31807454 ÷ 126 
We want to figure out the number of times 31807454 can be divided by 126.

Advancing to step 1:
If we divide 3 by 126, we get 0 and a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Include the next digit (1) from the dividend after 3, then repeat: 31 / 126

Let's proceed to step 2:
126 goes into 31 0 times with a remainder of 31.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 31 leaves us with 31.
Take the next digit (8) from the dividend and append it to 31, then repeat: 318 / 126

Let's proceed to step 3:
If we divide 318 by 126, we get 2 and a remainder of 66.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
The remainder is 66 after subtracting 252 from 318.
Append the next digit (0) from the dividend to 66 and continue with: 660 / 126

Let's proceed to step 4:
126 goes into 660 5 times with a remainder of 30.
The next digit of our result is 5. 
Result so far: 25.0
If we take 630 away from 660, we end up with 30.
Grab the next digit (7) from the dividend, add it to 30, then carry on: 307 / 126

Advancing to step 5:
126 can be fit into 307 2 times, resulting in a remainder of 55.
The next digit of our result is 2. 
Result so far: 252.0
The remainder is 55 after subtracting 252 from 307.
Append the next digit (4) from the dividend to 55 and continue with: 554 / 126

On to step 6:
126 can be fit into 554 4 times, resulting in a remainder of 50.
The number 4 becomes the next digit in our result. 
Result so far: 2524.0
Subtracting 504 from 554 leaves us with 50.
Append the next digit (5) from the dividend to 50 and continue with: 505 / 126

On to step 7:
126 goes into 505 4 times with a remainder of 1.
Use 4 as the next digit of our solution. 
Result so far: 25244.0
The remainder is 1 after subtracting 504 from 505.
Bring next digit (4) of the dividend behind the 1 and repeat the process: 14 / 126

Going ahead to step 8:
14 divided by 126 is 0 with a remainder of 14.
The number 0 becomes the next digit in our result. 
Result so far: 252440.0
If we take 0 away from 14, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 9:
If we divide 140 by 126, we get 1 and a remainder of 14.
Put 1 as the next digit of the answer. 
Result so far: 252440.1
Subtracting 126 from 140 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 10:
If we divide 140 by 126, we get 1 and a remainder of 14.
Record the quotient 1 as the next digit in the result. 
Result so far: 252440.11
If we take 126 away from 140, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

The final result is 252440.11 with a remainder of 0.014.
