 1871.
Take the next digit (6) from the dividend and append it to 395, then repeat: 3956 / 492

Advancing to step 6:
When dividing 3956 by 492, we get 8 with a remainder of 20.
Use 8 as the next digit of our solution. 
Result so far: 638.0
If we take 3936 away from 3956, we end up with 20.
Bring next digit (0) of the dividend behind the 20 and repeat the process: 200 / 492

Moving on to step 7:
492 goes into 200 0 times with a remainder of 200.
Write down 0 as next digit of the result. 
Result so far: 6380.0
Subtract 0 from 200 to get 200.
Append the next digit (5) from the dividend to 200 and continue with: 2005 / 492

On to step 8:
When dividing 2005 by 492, we get 4 with a remainder of 37.
Write down 4 as next digit of the result. 
Result so far: 63804.0
Deduct 1968 from 2005 and we're left with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Going ahead to step 9:
492 goes into 370 0 times with a remainder of 370.
Put 0 as the next digit of the answer. 
Result so far: 63804.0
If we take 0 away from 370, we end up with 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3700, and continue the process.

On to step 10:
If we divide 3700 by 492, we get 7 and a remainder of 256.
Record the quotient 7 as the next digit in the result. 
Result so far: 63804.07
If we take 3444 away from 3700, we end up with 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

Going ahead to step 11:
If we divide 2560 by 492, we get 5 and a remainder of 100.
The number 5 becomes the next digit in our result. 
Result so far: 63804.075
Deduct 2460 from 2560 and we're left with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Advancing to step 12:
The number 492 fits into 1000 2 times, leaving a remainder of 16.
Use 2 as the next digit of our solution. 
Result so far: 63804.0752
Deduct 984 from 1000 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.

Step 13:
492 can be fit into 160 0 times, resulting in a remainder of 160.
Write down 0 as next digit of the result. 
Result so far: 63804.0752
If we subtract 0 from 160, we get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Step 14:
492 goes into 1600 3 times with a remainder of 124.
Record the quotient 3 as the next digit in the result. 
Result so far: 63804.075203
If we subtract 1476 from 1600, we get 124.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

On to step 15:
1240 divided by 492 is 2 with a remainder of 256.
Write down 2 as next digit of the result. 
Result so far: 63804.0752032
If we subtract 984 from 1240, we get 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

Advancing to step 16:
If we divide 2560 by 492, we get 5 and a remainder of 100.
The number 5 becomes the next digit in our result. 
Result so far: 63804.07520325
The remainder is 100 after subtracting 2460 from 2560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

After the division, we end up with 63804.07520325 and a remainder of 1e-07.
