Let's divide 19120401 by 40
We're looking to find how many times 40 goes into 19120401.

Going ahead to step 1:
40 can be fit into 1 0 times, resulting in a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Take the next digit (9) from the dividend and append it to 1, then repeat: 19 / 40

Let's proceed to step 2:
The number 40 fits into 19 0 times, leaving a remainder of 19.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 19 leaves us with 19.
Bring next digit (1) of the dividend behind the 19 and repeat the process: 191 / 40

Going ahead to step 3:
The number 40 fits into 191 4 times, leaving a remainder of 31.
Use 4 as the next digit of our solution. 
Result so far: 4.0
If we take 160 away from 191, we end up with 31.
Fetch the next digit (2) from the dividend, attach it to 31 and continue: 312 / 40

Let's proceed to step 4:
The number 40 fits into 312 7 times, leaving a remainder of 32.
The number 7 becomes the next digit in our result. 
Result so far: 47.0
Deduct 280 from 312 and we're left with 32.
Take the next digit (0) from the dividend and append it to 32, then repeat: 320 / 40

Let's proceed to step 5:
40 can be fit into 320 8 times, resulting in a remainder of 0.
Put 8 as the next digit of the answer. 
Result so far: 478.0
Subtracting 320 from 320 leaves us with 0.
Grab the next digit (4) from the dividend, add it to 0, then carry on: 4 / 40

Moving on to step 6:
4 divided by 40 is 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 4780.0
Subtract 0 from 4 to get 4.
Bring next digit (0) of the dividend behind the 4 and repeat the process: 40 / 40

Let's proceed to step 7:
If we divide 40 by 40, we get 1 and a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 47801.0
If we take 40 away from 40, we end up with 0.
Bring next digit (1) of the dividend behind the 0 and repeat the process: 1 / 40

Going ahead to step 8:
The number 40 fits into 1 0 times, leaving a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 478010.0
Subtracting 0 from 1 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 9:
When dividing 10 by 40, we get 0 with a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 478010.0
Subtract 0 from 10 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 10:
40 goes into 100 2 times with a remainder of 20.
Use 2 as the next digit of our solution. 
Result so far: 478010.02
The remainder is 20 after subtracting 80 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 11:
40 goes into 200 5 times with a remainder of 0.
The next digit of our result is 5. 
Result so far: 478010.025
Subtracting 200 from 200 leaves us 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.

Going ahead to step 12:
40 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 478010.025
Subtract 0 from 0 to get 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 13:
40 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 478010.025
If we take 0 away from 0, we end up 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.

The final outcome is 478010.025, with a leftover of 0.0.
