We look at the division of 448170 by 31 
We're looking to find how many times 31 goes into 448170.

Advancing to step 1:
31 goes into 4 0 times with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Bring next digit (4) of the dividend behind the 4 and repeat the process: 44 / 31

Let's proceed to step 2:
If we divide 44 by 31, we get 1 and a remainder of 13.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 31 from 44 and we're left with 13.
Bring next digit (8) of the dividend behind the 13 and repeat the process: 138 / 31

On to step 3:
The number 31 fits into 138 4 times, leaving a remainder of 14.
Put 4 as the next digit of the answer. 
Result so far: 14.0
If we subtract 124 from 138, we get 14.
Append the next digit (1) from the dividend to 14 and continue with: 141 / 31

Moving on to step 4:
When dividing 141 by 31, we get 4 with a remainder of 17.
The number 4 becomes the next digit in our result. 
Result so far: 144.0
Subtract 124 from 141 to get 17.
Grab the next digit (7) from the dividend, add it to 17, then carry on: 177 / 31

Let's proceed to step 5:
When dividing 177 by 31, we get 5 with a remainder of 22.
The next digit of our result is 5. 
Result so far: 1445.0
If we take 155 away from 177, we end up with 22.
Take the next digit (0) from the dividend and append it to 22, then repeat: 220 / 31

Going ahead to step 6:
220 divided by 31 is 7 with a remainder of 3.
Put 7 as the next digit of the answer. 
Result so far: 14457.0
Subtract 217 from 220 to get 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 7:
If we divide 30 by 31, we get 0 and a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 14457.0
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 8:
If we divide 300 by 31, we get 9 and a remainder of 21.
Put 9 as the next digit of the answer. 
Result so far: 14457.09
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.

On to step 9:
210 divided by 31 is 6 with a remainder of 24.
Put 6 as the next digit of the answer. 
Result so far: 14457.096
Deduct 186 from 210 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 10:
If we divide 240 by 31, we get 7 and a remainder of 23.
Put 7 as the next digit of the answer. 
Result so far: 14457.0967
If we subtract 217 from 240, we 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.

Advancing to step 11:
31 goes into 230 7 times with a remainder of 13.
The number 7 becomes the next digit in our result. 
Result so far: 14457.09677
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.

The final outcome is 14457.09677, with a leftover of 1.3e-05.
