Let's divide 57449130 by 40
We want to figure out the number of times 57449130 can be divided by 40.

Moving on to step 1:
5 divided by 40 is 0 with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Fetch the next digit (7) from the dividend, attach it to 5 and continue: 57 / 40

Moving on to step 2:
57 divided by 40 is 1 with a remainder of 17.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 40 from 57 leaves us with 17.
Fetch the next digit (4) from the dividend, attach it to 17 and continue: 174 / 40

Let's proceed to step 3:
40 can be fit into 174 4 times, resulting in a remainder of 14.
The next digit of our result is 4. 
Result so far: 14.0
Subtract 160 from 174 to get 14.
Fetch the next digit (4) from the dividend, attach it to 14 and continue: 144 / 40

On to step 4:
If we divide 144 by 40, we get 3 and a remainder of 24.
Put 3 as the next digit of the answer. 
Result so far: 143.0
Subtracting 120 from 144 leaves us with 24.
Grab the next digit (9) from the dividend, add it to 24, then carry on: 249 / 40

Step 5:
40 can be fit into 249 6 times, resulting in a remainder of 9.
Use 6 as the next digit of our solution. 
Result so far: 1436.0
The remainder is 9 after subtracting 240 from 249.
Append the next digit (1) from the dividend to 9 and continue with: 91 / 40

Let's proceed to step 6:
91 divided by 40 is 2 with a remainder of 11.
Use 2 as the next digit of our solution. 
Result so far: 14362.0
Subtract 80 from 91 to get 11.
Grab the next digit (3) from the dividend, add it to 11, then carry on: 113 / 40

Moving on to step 7:
The number 40 fits into 113 2 times, leaving a remainder of 33.
Record the quotient 2 as the next digit in the result. 
Result so far: 143622.0
Subtract 80 from 113 to get 33.
Bring next digit (0) of the dividend behind the 33 and repeat the process: 330 / 40

Let's proceed to step 8:
When dividing 330 by 40, we get 8 with a remainder of 10.
Write down 8 as next digit of the result. 
Result so far: 1436228.0
Subtract 320 from 330 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.

Going ahead to step 9:
When dividing 100 by 40, we get 2 with a remainder of 20.
The next digit of our result is 2. 
Result so far: 1436228.2
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 10:
If we divide 200 by 40, we get 5 and a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 1436228.25
Subtract 200 from 200 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 11:
40 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 1436228.25
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 12:
40 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 1436228.25
Deduct 0 from 0 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.

The final outcome is 1436228.25, with a leftover of 0.0.
