620739 ÷ 40 
We're looking to find how many times 40 goes into 620739.

Advancing to step 1:
6 divided by 40 is 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Include the next digit (2) from the dividend after 6, then repeat: 62 / 40

Let's proceed to step 2:
40 goes into 62 1 times with a remainder of 22.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 40 away from 62, we end up with 22.
Include the next digit (0) from the dividend after 22, then repeat: 220 / 40

Let's proceed to step 3:
40 goes into 220 5 times with a remainder of 20.
Use 5 as the next digit of our solution. 
Result so far: 15.0
Deduct 200 from 220 and we're left with 20.
Include the next digit (7) from the dividend after 20, then repeat: 207 / 40

Going ahead to step 4:
40 goes into 207 5 times with a remainder of 7.
Record the quotient 5 as the next digit in the result. 
Result so far: 155.0
If we take 200 away from 207, we end up with 7.
Append the next digit (3) from the dividend to 7 and continue with: 73 / 40

Going ahead to step 5:
If we divide 73 by 40, we get 1 and a remainder of 33.
Use 1 as the next digit of our solution. 
Result so far: 1551.0
Subtract 40 from 73 to get 33.
Fetch the next digit (9) from the dividend, attach it to 33 and continue: 339 / 40

On to step 6:
339 divided by 40 is 8 with a remainder of 19.
The next digit of our result is 8. 
Result so far: 15518.0
Subtracting 320 from 339 leaves us 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.

Going ahead to step 7:
40 can be fit into 190 4 times, resulting in a remainder of 30.
The next digit of our result is 4. 
Result so far: 15518.4
Subtracting 160 from 190 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.

Let's proceed to step 8:
40 can be fit into 300 7 times, resulting in a remainder of 20.
Record the quotient 7 as the next digit in the result. 
Result so far: 15518.47
Subtracting 280 from 300 leaves us 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.

On to 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: 15518.475
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.

Let's proceed to step 10:
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: 15518.475
If we subtract 0 from 0, we 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.

Advancing to step 11:
The number 40 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 15518.475
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.

Our division results in 15518.475 with a remaining 0.0.
