We look at the division of 31352099 by 246 
We're looking to find how many times 246 goes into 31352099.

On to step 1:
The number 246 fits into 3 0 times, leaving a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Include the next digit (1) from the dividend after 3, then repeat: 31 / 246

Going ahead to step 2:
When dividing 31 by 246, we get 0 with a remainder of 31.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 31, we end up with 31.
Bring next digit (3) of the dividend behind the 31 and repeat the process: 313 / 246

On to step 3:
The number 246 fits into 313 1 times, leaving a remainder of 67.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 246 from 313, we get 67.
Grab the next digit (5) from the dividend, add it to 67, then carry on: 675 / 246

Going ahead to step 4:
If we divide 675 by 246, we get 2 and a remainder of 183.
Write down 2 as next digit of the result. 
Result so far: 12.0
If we take 492 away from 675, we end up with 183.
Include the next digit (2) from the dividend after 183, then repeat: 1832 / 246

Let's proceed to step 5:
If we divide 1832 by 246, we get 7 and a remainder of 110.
Record the quotient 7 as the next digit in the result. 
Result so far: 127.0
Deduct 1722 from 1832 and we're left with 110.
Grab the next digit (0) from the dividend, add it to 110, then carry on: 1100 / 246

Moving on to step 6:
246 can be fit into 1100 4 times, resulting in a remainder of 116.
Record the quotient 4 as the next digit in the result. 
Result so far: 1274.0
If we subtract 984 from 1100, we get 116.
Fetch the next digit (9) from the dividend, attach it to 116 and continue: 1169 / 246

Going ahead to step 7:
If we divide 1169 by 246, we get 4 and a remainder of 185.
Use 4 as the next digit of our solution. 
Result so far: 12744.0
Subtracting 984 from 1169 leaves us with 185.
Bring next digit (9) of the dividend behind the 185 and repeat the process: 1859 / 246

Let's proceed to step 8:
The number 246 fits into 1859 7 times, leaving a remainder of 137.
Record the quotient 7 as the next digit in the result. 
Result so far: 127447.0
The remainder is 137 after subtracting 1722 from 1859.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1370, and continue the process.

Let's proceed to step 9:
If we divide 1370 by 246, we get 5 and a remainder of 140.
The number 5 becomes the next digit in our result. 
Result so far: 127447.5
Deduct 1230 from 1370 and we're left with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Moving on to step 10:
246 can be fit into 1400 5 times, resulting in a remainder of 170.
The next digit of our result is 5. 
Result so far: 127447.55
If we subtract 1230 from 1400, we get 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Our division results in 127447.55 with a remaining 0.17.
