Let's divide 631423 by 40
We want to divide 631423 by 40.

Let's proceed to step 1:
6 divided by 40 is 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Grab the next digit (3) from the dividend, add it to 6, then carry on: 63 / 40

Going ahead to step 2:
When dividing 63 by 40, we get 1 with a remainder of 23.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 40 from 63 to get 23.
Append the next digit (1) from the dividend to 23 and continue with: 231 / 40

Step 3:
40 goes into 231 5 times with a remainder of 31.
The next digit of our result is 5. 
Result so far: 15.0
If we subtract 200 from 231, we get 31.
Take the next digit (4) from the dividend and append it to 31, then repeat: 314 / 40

Advancing to step 4:
314 divided by 40 is 7 with a remainder of 34.
The next digit of our result is 7. 
Result so far: 157.0
Subtract 280 from 314 to get 34.
Bring next digit (2) of the dividend behind the 34 and repeat the process: 342 / 40

Let's proceed to step 5:
When dividing 342 by 40, we get 8 with a remainder of 22.
Use 8 as the next digit of our solution. 
Result so far: 1578.0
Subtracting 320 from 342 leaves us with 22.
Fetch the next digit (3) from the dividend, attach it to 22 and continue: 223 / 40

Moving on to step 6:
The number 40 fits into 223 5 times, leaving a remainder of 23.
The next digit of our result is 5. 
Result so far: 15785.0
The remainder is 23 after subtracting 200 from 223.
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 7:
If we divide 230 by 40, we get 5 and a remainder of 30.
Use 5 as the next digit of our solution. 
Result so far: 15785.5
Subtracting 200 from 230 leaves us 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.

Going ahead to step 8:
300 divided by 40 is 7 with a remainder of 20.
Put 7 as the next digit of the answer. 
Result so far: 15785.57
Deduct 280 from 300 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 9:
200 divided by 40 is 5 with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 15785.575
Deduct 200 from 200 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 10:
If we divide 0 by 40, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 15785.575
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 11:
40 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 15785.575
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 15785.575, with a leftover of 0.0.
