We look at the division of 619970 by 40 
Let's see how many times 40 fits into 619970.

Going ahead to step 1:
40 can be fit into 6 0 times, resulting in a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Include the next digit (1) from the dividend after 6, then repeat: 61 / 40

Moving on to step 2:
40 goes into 61 1 times with a remainder of 21.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 40 from 61 to get 21.
Append the next digit (9) from the dividend to 21 and continue with: 219 / 40

Let's proceed to step 3:
40 goes into 219 5 times with a remainder of 19.
Write down 5 as next digit of the result. 
Result so far: 15.0
Subtracting 200 from 219 leaves us with 19.
Grab the next digit (9) from the dividend, add it to 19, then carry on: 199 / 40

Let's proceed to step 4:
40 can be fit into 199 4 times, resulting in a remainder of 39.
Write down 4 as next digit of the result. 
Result so far: 154.0
Subtracting 160 from 199 leaves us with 39.
Fetch the next digit (7) from the dividend, attach it to 39 and continue: 397 / 40

Going ahead to step 5:
When dividing 397 by 40, we get 9 with a remainder of 37.
Write down 9 as next digit of the result. 
Result so far: 1549.0
Subtract 360 from 397 to get 37.
Take the next digit (0) from the dividend and append it to 37, then repeat: 370 / 40

Moving on to step 6:
370 divided by 40 is 9 with a remainder of 10.
The number 9 becomes the next digit in our result. 
Result so far: 15499.0
The remainder is 10 after subtracting 360 from 370.
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 7:
100 divided by 40 is 2 with a remainder of 20.
Write down 2 as next digit of the result. 
Result so far: 15499.2
If we subtract 80 from 100, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 8:
40 can be fit into 200 5 times, resulting in a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 15499.25
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.

Moving on to step 9:
When dividing 0 by 40, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 15499.25
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.

Moving on to step 10:
If we divide 0 by 40, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 15499.25
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.

After the division, we end up with 15499.25 and a remainder of 0.0.
