We're dividing 621019 by 40 
We want to figure out the number of times 621019 can be divided by 40.

Let's proceed to step 1:
When dividing 6 by 40, we get 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Bring next digit (2) of the dividend behind the 6 and repeat the process: 62 / 40

Let's proceed to step 2:
40 can be fit into 62 1 times, resulting in a remainder of 22.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 40 from 62, we get 22.
Take the next digit (1) from the dividend and append it to 22, then repeat: 221 / 40

Step 3:
The number 40 fits into 221 5 times, leaving a remainder of 21.
Write down 5 as next digit of the result. 
Result so far: 15.0
Deduct 200 from 221 and we're left with 21.
Take the next digit (0) from the dividend and append it to 21, then repeat: 210 / 40

On to step 4:
210 divided by 40 is 5 with a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 155.0
Subtract 200 from 210 to get 10.
Grab the next digit (1) from the dividend, add it to 10, then carry on: 101 / 40

Let's proceed to step 5:
When dividing 101 by 40, we get 2 with a remainder of 21.
The next digit of our result is 2. 
Result so far: 1552.0
The remainder is 21 after subtracting 80 from 101.
Fetch the next digit (9) from the dividend, attach it to 21 and continue: 219 / 40

Let's proceed to step 6:
40 can be fit into 219 5 times, resulting in a remainder of 19.
The number 5 becomes the next digit in our result. 
Result so far: 15525.0
Deduct 200 from 219 and we're left with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Advancing to step 7:
190 divided by 40 is 4 with a remainder of 30.
Put 4 as the next digit of the answer. 
Result so far: 15525.4
If we subtract 160 from 190, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 8:
40 goes into 300 7 times with a remainder of 20.
Write down 7 as next digit of the result. 
Result so far: 15525.47
Subtract 280 from 300 to 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.

Moving on to step 9:
40 goes into 200 5 times with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 15525.475
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.

Step 10:
When dividing 0 by 40, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 15525.475
Subtracting 0 from 0 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.

Step 11:
40 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 15525.475
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 15525.475, with a leftover of 0.0.
